Definition of BIM

Unfortunately, there is currently no industry standard agreed definition

of BIM , the definition of BIM is best described by Graphisoft, which

describes BIM as three separate but linked activities:

Building Information MODELLING

Is a business process that allows all stakeholders to have access to the

same information at the same time through seamless interoperability

between technology platforms.

Building Information MODEL

Is the output of the business process, a virtual computer model of a

project that holds selected data (design, quantity, time, cost, asset etc.)

Building Information MANAGEMENT

Provides the benefits that can be divided from The Building Information

Model. These include centralized and visual communication,sustainability, efficient design integration of other disciplines, site

control, as built documentation etc.

The "I" in BIM is sometimes even more compelling in BIM, think about

cost estimating test, think about specification writing, think about

energy load analysis, think about heating and cooling, think about

structural loads, all this things require data, we have this data instead

of manually computing all of this various things that we need to get a

paper design, why not let the computer do while computer do best?, so

this is what BIM is all about, again let's focus just in "M", let us also

think about the "I" and if we have got the two together and fully

coordinate the package in a way that Revit would give us, then what

we have got is a fully implemented BIM solution Buildings are morecomplex than ever before. Documentation sets span all disciplines, and

are hundreds of pages long. The numbers of people that will touch a

set of drawingsto produce them, evaluate them, or use them to build

the buildinghave become huge. Integrated building systems continue

to expand with the growth of technology. Today, we have more


12/127

security, electrical, data, telecom, HVAC, and energy requirement than

ever before.

Building Information Modeling or BIM brings with it many

advantages for the digital design of buildings. Yet with BIM comes

issues and risks that a design professional must consider. Enhanced

usage of electronic design and construction processes holds

promises for saving Time and money, reducing claims and increasing

the quality of performance, especially on complex projects. One

must consider and recognize however the individual risks associated

with this new process. Building information modeling supports the

continuous and immediate availability of project design scope,

schedule, and cost information that is high quality, reliable,

integrated, and fully coordinated.

Building Information Modeling Benefits:

Building information modeling supports the continuous and immediate

availability of project design scope, schedule, and cost information that is

high quality, reliable, integrated, and fully coordinated. Among the many

competitive advantages it confers are:

Increased speed of delivery (time saved).

construction industry has been studied by the Construction Industry

Institute and Lean Construction Institute who have found that waste

accounts for 57% of money lost in the construction industry and 26%

in the manufacturing sector. This 2008 data shows that there was a

$400 billion aggregate loss resulting from such factors as

miscommunication among project partners and informational

inaccuracies which BIM can catch and prevent.1 Thus the

construction industry is starting to implement BIM and building

owners as well can reap the benefits.

Greater productivity.

BIM assists to incorporate facility performance with user assessments. The

results from user assessment studies and instrument measures of the

physical condition of the building can easily be allotted on floor plans

utilizing geographic information systems. The construction firms may link

these data to their geographic information systems for future planning and

design purposes.


19/127

16

Higher-quality work.

BIM provides object-oriented models with rich semantics and relationships

encoded, supporting the automated analysis of the performance of building

products and designs. This basically leads to improved design,

implementation and management at all stages of the buildings life cycle.

BIM afford manufacturers, designers and integrators advantages in design

efficiency and quality control. A single, connected model improves

communication within the design and construction teams and the

parametric elements of the model create a robust database. The Building

owner and facility manager can utilize the data within the model during the

Occupation of the building. Harvesting the information in that data base

can help everyone be more efficient and also create new opportunities for

revenue expansion.

What Is Revit Structure?

Revit Structure is a modeling program. This means that everything placed into

a model simulates a true building material. It is important to note that thereis a distinct difference between the term modeling and the term 3D. While

Revit Structure has many advanced 3D capabilities, it is foremost a modeling

program. Most of your modeling occurs in a 2D environment, with 3D views

easily accessible at any time.

BIM and Structural Engineering

BIM stands for Building Information Modeling. BIM is the process of creating

a single, database-driven model by placing actual building components and

materials. Therefore, for the structural engineer and designer the BIM model

does not stop at the actual building. Since the components used in the model

represent real-life members, you can design for stresses as you draft and vice-

versa. Additionally, in a Revit/BIM environment when beams are attached to

columns, and columns to grids, the application understands that these

elements belong together. In plan, if a gridline moves, so do the columns and

subsequently the beams. In elevation, if a level moves, the columns increase

in length and any framing on that floor moves with it. Revit also

automatically updates the column schedule to reflect the change.

Drawings are now based on a model that is as close to an actual building as

possible. A design change can influence the building in another area. This is

known as parametric design. The move to this kind of modeling is becoming


22/127

19

the industry standard. As BIM applications become smarter, so does the

industry.

Revit Structure Projects

A project is a complete description of a building and the information

associated with it for displaying 2D and 3D views, as well as schedules. When

you open a Revit Structure project file, it opens the entire project or building

model. You can then work in different views, such as plan, section, elevation,

and 3D model, all within the same project file.

All of the views are associative. Changes to the model in one view are

automatically updated in all other views. For example, if you add an

opening to a wall in a plan view, it also appears in the related

elevation view and any related schedules (such as a lintel schedule).

You can place the views on sheets in a Revit Structure project to

create construction drawings. Callouts of details and elevations can

be automated with tags and titles on the sheets.


23/127

20

File Types

The following explains each Revit file type:

.RVT The file format of a Revit model. There are three separate Revit

applications: Revit Structure, Revit Architecture, and Revit MEP. Each of

these applications saves a standard project file as the RVT format. Each

file can be opened directly in any of the three applications. RVT files can

also be inserted and linked into one another. This is crucial for

coordination between disciplines. If groups of objects are created and

saved out separately, they are also in the RVT format.

.RFA The file format of a Revit Family. These files can be opened directly,

inserted, or loaded into an RVT file.

.RTE The Revit project template file. When a new model is started, an RTE file

is used to create the model. When you save the file, it is saved as a new

RVT model. This file contains all of your companys standards and

settings. Views, sheets, and families should be set up and ready to use inthe project template.

.RFT The Revit family template file. When a new family is started, an RFT file

is used to create the family. You can use a default or custom template.

When saved, the file becomes a new RFA family. You can customize the

family template to include commonly used reference planes,

parameters, etc.


24/127

21

Types of Elements

There are five main types of elements in a Revit Structure project, as

explained below:

Host elements are the built-in-placeconstruction objects, such as floors, walls,

roofs, ceilings, stairs, and ramps. They can stand alone in the project.

Component Component elements are objects that need to be attached to

host elements, such as openings, reinforcing, and footings, as

well as stand-alone elements, such as columns, beams andequipment.

View Views enable you to see and manipulate the project. For

example, you can view and work in floor plans, ceiling plans,

elevations, sections, schedules, and 3D views. You can change

a design from any view. All views are stored in the project.

Datum Datum elements define the project context. These include

levels for the floors, column grids, and reference planes that

help you draw.

Annotation Annotation elements are 2D objects that you place on views to

define the information drawn in the project. These include

dimensions, text, tags, and symbols. The view scale controls

their size.


25/127

The Revit Structure Interface

Revit Structure models are entirely driven by placing components; therefore,

the interface is different from the AutoCAD interface. There is no command

prompt, no layers, and fewer icons. Revit Structure is an application designed

solely for structural design. The Revit Structure

interface is designed for intuitive and efficient access to commands and

views. It includes the Ribbon, Quick Access Toolbar, Application Menu, and

Status Bar, which are common to newer versions of all Autodesk software. It

also includes tools that are specific to Revit Structure, including the Project

Browser and View Control Bar. The interface is shown below.


26/127

23

1. Quick Access Toolbar

The Quick Access Toolbar provides access to commonly used commands,

such as Open, Save, Undo and Redo, Modify, and 3D View, as shown

below. You can also customize this toolbar by adding commands from any

of the Ribbon tabs.

2. InfoCenter

The InfoCenter enables you to quickly search for help on the web, as

shown below. You can specify which Help documents to search, and

collapse or expand the Search field to save screen space.

3. Application MenuThe Application Menu provides access to file commands, settings, and

documents, as shown below. Hover your cursor over a command to see a list

of additional tools.

If you click the primary icon rather than the arrow, it starts the

default command.


27/127

24


28/127

25

Recent and Open Drawings

To see a list of recently used documents, click (Recent Documents) in

the Application menu. The documents can be reordered, as shown in the

image below.

Click (Pin) next to a document name to keep it available and to prevent it

from dropping off the bottom of the list as more recent documents appear on

the list. When a file has been pinned, it will display with the push

pin tacked in

4. Ribbon

The Ribbon contains Revit Structure tools in a series of tabs and panels, as

shown in the image below. Selecting a tab displays a group of related panels.

The panels contain a variety of tools, grouped by function.


29/127

26

Contextual Tabs

When you select a command that creates new elements for example concrete

beam , the Ribbon switches to a contextual tab. The tab includes Element

Properties, the pull-down menu, and general commands for creating the

element, as shown in the image below.

When you select an existing element in Revit Structure, the Ribbon switches to

a contextual tab that includes general editing commands as well as

commands directly related to the element type, as shown below.

5. Options Bar

The Options Bar changes according to the selected command or element. For

example, when the Beam command is active, it displays options for placing

the beam, as shown below.


30/127

27

6. TooltipsTooltips display the elements name, a short description, and sometimes a

graphic, as shown below. They provide information about tools, commands,

and how to create specific elements.

Many commands have shortcut keys.

For example, type BM for Beam or CL

for Structural Column. They are listed

next to the name of the command in

the tooltips.

NOTE: You do not need to press

to execute two-lettershortcuts.

7. Project BrowserThe Project Browser lists the views of each

project that can be opened in Revit Structure as

shown in the image below. This includes all

views of the model that you are working in and

any additional views you create (such as floor

plans, 3D views, elevations, sections, etc.). It

also includes views of schedules, legends,

sheets (for plotting), families (such as beams

and walls), and groups and links.


31/127

28

8. View Windows

Each view of a project opens in its own window, as shown below. The

views display a Navigation Bar for quick access to viewing tools and a

View Control Bar that controls aspects of that view (such as the scale,

detail level, and shading).

You can use the Project Browser, or press + to switch

between windows. Additional window tools (such as Cascade and Tile)

are found in the View tab>Windows panel in the Ribbon, as shown below.

Window Panel

Each model that is open can have multiple view windows open, which can

affect the speed at which Revit performs. It is recommended that only the

necessary windows remain open. To control this and reduce memory usage

,click (Close Hidden) in the View tab>Windows panel. To switch

between windows within the project, click Switch Windows, as shown below.

If multiple projects are open, these will also be displayed.


32/127

29

9. Status Bar

The Status Bar provides information about the current process, such as the

next step for a command, as shown below.

View Control Bar

The View Control Bar is at the bottom of the view window. This toolbar is

mainly responsible for the display of the model for a particular view.

Scale:Sets the scale of the view for plotting purposes, and controls the size

of annotations and symbols at the specified scale.

Detail Level: Determines the level in which thegraphics of an element are displayed. There are three

detail levels: Coarse, Medium, and Fine. Viewing a

model at a Fine detail level shows the most amount of

detail, but affects the speed at which you can pan and zoom the model.

Coarse, however, shows the least amount of detail within the elements ofthat view. For example steel column as shown below :

coarse( single line) medium(double line) fine (double line and curvature )


33/127

30

Model Graphics Style:

Determines the display style of the model. There are

four model graphics styles to select from:

Wireframe, Hidden Line, shading and Shading

with Edges.

Wireframe:All edges and lines are shown, and all surfaces are transparent. Use this for

plan views unless you want objects below to appear with hidden lines. This

display is not often used in 3D views as the wireframe display can make it

hard to understand the model.

Hidden:

Typically the first choice for plans and elevations. Most views are set to

Hidden line by default. Any obscured objects show as hidden line, while

objects that are not obscured show as continuous lines. This can sometimes

be controlled with the view range. Different displays in a typical foundation

plan view are shown below.

Wireframe Hidden


34/127

31

Shading:

Shown for 3D illustrations. It shades the model but does not show the lines

defining the objects being shaded. It can also be shown in elevation and plan,

but becomes cumbersome when it comes time to plot the model. Shading

with this graphical style is not recommended.

Shading with Edges:

The natural choice for 3D. It shades the model and leaves the outlined edges.

This mode is not recommended for plan or elevation, especially when plotting.

Typically, views placed on sheets use a simple hidden line graphics style.

Shading Shading with edge

Shadows:Used for presentations. Showing a shadowed

model slows the system dramatically.


35/127

32

Do Not Crop and Hide Crop Regionare designed to behave similarly to viewports in AutoCAD. Cropping a view

involves showing the crop region and moving the boundary to the desired

location. Column grid lines and bubbles will display regardless of the crop

boundary.

Temporary Hide/IsolateWe used it when need to temporarily hide or

isolate specific elements in a view. First, select

the elements you want to hide or isolate. Then,

click and select one of the four hide/isolate

choices, as shown below. This function only hides

elements in a view; it does not remove them

from the actual model nor does it hide them

permanently.

Reveal Hidden Elements

is used to reveal hidden elements. The icon turns magenta and a magenta box

surrounds the perimeter of the view. Normally visible elements are grayed

out, and the permanently hidden elements appear in magenta. If you want to

show these objects again, you can select them in this mode and click

(Unhide Elements) on the contextual tab>Reveal Hidden Elements panel.


36/127

33

Creating and Using Levels

Creating level one of the first steps we do at every structural project

but the arch. Engineer who is responsible for this task every project

except steel project we can start before arch. Engineer.

One of the greatest benefits to using Revit is the ability to control

datum elevations in real-time by using levels. Having this functionality

in a single model without the need for external referencing systems is

also advantageous. From a simple tool shed to a skyscraper, Revit is

designed to manage an entire project, not just parts of a building. By

adding and managing all of the buildings levels in a single file, Revit

increases efficiency in the typical workflow of a project. More time

can be spent designing and less time spent managing files and

folders.


37/127

34

To Create a Level :

1- To create level you have to go to any elevation at first to active level

icon and order.

2- In the Home tab>Datum panel, click (Level). The Ribbon

changes to the Place Level contextual tab and displays the optionsand tools you can use to create levels.

38/127

35

3-In the Draw panel click (Pick Lines).

4-Type 3000 in the Offsetfield in the Options Bar.

5- when you go to any elevation by default you will find level 1 and level 2

Move your cursor over the Level 2 elevation line. A blue dashed alignment line

appears. If you move your cursor to either side of the existing elevation line,

the alignment line moves with it. When you see the alignment line appear

above Level 2, select it. Level 3 appears.

3000

Level 3 a ears


39/127

36

6- when you click the level line and select it The following elements that

appear enable you to do the following:

The Checkmark icon that appears on either side of the bubble is

a toggle that controls whether the bubble and level information is

shown at that end of the level line.

The 3D icon controls whether any movement or adjustment is

reflect ted in other elevations. If you select this icon, it displays as 2D,

which means changes to that level would only affect the current view.

The Padlock icon controls whether the level is locked in alignment

with the other levels. If it is locked, you will see the blue dashed

alignment line. If level object is stretched, all other levels will stretch

with it. This helps maintain conventional drafting standards. If it is

unlocked, the level will stretch independently of the other levels.

The Blue open circle icon at the base of both sides of the datum

enables you to drag the level head to a new location.


40/127

37

The blue dimension that appears between the levels can be edited.

This is called a temporary dimension. Remember that any blue

element is editable or active.

The Dimension icon makes the temporary dimension permanent.

If this occurs, you can still modify the increment by selecting the level.

The permanent dimension temporarily turns blue enabling you to edit

the value.

The Add Elbow icon enables you to add a jog to the level line.

We use this option when you find two levels line very near and youneed to spate between them .

1 2 3

3000


41/127

38

7- to change the name of the level for example Rename Level 3 as Roof.

A message appears, asking if you want to rename the corresponding views.

Click yes.

The Level 3 view under Structural Plans located in the Project Browser

has also been renamed as Roof.

8- when we need to make level without plan ( non-plan view ) we can make it

as following:

In the Modify Levels contextual tab click copy andselect a

point anywhere along the Level 1 line. Move your cursor straight

down.

Select the Constrain ( this option as Ortho mode in AutoCAD ) and

Copy options in the Options Bar. Clear the Multiple option.

9. Type 2500 at the cursor.


42/127

39

10- Once the level is copied, rename it as T.O. Footing No additional floor plan

has been added to the Project Browser. This is because you only copied a

level. You did not create it using the conventional Level command. Therefore,

you need to create a floor plan based on the new level.

11-to create plan for this level make the following:

In the View tab>Create panel, expand Plan Views and select Structural Plan.

Select the T.O. Footing level in the New Plan dialog box.

A new floor plan now appears in the Project Browser.


43/127

40

Creating Grid

Grids are a very powerful (and consequently) useful feature within Revit Grids

are Annotation elements. That is, they are not part of your actual model- like

a wall, door or window would be. But they DO appear across different Views.

For example you can draw a grid on your ground floor plan and it would then

appear on the subsequent floors (ie Levels) of your model. The degree to

which the grid will appear in other views is dependent on its Extents- but

more about that later.

A grid line consist of two main parts. The grid line itself and the Grid Header

(ie the bubble at the end of the grid line). The default setting is for the grid

line to have a grid header at one end only. But you can have Grid Headers at

BOTH ends if you prefer. Just select a Grid line by clicking on it


44/127

41

1- where do we find the Grid command within Revit. Grids are right

there on the Home tab, in the Datum Panel

2-when you click grid icon The Ribbon changes to the Place Level

contextual tab and displays the options and tools you can use to create

Grid.

3-

from drawing tools we can start draw grid as straight line or curve orby pick line.

4- from drawing tools click straight line then the cursor will be in free

motion case and start to draw line at any place in drawing area

5- you can make anther grids by many options

array :

select grid line and from Ribbon chose array

When click array Contextual Tabs will appear by two options


45/127

42

1- 2nd this option to set the distance between the selecting grid and the

second grid

2- End this option to set the distance between selecting grid and the last

one

Note

in each option you have to set number of grids to array.


46/127

43

Grid line references (numbering / lettering)

Grid Lines are numbered automatically. The number (or Letter) increments

each time you draw a new one. The numbering of grid lines is very much

like the tagging of doors and windows. For example:- If your first grid line isnumbered 1, then Revit will number the rest of them 2, 3, 4, 5, etc.

But if you change your first grid line to A, Revit is clever enough to reference

subsequent grid lines as B, C, D, E, etc. You can override this automatic

referencing at any time by just clicking in the Grid Header and typing in the

number or letter you want for that particular grid line.

Controlling the grid spacing

So how do we get a series of grid lines onto a vew? The simplest method is to

simply draw the first Grid line and then use Multiple Copy to place the rest of

them. Do not worry about the spacing when you are placing new copies of the

gridlines. Ill show you a neat trick to quickly tidy up their spacing AFTER

you have placed them.

Heres 6 grid lines I have quickly created by copying the first one.


47/127

44

Grid Extents

What may not be apparent when you first start experimenting with Grids is

that they are in fact 3D planes. You can see this for yourself if you switch to

an elevation view.

Grid Line Offsets

Just like Levels, you can offset the Grid Header from its associated grid line, if

things start to get a bit too busy (ie grid headers are too bunched up). Just

select the grid line and then click on the Add Elbow icon just above the Grid

Header. You can see it just above the Add Albow Tool Tip in the image

below


48/127

45

Creating Columns

1- where do we find the column command within Revit. there on the

Home tab, in the structure Panel .

when we choose structure column new tab will appear to choose placing

options ( manual or at grid or at column )

if manual we chose location of column and place it.

if we have arch link choose at Arch columnsoption and select all arch

columns in link then structure columns will be create inside or overwrite Arch

columns.


49/127

46

Also we can chooseAt Gridoption to create columns by click in at grid on

multiple tab

When click at grid this tab (Column Options Bar )will appear to choose

direction of drawing column and levels


50/127

47

1- Select multiple grid intersections from right to left


51/127

48

Then click finish to finalize columns creation.

Note

Column will be placed at every intersection of selected grid lines,according to the properties set on the Options Bar. No columns are

actually created until you press the Finish button.


52/127

49

Press the SPACEBAR to rotate all of the columns that you are

creating.

Continue pressing SPACEBAR until the columns are in the desired

orientation.

When select any column you can see all properties of column from properties

tab .

Column base level and offset

Column top level and offset

Column material and etc )


53/127

50

Create Columns Sections

From properties tab you can choose column type from type selector

Drop-down and choose your type or create

new section from edit type.

To create new section you have two option

1-Rename

this option will modify the current

section to new section.

2-Duplicate

This option will make duplicate

from current section and then change

name and the parameters to new

section.


54/127

51

Creating Beam

Beams are structural elements used for load-bearing applications. Elements

of each beam are defined through the type properties of the specific beam

family. In addition, various instance properties can be modified to define the

functionality of the beam.

Sample beams

You can attach beams to any structural

element, including structural walls, in

your project. The beams join to

structural bearing walls when the

Structural Usage property of the wall is

set either to Bearing or to Structural

Combined.

Floor framing is a system that has horizontal beam elements supported by

vertical elements, such as walls and columns. Floor framing elements are

typically made of steel, wood, and concrete. They are added after the

columns and walls are placed in a model.


55/127

52

Examples of Floor Framing:

Steel beams supporting a composite concrete

slab on metal deck. The steel floor beams

transfer loads from the composite slab to steel

columns and masonry or concrete walls.

Cast-in-place concrete beams and pan joists

supporting a concrete slab. The concrete beams

and pan joists transfer loads from the concreteslab to the concrete columns. The concrete beams

and pan joists are cast monolithically with the slab

and columns.

Beam Properties

Beam properties are instance and type parameters

that define the characteristics of beams. You can

set values for beam properties to control the

representation of beams in a structural model.

After you select the Beam tool on the Structure

panel of the Home tab, you can use the Options

Bar to preset the beam properties.

Also you can make new sections for beam types as

column.


59/127

56

Options for Setting Beam Properties:

After you select the Beam tool, the Place Beam tab displays various options

for setting beam properties, as shown.

Additional options for setting beam properties are displayed on the Options

Bar, as shown.


60/127

57

Vertical Justification of Beams

You can set the vertical justification of a beam relative to its associated

reference level. Revit provides four options to define the vertical justification:

Top, Center, Bottom, and Other. By default, the top of a beam is set to a

reference level. After a beam is placed, you can change the vertical

justification. The following illustration shows precast beams set to Top,

Center, and Bottom justifications.

Z-Direction Offset

You can define the vertical justification of a beam relative to its associated

reference level using Z-Direction Justification in the Instance Properties dialog

box. The following illustration shows the options for Z-Direction Justification.


61/127

58

Structural usage values for beams

Beams are assigned a Structural Usage property based on their function in a

structural model. By default, Revit Structure assigns the Structural Usage

property to a beam automatically, based on the structural elements that

support the beam. However, after a beam is placed in a model, the structural

usages can be changed using the instance properties of the beam element.

The following table describes the structural usages that Revit automatically

assigns to beams.


62/127

59

Sloped beams

To adjust sloped beams

1. Select a beam that is connected to 2 structural members or warped

model objects at different heights.

2. Click Modify Structural Framing tab Element panel Element

Properties drop-down Instance Properties.

3. In the Instance Properties dialog, enter a value for the Start Level

Offset instance parameter of the beam.

4. Enter a value for the End Level Offset instance parameter of the beam,

and click OK.

5. Verify that you have entered the correct offset values.

Note

A beam that has adjusted offset values will

become disassociated or free from the

current work plane. Similarly, any

structural element attached to a slopedbeam will also become free. You attach

free elements to another work plane using

the existing Edit Work Plane or Rehost

buttons on the Work Plane panel of the

Modify Structural Framing tab.

Creating Beams systems

About Beams and Beam SystemsYou create beams in a structural model to connect various structural

elements. Beams can be placed in horizontal or vertical planes along straight

lines or along curved paths. To place beams, you use the Beam tool on the

Structure panel of the Home tab. To create more than one beam at a time,

you can create beam systems.

Methods for Creating Beam Systems

Using the Beam System tool on the Structure panel of the Home tab, you can

create a beam system in a structural model. To do this, select a support

formed by a closed loop of beams or structural walls. This method is called

the single-click placement method of creating beam systems. Another method

of creating a beam system is by sketching the outline of the beam system.

You can create 2D or 3D beam systems in the plan or 3D views. The 2D beam

systems are placed at the current level. In 3D beam systems, the elevation of

each beam is defined by the height and slope of the walls or by the beams

that support the beam system. In a 3D view, you can create 2D and 3D beam

systems by using the sketch method only. However, in a plan view, you can

also create 2D and 3D beams systems using the single-click placement

method.


64/127

61

Example of Beams and Beam Systems

The following illustrations show different beams and beam systems.

Beam System Properties

You can set the beam system properties before creating the beam system.

The following illustrations show the beam system options on the Options Bar.


65/127

62

The following table describes the beam system options.

Beam Type

Specifies the type of beams used in the beam system. The list displays the

same beam types as the Type Selector drop-down. You can load additional

beam types into the project if the beam you require is not in the Beam

Type list.

Justification

Specifies the justification type of the beam system as Beginning, Center, or

End.The justification type determines the placement of the first beam in the

beam system and each subsequent beam is spaced at a fixed distance from

that point.

Note:You can specify the justification only if you select the layout rule as

Fixed Distance.

Layout Rule

Specifies the pattern in which beams are arranged in a bay.

The layout rule can be of the following types:

Fixed Distance: Sets beams at a certain fixed distance from the

previous beam in the pattern.

Fixed Number: Sets a specified number of beams that are equally

spaced.

Maximum Spacing: Sets beams at a nominal spacing.

Clear Spacing: Same as Fixed Distance, but the spacing is measured

between the exteriors of the beams instead of between their centerlines. Withthe Clear Spacing layout rule, when you adjust the size of an individual beam


66/127

63

in a beam system, the beams next to it move to maintain the distance

between the beams.

3D

Specifies whether the beams in the beam system are planar or nonplanarwith respect to the current level.

If the 3D check box is not selected, the beams are placed planar with the

current level, regardless of whether the supporting members are sloped.

This is often referred to as a 2D beam system.

If the 3D check box is selected, the elevations at the ends of the beams are

controlled by the slope of the supporting members. This means that the

beams can accommodate different support heights and can be nonplanar

with the current level. This is often referred to as a 3D beam system.

Walls Define SlopeSpecifies the default value for the slope of the sketch lines that are

associated with walls in a beam system. You can set this property only for

sketch lines that have a wall as their support. When you set this property, the

heights are examined for the structural walls that outline the beam system

and then beams are placed accordingly.

Note:You can set this property only if you select the 3D Snapping check

box on the Options Bar.

TagPlaces a tag on either individual beams or a beam system.

Framing or SystemDefines the type of tag to be placed for a beam or a beam system.


67/127

64

When click Beam system you will find two options to create it

Automatic Beam System

We can use it when you have closed area and need to create

beam system

Direction of beam system is depending on the direction of the mouse

that is refereeing to .

If mouse referee to horizontal beam the beam systems will be in

horizontal direction And vice versa.


68/127

65

Sketch Beam System

This general option to create beam system for any area by sketch this area

and specify beam direction.

click sketch beam system and choose the tool of drawing to sketch

the area

beam direction

- to change beam direction click

beam direction and specify newdirection.


69/127

66

Structure wall

You create a structural wall by sketching the location line of the wall in a plan

or a 3D view. To do this, you need to first activate the Structural Wall tool

available in the Wall drop-down on the Structure panel of the Home tab.

Then, you can add walls by drawing them, selecting lines in a CAD file, or

selecting faces of mass objects.

Wall LayersWalls contain layers that correspond to the structure of wall systems. All

layers within the wall element have a definite purpose. For example, in a

metal stud over CMU wall type, the concrete masonry unit layer provides

structural support, the air and insulation layers act as thermal barriers, and

metal studs hold a gypsum wallboard finish. Each wall layer has specific

function, material, and thickness parameters, which you can modify based on

your requirements. Revit automatically detects the characteristics of each

layer and matches each characteristic to the appropriate function.

The following illustration shows the different wall layers in a structural wall.

Example of Structural Walls

1. Exterior - Concrete

2. Generic - Masonry

3. Exterior - Brick on Metal Stud

4. Exterior - Brick on CMU

Wall Properties Dialog Box


71/127

68

Wall Properties Dialog Box

You can modify the location line, base and top constraints, and structural

usage parameters using the Instance Properties dialog box.

Location Line

A location line represents a vertical plane in the wall. This parameter is

independent of the wall type and does not change if the wall type is changed.

You can specify the location line of a wall using any of the following options:

Wall Centerline

Core Centerline

Finish Face: Exterior

Finish Face: Interior

Core Face: Exterior

Core Face: Interior

Base and Top Constraints

The Base Constraint and Top Constraint parameters are used to define the

wall vertically in the model. When you specify the base and top constraint of a

wall, you connect the wall to specified levels.

After you specify the base constraint of a wall, you may also specify a value

for base offset. This sets the bottom of the wall elevation below the floor by a

certain distance to reach the foundation.

Structural Usage Parameters

The Structural Usage parameters determine the function of a structural wall

in a model. These parameters set apart structural walls from nonstructural or

partition walls. The Structural Usage parameters are categorized as

nonbearing, bearing, shear, and structural combined.


72/127

69

The value of the Structural Usage parameter controls whether the wall is

placed as a structural or a partition wall. By default, structural walls are

assigned as bearing and partition walls are assigned as nonbearing.

Nonbearing walls do not appear in structural views. You can change the

Structural Usage parameter any time.

Wall Options Bar

When you select the Structural Wall tool, the Options Bar displays wall

placement options. The following illustrations show the various options

available on the Options Bar.


73/127

70

Wall sections

To modify wall section from Wall Properties Dialog Box click edit type

As pervious you have two options

Rename or Duplicate

1-Rename

this option will modify the

current section to new section.

2-Duplicate

This option will make

duplicate from current section

and then change name and the

parameters to new section.

Click edit and modify the

thickness of wall to new

section.


74/127

71

Creating Floors

Floors are horizontal surfaces that support gravity loads and transfer these

loads to the supporting structure.

You add floor elements in a plan view using the Floor tool. When you select

the Floor tool, the sketch mode is activated and all the elements in the model

are halftoned and not accessible. In the sketch mode, you add sketch lines to

define the boundary of the floor. You can place sketch lines using the

Pick Walls, Pick Supports, or Line tool. You can create an opening in a floor by

editing the floor and sketching secondary loops inside the main floor outline.

You can also create an opening in a floor using the By Face, Shaft, and

Vertical tools on the Opening panel of the Modify tab. The openings that are

created by this method are hosted by floors, but these

openings remain independent.

Process of Adding a Floor Element:

To add a floor element to a project, you use the Floor tool on the Structure

panel of the Home tab.

Process: Adding a Floor Element

The following illustration shows the process of adding a floor element.


75/127

72

The following steps describe the process of adding a floor element.

1. Open the structural model in a plan or 3D view.

Open the structural model in a plan or 3D view to add a floor element.

2. Use the Floor tool.

Use the Floor tool to start placing a floor element.

3. Specify properties.

Specify properties of the new floor type by opening the Instance Properties

dialog box, followed by the Type Properties dialog box. Select Duplicate in the

Type Properties dialog box to create a new floor type, and then specify the

floor type properties.


76/127

73

4. Sketch the outline.

Sketch the outline of the floor type to place an opening. You can draw lines or

pick walls, supports, or lines.


77/127

74

5. Add openings in the floor sketch.

Add openings in the floor sketch using additional outlines. You can also use

the tools on the Opening panel of the Modify tab after the floor is completed.


78/127

75

Creating Shaft Openings in Floors

You can cut openings in the entire height of a building using the Shaft tool on

the Opening panel of the Modify tab. Using this tool, you can cut faces of

roofs, floors, and slab-on-grades simultaneously.If you move the shaft opening on one level, it moves on all levels. The

symbolic lines are visible on all levels too.

Procedure: Creating a Shaft Opening in a Floor

The following steps describe how to create a shaft opening in a floor.

1. Open a plan or a 3D view.2. Click Modify tab > Opening panel > Shaft.

3. Sketch a shaft opening by drawing lines or by picking walls.


79/127

76

5. Click Finish Opening.

6. Select the opening and click Element Properties to adjust the levels

that the opening cuts.

For Base Constraint, specify a level for the start point of the shaft.

For Top Constraint, specify a level for the end point of the shaft. The

shaft cuts through and is visible on all intermediate levels.

77

Creating Foundations

Foundations are model elements that are used to represent the physical

building foundation in a structural model. Foundations are typically modeled

as either deep foundations or shallow foundations, depending on the soil

conditions of the building site. Deep foundations consist of grade beams

spanning pile caps supported on piles. Shallow foundations consist of wall

footings, isolated column footings, and foundation slabs or mats.

Types of Foundations

The following table describes the different types of foundations.

Example of Foundations

Foundation with pile caps, a foundation

slab, and beams


81/127

78

Foundation with column footings, a

foundation slab, and wall foundations

Isolated Footing

Component families that are

placed beneath columns or

other structural elements where

loads are concentrated at a

point. These include isolated

column footings for shallow

foundations and piles and pile caps for deep foundations.

Place an Isolated Footing

1. In the Structure tab> Foundation panel, click (Isolated) to start

the Structural Foundation: Isolated command.

2. In the Type Selector, select a footing type.


82/127

79

3.In the drawing, click to place the individual footing as shown

in Figure

4.To add more than one footing at a time, in the Modify | Place

Isolated Foundation tab>Multiple panel, select (At Grids)

or (At Columns) and select the grids or columns.

5.Press or (Modify) to end the command.

An isolated footing attaches itself to the bottom of the

Component.

Instead of adding extra levels for foundations, you can place

foundation elements at the lowest floor level and then change the

Base Offsetparameter for the columns and walls to lower the footing

below the floor. The foundation elements move with the base of the

walls and columns.


83/127

80

Slab Foundation

this general option to create foundations , by this option you can make

isolated footing , combined footing and raft.

Place a Structural Slab

1. In the Structure tab>Foundation panel, click (Slab) to start the

Structural Foundation: Slab command.

2. In the Type Selector, select the slab type you want to use.

3. In the Modify | Create Floor Boundary tab>Draw panel, use the following

options to create a closed boundary:

Use the Draw tools, such as (Line) or (Pick Lines) when the

slab is not defined by walls or a structure and is free-floating.

Use (Pick Walls) when walls define the perimeter (Pick Supports)

and select structural walls or beams when the slab is supported by

beams.

In the Modify | Create Floor Boundary tab>Mode panel, click(Finish Edit Mode).


84/127

81

Adding Dimensions

The dimension tools available to you can be found on the Annotate menu,

in the Dimension tab

Aligned dimensions

The first dimension type that we are going to look at are Aligned Dimensions.

The key thing to note about Aligned Dimensions are that they can be placed

between 2 or more parallel references or 2 or more points- wall ends for

example. The dimensions in the image below are all Aligned Dimensions.

One important thing to note here is that when you select Aligned to start

dimensioning, the Options bar presents you with some important choices that

will aid you in creating your dimensions.


85/127

82

You will see above that you have a choice as to what Revit snaps to when

dimensioning. The Place Dimension drop down box contains Wall

centrelines, Wall faces, Centre of core and Faces of core. The second choice

you have when placing your dimensions are Pick.

At this point it is worth taking a moment to look at the differences between

these two options because this is something that you will use time and again.

If we leave Pick set at Individual References, you have the choice where to

dimension to, along a wall length- ie from the end of the wall to the start of

the first window opening


86/127

83

However, if you change Pick to Entire Walls, you can now just pick

anywhere on the wall and the entire wall is automatically dimensioned

Note that all the dimensions were added in one go, following a single click on

the wall. To tell Revit exactly what elements of the wall you wish to be

dimensioned, click on Options on the Options Bar (this is only available if

you have Pick set to Entire Walls.

You will see that you can dimension (automatically) to openings, intersecting

wall and intersecting grid lines. Used appropriately, this feature can save you

a vast amount of time. Imagine a long elevation with 14 windows and 3

doors- and being able to dimension all of it with a single click! Ok, thats

enough of Aligned Dimensions, lets move on.


87/127

84

Linear dimensions

Next on our list are Linear Dimensions. We use Linear Dimensions, when we

want the absolute distance (measured vertically or horizontally) between two

offset points. This is better explained with a diagram.

Angular dimensions

As you may expect, Angular Dimensions are used to measure the angle

between two reference points that share a common intersection. Quite simply

click on the first reference element (be it a line, wall, etc) and then on the

second one.


88/127

85

Radial dimensions

Radial dimensions are used for measuring the distance from an arc to its

centre point. In the case of Walls, you can measure either to the wallcentreline or the wall face. Pressing the tab key when defining your

dimension will toggle between wall face and wall centerline.

Arc Length dimensions

Radial dimensions are used for measuring the distance along an arc segment.

This could be a line or wall. Again the Tab key will toggle between

centrelines and faces, in the case of walls.


89/127

86

Baseline and Ordinate dimensions

Two other linear dimension types that are available to you (but not obviously

evident) are Baseline and Ordinate dimensions. These are basically two

different types of Running Dimensions. In order top use these, you will need

to first create the dimension types. This is really easy to do- just pick the

default Linear (or Aligned) dimension family and duplicate it (renaming it of

course). Once you have a copy of the family, you can go into its properties

and Edit Type.

You will notice that the first parameter in the list is Dimension String Type.

This is the parameter we are interested in. If you activate the drop-down

menu for this parameter- you will see that you have a choice of Continuous,

Baseline or Ordinate. Go ahead and change the parameter to Baseline.

This results in a dimension like this.


90/127


91/127

88

Here is a Spot Elevation in a section view, telling us the height at the top of

the wall.

And here is a Spot Elevation in a plan view. This time it is displaying the

bottom and top heights of a floor plate element.

Spot Coordinates dimensions

Spot Coordinates display the North / South and East / West coordinates of the

reference point it is placed at. It can also display the elevation at that height

too.


92/127

89

Spot Slope dimensions

Andfinally.. Spot Slope Dimensions! As you might well expect, these are

used for displaying the angle of slope on various surfaces and elements. Theycan be placed in section, elevation and plan views. Here is one being used on

a roof slope in a section view..

You have a choice of an arrow or a triangle for the symbol- we have obviously

chosen the triangle symbol in the above example.

And that concludes our introductory look at Dimensions in Revit. In other

articles we will go onto to look at how we can manipulate and customise the

look and operation of these various dimension types.


93/127

90

Adding TagsTags are annotations that display parametric information about the elements

with which they are associated. Tags use unique symbols to represent each

structural element. Unlike text, the values displayed in tags are updated

automatically when the structural model is updated. Tags are view specific,

can be placed with or without leaders, and have horizontal or vertical

orientation. Tags automatically adjust to the view scale and align with other

tags in the view. You can modify tags by changing their position in a view,

turning their leaders on or off, and changing their orientation. You can tag a

structural element with more than one tag if you have multiple tag types

loaded for that element.

Types of Tags

Structural Framing Tag :

Displays the Type Name property of a structural framing member. This tag

rotates with its associated element.

Structural Framing Tag-w-Studs-Camber:

Displays the Type Name, Number of Studs, and Camber Size properties of a

steel structural framing member. This tag rotates with its associated element.

Structural Column Tag :

Displays the Type Name property of a structural column member. This tag

orients to the view.

Structural Column Tag-45:

Displays the Type Name property of a structural column member at a 45-

degree angle to the column member. This tag orients to the view.


94/127

91

Tag Options:

You can place tags in a view using the tag options available in the Tag drop-

down on the Tag panel of the Annotate tab. The Tag drop-down provides

three options: By Category, Multi-Category, and Material.

The following table describes the various tag options.

By Category:

Automatically identifies the category of the object being tagged and adds

the appropriate tag.

Multi-Category

Uses shared parameters to add tags that work across categories.

Multicategory tags are custom objects.

MaterialDisplays a question mark when first placed. You need to specify a value for

the material parameter, which is then displayed in the tag.


95/127

92

Beam Annotations Dialog Box:

Using the Beam Annotations dialog box, you can place or remove structural

framing tags and spot elevation symbols on selected or all beams in a view.

To access the Beam Annotations dialog box, you use the Beam Annotationstool on the Tag panel of the Place Text tab. You can also specify the position

of framing tags or spot elevation symbols at the start, middle, or end of

beams.


96/127

93

Process of Adding Tags:You can add tags to the selected or all structural framing members in a view.

Process: Adding Tags

The following illustration shows the process of adding tags.

The following steps describe the process of adding tags.

Activate the Tag tool :

Activate the Tag tool on the Tag panel of the Annotate tab.

Note:You can use the Tag All tool on the Tag panel of the Annotation tab to

tag all elements of one type, such as columns in the current view.

Specify tag properties:Specify the tag properties such as tag orientation and leader length, on the

Options Bar.

Place tags:Place tag using reference lines to align the tag with the nearby tags and text.

You can change the tag orientation and add or remove a leader after tag

placement.


97/127

94

Views

Definition of Views

Views provide a way of visualizing and working on a building model. You use

views to display a model from different directions and reference points that

help you build the model. In addition, you use views to generate plans,

elevations, sections, details, and schedules that are used to assemble

construction documentation. When you start a project, certain views are

created by default based on the project template that you select. You can edit

the properties of these views and create new views, as required. You can also

duplicate existing plan and 3D views to create new views. You can navigate

within a view using the mouse wheel, Steering Wheels, or the view cube, and

switch between views in the middle of an activity. For example, you can select

a floor in 3D view and edit it in plan view. However, only one view can be

active at any given time.

Options for Duplicating Views

By duplicating a view, you can display the same portion of the structural

model in multiple views with different view settings, if required.

The following table describes the three options that you can use to duplicate

views.


98/127

95

Duplicate:

This option creates a view that is a copy of the original view. A duplicate view

displays model elements but not annotation elements from the original view.

For example, you can use this option to create a duplicate foundation plan

that displays a referenced architectural plan and is used for coordination

purposes. The duplicate plan is independent of the original foundation plan.

Duplicate with Detailing:

This option creates a view that inherits all details of the original view. A

duplicate with detailing view displays both model and annotation elements

from the original view. For example, you can use this option to create an

overall foundation plan that includes the detailing you added to the original

foundation plan. The overall plan is independent of the original foundation

plan. Any additional annotation you add is displayed only in the view to which

it is added.

Duplicate as a Dependent:

This option creates a dependent view that inherits view properties and view-

specific elements from the original view, known as the parent view. A

dependent view is used to display only a specific area of the view. You can

insert matchlines to indicate where the view is split and view references to

link views. Annotation added to the dependent view is displayed in the parent

view and vice versa. This option helps to create views that show portions of a

plan when the entire plan is too large to fit on a drawing sheet.


99/127

96

The following illustrations show an original view and its duplicate

copies created by using the options for duplicating views.

Original view with annotation

Overview of Visibility and

Graphic Display

Most overrides for visibility and graphic display are made in the

Visibility/Graphics dialog. The exception is for individual element overrides;

these are made in the View-Specific Element Graphics dialog. From the

Visibility/Graphics dialog, you can view overrides that have already been

applied to a category. If the graphic display of a category has beenoverridden, the cell displays a preview of the graphic. If no overrides have

been made to a category, the cell is blank, and the element displays as

specified in the Object Styles dialog. In the following image, the doors

category has overrides for projection/surface lines and for cut pattern.


102/127

99

Move and Copy

Revit Structure contains editing tools and temporary dimensions that enable

you to edit elements. Additional modifying tools can be used with individual

elements or any selection of elements. They are found in the

Modify tab>Modify panel, and in contextual tabs.

The process of copying an element is identical to moving an element,

except that by default, a copy is moved instead of the original object.

Move or Copy Elements

1. Select the element(s) that you want to move.

2. In the Modify panel, click (Move) or type MV or click (Copy)

or type CO. A boundary box displays around the selected element(s).

3.

Select a base point on or near the element.

4. Select a second point.

5. Use alignment lines and temporary dimensions to help place

the element(s). Snaps are also helpful for placement, or type the

distance by keyboard .

6.

The element(s) remain highlighted, enabling you to start

another command, or you can press to end the command.


103/127

100

Move/Copy Options

The Move and Copy commands have several options that display in the

Options Bar.

Constrain: Only moves the element by 0, 90, 180, or 270 degrees. If

the element is at an angle (i.e., an angled wall), Constrain also

enables it to move parallel to its current location.

Disjoin: Moves the element independent of any other elements to

which it is attached or related. For example, a wall joined to other

walls at each end can be moved without extending the joined walls

using Disjoin.

Copy: Creates a copy of the original element. This makes the Multiple

option available, which permits multiple copies. With the exception of

the Multiple option, the options revert to their defaults each time you

restart the command.

Summary

The use of a Revit building information model gives structural

firms an integrated modeling environment for analysis and

documentation so that the structuraldesign and documentation

are coordinated, consistent, and complete. Leveraging existing

architectural digital design information and sharing the structural

building information model with architects and engineers further

coordinates the buildingdesign and documentation a winning

combination for all parties involved in the design, construction

and operation of a building.

The best example emerging today is the use of three-dimensional,

intelligent design information, commonly referred to as Building
