Tekla Structures 16.0 Release Notes

1 Tekla Structures 16.0Release Notes

Tekla Structures version 16.0 is a main version and contains many new features and fixes.

Compatibility Tekla Structures 16.0 is compatible with all previous versions. You can open and work withexisting models using Tekla Structures 16.0. Note the following issues:

To avoid conversion problems, always open a model created with an older version of TeklaStructures as a single-user model first.

Updating drawings created with an older version of Tekla Structures in Tekla Structures16.0 may cause problems. We recommend that you complete any drawings you havestarted using your current version or recreate the drawings using Tekla Structures 16.0.

We recommend that you always check that custom components created in older versionswork correctly in the new version of Tekla Structures.

When you open custom components made with an older version of Tekla Structures in theCustom component editor, and the new version contains improvements requiring update,Tekla Structures asks whether you want to update the component. If you do not update thecomponent, it works in the same manner as in the version where it was originally made,

but you do not gain the benefits of the improvements.

If you choose to update the component, you need to check and sometimes even recreatedimensions depending on the improvements. When you delete a dimension and create anew one (even with the same name), also the equations containing the dimension need to

be edited, because the dependency created by the equation is lost when a dimension isdeleted. You can recreate the dimensions and edit the equations easily in the Customcomponent editor.

We suggest that you complete any models you have started using your current version.

Installing Tekla Structures setup creates a new subfolder for Tekla Structures 16.0.

You need Windows Administrator rights to install Tekla Structures 16.0. This ensures that allWindows system folder*.dll files are updated.

Once you save a model in Tekla Structures 16.0, you cannot open it inprevious versions of Tekla Structures.

Changes in the installation of Tekla Structures

The following changes have been included in the Tekla Structures 16.0 installation:

When you install Tekla Structures for the first time on a computer, it is installed in theWindows Program Files folder by default. If you have a previous version of TeklaStructures installed, the default location for the installation is the same as before.

When Tekla Structures is installed in the Program Files folder, the location of theenvironment folders is:

..\ProgramData\Tekla Structures\16.0\(Windows Vista)

..\Documents and Settings\All Users\ApplicationData\Tekla Structures(Windows XP)

When Tekla Structures is installed in the Program Files folder, the location of theteklastructures.ini file is ..\Program Files\TeklaStructures\16.0\nt\bin.

When Tekla Structures is installed in the Program Files folder, the location of theuser.ini file is:

..\Users\\AppData\Local\TeklaStructures\\UserSettings\(Windows Vista)

..\Documents and Settings\\ApplicationData\Tekla Structures\\UserSettings\(Windows XP)

The Default environment is no longer installed by default.

The changes are related to Windows 7 certification.

Files and Folders

Improvements in FLEXnet licensingTekla StructuresLicense Server

Tekla Structures License Server 1.14 is published with Tekla Structures 16.0.

Tekla StructuresLicenseAdministrationTool

Tekla Structures License Administration Tool 1.14 is published with Tekla Structures 16.0.

The license server is now automatically notified when you activate, deactivate, or repairlicenses. Previously, you had to use the ReRead License File functionality in LMTOOLSto manually notify the license server about the license changes.

You can enable the automatic notification functionality when Tekla Structures LicenseAdministration Tool is started for the first time. You are asked whether you want toautomatically notify the license server about the license changes. To enable the automaticnotification functionality, selectYes.

If you later want to modify the notification settings, go to Actions > Notify Server.

You can now check to which computer a license is borrowed, and the expiry date of theborrowed license. The Activated Licenses table has a new column Details that you canuse for checking the license borrow information.

Do no use the automatic notification functionality if you are using someother FLEXnet license and license server administration tool, such asFLEXnet Manager.


18/130



If license borrow information is available, a button is displayed in the Details

column. The button is always displayed when the Borrowed column indicatesthat licenses have been borrowed.

If the Details column is empty, there is no borrow information available for that license in

question.

The button is also displayed when a borrowed licence has expired. This means

that a license has been borrowed but it has not been returned by the expiry date. When theexpired license is returned, the information is removed from the license details list.

Also if you return a borrowed license before its expiry date, the license information isremoved from the license details list.

See an example ofLicense Details below:

Borrowed License Expiry Date is the expiry date of the borrowed license.

Host Machine is the name of the computer to which the license has been borrowed.

A new colum Order ID has been added in the Entitled Licenses and Activated Licensestables. The order ID is the same as in the EntitlementCertificate.htmlfile. Theorder ID helps to identify which licenses are related to each other and which license needsto be returned before a new license can be activated.

Tekla StructuresLicense BorrowTool

Tekla Structures License Borrow Tool 1.14 is published with Tekla Structures 16.0.

2.3 Modeling

Improvements in Mini Toolbar

The following improvements have been made to the Mini Toolbarin Tekla Structures 16.0:

Improvedposition selection

You can now control the position of objects more easily using a specific selection wheel inthe Mini Toolbar. When you use the selection wheel, the object moves in the modelaccordingly. The position is set according to the global coordinate system.


20/130



Otherimprovements

You can now use the Mini Toolbaralso for grids and views.

The commands on the Mini Toolbarfor welds are now grouped in a more intuitive way.

For moreinformation

Customizing Mini Toolbar

Improvements in numberingTekla Structures 16.0 includes the following improvements in numbering:

Numberingselected series

You can number different areas of the model separately by using the new Number Series ofSelected Objects command.

The command numbers all parts and assemblies that have same numbering series settings. The

series is determined by the prefix and start number of the selected part. For example:

The Number Series of Selected Objects command allows you to:

Selectively number the same types of parts but in different phases or cycles of detailing atdifferent times

Part orientation

Position selection dial

Rotation angle knob

Angle

Plane offset

Depth offset


21/130



Number different materials (such as concrete and steel), which are usually at differentdetailing and release cycles but in the same Tekla Structures model, with differentnumbering settings and at different times

Tekla Structures also uses this functionality when you open or create a drawing where one ormore parts or assemblies require numbering. If you modify a part that has been used in manydifferent assemblies, all the related assemblies will be numbered.

The new functionality saves you a lot of time especially when working on a large model, as youno longer need to number the entire model at once. Before you start numbering, we recommendthat you plan the numbering series carefully, and split the model into smaller numbering series,for example by area or phase.

Diagnosing andrepairingnumbering

The Tools > Diagnose & Repair Model menu now contains two new commands for diagnosingand repairing numbering.

Diagnose & Repair Numbering: All numbers all objects, including those that have notbeen modified.

Diagnose & Repair Numbering: Series of Selected Objects numbers all parts thatbelong to the selected numbering series.

The basic functionality is the same for both of the commands: to find and correct numberingerrors in the model. The operation can be performed for all objects or series of objects. For

example, if you have two identical parts with a different position number, these commandsassign both parts the smaller one of those two values. The same applies to assemblies. If youare working on a multi-user model and have not used the Synchronize with master model(save-numbering-save) option, you should use these commands to diagnose and repair thenumbering of the model.

Numbering

concrete parts

Concrete parts now get the numbering settings from the cast unit numbering series. This

enables you to number individual concrete cast unit series, without having to number the entiremodel at once.

When you create new concrete parts, they are automatically numbered according to the castunit numbering settings. For example, if the cast unit prefix is C and the start number is 1,concrete parts will get the part prefix Concrete_C-1.

This applies also to concrete components whose part position prefix is Concrete and startnumber is 1.

The new commands replace the old Number All Objects (Fullnumbering) command available in previous versions of TeklaStructures.

This functionality is not compatible with models created using aprevious version of Tekla Structures.

For moreinformation

Numbering the Model

Clash Check Manager

Tekla Structures 16.0 contains a new clash checking functionality, which helps you manage

clash results better. Clash Check Managerprovides the following improvements:

Clashes are automatically classified according to their type.The available clash types are: Inside, Exact match, Cut through, Clash, and Complex clash.

You can sort your clash check results.

You can zoom to clashing objects in the model.

You can change the status of the clashes.

After removing or modifying objects, you can re-run clash check to see if the clash stillexists.

You can save clash check sessions and view them again later on.

Improvements in snapping

Tekla Structures 16.0 includes the following improvements in snapping:

Snapping to aline The new Snap to line snap switch allows you to snap to another line in the model.

This can be useful when creating objects that line up with an existing object or a grid line.

You can use this snap switch with any command that asks you to pick two or more points.Tekla Structures automatically picks both ends of the line. The yellow arrow symbolindicates the direction of the points. To switch direction, move the mouse pointer closer to

the opposite end of the line.

Snapping to partextension lines

You can now snap to part extension lines in 3D space. If the part is rotated, also theextension lines are rotated.

The mouse pointer tries to stay on the line when moving along the part extension line. Atfirst you must move the pointer close to the object to find the extension line, but when theline is found you can move the pointer further away while keeping the snap.

If you use the snap switch with a command that requires only one pointto be picked, for example when creating a column, only the start point ofthe line is used to position the part.


24/130



Snapping in anorthogonaldirection

When picking multiple points, for example when you create a polybeam or a contour plate,you can snap in orthogonal directions relative to the two previously picked points. This isuseful, for example, when you want to create a rectangular slab that is on the view plane

but not along the x and y axes.

The color of the line and angle symbol changes to indicate that the snap is orthogonal tothe previous points and not the work plane:

Zooming to selected parts

As the models are getting larger and more complex, it might be difficult to see which objectsare currently selected. In Tekla Structures 16.0, you can zoom the active view so that theselected objects are shown in the center of the view. This can be useful, for example, when youare viewing the clash check results or working with Task Manager and you are not sure which

part is currently selected.To zoom to selected parts, do one of the following:

ClickView > Zoom > Zoom Selected.

Right-click and select Zoom > Zoom Selected from the pop-up menu.

Automatic view rotat ion center

In Tekla Structures 16.0, you have two alternative ways of setting the center of rotation.

The conventional way is to press V and then pick a position in the view. To rotate themodel around this view point, hold down Ctrl and click and drag with the middle mouse

button.

Alternatively, you can use the new Automatic Rotation Centerfunctionality available inTools > Options. IfAutomatic Rotation Centeris switched on, when you hold down Ctrland click and drag with the middle mouse button, the rotation center is automatically set atthe location you clicked.

When you are using the conventional rotation method, you cantemporarily activate Automatic Rotation Centerby holding down Ctrl+ Shift while you click and drag with the middle mouse button.

Reinforcement meshes with multip le bar diametersIn Tekla Structures 16.0 the reinforcement mesh detailing has been improved. It is now possibleto define multiple diameters for the bars in polygon, rectangle and bent reinforcement meshes.The diameters can be defined separately in both the longitudinal and the cross direction.Previously it was possible to define only one diameter for the bars in each direction.


30/130



Multiple diameters enable the creation of diameter patterns. The pattern is repeated along themesh, if needed. The maximum bar diameter in the pattern is used to calculate the mesh

position depending on the cover thickness and offsets.

For example, entering 40 2*20 as the diameters in the longitudinal and 8 40 2*20 in thecross direction results in the following patterns.

Pattern inlongitudinal

direction

Pattern in crossdirection

For moreinformation

Meshes

Improvements in bent meshes

The first longitudinal bar can now be placed in a curved part of the cross bars. Previouslythe longitudinal bar needed to be placed in the first straight segment.

It is now possible to set the start and the end offset greater than the length of the firstsegment. Reinforcing bars are resized along the defined position.


31/130



If the start or the end offset type is set to Leg length, only the straight part of thereinforcing bars is resized.

If the bent mesh geometry (combination of handles, bending radius and the maximum bardiameter) is not correct, the mesh is not created.

When you modify a bent mesh by changing the dialog box values and the changes wouldresult in a broken mesh with incorrect geometry, the mesh is not modified.

When you modify a bent mesh by moving the handles, and the changes result in a brokenmesh with incorrect geometry, a single red line is drawn between the handles. The red linecan be selected and modified to correct the mesh geometry.

Improvements in filtering reinforcements

You can now filter reinforcing bars by their length. This is useful, for example, when checkingthe model for errors or when creating a report of reinforcing bars of a specific length.

For example, to check if the model contains reinforcing bars whose length exceeds 12 metres,you can filter out all reinforcing bars that are less than 12 metres long.

For moreinformation

Filtering objects

Improvements in reinforcing bar hooks

You can define reinforcing bar hooks Angle, Radius and Length. ForAngle you can enter avalue between 180 and +180 degrees. However, you cannot enter a negative value forRadius

orLength anymore. The Radius and Length fields do not accept negative values.

Improvements in conceptual reinforcements

Conceptual reinforcements can be created with the Steel Detailing and Engineeringconfigurations. Conceptual reinforcements look similar to detailed reinforcements but do notinclude the option to assign control numbers (Steel Detailing) or perform numbering(Engineering).

Conceptual reinforcements that are created using components (such as Beam reinforcement(63)) can now be converted to detailed reinforcements only in configurations that allowreinforcement detailing (Full, Precast Concrete Detailing and Reinforced Concrete Detailing).

Previously when you modified a part which the reinforcement component belonged to, thereinforcement was converted to a detailed reinforcement even though the reinforcement wasoriginally created in Steel Detailing or Engineering configuration and should therefore beconceptual.

Improvements in reinforcing bar bending type recognition

In Tekla Structures 16.0 the reinforcing bar bending type recognition has been improved.

Previously, you had to define an angle for some of the bending shapes to enable the correctbending type recognition. The angle was of an exact value, and there was no tolerance value forit.

With BendingAngleToleranceoption in the rebar_config.inp file you can nowset a tolerance value for the angle. Angles which differ from the set tolerance value less thanthe tolerance are recognized and lead to a correct bending shape.

Improved object visibili ty handling in Model Organizer

You can now easily handle the visibility of objects in the model by right-clicking a category inModel Organizerand selecting one of the following:

Hide - hides all objects that belong to the selected category.

Show Only Selected - shows only the objects that belong to the selected category.

Redraw View - shows all objects.

2.4 Drawings

Applying drawing object level sett ings on drawing and view level

The new drawing properties dialog boxes introduce a new option for controlling the drawingobject settings directly on the drawing and view level. Now setting up special representation forobjects in drawings or views is easier than ever. Simply set up a drawing or view filter thatselects the objects you want a special representation for, then create and save the object

property settings to be used for the objects specified by the filter, and then combine these twointo object level settings. For example, you may want to define that all columns in a drawing ordrawing view are shown in a specific color.You also have the option of turning the object levelsettings on or off for the drawings or views you choose.


34/130



Previously, you could do the same by using drawing classifiers, which had no settings to adjuston the user interface, and you had to manually define combinations of drawing or view

properties, filters, drawing object setting files and naming conventions to achieve the desiredresult.

The drawing object settings that you apply on the drawing or view level drawing propertiesdialog box override all the other drawing object settings defined in the drawing properties

dialog boxes. Object level settings defined on the drawing level are inherited to the view levelsettings if there are no object level settings defined on view level. If you define view levelobject settings, they override the drawing level settings.

Before you can apply drawing object level settings, first create and save the necessary drawingor view filters and drawing object property files.

Creating andapplying objectlevel settings ondrawing level

To create and apply the drawing object level settings on drawing level:

1. Click Drawings& Reports > Drawing Settings and select the type of the drawing.

New filters in drawings

Now the dialog boxes for filters are identical in the model and in the drawings. The new dialogboxes allow you to make more complex filters in the drawings.

Furthermore, the Filterbutton is now available for all drawing types using filters (Drawings &Reports > Drawing Settings > Assembly/Cast Unit/General Arrangement Drawing ).


39/130



New Mini Toolbar for modifying objects in drawings

Also the Drawing Editor now has a Mini Toolbar,which allows you to quickly modify the mostcommon properties of the objects in drawings.

Below is the Mini Toolbarfor dimensions.

New symbol file browser

The new symbol browser makes changing the symbol file in use considerably easier thanbefore. When you want to select a new symbol file, just click the Select... button in the SymbolProperties orMark Content - Symbol dialog box and select a new file.

Symbol files are searched from folders listed in DXK_SYMBOLPATH, which is defined ininitialization file teklastructures.ini.The order of folders in DXK_SYMBOLPATH doesmatter: If there are duplicate file names, the first one found is used.

New automatic view shortening symbols

Tekla Structures can now show more clearly where the parts have been shortened in views withthe new automatic view shortening symbols.

To show the shortening symbols in drawings, set the advanced options

XS_DRAW_VERTICAL_VIEW_SHORTENING_SYMBOLS_TO_PARTS andXS_DRAW_HORIZONTAL_VIEW_SHORTENING_SYMBOLS_TO_PARTS to TRUE through Tools >Options > Advanced Options... > Drawing Properties.

You can control the appearance of the view shortening symbols using the following advancedoptions:

XS_SHORTENING_SYMBOL_COLOR controls the color. Enter an integer value. Default is thesame as the part color.

XS_SHORTENING_SYMBOL_LINE_TYPE controls the line type. Enter an integer value.Default is a solid line.

XS_SHORTENING_SYMBOL_WITH_ZIGZAG controls the line shape. If you do not want touse zigzag, set this advanced option to FALSE. TRUE is the default.

Below is an example of how the symbol is displayed.


40/130



Limitations View shortening symbols are not shown in general arrangement drawings.


41/130



Improvements in dimensions

Rotating

You can now rotate certain dimension tags 90 degrees. This is useful when absolutedimensions are used, for example. See examples below.

To set the rotation in a drawing, go to Dimension Properties > Marks and click the ...button next to the Tag that you want to rotate. The choices are Parallel to dimension line(no rotation, default) and Perpendicular to dimension line. Each tag has independentrotation setting, so you can rotate some tags and keep others unrotated.

This functionality is available only for left upper, left lower, right upper and right lowerdimension tags. For middle dimension tag and prefix and postfix dimension marks,rotation is not available.


42/130



Formatting The dimension tags now have the same formatting options available as other marks. Youcan set font and frame settings separately for any tag element. By default, the formattingfollows the dimension settings, but you can now use special fonts and frames to emphasizecertain elements.

Dual dimensiontags

It is now possible to create dual dimension tags automatically in all types of drawings.

You can set the dual dimension tags in Tools > Options > Options... > Drawing dimensions.

You can select separately the drawing types for which to create the dual dimension. WhenTekla Structures creates the drawing, it adds in the lower dimension tag in the selected unit andformat, and puts the text DIMENSION in the middle dimension tag in the DimensionProperties dialog box.

To add dual dimensions manually:

Dual dimensions can be shown only in relative and US absolutedimensions, but not in absolute dimensions.


43/130



1. Go to Tools > Options > Options... > Drawing dimensions > Dimensions in tags, set theunit, format and precision, and activate the dual dimensions for the drawing types youwant.

2. Click OK.

3. Double-click a dimension in your drawing.

4. Add text DIMENSION to any dimension tag.

5. If you do not want to show dual dimensions in some dimensions, you can delete the textDIMENSIONmanually from the tag.

Below is an example of dual dimensions using unit mm and format ###.


44/130



Improvement in moving drawing objects: objects visible while dragging

Moving objects is one of the most common tasks in drawings. Now you are able to see duringobject dragging what the end result will be. There is a cross in the middle of the cursorindicating the object that you are dragging.The magenta lines in the cursor make it easier to

place the object in line with other objects. This will significantly reduce unnecessary editing.

Improvements in Master Drawing Catalog

In Tekla Structures 16.0, the Master Drawing Catalog has been improved further:

The master drawing preview image window size is now larger than before. Also, if youresize the preview image, Tekla Structures remembers the new size next time you open the

preview image.

In Edit Rules and Define Rules dialog boxes, a letter has been added after the masterdrawing name to indicate the type of the master drawing. (S) indicates saved settings, (T)cloning templates, and (R) rule sets. This makes it easier to select the correct masterdrawing if you have two master drawings of different type but with the same name, forexample.

You can now create drawings for all parts. First select a master drawing from the catalog,then click the arrow at the end of the Create drawings button, and clickCreate drawingsfor all parts.


45/130



New shortcuts:

Select all: Ctrl + A

Create drawings for all parts: Alt + A

Create drawings: Alt + C

The Master Drawing Catalog now remembers search strings. When you start typing a

string, it suggests previous strings starting with the same characters.

Improvements in associativity

Drawing views Now the size and location of a drawing view can be associated also to a portion of a modelpart in cases where the parts are not completely inside the view. Previously, the viewboundary was updated using only the parts that were completely inside the view. Views arenow associative even though the view does not contain any part completely. This applies toall view types, but is best shown in detail views, as they are often used for showing a detailof a part.

In the following example, the drawing is cloned from template. Cloned drawing has the

same view showing the same detail in a different place and size.

3D views in assembly and cast unit drawings are now associative. The view size anddrawing annotations are updated correctly. This applies also to cloned drawings.


46/130



Drawings views that use Model coordinate systems are updated and cloned correctly.

Refreshingassociativity

Often improvements in cloning and associativity require that the associative rules have tobe recreated. Previously this meant that you had to recreate the whole drawing. Now youcan recreate associative rules for a drawing using the new Refresh Associativitycommand, instead of recreating the whole drawing. This command is very useful if you,for example, have a template drawing you have created using an older Tekla Structuresversion and want to utilize the better associativity of a newer Tekla Structures version.

You may want to add the Refresh Associativity command in the Usermenu throughTools > Customize.

Dimensiongrouping Now the number of objects in the dimension grouping tag is updated correctly.

You can now define that Tekla Structures updates dimension grouping automatically byselecting the option Update grouping when model changes on the Dimension groupingtab page (Drawing Properties > Dimensioning).

Improvements in arcs in drawings

The following improvements have been included in Tekla Structures 16.0 for the representationand export of arcs in drawings:

Curved and circular lines in drawings are now displayed so that the dashed lines are clearand continuous.

Curved and circular lines are now exported to DWG as arcs, not as segments.

Ensure that the Snap to end points switch is enabled when snapping toarcs.

This functionality affects only parts, not reinforcing bars.


47/130



Improvements in welds

Dialog boxchanges

The Weld Properties dialog box in drawings has been renewed in Tekla Structures 16.0. Thenew dialog box has more options, and most of the properties can now be defined separately forAbove line and Below line.

The changes include:

New weld types

New finish types:

Renewed terminology: stitch welds are now called intermittent welds. The option isavailable for both Above line and Below line.

Dialog contents have been moved around a bit. For example, Prefix is moved to the top,and Effective throat and Root opening are moved from the Otherarea to Above line andBelow line.

Steep-flanked single-V butt weld

Steep-flanked single-bevel butt weld

Flush finished weld

48/130



Showing rootopenings in weldmarks

You can now select whether zero root openings are shown in weld marks. Use the newadvanced option XS_DRAW_ROOT_OPENING_EVEN_WHEN_ZERO to control the root openinginformation in weld marks.

The following example shows the result when the Root opening option is set to 0 in the WeldMark Properties dialog box and XS_DRAW_ROOT_OPENING_EVEN_WHEN_ZERO is set to TRUE.

Improvements in merging parts in cast unit drawings

If you have adjacent parts in a cast unit, and the gap between these parts is less than thetolerance you specify using the new advanced optionXS_DRAWING_SOLID_MERGE_TOLERANCE in Tools > Options > Advanced Options >Drawing View, Tekla Structures merges the parts in the cast unit drawing.

Tekla Structures removes hidden lines as follows:

Edge segments are removed when necessary.

Whole edges that get hidden during merging are removed.

New edges are added in correct locations replacing the removed edges.

The following example shows the result of merging parts.


49/130



In the following example, unnecessary segments of curved parts that are one above another areremoved.


50/130



Improvement in details: more characters allowed in detail name

Now you can enter a maximum of nine (9) characters in the detail name field. Previously, youcould enter only two characters.


51/130



Improvement in single-part drawing views in assembly drawings

Tekla Structures16.0 has a new useful feature for anyone using Include single parts > Single-part attributes option (Assembly Drawing Properties > Layout > Other). With the newadvanced option XS_USE_EXISTING_SINGLE_PART_DRAWINGS_IN_ASSEMBLY_DRAWINGSyou can specify whether to create new views or use views from existing single-part drawings inassembly drawings. If you have lots of similar parts in lots of different assembly drawings, youcan create single-part drawings of these parts and edit them so that they include everything thatyou need. When a single-part view of the part is included in an assembly drawing, it is

automatically copied from the original single-part drawing on the Drawing List, and all yourediting comes in automatically. The included views are scaled according to the layout settingsof the assembly drawing.

When you set the advanced optionXS_USE_EXISTING_SINGLE_PART_DRAWINGS_IN_ASSEMBLY_DRAWINGS to TRUE inSingle-Part View in Assembly Drawing, the existing single-part drawing views will be used inassembly drawings. When set to FALSE, or if there is no existing view for a given part, a newview will be created according to the Include single parts setting. The default value is FALSE.

See also Including single-part views in assembly drawings

Improvement in intelligent update: adding dimensions for new parts

With the new advanced option XS_INTELLIGENT_UPDATE_ADD_DIMENSIONS in Tools >Options > Advanced Options... > Drawing Properties you can now define whether to adddimensions for new parts when updating intelligent drawings. When this advanced option is setto TRUE, Tekla Structures creates dimensions for new parts at drawing update. The defaultvalue is TRUE.

Improvements in printing and exporting drawing view frames

You can now include drawing view frames in printed and exported drawings. To do this:

1. Click Tools > Options > Advanced Options.

2. Select Printing.


52/130



3. Set XS_PLOT_VIEW_FRAMES to TRUE. FALSE is the default value.

Preventing drawing view update according to grid planes

Typically you may want the drawing views to follow a grid line. Then, for example, your

Section on grid Cdrawing view would be up to date and still on grid line C even afterthe move. You can now prevent the updating of drawing views according to grid planes ingeneral arrangement drawings. This can be helpful if the general arrangement drawings areupdated incorrectly after you have modified the grid in the model. To prevent the update, setthe advanced option XS_INTELLIGENCE_DO_NOT_ASSOCIATE_VIEWS_TO_GRIDS to TRUEin Tools > Options > Advanced Options... > Drawing View. FALSE is the default value.

Checking view frames after manual editing

The frames of drawing views were sometimes modified if you edited the drawing manually.You can now use a new advanced option XS_DRAWING_CHECK_VIEW_FRAME_AFTER_EDIT in

Tools > Options > Advanced Options... > Drawing View to control the way the view framesare updated after you have edited the view contents manually. Use one of the following values:

TRUE: After the view content has been edited manually, the offsets are stored for the viewframe so that the size of the view frame is maintained during drawing update whenever

possible. For example, if there is empty space inside the view frame after deleting a mark,the same empty space remains in the view also during drawing update. This is the defaultvalue.

FALSE: The frame size of drawing views is checked only during drawing update. Forexample, if there is empty space inside view frame after deleting a mark, the frame size ismade smaller when drawing is updated after model change.

UPDATE : The frame will be adjusted immediately after you have edited the contentmanually. For example, if there is empty space inside view frame after deleting a mark, the

frame size is immediately decreased.

Removing right-hand angle dimensions from cloned drawings

You can now remove right-hand angle dimensions from cloned drawings by setting the newadvanced option XS_INTELLIGENCE_DELETE_RIGHT_ANGLE_DIMENSIONS to TRUE inTools > Options > Advanced Options... > Drawing Properties. Now also zero dimensions areremoved from cloned drawings. Note, that if the angle dimension was already 90, 180 or 270degrees before the update, the dimension is not removed.

Maximizing drawings when opened

Tekla Structures now contains a new advanced option, which you can use to maximizedrawings when you open them. To do this:

1. Click Tools > Options > Advanced Options.

2. Select Drawing View.

3. Set the advanced option XS_OPEN_DRAWINGS_MAXIMIZED to TRUE. FALSE is thedefault value.


53/130



Preventing recreation of drawings when a setting name changes

You can now set the new advanced optionXS_RECREATE_DRAWING_IF_SETTING_NAME_CHANGES in Tools > Options > AdvancedOptions... > Drawing Properties to FALSE to prevent Tekla Structures from recreating adrawing if only a setting name changes. The default is TRUE. Before, modifying any of the

drawing title fields or name for several drawings originally done with different settingsrecreated some of the drawings.

New tools for finalizing and editing drawings

Tekla Structures 16.0 includes new tools that you can use when finalizing and editing drawings.You can, for example, align drawing objects, create fillets and chamfers, copy with offsets, andcreate moment connection symbols.

To access the drawing tools, clickTools > Macros... and select Drawing tools from the list.

Product identifier in Tekla Structures drawings

In recent years there has been some confusion between the product names of Tekla Structures,old Xsteel and other detailing systems. Xsteel was the original 3D steel modeling and detailingsoftware developed and supplied by Tekla. It was replaced in 2004 with the launch of TeklaStructures - the 3D BIM solution for all materials and phases of construction design.

To make it clear with which software a project has been modeled and reinforce the TeklaStructures brand, we have added a Tekla Structures product identifier to the side of everydrawing. The product identifier will help promote the image of our customers' companies asforward thinking companies that use the latest and most advanced technologies and techniques.

If you need to change the position of the product identifier or turn it off, use the advancedoption XS_PRODUCT_IDENTIFIER in Tools > Options > Advanced Options... > DrawingView. Allowed values are DX and DY offset (for example, 0.50), FALSE, and TRUE.


54/130



2.5 Templates and Reports

New content type HISTORY

You can now use the new content type HISTORY to retrieve history information of the model.You can use this content type with PART, REBAR, CONNECTION and DRAWING rows.

The following template attributes can be used with this content type:

TYPE: the type of the historical action, for example update or numbering.

USER: the user who made the change.

TIME: the time the change was made.

COMMENT: the comment which was entered upon clicking Save.

REVISION_CODE: the revision code which was entered upon clicking Save.

2.6 Import and Export

Improvements in IFC import and export

The following improvements have been included in IFC import and export in Tekla Structures16.0:


55/130



You can now export assembly definitions, bolt sets (including a bolt with required washersand nuts) and reinforcing bars to an IFC model. To do this, selectYes in Assemblies,Bolts and Reinforcing bars lists in the IFC Export dialog box.

IFC export now supports type objects.

IFC export now supports quantity entities (IfcQuantityArea, IfcQuantityLength,IfcQuantityVolume, IfcQuantityWeight).

Importing and exporting IFC files is now faster. Also handling of large files has beenimproved.

For moreinformation

IFC export

Converting IFC objects in to native Tekla Structures objects

You can now convert the linear objects in an IFC reference model into native Tekla Structuresobjects by using a macro called IFCObjectConverter. You can also create reports to showthe converted objects, check their material and profile, and view their mapping files.

Using the macro enhances the workflow and saves time: you can use the structural objects thathave already been modeled by the architect, for example.

Improvements in Unitechnik export (79)

The Unitechnik export (79) component enables you to transfer model data to factoryautomation and ERP systems efficiently. You now have more control and flexibility in theexport, as the following improvements have been included in Unitechnik export (79) in TeklaStructures 16.0:

New options onthe Main tab

You can define how the cast units are exported on the Main tab:

By CU id: each cast unit has its own output file.

By CU pos: identical cast units share an output file. There is a new option in the Export assemblies list:

You can define the export code in the Def export code box.

You can define how to export embedded parts that are outside the concrete element:

Exports only the bounding box around themain part of the embedded block orembedded assembly.

New options onthe Unitechnikconfiguration tab

You can specify the folder where the file is exported in Directory path box. You have two new options for file names:

Proj_name.Cast_unit_pos.ID_user_extension

Proj_number.Cast_unit_pos.ID_user_extension

With these options, the 10-character long ID number will be included in the file name.

New options onthe TSconfiguration tab

You have more options to list classes, which helps to export the embeds in correct blocks. Usethe Electric tubes classes, Opening embed classes and Opening cutout classes boxes forthese purposes.

New tab Lineattributes

Sometimes line attribute values that are exported in the Unitechnik files are not suitable for thesituation in hand. For example, to preserve lightness in the model, you might have fewer

chamfers in the model than there will be in the actual structure. For this reason, you might wantto override some line attributes in the export so that the model stays light, but the exportedUnitechnik files are correct. You can do this by using the options on the Line attributes tab.

New options ontheReinforcementtab

You can export bent reinforcing bars by selectingYes in the Bent rebars export list.

You can define the Braced girder type.

New options onthe Dataspecification tab

The different options for data specification are now organized more clearly under the blocksthey relate to (HEADER, SLABDATE and MOUNTPART).

Improvements in drawing export

When you export drawings, the editable lines in drawings are mapped, and may have adifferent appearance depending on the software you are exporting to. You can now use the newoption Export custom lines as split lines on the Options tab in the Export Drawings dialog

box to ensure that custom lines have the same appearance in the software you are exporting toand when printed.

Option Description

Exports all parts in the embed.

Exports only the embedded parts that areinside of the concrete element. Embedded

parts that are outside the concrete elementare ignored. If an embedded part is partlyinside a concrete element, the exportedgeometry of the embedded part is changedto cut.

Same as the previous option, but onlyembedded parts with class specified in Cutouter only classes are taken into account.
