Lesson 2
Learning objectives
Introduction to Solidworks Learn about various modes of Solidworks Opening and Invoking SolidWorks Tools Learning how to draw sketches Edit sketches using various editing tools. Create rectangular and circular patterns of sketched entities. Write text in the sketching environment. Modify sketched entities.
Solidworks is a feature based parametric solid modelling mechanical and automation
software. It can be used as the platform software for a number of softwares, i.e. youcan use other compatible softwares within the Solidworks window. There are number
of other softwares provided as Add-Ins with Solidworks, such as Photo work,
Toolbox and COSMOS/Works.
There are three different design environments provided in the Solidworks to reduce
complications in design;
1. Part Mode2. Assembly Mode3. Drawing Mode
Part Mode You can create solid models in this feature based environment. There
are three default planes (Front Plane, Top Plane and Right Plane) on which you draw
sketches. Complicated surfaces can be created with surface modelling when you are
in Part Mode. Also annotations can be added to the model within the Part Mode (eg.
Weld symbols, geometric tolerances, surface finish symbol etc.).
Assembly Mode You can assemble components of the assembly with the help of
required tools. Two methods of assembling methods are;
(a)Bottom-up assembly Traditional and most widely accepted approach ofassembly. All components are created in separate part document in Part Mode
and use when assembling.
(b)Top-down assembly Components are created in same assembly documentand saved as separate part files. They are used for assembling.
Drawing Mode This is the place where, documentation of the part or assemblies
takes place. Drawing views and details in the drawing views can be produced with
this mode. There re two forms of drafting done in SolidWorks.
(a)Generative drafting needs a 3D document (part or assembly) to generateviews and geometry
(b) Interactive drafting can design parts without any 3D geometry

DIMENSIONING STANDARD AND UNITS
While installing SolidWorks on your system, you can specify the units and the
dimensioning standard for dimensioning the model. You are provided with many
dimensioning standards such as ANSI, ISO, DIN, JIS, BSI, and GOST. You are also
provided with various units such as millimeters, centimeters, inches, and so on.
Other Important things with SolidWorks
Feature-based Modelling Feature is defined as the smallest building block that can
be modified individually. In the software these features understand their fit and
function properly. Hence, feature can be modified at any time during the design
process.
Parametric Modelling This is the ability of the software package to use the standard
properties or parameters in defining the shape and size of a geometry. Eg. You can
change diameter and no of holes by just selecting the feature and change the
dimensions and number of instances of the patterns.
Geometric relations Logical operations that are performed to add a relationship
(tangent or parallel) between sketch entities, planes, axes, edges or vertices. There are
two ways of creating these relations either by Automatic relations (applied
automatically when creating the sketch) or Add relations (add manually).eg.
Horizontal, Midpoint, coincidence etc.
Library feature saves features in this library and use when needed Feature Palette access ready to drop down parts, shafts, key ways, forming
parts etc.
Design table create multi-instance parametric components
Equations analytical and numerical formulae applied to the dimensioning ofthe feature or during or after sketching

Collision detection in assembly Physical dynamics - With this option selected, the component applies a force
to the component that it touches. As a result, the other component is moved or
rotated within the allowable degrees of freedom
Physical simulation - You can assign and simulate the effect on differentsimulation elements such as linear, rotary motors, and gravity to theassemblies. After creating a simulating assembly you can record and replay
simulation.
Seed Feature and Seed Component - The original feature that is used as theparent feature to create any type of pattern or mirror feature is known as seed
feature. You can edit or modify a seed feature. You cannot edit the instances
of the pattern feature.
Feature Manager Design Tree - The Feature Manager DesignTree is one themost important component of SolidWorks screen. It contains the information
about the default planes, material, lights, and all the features that are added to
the model. When you add features to the model using various modeling tools,
the same are also displayed in the Feature Manager Design Tree
Absorbed Features - Features that are directly involved in creating otherfeatures are known as absorbed features.
Child Features - The features that are dependent on their parent and whoseexistence is not possible without their parent features are known as child
features
Dependent Features - Dependent features are those that depend on their parentfeature but can still exist without the parent feature with some minor
modifications.
AUTO-BACKUP OPTION
SolidWorks also allows you to set the option to save the SolidWorksdocument automatically after a regular interval of time.
To turn this option on, choose Tools >Options from the Menu Bar menus; theSystem Options - General dialog box is displayed. Select the
Backup/Recover option from the display area provided on the left of this
dialog box.
Now, choose the Save auto recover info every check box. The spinner andthe drop-down list provided on the right of the check box are enabled. Using
this spinner and drop-down list, you can set the number of changes or minutes
after which the document would be saved automatically. By default, the backup files are saved in X:\Documents and Settings
\Administrator \Local Settings\TempSWBackupDirectorylocation (where X is the drive in which you have
installed SolidWorks 2008 and theLocal Settingsfolder is a hidden folder).
SELECTING HIDDEN ENTITIES
Sometimes, while working on a model, you need to select an entity that iseither hidden behind another entity or is not displayed in the current
orientation of the view.
SolidWorks allows you to select these entities using the SelectOther option.For example, consider a case where you need to select the back face of a

LEARNING ABOUT SKETCHER TERMS
The origin is a red color icon that is displayed in the center of the sketching
environment screen. This icon consists of two arrows displaying the X axis and the Y
axis direction. The point of intersection of these two axes is the origin point and the
coordinates of this point are 0,0.
The inferencing lines are the temporary lines that are used to track a particular point
on the screen. These lines are dashed lines and are automatically displayed when you
select a sketching tool in the sketcher environment. These lines are created from the
endpoint of a sketched entity or from the origin. Figure A shows the use of
inferencing lines to locate the point of intersection of two imaginary lines. Figure B
shows the use of inferencing lines to locate the center of an arc.
