SolidWorks
• SolidWorks is an industrial-strength 3-D solid-model based computer-aided design (CAD) system.
• In SolidWorks, you sketch ideas and experiment with different designs to create 3D models.
• SolidWorks is used by students, designers, engineers, and other professionals to produce simple and complex parts, assemblies, and drawings.

M4(III) 4IAT 106: Intro. to SW
SolidWorks is ASSOCIATIVE
• Parts, drawings & assemblies all use the same database.
So?
• Any change made in any of the modes (i.e. Part, Assembly, or Drawing modes) is automatically reflected in the other modes immediately.
What’s it mean that SolidWorks is associative?
M4(III) 5IAT 106: Intro. to SW
SolidWorks is FEATURE-BASED
• Feature: smallest building block that can be modified individually.
• Features are building blocks of the parts (shapes and operations).
M4(III) 6IAT 106: Intro. to SW
SolidWorks is PARAMETRIC
• Dimensions in the model drive the geometry of the model.
• Modifying the dimensions changes the model.
• Dimensions and relations are stored in the model.

Getting Started with SolidWorks
On opening SolidWorks, the SolidWorks window and Resource Task Pane are shown (details may vary depending on version)
M4(III) 8IAT 106: Intro. to SW
Opening a New Model File
New button (toolbar):
• New SolidWorks Document dialog box is displayed:
M4(III) 9IAT 106: Intro. to SW
File Types
• Modeling– Part (*.sldprt)– Assembly (*.sldasm)– Drawing (*.slddrw)
• Templates:– Part Template (*.prtdot)– Assembly Template (*.asmdot)– Drawing Template (*.drwdot)

How do we actually build a Part?
• Build parts by combining features
Ok how do I make a feature?
• Build feature by drawing a 2D sketch and extruding it into the 3rd dimension:– Use familiar drawing tools.
• The sketch does not need to be dimensionally accurate.– Just needs to represent basic shape (topology) of
profile:• Number of sides• Relationships between elements (parallel, etc.)
M4(III) 15IAT 106: Intro. to SW
Features
• Features are the building blocks of parts.
• Features are the shapes and operations that construct parts.
M4(III) 16IAT 106: Intro. to SW
More Shape Features
Cut feature• Removes material from
part.
• Created from 2D sketch.
• Must be attached to rest of part.
Hole feature
• Removes material from part.
• Works like intelligent cut feature
• Usually corresponds to mfg process (eg countersink, thread, etc.)
M4(III) 17IAT 106: Intro. to SW
Shape Features
Base feature• First feature in part.
• Created from 2D sketch.
• Forms work piece to which other features are added.
Boss feature
• Adds material to part.
• Created from 2D sketch.
• Must be attached to rest of part.
Two boss features
here!
• gothic boss
M4(III) 18IAT 106: Intro. to SW
What is this term “boss”?
It’s medieval history• In Gothic architecture a boss is a decorative element covering
a joint.
“Boss” is a skeuomorph• Go look skeuomorph up—it is a really important design
concept!
M4(III) 19IAT 106: Intro. to SW
Operation FeaturesFillet feature• Used to round off sharp
edges.
• Can remove or add material.– Outside edge (convex)
removes material.– Inside edge (concave adds
material.
Chamfer feature
• Similar to a fillet.
• Bevels edge rather than rounding it.
• Can remove or add material.
Fillet features
M4(III) 20IAT 106: Intro. to SW
Feature attributes
Sketched Features
• Shape features have sketches, are based on sketches
• Sketched features are built from 2D sketches (profiles)
Operation Features
• Do not have sketches
• Applied directly to work piece by selecting edges or faces
M4(III) 21IAT 106: Intro. to SW
Constructing a Model
• Sketching on one of the default planes– Front, Top, and Right

Sketch the 2D profile
Extrude the sketchResulting base feature
Creating a Rectangular Box
1. Select a sketch plane.
2. Sketch a 2D profile (a rectangle).
3. Extrude the sketch perpendicular to sketch plane.
Select the sketch plane
