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.

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).
![Page 6: Lecture 4 – Part 2 Introduction to SolidWorks IAT 106 Spatial Thinking and Communicating Spring 2015](https://reader038.vdocument.in/reader038/viewer/2022110206/56649cf95503460f949ca08b/html5/thumbnails/6.jpg)
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.

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.)
![Page 15: Lecture 4 – Part 2 Introduction to SolidWorks IAT 106 Spatial Thinking and Communicating Spring 2015](https://reader038.vdocument.in/reader038/viewer/2022110206/56649cf95503460f949ca08b/html5/thumbnails/15.jpg)
M4(III) 15IAT 106: Intro. to SW
Features
• Features are the building blocks of parts.
• Features are the shapes and operations that construct parts.

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.)

• Created from 2D sketch.
• Forms work piece to which other features are added.

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!

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.

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
