2. Learning Goals
Describe How AutoCAD SOLIDs differ from WireFrames and Surfaces
Create AutoCAD “Primitive” Solids
Box, Wedge, Cylinder, Sphere, etc.
Slice and Section 3D Solids
Use ACAD “Boolean” Operations to create Solids
Interfere, Union, Subtract
Combine Primitives to Make new Solids

3. Constructive Solid Geometry (CSG)
Standard “primitive” shapes
AutoCAD has six primitives:
box, wedge, cone, cylinder, torus, sphere
Primitives are moved into place with 3D commands to assemble object
Primitive are combined with boolean commands:
union, subtract, interfere
