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

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
