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
