Understanding AutoCAD Solids: Differences, Creation, and Boolean Operations, Slides of Engineering Drawing and Graphics

Learning goals for understanding the differences between autocad solids, wireframes, and surfaces, as well as instructions for creating and manipulating autocad primitives using 3d commands and boolean operations. Topics covered include the use of primitives such as boxes, wedges, cylinders, spheres, and more, as well as slicing and sectioning 3d solids and combining primitives to create new solids using union, subtract, and interfere boolean operations.

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
