Documenting 2D 3D

• Essential Understandings
• Create various solid primitive shapes.
• Use software to thicken a plane surface.
• Apply the Revsurf and Revolve commands.
• Prepare and extrude a closed polyline to create a
  3D model.
• Hollow out a shell from a 3D model.
• Prepare an extrusion pathway and sweep a 2D cross
  section.
• Apply the 3D fillet and 3D chamfer commands
• Understand and apply Boolean operations union,
  subtract, intersect.
• Prepare multiple 2D cross sections and Loft a 3D
  solid from them.
• Understand and apply the concepts of model space
  vs. paper space.
• Layout, apply and scale multiple paper space view
  ports.
• Compare, contrast and evaluate various methods to
  document 3D models.
• Create a virtual solid model from a set of plans
  and bill of materials.
• Modify, customize, and improve a virtual solid
  model.
