REVISION NOTES
1. In the AutoCAD 3D coordinate system, positive Z is towards the operator away from the
monitor screen.
2. A 3D face is a mesh behind which other details can be hidden.
3. The Extrude tool can be used for extruding closed plines or regions to stated heights, to
stated slopes or along paths.
4. The Revolve tool can be used for constructing solids of revolution through any angle up to
360 degree.
5. 3D models can be constructed from Box, Sphere, Cylinder, Cone, Torus and Wedge.
Extrusions and/or solids of revolutions may form part of models constructed using these
3D tools.
6. The tools Union, Subtract and Intersect are known as the Boolean operators.
7. When polylines form an outline which is not closed are acted upon by the Extrude tool the
resulting models will be 3D Surface models irrespective of the MOde setting.
