Introduction to AutoCAD 2006 2D and 3D Design

The following two examples demonstrate the construction of 3D faces using the 3D Face tool from the Surfaces toolbar. A 3D face is a triangular or quadrilateral flat (planar) or non-planar surface i.e. a surface with either three or four edges in 3D space. Lines or other surfaces behind 3D faces can be hidden by using the Hide tool.
At the command line:
Command: enter 3dface right-click
Specify first point or [Invisible]: enter 60,230 right-click
Specify second point or [Invisible]: enter 60,110 right-click
Specify third point or [Invisible]
Specify fourth point or [Invisible]
Specify third point or [Invisible]
Command:
Call the Mirror tool and mirror the 3D face about 190,110 and 190,230.
Click on View in the menu bar and on 3D Views in the drop-down menu which appears, and click again on SW Isometric in the sub-menu which comes on screen alongside the drop-down menu.
