Undoing a Face
You may want to undo a face you have just generated (before specifying the z-value).
The effect of pressing UNDO when using the following GEN FACE options is:
• Sing Auto -- the last face specified will be removed.
• Singl Manl -- during creation of a contour, points will be removed. If you have finished defining a face and have pressed END, pressing UNDO results in the removal of the entire face.
• All In Prt -- all faces generated automatically will be removed.
• With Holes -- all faces generated automatically will be removed.
