Besides using the Windows shortcut key Ctrl+Z immediately after
extruding an object, is there a way to undo an extrusion?
I guess the answer applies to most AutoCAD products. Specifically,
I'm talking about Autosketch.
Hi John D.
In plain AutoCad you can make a SECTION normal to the extrusion
direction to recover you initial contour and then erase the extrusion.
Depending on how you choose your section angle, you can produce for
instance an ellipse from a cylinder.
good luck & grtz, Erik
