My "offset" would not work either. However, when I went to "wireframe" it did activate, before going to wire frame it was just grayed out. Now, I can highlight "offset" and then highlight the graphic (a 2-d circle)(the circle turns RED, indicating it is highlighted. I can see the "offset distance" in the window, but when I put an offset distance in the box, nothing happens. I've tried several times, but nothing ever happens. Any suggestions?
(I re-wrote this for clarification)
