http://www.zwsoft.com/forum/viewthread.php?tid=1283 often, when I undo I have very annoing problems. For example, now I'm modeling a 3d building. When I undo, the program, instead of undoing the latest command, just changes the view. Same thing happens sometimes when I'm working on a 2d drawing and I do some operations with layers (for example I turn off one layer). In this special situation the program doesn't undo the lasto operation with layers but jump just to the previous one. Very annoing!!!!!!! is there any way to avoid this situation? spritz 2009-04-09 19:00:52 http://www.zwsoft.com/forum/viewthread.php?tid=1283&pid=11372 Yes Sir, but we are all devoting to the enhancement of ZWCAD 2009. I suppose we could not maintain ZWCAD 2008i at present. Anyway, a great deal of improvement has been made on ZWCAD 2009. I strongly advise you to upgrade it. zw_admin 2009-05-14 10:19:08 http://www.zwsoft.com/forum/viewthread.php?tid=1283&pid=11316 <P =Msonormal style="MARGIN: 0cm 0cm 0pt; LAYOUT-GRID-MODE: char"><SPAN lang=EN-US style="COLOR: #1f497d; FONT-FAMILY: 'Arial','sans-serif'"><FONT size=3>We have almost reconstruct UNDO module in ZWCAD 2009 for the enhancement fo it.
