http://www.zwsoft.com/forum/viewthread.php?tid=2546 Hi when I give command overkill n deldupl after processing 2% zwcad gets hang and message display wait for application or close. drawing is very small in size and have 16000 objects. softtech 2012-12-20 18:24:49 http://www.zwsoft.com/forum/viewthread.php?tid=2546&pid=16461 I think maybe you have selected too many objects. I tried to overkill 10000 objects and it stucked at 6%, but it finally resumed and successfully overkill after a long time. So I suggest that do not select too many (1000-2000 at most). huangy8949 2013-01-10 11:58:13 http://www.zwsoft.com/forum/viewthread.php?tid=2546&pid=16460 [b]Reply [url=http://www.zwsoft.com/forum/redirect.php?goto=findpost&pid=16459&ptid=2546]4#[/url] [i]huangy8949[/i] [/b] yes all objects softtech 2013-01-10 10:54:30 http://www.zwsoft.com/forum/viewthread.php?tid=2546&pid=16459 How many objects you selected for overkill?
