I have seen occurrences pop up for no apparent reason. I use CIS, so never edit a part's properties, other than to link (change) it to a different part from the database. In the past, there was a bug that would generate occurrences, and that was fixed. I think the variant editor also causes oddities, but it's been awhile since I messed with it. The, um, occurrence of occurrences "incorrectly" popping up seems to have become less frequent. It's never been a problem for me (my designs are flat) but it is annoying in the property editor. eric ----------------------------------------------------------- To subscribe/unsubscribe: Send a message to icu-pcb-forum-request@xxxxxxxxxxxxx with a subject of subscribe or unsubscribe To view the archives of this list please login at //www.freelists.org.
