Sue, Yep, mine was also and out of date shape. It's pretty easy to find the offending shape. In the Status tab, click on the colored box next to "Out of date shapes". This will show you the bad shape (which layer), then click on the coordinates and Allegro goes to it. Gary Gary E.

I did had one of these last week. I had just upgraded to the latest ISR 15.5.1, and all of a sudden you get this message, drc out of date no matter how many times you run it. In my case, I had an out of date shape that was causing this. On my board the shape was very small and did not fill, so it was very difficult to find. ________________________________ From: icu-pcb-forum-bounce@xxxxxxxxxxxxx [mailto:icu-pcb-forum-bounce@xxxxxxxxxxxxx] On Behalf Of Macindoe, Gary Sent: Wednesday, May 16, 2007 3:07 PM To: icu-pcb-forum@xxxxxxxxxxxxx Subject: [PCB_FORUM] possessed design! Hey guys, Allegro 610 Expert, Windows XP Pro. Well, my design has become "possessed"! No matter what I do, the Status shows DRC errors as "Out Of Date" with 0 errors: - I ran Tools -> Database Check (both checked), passed squeaky clean. - I ran Tools -> Update DRC, resulting in "No DRC errors detected". - I ran "Update DRC" from Drawing Options window, Status tab, also resulting in "No DRC errors detected". - I got out of Allegro, got back in, then I repeated the above. Anyone ever see this one? In all my years using this tool, I've never seen the DRC errors stay "Out Of Date" after updating. Thanks for any help! Gary Gary E.
