Anybody seen this before? Every time I try to perform a facing operation I am getting this same erroneous code, so I am having a hard time believing it's me... I should have stated it in my original question but this is with bobcad v24 build 376. Anyways, thanks again for any help you can give me, since I've been waiting for a call back from someone in tech support for 8 days now I guess it's been... nice way to treat a new customer, but I guess that's a subject for a different time. Thanks.
