Thank you for the response, I'll have to check on that. One other thing, when you DXF a drawing out of catia and into AutoCad there are alot of extra lines or lines that are to long what causes this? Is AutoCad more exact than Catia. Just wondering everything I know about Catia is self taught but i am very glad that I found this forum. It has been a lot of help.

thanks for your help,
Steve
