Don't worry.occasionally, rarely luckily, this message appears to me (see image). In this case I appeared after making two simple holes on a straight tube brush.
I ask you what may be, since you are better than assistance:finger:
I don't know, and it doesn't have anything to do with the current discussion...I have another problem with inventor 2009....
if I create a normal traction spring with all parameters (also accurate as it is checked at calculation) and carry it into a stp file, this is not exported and an empty file or error is generated.. .
Can anyone know why?
