Hi, this is an absolute beginner's question:
No matter what I try, I'm not able to measure the distance between two points in a .stp file - the measuring tool is greyed out all the time, although it is described in the online help file.
Is this a feature of the professional version only (and if so, can I upgrade from the standard to the professional version?) or do I just s.th. wrong?
Thanks in advance for your help!
