I'd like to find the units that a step file was saved with.
I can get the conversion factor to SI using http://www.opencascade.org/org/forum/thread_7149
However I would rather get the actual unit name. I'm using this code:
Standard_CString unitname = Interface_Static::CVal("xstep.cascade.unit");
However it's always MM even when the step file has different units.
How should I be doing this?
