I’m trying to use .stp files exported from Rhino 5 for subsequent import into the Quickfield finite element analysis package. This tends to work correctly for files containing incredibly simple geometry (eg a couple of rectangular extrusions), but anything more complex than this causes the Quickfield import to fail. Quickfield technical support have analysed the issue and believe that the .stp files generated by Rhino are faulty.
Does anybody have any knowledge of the issue of faulty .stp file generation and/or any fixes or workarounds?
Also, does anybody know whether any such issue may have been fixed in either Rhino 6 or 7?
Thanks in advance.
