Summary 0022454: Export /Import of valid model leads to lost of tolerances
Revision 2016-09-08 18:20 by bugmaster
Description Export of the attached model 1.brep (solid) and following import leads to lost
of tolerances. As result it (just expoted model) can't be opened in other
CADs(such as catia or pro/e) software correctly.
Tolerances before export:
========================
