[cgma-dev] testgeom_occ

[Jane Hu]

You may try merge_cubit13.1 branch, this has some minor function
signature's changes, it shouldn't affect the result of running testcases in
occ.

Can you double check if a new_body is created in the copy_body process? I
suspect that the problem is still in the copy_body place, where it didn't
find underlining TopoDS_Shape. Then it could be just related to the OS,
which may be a bug there.
