[cgma-dev] testgeom_occ

[Rajeev Jain]

Thanks Jane for looking into this, we made some progress, I made the changes you made to cgm repo version, I'm using CGM repo version with OCC-6.5 not the merge-cubit13.1 branch - should I use this branch instead?

We made some progress with the change you made the error is now on line 6249 instead of 6233 in file iGeom_CGMA.cc, which is the subtract operation, the copy operation seems to have gone through, please see debugger o/p below:
