Issue with boolean intersections in vr 9.9

Use of the platform
1

Hello,
I am not sure if this issue is comming from opencascade kernel itself but in any case, I am facing some issues while using salome. I use a script that create a lattice structure, and fuse them together. the script outside of being slow works perfectly. perfectly in vr 9.7 of salome… since the last two versions (9.8 and 9.9), the boolean operation when I select the options remove extra wires and detect self-intersections fails (in python i.e., geompy.MakeFuseList([body1,body2], True, True) )

here I am uploading the .hdf file,
Study1.hdf (2,8 MB)
if opened by salome vr 9.7 and we try to fuse the bodies latticeStructure and dummyStructure with the two options turned on it works as intended without issues. if we do exactly the same in vr 9.8 and 9.9 this gives an error ‘error can’t build object’.
would be great that this could be issued (I made the same post in the old forum with the release of the 9.8 vr) I would like to use some of the new tools introduced in the last updates inside my workflow and right now I can not do it.
regards.

Hello @franco.ota ,

This issue has been adressed by developpement team and corrected in versions 9.11 and above.

Please get the latest version of Salome and check that it works perfectly now.

Hello Mohamed,
thank you for your kind answer, in the meantime I used previous version, and since I finished this project. in any case, great to see that the boolean operation are working better, this is one of the ‘weak’ points in salome in general, so any improvements are more than welcome!
regards,
