Hi,
after importing several parts as ply-files via cadmesh (GitHub - christopherpoole/CADMesh: A CAD file interface for GEANT4), I sometimes get geometry warnings even for simple parts such as this box.
Does that mean that my geometry export from the cad program is faulty? I would expect no errors/warnings here⦠Makes it difficult to distinguish between actual overlaps, as for some parts generated points are not inside as in this example but outside
Checking overlaps for volume mesh105 (G4TessellatedSolid) ...
-------- WWWW ------- G4Exception-START -------- WWWW -------
*** G4Exception : GeomVol1002
issued by : G4PVPlacement::CheckOverlaps()
Sample point is not on the surface !
The issue is detected for volume mesh105:0 (G4TessellatedSolid)
generated point (625.785,-506.69,-149.825) is inside
*** This is just a warning message. ***
