Hi, after importing several parts as ply-files via cadmesh (https://github.com/christopherpoole/CADMesh), I sometimes get geometry warnings even for simple parts such as this box. 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 !

Thank you for reporting the issue! The code in G4TriangularFacet::Distance(p) has been improved to have better precision of calculation.
