[BUG] BRepClass3d_SolidClassifier::PerformInfinitePoint fails

Timo Roth's picture
Forums: 

The appended solid has a negative volume.
When I try to correct its orientation via BRepLib::OrientClosedSolid it is not changed because BRepClass3d_SolidClassifier::PerformInfinitePoint gives a wrong result.

In order to reproduce the problem you can use the following Draw-commands:
restore solid.brep s
vprops s
solidorientation s
vprops s

By the way, isn't the help string for solidorientation in Draw wrong?
It is:
"solidorientation : orientsolid myClosedSolid"
Shouldn't it be:
"solidorientation : solidorientation myClosedSolid"
