|

At last, there is a problem in the assemblePolyhedra method. At least, I
|
|
think it is there. The problem deals with boolean operations on solids,
|
|
when one of the two contains entirely the other one. It has no sense for
|
|
intersection and union but still has sense for subtraction. In this
|
|
case, faces from the inner solid are stored in the unknown_faces
|
|
FaceList. And an error occurs in the execute method. This may be correct
|
|
for intersection and union but in the case of subtraction, one should do
|
|
that in assemblePolyhedra :

one of the solid should simply be ignored.
