the following code snippet produces different results in two separate computers with exactly the same setup: Win 7 Pro, x64, OCC 6.9.1
TopoDS_Shape* OpenCascadeModeler::sewFacesToSolid(std::vector<TopoDS_Face*> faces)
if(faces.size() == 1)
for (int i = 0; i < faces.size(); i++)
TopoDS_Shape resultshape = sewing.SewedShape();
With the same model geometry consisting of 129 faces (a house with blind windows, blind doors and some dormers) one computer delivers a resultshape of type TopAbs_SHELL (right) while the other delivers a TopAbs_COMPOUND (wrong) consisting of 7(!) shells.
I compared source code, model geometry, OCC library version and computer setup between both machines and they are identical as far as I can see. Am I overlooking something? Is there some non-deterministic behavior in the SewedShape() method?
Thanks a lot in advance.
