I was trying to get the uv-min and max parameters from a face using ShapeAnalysis::GetFaceUVBounds(), and in one case I encountered a "Bnd_Box is void" exception in Bnd_Box2d. It was created by a surface and a wire on the surface. I can see that this line in the above method:
if ( ! sae.PCurve ( edge, F, c2d, f, l, Standard_False ) ) continue;
always continues. I suppose this shows that every edge of this face doesn't have a pcurve, but I am not very sure what it means. Does anyone know what might be wrong with this face, perhaps I need to use a different BRepBuilderAPI_MakeFace constructor? I use Open CASCADE 7.2.0.
