| Summary | 0029864: Modeling Algorithms - BRepBndLib::AddClose() returns Empty box for triangulation-only Faces | ||||
| Description | Description of the method BRepBndLib::AddClose() says: //! Adds the shape S to the bounding box B. //! This is a quick algorithm but only works if the shape S is //! composed of polygonal planar faces, as is the case if S is //! an approached polyhedral representation of an exact //! shape. Pay particular attention to this because this //! condition is not checked and, if it not respected, an error //! may occur in the algorithm for which the bounding box is built. //! Note that the resulting bounding box is not enlarged by the //! tolerance value of the sub-shapes as is the case with the //! Add function. So the added part of the resulting bounding //! box is closer to the shape S. It is not very clear in which cases this method could/should be used, but since current implementation completely ignores TopoDS_Face, it returns an Empty box for triangulation-only Faces (without Edges/Vertices). It is suggested either fixing this limitation, or improving description of the method. | ||||
