Extracts the geometrical extents of the given Placement3D and considers potential transformation of its macro. The position (x,y,z) is the offset of lower left corner in front from the point of origin (the handle point of Placement3D) For panels, doors and areas or auxiliary lines, the point of origin is always zero (0,0,0) For InstallationSpace objects, bounding box is calculated as the minimal bounding box from all Placements3D The size of bounding box is calculated regarding the placement area and independently on installation space (in local coordination system). If it is not possible to get bounding box for an object, location and size is set to zero.
