Summary	0013962: Exception when drawing face without pcurves
Description	This bug has been detected while testing OCC13258 (see history, regression report 2006-10-16). Though the fix was attached also to OCC13258, thereby it is recorded as separate bug to facilitate its integration. The reason of the bug is that BRepTools::AddUVBounds() does not check the case when face has no pcurves; in that case returned Bnd_Box2d may be void. In turn, void Bnd_Box2d allows getting its values and returns non-initialized real values. Using these values may lead to exception according to a case.
Additional information and documentation updates	Documentation remark, added by ABV 2006-11-22 16:48:34: Changes: - Methods Get() of Bnd_Box and Bnd_Box2d now raises exception if box is void - BRepTools::AddUVBounds() adds natural bounds of the surface if face has no edges or no pcurves
Tags	No tags attached.
