Summary	0029782: Shape Healing - Reading of invalid shape
Description	The attached file is invalid (not whole shape, but several faces), it has some edge curves, where start and end points are the same. This trouble was not fixed during import and the result shape cannot be processed by the most algorithms because of exceptions. It is need to skip bad edges and not to corrupt the full model.
