Meaning: This shape might have surfaces that do not properly intersect, or the shape has gaps between the surfaces.
Recovery: This shape cannot participate as part of a solid as it is defined. You must modify the original symbol from which this shape was created so that the defined surfaces intersect more precisely. This shape can be used as a primitive shape underneath the parent designed equipment. Move this shape to the parent to resolve this problem. As a child of the designed solid, the software ignores this shape unless the shape surfaces of the symbol are improved.
