Coincident Edge

A coincident edge is a nasty issue with wireframe solid models. A non-manifold model is created which upon visual inspection seems to be manifold. The cause is a coincident edge. Three node points on the model are involved in one of these: they link up in a triangle pattern. However, the vectors that make up the sides of the triangle run parallel to the base. It looks like it should be fine, but when the 2-Manifold method is run to check the model?s integrity, it fails.
