Finding Border Edges in Polygons
Okay, I've seen questions about this often enough now to warrant putting this in here.
There are numerous operations which may result in faces not being connected properly. Faces may be missing due to deletion. However, faces don't have to missing to cause problems, edges may be swapped, normals may be reversed, etc. All this may lead to problems such as non-manifold geometry or the innability to boolean correctly. To make these offending edges easier to find, turn on the border edge display option and adjust the thickness to suit. The image below shows a cube with the face deleted. Note the thicker top edge in shaded, wireframe, and edge mode. The border thickness is set to 3.
