Hi Keith, it's difficult to tell what might be going wrong just from screenshots alone. Is it possible for you to post the 3DM model file of one of the more simple structured solids that is not getting normals going the right way?
If your solid has anything like self intersecting surfaces or degenerate surfaces that are tiny collapsed slivers, those are some of the things that can tend to confuse the mechanism that creates outward facing normals for solids.
