In the attached file I have a solid that I created using advice received from another post.
However, I started getting all kinds of weird behavior one the same surface that is causing problems the attached example. In the original file, joining the surfaces created a closed polysurface but it looked like this:
After I copied the source to a new file, I got a different weirdness with the same surface. If I try to cap the polysurface, it creates the cap but does not join all the edges.
I get the same problem if I create the pentagon surface using planarsrf.
I am curious what is going on here and how I might correct.
