Thank you Robert,
Yes that's what I'm doing, and that's exactly what I needed to know thank you, and oh, meshes! That's why a good viewer is important ;-)
In several comments below the answer (https://stackoverflow.com/a/55963646/3904031) to my question I outline what seems to be a working Mayavi solution though there are still warnings. I'll follow-up on that with a new Stack Overflow question. https://i.stack.imgur.com/TRddq.png
For learning I think the API method is better for me, I'll then try the problem description file method once I feel I understand better what's going on.
So I think I'm okay for now. I really appreciate your speedy reply!
