Steve,
I would like to change the refgrid on my RBE3 to a different node, uncross-referenced.
the refgrid parameter is not writable. update_fields is not implemented. How to do it?
I would want to delete some RBE3s that don't have further use. How to do it?
I did reread what you told me about nodes and elements, but it seems RBEs are implemented differently.
Thanks,
Clark

It should be.  Are you sure you're not cross-referenced (check if refgrid_ref is None)?  Do you have an example?

Steve, Thanks for your continued help and for this prompt reply.
Bad on me. I'm not learning very fast. If I uncross-reference, I can change refgrid.
I have figured out the parallels between elements, nodes and rigid_elements, which I did not see before. This lets me del my unneeded RBEs.
More than half of my difficulty is with Python itself.
Sincerely,
Clark

I wouldn't be so hard on yourself.  There is a steep learning curve, but then it's pretty flat once you understand how it thinks.  If you don't know python well though, you've going to have a tough time.

A good IDE and a debugger help out a lot.
