Max display outputs? parts of model not showing

I’m pulling my hair out trying to figure out why part of my model is not showing up. The base section has 3 options: none, 2in, 12in but do not show correctly in the SD app, but appear fine in my window so it is difficult to pinpoint. Geometries either made from embedded curves or are embedded meshes. Any reason why this might happen?

Hi @curtisdoesthings,
could you narrow this down to a smaller model which you can share here?
What type of geometry is it that is not showing up?

The base of the model is not showing properly for the 3 variations: None, 2in, and 12in. this is composed of internalized meshes and meshes made from internalized curves. The geometry either doesn’t show or is in the wrong place; please advise.

Here is a reduced script, base is lower right in the canvas. Let me know if there’s anything else you need. Thanks for your help.
