Surface that Won't Render

In the attached I have a surface that does not render. No matter the display mode, it shows up wireframe.

Problem (110.1 KB)

The trim curve is a mess.

_UntrimAll surface keeping trim objects. _Explode curve and check _Dir.


Zooming in on the area shows many tiny curves in opposing directions

and other unclean parts after removing the tiny curve mess

Once cleaned up and joined together it’ll trim properly
