Section Fill woes

Does anyone have an idea why this would happen?

I was working on this SU/LO file and updated the viewport. Suddenly part of my section fills disappeared. I went back to the SU fie and ensured the scene had been updated and then the file saved. Updated LO viewport again, but the problem persists.

SU:

LO:

Delete the edge from that group (in SketchUp)

I’ll take a look at that but it immediately raises two questions:

  1. I don’t remember doing anything to the geometry that would have caused the problem you identify;

  2. Why does it show OK in SU but not in LO (the basic puzzle as it is normally WYSIWYG)?
