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.



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)?
