Incomplete Section Cut Fills

The section cut fill on this example of an architectural model fills some areas at the section plane but not others. Any clues why this would be?
Thanks.

The fill appears only in areas with a close loop of section cut edges that are all in the same context.

Okay, thanks.

It’s actually a useful indication that the element is not a “solid”.

That makes sense.
Thanks.

Right click on the section cut and select troubleshoot section cut to help identify where the problem could be.

That is a good suggestion. I tried that and it found a several areas.


Thanks much!
