Composites disappearing in section

[Jere]

Hey all. I'm having a problem with composites disappearing in my section views. In the attached image you'll see what i mean. If i go back to the plans and alter those composites (move them then move them back in place) they'll appear but then others will disappear.

My computer has 1.5 GB of RAM.

Any ideas?

Check and make sure there are not any duplicates of those elements. When you duplicate a 3D element, it disappears in sections (usually with the fills still visible but not the outlines)

Are the fills that do show in section also cut fills? The reason I ask is that maybe one of the fill categories in your Model View Options is not set to display the cut fills in section/elevation.
