Display problem with trapezoidal composite walls in section

I've got a display issue I can't solve: I'm using a lot of trapezoidal composite walls for a very odd existing building plan (don't ask...). The walls display correctly in plan and in 3d. However in section the lines of the outer skins of some of the walls are flipped, so that the cut lines appear on the inside of the outer skin.

After some experimentation I found that this flipping depends on which side of the wall the reference line is on as it passes through the section line. A section looking the other way flips the problem to the other wall. If the reference line of the wall on the left was moved to the inside of the wall, the section shown would display correctly, but a section looking the other way would show both walls incorrectly.

Changing the direction of the wall reference doesn't affect the problem and I'm seeing the same behavior with other trapezoidal composite walls. Everything works perfectly in plan and in 3d and regular walls using the same composite display properly in section.

Any ideas?

David:

I don't know the fix, but I am seeing similar behavior with all the separator pens.

Thanks for looking at this, David. At least I know its not something I'm doing wrong. Maybe the Graphisoft guys can sort it out some day.

I will make sure the developer team takes a look into this.
