Lines don't show in 3D

[Anonymous]

I have a 3D view and the line at the intersection of the wall and footing appears intermittently. The walls and footing are different materials but are part of a complex profile. All the wall/ftgs are the same profile. Any explanation out there for this?

Maybe the lower edge of the wall doesn't match the upper edge of the footing?

Sorry, I guess I didn't read your post properly. If the whole wall+footing system are one single profiled element then my suggestion is probably wrong.

If the lines do show on the same profile used in one position and don't show in another, than something doesn't work as it should, but I have no clue why.
