Curved walls 3D intersections disappearing

[znj]

My walls look correct in 2D and even in 3D their base is visible, but the model is breaking on each segment. What could be the problem?

[Gerry Leonor]

see if there's anything that's hiding the top of the walls in a hidden layer. perhaps there's a beam or slab that's acting on them?

try a different 3D view. if you switch from Wireframe, to solid lines, to solid shaded views, do the tops still disappear?

Thanks, but neither of the suggestions help the problem. Seems more of a glitch, I am working in AC26 and noticed several bugs already.

How thin is your wall, and what radius are your curves? AC segements curved enterties for 3D representation, which might be causing self intersections, and hence the failed geometry generation.
