vertical lines under roof elements in 3D

[Quirk]

Does anyone have any idea as to what causes the vertical lines under the roof elements to occur in all of the View > 3D View Options > in the lower list (from 3D Details through to Simple Shading with Shadows) but not in any of the upper list vectoral options?  and how one can remove them from the 3D model? They make the renderings unreadable.

Thanks

Hello Quirk,

Did you try to clic on this icon ?

That is the 'Trimming Bodies' on screen view option if you want a name.

It does look like Quirk has turned that on.

It won't print.

Barry.
