Intersections trouble (jsut to post)

[Anonymous]

Don't know if this is a known issue, so posting.

I had a trouble with the intersection with a wall and a mesh.
And it does strange things in the elevation.
(see the oblique line in the image)
In the elevation, they coincide in the same surface.

I first thought it had to do with shadows, but when doing a solid elements operation, it was solved.
AC should take one of the two (mesh or wall) to decide witch color it should be.
Not trying to combine the two.
