Revit Bug

[robertlevy493178]

Ok, This is an in place family made up of simple extrusions. Nothing fancy. It looks ok when I'm in the Revit project environment. When I do a print preview or when I print, it looks like the image attached.

These lines seem like they are coming from the "mesh" geometry which is not displaying correctly due to some sort of a bug. Does anyone know of a solution for this issue? Autodesk? Bueler?

I noticed that the problem is with the outer ring extrusion. I modeled it as a blend instead and now it displays properly. This is definitely a BUG.

Here is a comparison between the extrusion and the sweep print preview:

Was the initial version a vertical blend with the top and bottom shapes set to the same shape? Or was it a horizontal swept blend with a curving sweep path, and the start and end profiles set to the same shape?
