Hi SalomonD, yes for the shaded surface display surfaces are converted to triangles for rendering on the graphics card. The "Mesh Angle" setting is the maximum angle allowed between surface normals at polygon vertices. If the surface normals are wider apart than Mesh angle number of degrees then it subdivides it more until it is less than that.

If it's a larger angle it will result in the kind of display you show above but that can also help reduce display draw time on heavy models.

In the future I want to change how this works to be handled more automatically, like start with a rough angle and then do a higher density one in the background but that is fairly complicated to set up well.
