Hi Brian,

> I noticed that doing Rebuild, to create more points, helps a lot, so does mesh angle of 1.

Best not to do either of those things though - it's just a display artifact and the best thing to do is to just ignore it.

Be careful setting your view mesh angle setting to 1 degree because that will make for an extremely high density mesh to be generated on other kinds of objects and you will easily run out of memory that way. So you'll probably want to put that setting back to the default 10 degrees which already makes pretty dense meshes on most things already, just not on things with this particular kind of "broad but very shallowly curved" specific type of shape.

The actual surface is fine and will respond to any modeling operation normally here, and you can make those problem areas to be more refined at mesh export time by putting in a distance in the "Divide larger than" meshing option at export time.
