> Another ER that I want is ability to thicken a surface.

Hi Lish, use Construct / Offset / Shell for that one. When applied to a solid Shell will give a wall thickness to the solid, and when applied to a surface Shell will thicken it into a solid slab.

Check out the command reference here: http://moi3d.com/beta/moi_command_reference2.zip under Shell for some screenshot examples.

Hope that helps!
