There goes: Rectangle, (copy/paste, with added parameters, of the UnitSquare case) Box (copy/paste, with added parameters, of the UnitCube case) and UnitCircle. (copy/paste, with added parameters and variable transformations, of the UnitSquare case) I've included a sandbox/built-in_mesh/ for testing the Circle case. I will include the Cylinder and Sphere case only if you think that the UnitCircle is of any use, since they use the same transformations .
Thanks.
