Thanks Micheal.

I do understand that while polygons are better in some cases especially to make later changes...but in the end I need to have exact measurements since they will need to be machined at some point.
Please add some xnurbs to Moi :D

and yes after all these years Moi still impress me with its capabilities

Thank you!
