Just a wish...
Is it possible Subdivision command was not destructive ???
I would like to keep my original "polygon" model, just have a "visualization" of the subdivided object and can modified the surface like in a traditional 3D polygonal modeler.
Thanks for your very good job !
Thanks a lot Max !!
