In working with some of my software (older Cinema 4D for poly, or Rhino for NURBS) it seems it would be nice to work on a system of multiple scales. Let me explain.

Lets take C4D for starters. I can start with a cube and make it editable. I can place the cube as a child of a sub-division (MetaNURBs, yeah I know, it has little to do with true NURBs) object. So now the cube wil be sub divided on render. I can select the 8 points of the original cube and move them to make largh scale changes in the shape. But I can not do the same with the sub division unless I apply or collapse the sub division object. Then I can make more five modifications. But, I have lost the ability to make the large scale modifications. So here is what I am asking. Are there any modelers that allow just such a multilevel control at the same time. THe ability to manipulate a few control points for large scale changes, but be able to manipulate sub divided control points for medium or fine shape control,.. all at the same time? Without collapsing anything? Seems that this could be a powerful, and intuitive, way to model. Especially if it could be done in at least 3 levels (large, medium, and fine scale control.) OF course, changes would need to be able to go down and up the nesting. It may be difficult, but I can not imagine that it is impossible.  Are there any tools out there that already do this.

The same idea of multiple scale control points can be applied to NURBs as well.
