New Editing Tools

A major 4.0 focus is easier editing. There are new editing technologies (Universal Deformation Technology [UDT] and feature recognition) that are not constrained by how you got there or where you want to go next. History lets you edit an object by changing the objects that it was created from. Overview video...

There are more than a hundred new tools and enhancements for editing curves, surfaces, solids, and meshes.
