I just tried to get the new rounded edges to work and for my/our purposes it just doesn't. For example, I'm working on a hospital, 15 floors with 1000's of objects straight from revit (that sit flush against eachother), are you telling me that going through that model, merging objects and removing interior faces by hand to be able to use rounded edges is a better workflow than before? In 1.5 it just works.
That the new rounded edges behaves like the chamfer modifier doesn't make any sense. When I chamfer stuff I don't select all border edges and apply chamfer, I chamfer edges that needs to be chamfered, ie edges on the actual border of the form. And again, in 1.5 it just works.
I'm sorry, but you just made rounded edges non-usable for me and a lot of users.
