Ok I also put this here,: Blender allows you to use unconnected edges wich also can be subdivided, wich provides you with a curve based modeling workflow without some of the disadvantages
I’m using this method since some year, and I would not miss it. Mainly because I can seamlessly integrate it with other modeling workflows. Maybe some other DCC developers might be inspired to implment such a feature.
And btw these edges are not 2point polys, there is no dealing with additional geometry before rendering.
So its more of a paradigm shift than an actual technique.
