Crummy old offset corners still here

SolidWorks does a great job in extending offset curves to make “sharp” corners.
V6 offers no improvement over V5 on this.
Still the crummy little segments added.
This is a pain because the offset curves become topologicaly different from their parents, and it screws up data matching in Grasshopper.

Still can’t seem to find any real useful progress in this WIP…

At first glance, it looks like Rhino is using a simplistic, brute force method of getting something that looks OK at the corner. Apparently some inspired developer thought could be applied. Especially if others have done a better job of it.
