SubD with sharp corners?

[davidcockey]

@simonsais

hey there! i was wondering why the outer edges of subd dont have sharp corners like thos in t-spline. in there it is defined by the edge flow. but in rhino subd all outer edges are smooth.

is there a way to get control over that like in t-splines and fusion and have sharp outer eges?
