Scaling loop to 0 creates a geometry error

Rhino SubD
3

Hi @BrianJ,

sure: Rhino_9_SubD.3dm (59.4 KB)

and here a video:

It seams Rhino doesn’t do a cleanup, and merge the endpoints to one point. First I’ve tried to scale the loop in one step, but Gumball doesn’t do this, see here: Gumball scaling with SHIFT and 0 value not working

Thanks

Michael
