It would be very helpful, like it was possible with T-Splines. Thanx.
Have you tried the commands _UnweldEdge and _UnweldVertex? Use them in combination with sub-object selection.
It is working, thanx.
However, there is no button command for _UnweldVertex, does it means I have to make custom button for _UnweldVertex command?
@pascal knows if there are supposed to be buttons for that. But you can indeed always make your own.
Hello - there is currently not a button for that - it should probably be on the right mouse button of WeldVertices -

I’ll add that for V8, and yes you can edit that button in your setup and add
! _UnweldVertex
as the right mouse button command.

This does not work with SubD or am I doing something wrong?
Weld and Unweld operate only on polygon meshes, not SubD surfaces.
unweldedge works on subd
Odd, I unwelded the two halves of a simple SubD surface, the entire edge loop, yet it is still one item when selected.
you can split subds using the split at edgeloop command in the subd edit menu.
Ah, thanks, so in Rhino, one doesn’t use unweld to take things apart.
not for subd.
Use the Explode command to separate a disjoint SubD or mesh into separate parts.
Yeah, there’s two ways: Split or Unweld and then Explode.
