Is there a function in Rhino 7 to match subd edges (naked edges or internal face edges) to some curve? Something similar like T-Splines tsMatch?
Align, use the to curve optionâŚ
To note- Subdâs have vertices, edit points and control points.
Use the edit points to get the match for which you are looking, subdivide your Subd to get a tighter match-

Dear @theoutside, to expand this topic a bit, is it possible to apply weights to subd edit points or control points? Is there some analogy with nurbs control points?
Up to this point I was thinking, less points = better surface. Now I am little worried that controling dense subd can be quite challenging.
Achieving similar result in subd in as shown below for midship shape requires more points (subd curvature based on extracted boundary)
below just some built midship structure for reference:
not yet. Weights are not implemented at this time.
Weights are cool, but can be troublesome because they donât data transfer reliably. Some programs accept them, some do not.
Is there a chance to see this in Rhino 7 service release?
anything is possible- But canât commit to that atm-
Are there any news on subd points weights?
Hi Lukasz -
This feature request is still on the Future list (RH-47061 - not visible to the public).
FWIW, a quote from that RH-47061 item:
Rhino SubD vertices will NEVER have exact analogues of rational NURBS surface control point weights.
The implementation of weighted SubD edges will likely involve display tricks to hide the added complexity.

weights are tricky too as they tend to not data transfer well. at tsplines we recommended not ever trying to transfer a weighted model.
