ToNurbs, change edge position

[brt1]

The “Faces=packed” option of “ToNurbs” is very nice, but I would like to have some control on which SubD-faces to merge.
I attached a Mesh, a SubD generated by “toSubD” and the Polysurface from “ToNurbs” to show this.
As an alternative: Can anybody think of a workflow to move the surface edge of the periodic surface to the desired position without changing the surfaces CV-struture?

I think you can use the texture packing command to control more the edge subdivision.

are you referring to " SetPerFaceColorByFacePack" ?
Looks like the right way to go. I just found no possibility to decidedly group a special subset of subD faces, only this “automatic” solution.
Have to dig into it …

Hi @brt1 ,

If the srf is not periodic, I’d instead suggest using the Split command with the Isocurve option to split the srf where you want after ToNURBS.

thanks, works great too!
