I suspect there’s been requests for this already, I’ve seen a few post related to creasing but not sure how related to this they are. I am fairly new to Rhino, I’m trying to implement the software into my workflow. One thing I use often in other apps is the ability to moderate the intensity of the …

@PaulS The command to try this out in latest WIP is _Sharp

“Crease” in Rhino has a specific meaning of a sharp break in smoothness of a surface. Along a crease the tangent direction is not unique - it depends on the side of the crease. Crease in Rhino is used mostly in SubD modeling. In Rhino “kink” is usually used for sharp break in smoothness of a NURBS s…

I was asking for SubD control point weights four years ago… SubD Control point weight - Serengeti (Rhino WIP) - McNeel Forum [image] SubD Control point weight Serengeti (Rhino 8 BETA) Hi, Martin, Thank you for the suggestion. Rhino SubD control net vertices don’t have …

@dalelear is working on this project currently. He can update you on it’s progress if appropriate to do so at this time.

I am not sure I fully understand all of it so let me explain myself with a picture. I use Blender a lot for all my meshes needs. In it, you can decide the “intensity” of the crease [edge_creasing_in_blender]

Rhino 8 will have SubD sharp edges. This basically a “weight” you can set on an edge to make it look somewhere between a smooth and crease edge. [image]

Yes! Exactly what I had in mind. Thanks @dalelear for the update, that’s indeed very exciting

[image] Dale Lear: Rhino 8.1 will have SubD sharp edges. This basically a “weight” you can set on an edge to make it look somewhere between a smooth and crease edge. @dalelear When ToNURBS is used on SubD with intermediate sharpness edges will the resulting NURBS surfaces be rational or non-…

There are no changes to the way SubD to NURBS conversions work. The ToNurbs command will continue to create non-rational cubic NURBS surfaces. The ExtractWireframe command will continue to create non-rational cubic NURBS curves. Away from extraordinary vertices, the conversion to NURBS is geometr…

Wish: Weighted Crease edges

Awesome! Thanks for letting me know @theoutside
