Hi all, In the Rhino WIP we’ve enhanced SoftTransform . SoftTransform makes it easy to adjust large numbers of control points by applying a falloff influence to the transformation for surrounding points. Why is SoftTransform useful? Often called proportional editing, SoftTransform allows you to ma…

I noticed that while using the SoftTransform command, if I hold down the right mouse button during a rotation, the dark color on the surfaces disappears. matchsubd on srf.3dm (1.2 MB) Rhino 9 SR0 2025-10-7 (Rhino WIP, 9.0.25280.12305, Git hash:master @ 0a5e40a60821c67ce68d95a275fda420265d863…

Something else… with SoftTransform enabled, select a mesh face and run the command again. A red transparent sphere is shown to change the radius using the mouse. [image] This sphere is not shown when selecting control points using _PointsOn I see the sphere however when direct selecting vertices…

[image] Joshua_Kennedy: Yep, let’s get that fixed. I opened RH-89452 . Hi @Joshua_Kennedy I saw your method, but it’s very basic — only the Control points get colored. It’s not like the method in the picture, where the color falls on the object itself. Thank you. [3d-01]

My big concern with this is not slowing down Rhino as I think this shading could be quite expensive to calculate. I’ll give it a shot and see. I opened RH-90291 .

[image] brvdln: Another issue: it doesn’t seem like a behavior it should have when using the control points. I think the UVN directions work really well with soft transform. This is an unexpected result but maybe how setting the SubD surface point (as opposed to control net point) works? Here…
