What is Gumball UVN? In the Rhino WIP , the Gumball now aligns with the Control Polygon when control points are selected in object mode. This alignment matches the directions used by the MoveUVN panel. When you manipulate the Gumball UVN, each selected control point moves along its respective control…

[image] Martin Siegrist: consistent It’s consistent in box mode… Moving control points in smooth mode doesn’t make much sense to me.

[image] Riccardo Majewski: Having at the same time handles for controlnet directions and handles for CPlane directions would be… superior! Even more, it could be like this: while dragging the grid-like handle, if you hold SHIFT it stick to the nearest CPlane ortho direction! [gumball] (Cur…

[image] Joshua Kennedy: This is currently possible when control points are on for a SubD. I think in your screenshot you’ve sub-object selected a SubD vertex. We’re still trying to figure out what to do here. hi Joshua, even talking about controls points in SubD breaks my brain, I hadn’t ever…

[image] Gustavo Fontana: What is this control point distinction about? Are the control points of a model ever any different (placement/count) than vertices? My understanding is control points are the vertices of the control net for a SubD. I struggled with the verbiage here too but I think it…

[image] Riccardo Majewski: While that make sense, this feels just wrong: [2026-03-17 14_30_41-Untitled - Rhino WIP - Perspective] Yes, that is jarring. I’ll probably draw it differently (on the surface) even if the movement behind the scenes is using the control net.

First off, thanks for the new enhancements to the Gumball! I have a few suggestions/feature requests regarding the UVN (Object) alignment mode: In Rhino 8, if I select a control point with the Gumball in ‘Object’ mode, its movement acts just like the MoveUVN command, as shown in the screenshot bel…

[image] Gustavo Fontana: hi Joshua, even talking about controls points in SubD breaks my brain, I hadn’t ever though that control points and SubD vertices are a different thing. And I’ve been modeling in SubDs for about 25 years. Same - I’ve never once turned on control points for a subd, alw…

I’m aware that some people may attack me again for repeating this for the millionth time, but the best approach is to give the users a full control to customize the Gumball to their own taste. Super Gumball is the correct answer. It can include a variety of extra handles that every user could activa…

Hi, sorry very late to this discussion but is this behavior the same UVN behavior being discussed here?Providing feedback that the UI was confusing to me and the result unexpected. Glad to elaborate if this is the expected behavior

Yes, that is the expected behavior when the gumball is in object mode. The movement along the control polygon is mostly for adjusting control points on a “smooth” curve. Clearly not great for a polyline. One option would be to disable the behavior in this case.
