[image] What is InflateCrv? InflateCrv is a new feature in Rhino BETA that allows a user to select a closed planar curve and create an inflated or “puffy” mesh or SubD. With a post-operation on a SubD result (ToNURBS command), a NURBS surface can be created. Why InflateCrv? This feature is useful…

Very useful too @theoutside . If you guys four add and draft/taper value besides the depth value this could be really useful for labeling parts for 3D printing without the debossed labels needing build supports when printed. thx, Gustavo

[image] Gustavo Fontana: draft/taper value besides the depth @Kyle @DanielPiker This feature would be really appreciated by jewelrs and accessory makers. I’ve plenty of client paying (a lot) other software just for having this feature edit: IMO it should have a proper windows with all the …

[image] skysurfer: edit2: it also need an explicit control on the final height (achieved by a vertical Scale1D) Hi @skysurfer That was exactly what I asked for - and initially thought to be missing from the command. It’s actually there - you just need to type the desired height at the “root”…

Gosh! you’re right! Thanks! …Still a windows complete interface would enhance the UX a lot.

Of course the more I think about this the more I realize that the profile shape/draft angle/inflate-deflate mode are only subset features of a much bigger and more important set of 2 features: Does this work in 3D text, or just flat? Can this be in the inside of a ring for example, or even on a …

As far as surfaces or polysurfaces are concerned, in my opinion there are no problems. Today I tested it with FlowAlongSurface [3.PNG] [image] 16th-century knight helmet | Rhinoceros 9 WIP Gallery [gsdfgsdfg.PNG] [3.PNG] [2.PNG] [1] [InflateCrv |…

Good catch, thanks. This is changed now for the next WIP release [image]

In answer to 1. - The input curves do currently need to be planar (though not necessarily horizontal or all the same plane). The result can of course then be mapped onto curved surfaces like brvdln shows. Accepting non planar curves as input would require a different approach, since just making a s…

@DanielPiker in my 9.0.26069.12305, 2026-03-10 version the Shaded Preview doesn’t work. It’s just me?

Yes, the preview during the command is currently shown only in wireframe. This could be changed to shaded though. Also - agreed a proper options window and an option for nurbs output would be good - I’ll see what I can do.
