SubD as a Cage

In the same way we can use a Surface as a cage, is there a way a SubD can be used in the same way? With the notion of ‘Thickness’ that is affacted, again like surfaces (or height of region to edit, I forget).

Would be good since a SubD is nice to deform, and could allow for small local deforms.

Maybe under the hood it could work, even if it’s only with Quad topolgy objects, that form a rectangular patch.

Thanks for the suggestion… filed as

Thanks Brian. This was something I’ve wondered about for a while, since when you work on a last (in footwear) you want to relax it afterwards, ideally.

Have you seen this?:

Thanks Daniel - I will try it!

At the moment, you can use two methods for local or global deformations for faces SubD:

  • SoftTransform
  • Move Gumball to the right position, from this position use standard Gumball features

Hi Daniel,

I got this:

An error occured during GHA assembly loading:

Exception System.IO.FileLoadException:

Loaded up Rhino WIP, Grasshopper, dragged and dropped to special components, unblock, restart. Grasshopper has Mesh Cage Morph from Fattener V regarded as unknown.

Edit - Okay got it, I had to zip it up as a workaround to getting an IT guy to download it for me. Unblocked the zip rather than unzipping and unblocking the gha. Does that sound right, or was that just a chance circumstance?

Glad it is working for you now.
I think what sometimes goes wrong with unblocking is that Grasshopper ends up loading a different copy of a dll or gha from the one you’ve unblocked (typically one in your downloads folder and the other in your roaming/grasshopper/libraries folder). You also need to fully quit Rhino for unblocking to have effect, not just gh.
