How to 'UnJoin' a polysurface edge?

Hello,

I have a polysurface, upon which i want to Sub-Object-Select one of it’s faces, and rotate it using the Gumball.

RhinoFile: unjoin_help.3dm (135.0 KB)

Image 1: Original / What I have

Image 2: Aim / What I want

I believe the edge is joined, and needs to be detached. I tried UnjoinEdge command, which doesn’t seem to do anything. Is there something I am missing?

Thanks,

Yeah, that looks buggy to me… In principle this should work IMO.

If it helps, the UnjoinEdge command does work in the background. For example, when i use UnrollSrf on both these versions, I get different outputs (as they should work). But, when I use the Gumball to manipulate, they seem to be joined at the Vertex.

Could you take a look if possible, @pascal?

Looks buggy indeed. FWIW, if instead you rotate3d the lower edge, it works as expected.

Thanks @Gijs for taking a look.

I tried Rotate3D as well as Gumball manipulations, but It does seem to be joined. Maybe something is wrong with my polysurface itself? Could you take a look at the attached file, does your method work on that file?

Hi @Kaushik it’s indeed a hit and a miss
I’ve added RH-73908 Unjoined edge still gets transformed when face is transformed

Hi @brian
Can it be ported to Rhino 7?

We don’t have plans to port this fix to Rhino 8 7, no.

Do you mean it is not possible to fix for Rhino 7?

Hi -

It means that it won’t be fixed in Rhino 7.
