I would like to have a clean edge,the image below is

Thats also the reason why i tried to do it with a mesh from the output of the meshBrep component.
I know there will be distorted faces with less than 4 vertices, thats ok for me, i just dont get it done:

I am not sure what could be a workaround.

Maybe someone knows?

Thanks!

, when i try to unroll it fails.

Also i have a huge amount of different domes, thats why i kept trying in another way.

Sorry for not telling from beginning the final result i was trying to get,i want to get something like this, in the best case a mesh for having it later easier to prepare the 3d print.
When i read it now i really should have choosen another title.

Thats why i thought about using the output of the meshBrep component, cause its already a clean mesh with all faces 3 or 4 vertices.
I tried it with the relative item component but without success, i think it could be possible. Or maybe there is better way to do thid?

You’ll probably need to use a plugin like “Turtle” which will allow you to deal with ngon mesh(for your faces that have more than 4 vertices…)LBSplit_reV2.gh (17.5 KB)

And regarding your curiosity, please follow below procedure…

1, Type and run “CreateUVCrv” command in rhino command line.
2. Select your “Trimmed Surface” and Enter.
3 Then, you’ll probably get your boundary & trimmed curves near origin point.

Thanks a lot,

surely i will need that in the process for other domes.

Thanks and a nice day!
