Dear community,
I’m trying to construct a small structure from several unequal faces. Each face should be bent later and bolted to the other via a screws. Therefore I wanna add tabs on the inside of each face (similar to the picture I uploaded - but only inside).
Do you have a hint for me on how to add the tabs of each panel/face? And finally: how you to unwrap them with each face? I upload the grasshopper file I already working on but I’m not able to add the tabs.
Tanks alot

Hello
I will prefer to make a script to control that but here is a way.
In order to associate tab with a face, you better use DataTree.
So I use edges for each face of polygon => Deconstruct + Deconstruct
I scale a bit the tab, like that when unioned with the face they will not touch
After that I Union the tabs and the face
Then Unroll the brep (tools in Wombat, OpenNest, Lunchbox …)
Then Nest or Pack (Openest or Nautilus)
Explode positions that will be on a future release of Nautilus
And a version with holes

Hello Laurent,
thanks for your inspiring workflow and the idea of using the edges and DataTree!
I just tried your GH file with wombat, OpenNest, Lunchbox 2020.6.3 and your Nautilus 0.9.2
Unfortunately I’m getting two unknown objects (Unroll Brep and ExplodePositions).
May you also know how to fix that issue with the plugins?
thanks again for the fast and amazing help! 
Hello
I wrote it. You can choose another unroll it is not a concern.
For the last it will be in a future release of Nautilus.
If you dont want blank components. Copy all components and paste in a new file.
Explode positions is now on Nautilus version 0.9.3
I’ll check it! Thanks a lot
