Tabs for folded aluminum model

Hello
I did some complex shape generation in Grasshopper with some folding tabs.

I don’t think you will find a plugin that do what you want.
You must develop you own tool that iterate over the shapes and generate the tabs. It is good you use your planar shapes as reference but as you have some angles that will make interference you will have to deal with that.
Each object will contain the initial shape
some cutters in order to allow that there will be no interference with overs pieces
Some added pieces (the tabs)
The connectivity (if you want to engrave or mark it)
