Flip matrix grasshopper

[Alessandro_Barbisan]

Hello guys, maybe it’s simpler than I think, but I can’t manage to perform a flip matrix separately within each branch of my tree shown in the figure. Each branch is a separate surface. Can anyone help me?

I think I’d try with the path mapper.

@martinsiegrist Yeah, I was working on it, but I can’t find the correct syntax for the mapper

Please share I Grasshopper definition

@martinsiegrist i found the solution:

This solution doesn’t seems to be true as long as you have overlapped branches in your data tree .
This only works as long as you don’t add a component which complex your tree .
You have to Simplify and use this in path mapper instead : {A;B}(i) --------->{A;i}(B) so it works in all cases .

And even then:

you will only be able to flip matrix as a generalization (i.e. when you don’t know the structure of the branch labels) if you reduce to path indices.

I’ve followed your suggestion, and everything works perfectly. Thank you!
