Rhino/Grasshopper Layer Data Matching Issue After Cutting Surfaces

[inno]

@JohnFrost

I had been doing test and human component is not the problem. I think that is a problem of the logical routine.

well, to be fair that was little to no doubt about that

isn’t this the exact same issue you had a few weeks ago?

Nor sorted trees

the Repeat Data is fine as long as you need to manipulate that data further, otherwise (if for instance you need it just to tell GH on which Layer to bake stuff) it’s superfluous, because GH works on the principle of Longest List, so this is enough: [image] if you want the data tree structures to match (so also number of Items per branch) you can do this, as suggested earlier: [image] do not be bothered by the different path addresses the Layer structure has: those numbers are for us human…

just graft the output of the entwine and it will work:

as in the previous thread, if you need to further manipulate the layer structure then you might want to use repeat data / longest list on the Layer tree like this (otherwise GH will automagically Longest List -> Repeat Last for you):

as for the previous, you can connect the Color output to a Preview to have a fast visual confirmation that colors (thus layers) are correct:
