Matching Trees properly

Hi guys,

I still have a major issue with this tree matching. In order to match the polyline tree and the vector tree properly I need to keep the first structure intact, with only «null» value instead of the duplicate lines. But I don’t understand how it groups my vertices… because in the end it remove to much geometries… (1.6 MB)

You just want to remove duplicated polylines and match them with respective extrusion vectors?
Then, this could be another way, but there are many “0” amplitude vectors… (1.6 MB)
