Floor Shape Editing “Add Split Line”


I managed to make a script that copies shape points from floor to floor, and it kinda works, except, some split lines between the original points, do not follow through, and they get joined to other points instead.

In other words, the points are copied fine, but the split lines may not always come through the same.

I cannot find a node that copies or manages split lines in floor slabs, like I can do with shape points.

Anyone has some ideas how to achieve this?
(possibly without Python, but if must be, I can try that too…)

Thank you



any ideas?
