Issue with sorting a list

[Joseph_Oster]

I didn’t look at this code but didn’t you already have that in what I posted this morning?

Can't select split surfaces

Here’s a way using Shift Paths and Cull Pattern to leave only the cut pieces you want on each floor. Repeat Data is used to supply a Larger Than value of 0.5 to all floors except the top floor where 0.3 is needed instead.
