Floor with Multiple Boundary Follow Topo

Hi All,

There was graph uploaded by the creator of landform that helpsfloor follow topo.dyn (31.5 KB)
project points from a topography surface not only to the boundary but also to interior of a floor.

This graph doesn’t work if the floor has an interior boundary, for example a patio surrounded by a planting bed. I was wondering if anyone has some insight on how to split the boundaries up and combine them separately and get the graph to run.

Many thanks!
