Grasshopper

algorithmic modeling for Rhino

Hi.

I'm trying to create a script where I can extrude polylines (which are room boundaries in floor plans and then create a gbXML file from that)

I'm at the point where I need to solve adjacencies between volumes in floor meets roof situations. 

This means I have a tree of planar surfaces that I want to subdivide using a tree of planar surfaces. 

I have tested the Honeybees Intersect Masses but that doesn't really work. Had it running all night nothing happened. (My original case has 1800 volumes). 

I've also tested checking which surfaces are intersecting and doing a solid trim with all of those and then an inverted solid trim. But that's a heavy process and I haven't really been able to figure out all the cases where it goes wrong.

My last try has been to shatter every polyline at intersection and then do some kind of meshing over them (havent figured out the meshing part) and then compare to the original polylines which surfaces are inside perimiter. 

My mesh example uses kangaroo and WB by the way. 

Please help,

Thanks.
