Help!

[robyrrr]

hello Guys i have a problem : i’m doing a dynamo graph to run a generative design study on space distribution in revit trough refinery, but after i select the room from revit and after i do the bounding box to allow the creation of a container to give as input for the package of the design options inside the room in the packing.packrectangles node , it doens t take into consideration the columns, so that the spaces that i have to put inside the room overlapses with columns… but i would like the generative design study to understand that the columns shoun t be part of the generative design surface… is there anyone that can help and suggest a strategy to solve this? i attch the screen of the nodes where you can see the solid that doesn t take into consideration the pilaster but then when i convert as rectangle to give it as input in packing it unificates everything into one single rectangle…
