This is a solution I found that helps me with my workflow from Revit to LBT.
Getting an analytical model from Revit to LBT can be problematic to say the least. With detailed models including non-orthogonal geometry the analytical model from Revit has loads of problems so I’ve found it’s more reliable to export the gbXML from Rooms and then do all the tinkering in LBT, which can be streamlined.
Anyway, importing the gbXML produces rooms sort-of-ready for simulation as these are non-conditioned, have no program, etc. Instead of rebuilding the rooms I’ve done minor modifications the “HB Room” component to allow me to quickly set construction set, program, is_conditioned.
Maybe some of you will find it helpful.
In inputs:
replace _faces for _rooms
get rid of _names
outputs:
out and rooms
