Hi,
I create a six surface "box" building and put a room tag in this building in order to get a 'space". However, when I exported it as a IFC file, i found there is no slab and roof in the exported IFC file. Anyone suggestions?
By the way, how to correctly creat a room that considered having a space so I can exported as gbXML and IFC file?
Thank you!
