Retrieve 2nd level space boundary information in the IFC file
Hi, I am trying to get the IfcRelSpaceBoundary and IfcRelSpaceBoundary2ndLevel information for analysis. I have the sample IFC file with three rooms. As shown in the images below, I used ifcopenshell to inspect but it seems that such information is missing. However, I found that there are indeed "2nd Level" information in the IFC texts. May I know how can I retrieve the 2nd level space boundary information from the IFC file?

It is a while since I looked at this, but you may find some useful code in this IFC to gbxml tool: https://github.com/brunopostle/IFC-to-gbXML-converter
