IFC geometry - Space Boundaries


Can anyone recommend an appropriate forum for asking questions about Industry Foundation Class geometry?

I am parsing IFC and interpreting the geometry, focussing on space boundaries.(IFCRELSPACEBOUNDARY)

All the space boundaries associated with a particular space are offset by a certain distance. The offset distance is different for different spaces. The 6 faces of a specimen 6-sided space fit together perfectly - but these faces do not even begin to fit with the adjacent space. What am I missing?

The IFC has been generated using the Alternative IFC GUI in Revit using IFC Coordination View 2.0 using IFC 2x3_TC1 schema with the option to export 2nd level space boundaries.

I am aware that there are tools for interpreting IFC files in java e.g. IFC Tools Project, but I am using Python for the developmental stage.
