Originally something I discussed here: https://forums.buildingsmart.org/t/how-is-true-north-and-magnetic-north-stored-in-ifc-and-how-does-it-interact-with-grid-north/3491 When a map conversion is supplied, the true north becomes a calculated value at a particular easting and northing. For example, at Easting X...

In particular it refers to an [IfcCoordinateOperation](http://localhost:8001/schema/ifcrepresentationresource/lexical/ifccoordinateoperation.htm) between a Geographic map coordinate reference system, and the engineering coordinate...
The way profiles (and layer) sets work is that assuming you have: IfcElementType IfcMaterialProfileSetX -> IfcMaterialProfile(s) Then all occurrences of that type share that profile set. For example: IfcElement IfcElementType...
I recently found that IfcGeometricRepresentationSubContext pages were erroring out. After fixing that (I hope my fix is OK I'm not too familiar with the UML yet) I found the ordering...
