This was done for ifc2x3 certification. In Revit, grid lines are at the document level and are really surfaces of linear extrusion have vertical extents. We don't have a concept...

I'm not sure if there is an IA that says that a grid must be associated to a level. So it would be possible if a grid had no axes...

Unaligned, not unadorned.

No progress here - the original point stands that IFC just doesn't have a good structure for grids. Ideally, grids would be associated with the building and have vertical extents,...

@WawanSolihin please put this on your queue.

Let me get QA to check on this.

buildingSMART has some specification of what the different exchange requirements are supposed to do: (https://standards.buildingsmart.org/MVD/RELEASE/IFC4/ADD2_TC1/RV1_2/HTML/schema/views/reference-view/index.htm)

We've identified this issue and hope to have a fix in a future update.

This is on our roadmap. I do have some UI questions about this. Is the expectation that you would have an IFC2x3 mapping, an IFC4 mapping, an IFC4.3 mapping, etc.?...

Check if this works: https://feedback.autodesk.com/key/LHMJFVHGJK085G2M - if it doesn't I'll ask around.
