IFC export ignoring rotation and elevation of survey point

Hi! we are exporting an IFC with General parametric export, and mapping the model position using the "survey point only". The survey point is placed in the model pointing at the desired north angle, and with an elevation of -35500mm because the collaborating architects are working in revit, and using a different project origin. 

When we export the IFC, its using the correct point for the origin, but it ignores the rotation and elevation of the survey point. What are we missing?

 

These are the settings:

this is the outcome. the project origin is positioned in the correct place, but the model is not correctly rotated and the height is ignored.

This is how it should be rotated

Have you tried the "Survey Point and Project Origin" option?

You would of course would have to set the Survey Point properly in Archicad before IFC export.
