Receiving IFC commit in any app (Revit, AutoCAD, Rhino, Grasshopper) leads to bad positioning. The model loses it’s original X,Y,Z.
Example 1
Receive in Rhino from Tekla (position is good):
Receive in Rhino from IFC (obtained from Tekla) (position is bad):
Example 2
Receive in Revit from Tekla (position is good) (don’t look at strange cross-sections – it’s another problem 
):
Receive in Revit from IFC (obtained from Tekla) (position is bad):
, and currently, when receiving we just take it’s raw mesh representation.
