The drawing is moving around

[Anonymous]

I put an xRef in my worksheet page in original place like in Autocad so the imported drawing has correct coordinates. Then I started making plans in the Project map with xRef as a Trace underneath. Everything ok... But when I close the file and reopen it, my drawing in the Project map and xRef are dislocated a few hundred meters and are not aligned at the same time. Any ideas?
Does Archicad uses Gauss-Kruger or UTM coordinate system? I can't seem to find this info...

Robi:

One thing to try is to move the model (ArchiCAD) to the project origin (the model prefers to be there). The Trace & Reference from the Worksheet can then be dragged to align with the ArchiCAD model.

This is certainly a solution but in this case I would loose correct coordinations wouldn't I... Well if this continues I'll know what to do
Maybe I should report this behaviour to Graphisoft so they can look at it.. I mean it's shame not to use this.
