Coordinates | Absolute coordinates | Collaborate

Hello.

I need help with the project coordinates.

Situation
I have an AutoCAD drawing. (...ifc of the existing land and the planned road is also there) Everything is fine and correct with the coordinates. The building is located correctly.

And I have a file from an architect from ArchiCAD. I save it in DWG. When I insert this file into DWG, the building appears in a completely different place.

I need the building to be with the correct coordinates.

Other
I figured out how to move the entire building to the desired coordinates relative to the point (0;0).
But this is not the answer I need.

As far as I understand, "Survey Point" can help me. But I don't understand how to use it.

Like...
Road and landscape designers work in an absolute coordinate system, and they have no problem with the general (0;0).
Whereas architects have their own (0;0).

How can I move the (0;0) point of a project in Archicad so that the drawing is located at the correct elevations?

On the drawing in AutoCAD, I measured the distance to 0 along x and y from the known corner of the building.

In ArchiCAD, I plotted a straight line along x and a straight line along y from the known corner of the building.

I set "Survey Point".

In BIM, the coordinates are displayed correctly.
"Survey Point" does not work in AutoCAD.
