Georeferencing - Survey Point Data and 2D CAD

[Aaron Bourgoin]

There is a thread with a similar question/topic, but it is locked.

When exporting 2D CAD from model space with a translator that references the survey point (not the project origin), does the georeferenced Northing and Easting put the drawing into the proper spot in a GIS system? The parameters I mean are listed as IFC parameters. If it's only that, then how do we communicate with disciplines that work exclusively in 2D CAD?

Operating system used: Mac Intel-based Sonoma

When exporting in real world coordinates, the survey point location will become the origin of the DWG file and rotated to align north with the Y axis. The translation will depend exclusively in the survey point coordinates above in the image you sent, not in the Map coordinates you introduced below.

That's what I was afraid of. Can we turn this into a wish for a "smarter" survey point or one that offers to use 'real world' northing and easting points?

Since the world is round and Archicads drawing plane flat only exact one point can be exported into a GIS format. 
Archicad, Revit Allplan and VectorWorks do not support GeoCoordinates. 
I therefore only coordinate 2 to 3 reference points within my file as a reference to Planers that need real coordinates. 
My file stays close to Archicads origin, not northed, unturned in the main direction of the design. Shall others do their Job. I don‘t have any advantages of geo-coordinates within my process….

 Of course my workflow doesn’t justify the half baked functionalities of archicad

I was trying the use the "new" survey point but it seems it dosent work in the same as before. Before i could set the surveypoint in AC 0,0,0 and "say" it was the coordinates 100,000,000 and 100,000,000 in real world, so when i exported IFC my origin in AC would the the real worl coordinate. Now it seems the survey point only allows to change the origil (null point) to another place. Or im missing something here?
