About model and data exchange with 3rd party solutions: Revit, Solibri, dRofus, Bluebeam, structural analysis solutions, and IFC, BCF and DXF/DWG-based exchange, etc.
Is there a way to import a DWG that has a lot of those survey points as point objects in the right height into Archicad. I want then to export the x,y,z coordinates to create the mesh from survey points.
I have to avoid using Autocad to export the coordinates.
If you open the 3D DWG as an object (CTRL + SHIFT + O), you might get a 3D script with the coordinates. You just need to convert these to the XYZ format after with a text editor.
Maybe someone who has more experience importing XYZ files can help out there.
Over here in North-Holland NL everything is flat, so I draw terrain with slab tool
