3d polyline terrain data from DWG to Archicad

[Anonymous]

Hello,
I have to get 3-d polyline terrain data into an archicad22-project (cant attach a dwg here... ). I dont want to use the points-to-.txt-method if possible, because of the amount of data. Also redrawing is too much work.
It should be possible to export the data as an IFC Site, but i dont know how to define the polygons as IFC-Site in autocad Map 3d 2018. I also got access to revit, but no experience.
Help would be much appreciated!

Afraid the only way we got anywhere a few years ago was indeed getting the coordinates into an .xyz text file to import.

If you have ArchiTerra, you can convert your dwg into a dxf and ArchiTerra can build a mesh for you from that. Pretty sure it reads 3d polylines.
