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!
