Transitioning from ArchiCAD to SketchUp

Good day everyone! May I get some advise on how to Transfer files from ArchiCAD to SketchUp?
We tried to convert to .DWG to .SKP since sketchup do not have a direct import/export support to ArchiCAD.

But some of the lines and models are missing.

You can open your Archicad model in a 3D view and save it from there directly as a SketchUp (.skp) file.
