SKP -> OBJ -> DGN
NOTE: This workflow used SketchUp 6 and Bentley Architecture XM. Subsequent versions of either application may have better (or worse) performance using native SKP (h/t to SF).
There may be situations during the design process where importing SketchUp models into Microstation is necessary. For example, you may want to search Google’s 3D Warehouse for context buildings that you can reference into your Bentley Architecture model for a context rendering of the site. The best way to go from SketchUp to Microstation is through .OBJ. OBJ is the Lightwave file format and seems to be very material/texture friendly. Microstation has no trouble digesting the SketchUp assigned materials and importing them if the correct settings are applied. Follow the directions below to get (most, if not all) of the correct textures and scale.
