I have a georeferenced DWG-file in a national projection and want to import it into SketchUp pro 2015 without loosing the georeference. My workflow so far was to import it into QGIS, check it's location using OpenLayers and save it again with the projection EPSG:3857 (Web Mercator), open a new SketchUP-file, set the geo location for the project and import the DWG file. This dosn't work.
The DWG import is placed somewhere. I don't want to georeference it again with the Google image, because this would cause a big lack in precision.
Does anyone know a solution, maybe a file format that works, or any workaround?
