@driven said: have you tried scaling a copy to see exactly what is lost? it may not be as bad as expected... just a thought john The cameras, and the textures UV.

thanks for passing by I've been told geo-wrml can support georeferencing data, but I'm not sure sketchup can output such a file format. I just got DXF (supposed to contain georeference data but I haven't any soft supporting that so I can't be sure) and have been asked to export my model in wrl format WITH the supposed georeference data, in order to be imported in a big database under SupportGIS, a german version of GIS soft. It's the first time I'm asked such a request so I'm a total newbie in this field...
