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...
