Hi Joe,

>From time to time I also try to export files from Microstation 
(Intergrapgh platf) to Grass. My experience is the same as yours. I am 
indeed afraid that you will need to do the labeling of the vectors by 
hand using v.digit or by adapting the vectorfiles using the ascii version 
of the vector. It seems that the dxf format only understands different 
layers. My different layers are imported as different files an that is 
the only sort of "labeling" I recognised until now. In fact I had the 
same experience using dxf files from AutoCad. The problem of the 
declaration of a polygon (in a dxf) as an area in Grass is as far as I 
can see also not possible. In a way I hope someone can overrule these 
remarks. So if you should receive further info about this please let me know!
