Hi,

Many thanks for you help. Unfortunately, still I can't display. v.info 
shows bad region limits (see below). Could the mistake be about bad 
region settings while importing?

Thanks again,

Roman



import process follows

g.region n=45N s=37N w=10W e=5E

v.in.dgn - all defaults accepted
This outputs a lot of warnings about complex element header ignored, 
complex elements parts written

Next I run v.support - all defaults accepted

Editing category file I have found some category strings have problems 
with tilde (system locale is spanish), but this seems not to be related 
with failed attachments

As you can see, region limits are somewhat shocking

funny, it isn't? ;-)

After this, d.vect still shows nothing


Running v.llabel doesn't help

I have not run v.alabel since v.info says there are no areas.

Best regards,

Roman
