Giorgos,

GRASS distinguishes between points (single coordinates) and lines (multiple
coordinates by expecting them to live in different directories and map
layers. Point coverages such as wells should go into the $LOCATION/site_lists
directory, or, if they have variables attached, into the RIM or other
database engine you use. Lines go into vector maps in the $LOCATION/dig*
directories, again with variables in RIM or other database.

Your error messages flag up the fact that you are trying to put points into
a vector map. Solution: either digitise points and lines separately, or edit
the DXF file to extract all points into a site_list.
