Hello GRASS users
I am trying to import small files from ROOTS to GRASS by exporting
a ROOTS file to a .DBX format and then trying to use v.in.dxf
The .dbx files are small. Each map is a circle, broken into polygons each
of which is labeled by an integer. The lines are all snapped so things
should be simple. The .dbx file appears to contain all the information,
polylines, points (for the vertices), and text (for the attributes), but
when I run v.in.dxf, only a few of the attributes end up in the dig_attr
file.
Can anyone suggest a solution to this problem?
One problem we ran into was the fact that many .dxf files have data specified in blocks. v.in.dxf does not support blocks; so with autocad manual in hand(dxf spec.) we hand edited all the blocks out and converted them into entities. All seemed to work afer that.
Also we ran into a situation where the layer names specified by some packages are not consistent with grass/unix because of special characters. These were ignored by the system as well. Once we changed the names, all worked well.
