Hello,
sorry for crosspost..
I would like know your way to convert cad(dgn,dwg,dxf) data into usable
gis format. Is there some open source tool? Or we must use some
proprietarism? What of tools are now aviailable and what are your
expiriencies with them?
thx, karpi

You can load into GRASS with v.in.dwg. It is neither a fully open source
or fully proprietary solution (ie you violate the GPL if you distribute
it in binary form).

Karpi,
I am using opendesign's opendwg. I have registered as alliance member.
I am using dwg-s for educations reasons.
hello..
Ive account in oda too, (there was extremly hard work - because
of my .cz domain?, i do not know). But my mistake was, I downloaded
"DWGdirect" librairies: files:
DD_lnxX86.tar.gz, DD_lnxX86_3.4.3.tar.gz -- there some new version,
which do not work in grass. From their web:
"DWGdirect is the successor to our 2.X Toolkit & Viewkit libraries.
Rewritten from the ground up using C++, DWGdirect offers better
stability, more features, and simpler client integration than our 2.X
Toolkit & Viewkit libraries. The current version of DWGdirect supports a
wide range of database operations, contains full support for version
2005 DWG/DXF files, and contains vectorization support."
To compile into grass are neded old
"OpenDWG Toolkit/Viewkit libraries" file:
AD27LINX.TAR.GZ
unfortunatly download links from oda appears as "Forbidden (Invalid
URL)" -- only for me? i dont know.
Because of all that reasons seems almoast impossible to use this libs
for now.
So I found this:
http://dgnlib.maptools.org/
is their libs good? Im not a programmer, is there some way to try them
for me?

Hi!
I am sorry i have register on the web form of OpenDWG, but i still need send a
fax to them to download the toolkit for grass?
yes, you have to print all pages of "Associate Membership Agreement",
fill them where is possible, sighn every one page and fax it to US. Or
send by paper mail. And hope.

You can use a command line tool from OGR to convert from DGN to other formats. DWG/DXF not currently supported though. To get started using OGR, you grab FWTools from http://maptools.org/fwtools and you use the command ogr2ogr to convert. Let me know if you need more pointers. You may already have this tool as part of your GRASS install (?).

you can also use v.in.dgn - or is this not in the latest release? It works well for me.
