Geographic Information Systems Stack Exchange is a question and answer site for cartographers, geographers and GIS professionals. It's 100% free, no registration required.

I would like to know if there are any free (for commercial use) software packages that roughly correlate to the functionality in AutoCAD Map. Specifically, I am looking for something that is:

  • Commandline based.
  • Opens .dwg and possibly .dgn files.
  • Can generate world files for raster georeferencing.
  • Optional: Civil 3d functionality such as alignment and profile generation.

Draftsight http://www.3ds.com/products/draftsight/draftsight-overview/

or even better

DoubleCAD http://www.doublecad.com/Products/DoubleCADXTv3/tabid/1100/Default.aspx

That's great! I had no idea about doublecad. –  WolfOdrade Dec 17 '10 at 16:46
    
Thanks! I have been evaluating both of those, and I have found that Draftsight runs smoothly and can open more of my large files. –  jvangeld Dec 20 '10 at 17:46
    
Glad to help and you got the result you wanted –  Mapperz Dec 20 '10 at 18:04

Another project, sourceforge.net/projects/librecad derivated from QCAD –  ThomasG77 Jan 1 '11 at 23:34
    
Thank you Mapperz. I can't wait to try this out!! –  Dano Aug 13 '11 at 16:16

You can have a look in GvSIG (OADE version), it starts to have good build-in tools for CAD, so :

  • it has a command line tools to edit every points (with some topology functions)
  • it opens .dwg, .dxf and .dgn files
  • it generates world files for raster georeferencing
  • it integrates like Kosmo, Sextante and now Grass for the OADE version so you can make profile

GvSIG exists in two flavour and both are opensource : original and OADE (derivated from original and with some extra features)

Regarding the others tools I discover with Mapperz link, you will just have to use GvSIG + a true CAD tool.

Do you choice :)

Thanks, Thomas, I didn't realize that GvSIG had all of those features. –  jvangeld Dec 20 '10 at 17:45

You should try Kosmo http://www.opengis.es/ it reads DXF/DWG (version 2000 only) and DGN you can georeference rasters and has some CAD functionalities profile generation can be done with Sextante it is shipped with Kosmo. It is open source
