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.

  • Thanks! I have been evaluating both of those, and I have found that Draftsight runs smoothly and can open more of my large files.

    There is Free Personal option for DoubleCad while you can only use DraftSight demo for free.

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

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.

This is a good plugin QAD for QGIS

https://plugins.qgis.org/plugins/qad/

which can be a good alternative to AutoCAD tools in the free version.

You have the command prompt and drawing tools.

as well as the other CAD tools available, about which you can read & watch below
