LX-Viewer will allow you to open, view and print DWG or DXF files, typically used in CAD related technical drafting. You may zoom and pan the drawing normally and save to DWG or DXF from AutoCAD v2.5 to 2002 +BMP, PNG and SVG format
Does not work - bundles an i386 lib (ad2.a) and attempts to link to it. The ad2.a library is not open source, and simply wont work on modern systems.
It really is NOT an open source project. It can not be used without a library from the very misleadingly named "OpenDWG", which will cost you hundreds of dollars for a membership unless you can get the educational membership and that requires filling out and mailing/faxing two long forms with an extremely restrictive license.
