It's just informational
If someone is looking for a 2D CAD application I can suggest one which is working quite well
http://www.3ds.com/products/draftsight/download-draftsight/
Linux version is still beta, you need to convert .deb or .rpm package, additionaly download "nas-1.9.2-2-i686.pkg.tar.xz" and extract the following files in the /usr/lib directory:
libaudio.a
libaudio.so
libaudio.so.2
libaudio.so.2.4
The rest of dependencies are installed automatically from our repository
I was able to download and run the application without sending any personal data, but they say activation is required
If you know any alternatives to this one, or 3D applications please post information here
