How do i convert .dwg to .dxf using free software(as in freedom) only (webapps are ok) ?

share|improve this question
@Rinzind that is for viewing whereas this is for converting so i can use .dxf files in qcad or FreeCad . – Alaukik Jun 16 '11 at 17:21

Teigha File Converter

This is 'free as in beer' software however I have no other alternative.

There is a DEB package for installing on Ubuntu 32-bit.

However for Ubuntu 64-bit users, like myself, you are relegated to downloading the Windows installer and using Wine to install it. Note that you will need Wine version >= 1.3.5 otherwise MSVC++2010 installer crashes.

I have updated the question to include the type of free software. I think limiting this question to only libre software is too narrow for the topic so you should allow some leeway for other suggestions. – Cas Sep 15 '11 at 14:16
If you think this question is too narrow and think AskUbuntu should have information about non-free software that converts .dwg to .dxf, you can ask and answer your own question about that, and post a comment in this question linking to it. This answer, as it stands, does not actually attempt to answer the question that the OP asked. – Eliah Kagan Jun 1 '12 at 3:16
On Teigha site they have included 64-bit deb file, but of poor quality. Do you have any experience with it? – VRR Apr 12 '15 at 9:40

Never tried the following myself. Just searched some.

it cannot convert the files from newer versions of autocad and it's last revision was in 2002. – Alaukik Jun 16 '11 at 18:08

There is Draftsight, currently in beta on Ubuntu. I've used it on Windows and it look pretty good for a free (of cost) app

Why the -1? DraftSight has a free version that allows conversions of that kind – ringø Oct 22 '13 at 8:16

Just use Autocad's webapp:

Upload your .dwg (you can even view or edit) then download as .dxf.
