Here's how it works:
  1. Anybody can ask a question
  2. Anybody can answer
  3. The best answers are voted up and rise to the top

Just that. By good I mean something at the level of SolidWorks, AutoCAD, or similar. This is a complete limitation for me (and many others) to use Ubuntu.

Please specify what you need the CAD application for. There are plenty of open and commercial solutions available. – Takkat Feb 18 '11 at 8:02
Are you looking for a free one? – Joril Feb 18 '11 at 8:06
@Takkat autocad is usually for architecture – Elzo Valugi Oct 24 '13 at 19:15

See for example

Not exactly the same as Solidworks or Autocad, but it really depends on what you are going to do. Reviews says that many free software do have good quality, but unfortunately that's really subjective.

+1 for the links esp. tech-edv – Takkat Feb 18 '11 at 12:02
Can you quote the contents of the links to prevent link-rotÉ – raphael May 11 at 15:36

You could try FreeCAD or BRL-CAD or some of the other floss alternatives.

DraftSight is a DWG files 2D editor and it has similar environment as AutoCAD. It is free of charge but is not Open Source.

Note: for the moment it only works for 32bit systems (oct.2013) :( – Elzo Valugi Oct 24 '13 at 19:14
No, it works nicelly in my 64 bit system, but installation was a pain (I had to hunt all the i386 libraries that it need). – Javier Rivera Oct 25 '13 at 10:12
Draftsight is very close to Autodesk Autocad, I have a very good use of it – Ale Jan 11 '14 at 14:32


It is a good and professional CAD Solution. It is available for Ubuntu. Since it is not OpenSource you can download a free trial version, it will works just like the full version for a period of 30 days. Require registration before.

Downloaded from Ubuntu Software Center on 14.04 LTS 64bits. Worked fine, but I just needed to view the content. – Telmo Pimentel Mota Aug 15 '14 at 17:37

Check out these options.

LibreCAD is a free Open Source CAD application for Windows, Apple and Linux.LibreCAD is available in the Ubuntu Software Center. LibreCAD is an application for computer aided design (CAD) in two dimensions (2D). With LibreCAD you can create technical drawings such as plans for buildings, interiors, mechanical parts or schematics and diagrams.

DraftSight is the only native software running on Ubuntu compatible with DWG files - it's 2D only (can view 3D files but not create them), sort of an equivalent to AutoCAD LT.

If you want to spend money then

Bricscad is a lot more powerful, has ACIS modeling just like AutoCAD (Pro version) and its Platinum version has even parametric modeling.

thank you @karel – Aatish Sai Oct 25 '13 at 10:02
Please do not post duplicate answers on different questions. It just creates more work for the moderators. If the questions are so similar that the same answer works on each, then the later of the two is likely a duplicate and should be flagged as such. – RolandiXor Oct 26 '13 at 17:51
Ok. Will keep in mind from next time – Aatish Sai Oct 27 '13 at 2:15


Bricscad is a 2D CAD and 3D direct modeling. This software have three licenses models offering different prices. You can download a free version without license key for a 30 day trial period. This version is received via an email.

Google sketchUp

Ok so its not strictly speaking a native Linux application. But it runs under Wine. Is very powerful and very easy to use and most of all is completely free.

"At level of Autocad" means commercial software. Best commercial software. I used many CAD programs in both Windows and linux, and my assessment for linux is like this:

  1. Closest Autocad equivalent is Bricscad.
  2. Second place goes to ARES Commander and CorelCAD.
  3. Third place goes to DraftSight Pro (because it got video card issues on nVidia cards).

Solidworks is NOT CAD, is PLM (product lifecycle management). Best equivalent for Solidworks could be Siemens NX. Others may say CATIA, but CATIA lost linux support back in 2008.
