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.
See for example
- 6 of the Best Free Linux CAD Software
- The LUnIx Linux CAD Links: Extensive list of more than 50 alternatives with their licence type.
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.
Check out these 2Doptions.
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.
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.
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.
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:
- Closest Autocad equivalent is Bricscad.
- Second place goes to ARES Commander and CorelCAD.
- 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.
