Alternatives to Autodesk AutoCAD for all platforms with Open Source License

  • FreeCAD

    FreeCAD is a general purpose parametric 3D CAD modeler. The development is completely Open Source (LGPL License). FreeCAD is aimed directly at mechanical engineering and product design but also fits in a wider range of uses around engineering, such as architecture or other engineering specialties. FreeCAD features tools similar to Catia, SolidWorks or Solid Edge, and therefore also falls into the category of MCAD, PLM, CAx and CAE.

    • Freecad is (as mentioned in the description) for 3D parametric CAD, and has no drafting functionality worth speaking of. Not a bad program, but certainly not an AutoCAD replacement. It has much more similarity to SolidWorks than AutoCAD Guest • Jan 2017 • 17 agrees and 6 disagrees Disagree   Agree
    • I use Freecad to design my 3D printing models. Guest • Oct 2015 • 8 agrees and 4 disagrees Disagree   Agree
    • Not bad for a free Software, but Workflow seems very antiquated and unneccessarily complicated. It lacks logic on available tools in different workbenches. There are much ways to get to your goal but every way takes really a lot of clicks and more of trial and error. Guest • Aug 2017 • 2 agrees and 2 disagrees Disagree   Agree
    • AutoCAD is a 2D drawing program, mostly used for architecture and structures. FreeCAD is 3D and aimed at mechanical engineers. They do different things. Guest • Feb 2018 Disagree   Agree
    • Because is an user friendly software and is free to use.Autodesk Autocad is very expensive eduardoortiz1Mar 2018 • 0 agrees and 1 disagrees Disagree   Agree
    • Not directly supporting DWG: needs a commercial/trial license of a file converter Guest • Apr 2017 • 2 agrees and 3 disagrees Disagree   Agree
    • Very good app, has many workbenches for different branches of engineering. It has a very helpful community forum. I really recommend trying it before looking for any other alternative. Guest • Jun 2017 • 0 agrees and 1 disagrees Disagree   Agree
    • FreeCAD is not a bad program, but it seems to lack functionality that AutoCAD provides. Currently FreeCAD seems to be in an early stage of development, and should probably not be considered for use in a professional production context, as a replacement for AutoCAD. Guest • Mar 2017 • 0 agrees and 2 disagrees Disagree   Agree
    • FreeCAD is a software for 3d parametric model, AutoCAD is not that. Guest • Sep 2015 • 0 agrees and 6 disagrees Disagree   Agree

  • LibreCAD

    LibreCAD (originally QCad then CADuntu) is an open source 2D CAD application for Windows, Apple and Linux. It is based on Qt, which is a leading cross-platform application and UI development framework. LibreCAD can read DWG files (and others) as of the latest Nightly build. It writes DXF files, but can also export SVG, JPG, PNG, PDF and other files.

    • No blockeditor or creating dynamic blocks. Guest • Feb 2018 Disagree   Agree
    • LibreCAD is only a 2d Drafting software while AutoCAD also has 3d modelling capabilities Guest • May 2016 • 6 agrees and 7 disagrees Disagree   Agree
    • Similar GUI like AutoCAD, and for 2D drawing, it is a perfect solution Guest • Jul 2017 • 1 agrees and 2 disagrees Disagree   Agree
    • If you know Autocad, you will learn librecad lightning fast. Guest • Jan 2018 • 0 agrees and 1 disagrees Disagree   Agree

  • OpenSCAD

    OpenSCAD is a software for creating solid 3D CAD objects. It is free software and available for Linux/UNIX, MS Windows and MacOS. Unlike most free software for creating 3D models (such as the famous application Blender) it does not focus on the artistic aspects of 3D modelling but instead on the CAD aspects.

  • NaroCAD

    NaroCAD is a fully fledged and extensible 3D parametric modeling CAD application. The goal of this project is to develop a fully fledged and extensible 3D CAD software based on the concept of parametric modeling of solids, comparable to well known solutions. These functionalities are interrelated through Model Associativity and are exposed through a GUI. The general usability specifications like saving, importing are described in General functionality specifications .

    • Discontinued The project is no longer developed. Last version, 1.8.8, released in December 2014, can be still downloaded from the official website.

  • ImplicitCAD

    ImplicitCAD is a programmatic CAD program, implemented in Haskell. Unlike traditional CAD programs, programmatic CAD programs use text descriptions of objects, as in programming. Concepts like variables, control structures and abstraction are used, just as in programming.

  • Archimedes

    Archimedes is a free and open source CAD (Computer Aided Design) software. It is a robust system built over Eclipse’s Rich Client Java Platform fully based on plug ins. This means it is easily extensible but also has a pretty thin core that allows you to select the features you need and drop the other ones easily.

    • Discontinued No ongoing development, but the application is still usable.
