CAD stands for Computer Aided Design or Computer Aided Drafting. CAD was developed in the early 60s. Today it is the premier way to design, develop and optimized products.
FreeCAD is a parametric 3D modeler made primarily to design real-life objects of any size. Parametric modeling allows you to easily modify your design by going back into your model history and changing its parameters. FreeCAD is open-source and highly customizable, scriptable and extensible.
LibreCAD is a free Open Source CAD application for Windows, Apple and Linux. Support and documentation is free from our large, dedicated community of users, contributors and developers. You, too, can also get involved!
It is free software and available for Linux/UNIX, MS Windows and Mac OS X.
Archimedes is a free and open source CAD (Computer Aided Design) software. It is a robust system built over Eclipse’s Rich Client 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.
Free CAD software. nanoCAD – professional and simple CAD software, with full *.dwg support.
BRL-CAD is a powerful open source cross-platform solid modeling system that includes interactive geometry editing, high-performance ray-tracing for rendering and geometric analysis, a system performance analysis benchmark suite, geometry libraries for application developers, and more than 30 years of active development.
Blender is the free and open source 3D creation suite. It supports the entirety of the 3D pipeline—modeling, rigging, animation, simulation, rendering, compositing and motion tracking, even video editing and game creation.
Onshape is a modern CAD system used by thousands of companies worldwide. Onshape eliminates design gridlock and helps engineers do their best work.
ARRIS is the most highly customizable CAD software available. Sigmac source is available for the current version of ARRIS. Any customizations must be compiled on the same version of ARRIS in which they are run. The basic idea behind open source is very simple. When programmers can read, redistribute, and modify the source code for a piece of software, the software evolves. People improve it, people adapt it, people fix bugs. This rapid evolutionary process produces better software than the traditional closed model.
