There are many types of open source software that are of interest to engineers. Here are a couple examples:
- Arduino Software Download
- An open-source electronic prototyping platform enabling users to create interactive electronic objects.
- SciPy
- Open-source software for mathematics, science, and engineering
- Open Source Hardware Association
- OSHWA’s primary activities include hosting the annual Open Hardware Summit and maintaining the Open Source Hardware certification, which allows the community to quickly identify and represent hardware that complies with the community definition of open source hardware.
- FreeCAD
- Open source parametric 3D modeler made primarily to design real-life objects of any size.
- QCAD
- 2D CAD for Windows, Linux, and Mac
- GrabCAD
- Open and enterprise-ready software platform for additive manufacturing.
- BRL-CAD
- 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, and geometry libraries for application developers.
- 3D ContentCentral
- 3D ContentCentral is a free service for locating, configuring, downloading, and requesting 2D and 3D parts and assemblies, 2D blocks, library features, and macros.
This website from Open Engineering has a list of many other open source tools.
