LibreCAD is an open-source CAD software available for Windows, macOS, and Linux platforms without any cost. Users benefit from extensive support and documentation provided by a thriving community made up of users, contributors, and developers. The initiative began as an effort to integrate CAM functions into the community version of QCad for a Mechmate CNC router. Due to QCad CE being built on the outdated Qt3 library, a port to Qt4 was necessary before further improvements could be made, leading to the temporary creation of CADuntu. However, after a brief period, the community concluded that the name was not suitable and engaged in discussions to find a more fitting title, resulting in the adoption of LibreCAD. The transition of the rendering engine to Qt4 was a significant undertaking, and as a result, LibreCAD initially relied on the Qt3 support library. Ultimately, this port was completed during the development of the 2.0.0 series, thanks to the efforts of our chief developer, Rallaz, marking LibreCAD's evolution towards being completely independent of Qt3, except for the 1.0.0 series. This transformation not only enhanced the software's capabilities but also solidified its position within the CAD community.

This software is open-source and compatible with Linux/UNIX, Windows, and Mac OS X. Unlike many free 3D modeling tools like Blender, which emphasize artistic creation, this software is primarily focused on computer-aided design (CAD) functionalities. Therefore, it might be ideal for those intending to design 3D models of mechanical components, but it likely won’t suit your needs if you're aiming to produce animated films. OpenSCAD operates differently from traditional interactive modelers; it functions more like a 3D compiler that interprets a script file detailing the object to generate the 3D model. This approach grants designers complete authority over the modeling workflow, allowing for straightforward modifications at any stage of the process and supporting designs that can be defined by adjustable parameters, making it a powerful tool for precision engineering. Moreover, the ability to script models can significantly enhance productivity and repeatability in design tasks.

SOLVESPACE is an open-source parametric 3D CAD software released under the GPLv3 license, allowing users to design 3D components and create drawings through various operations such as extruding, revolving, or using Boolean methods like union, difference, and intersection. It also enables the modeling of 2D parts by allowing users to draw a single section and export it in formats like DXF, PDF, and SVG, while the 3D assembly feature aids in checking component fit. For those interested in 3D printing, parts can be exported in STL or other mesh formats compatible with the majority of 3D printers. Additionally, it supports the preparation of CAM data, enabling the export of 2D vector art tailored for waterjet machines or laser cutters, or generating STEP and STL files for integration with third-party CAM software for machining processes. The tool is particularly useful for mechanism design, utilizing a constraint solver to simulate both planar and spatial linkages, accommodating various joint types such as pin, ball, or slide joints.
