Integrated version control along with straightforward management tools eliminates the expensive requirement for a separate PDM system, ensuring that you and your team always have access to the most current design data. Every alteration made by users is meticulously logged, allowing for a history of changes that can be reversed at any moment, thus offering limitless undo/redo options alongside a thorough audit trail. The option to branch and merge facilitates the simultaneous development of various product concepts. One of the standout features of SolidFace is its parameterization capability, which is utilized throughout all phases of design. 3D motion simulation benefits from this as it updates in real-time with any movement. Additionally, the software can simulate 2D mechanisms, allowing for analysis in either a 2D drawing space or within the 3D sketch environment. Furthermore, SolidFace provides direct access to an extensive online part library, boasting over 100 million part numbers sourced from numerous top manufacturers and distributors, as well as thousands of standards such as ISO, ANSI, DIN, NF, GB, and ASME. This comprehensive resource enhances the design process, making it more efficient and effective for users.

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 Due to QCad CE being built on the outdated Qt3 library, a port to Qt4 was necessary before further improvements could be made, leading to the temporary creation of CADuntu.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.
