FreeCAD is a versatile, open-source parametric 3D modeling software created for the purpose of designing tangible objects in various sizes. Its parametric modeling feature enables users to easily revisit the model's history and alter its parameters, facilitating design modifications. With FreeCAD, you can create constrained 2D sketches that serve as foundational elements for constructing additional objects. The software encompasses numerous components that allow for the adjustment of dimensions and the extraction of design specifics from 3D models, aiding in the production of high-quality, ready-to-use drawings. As a cross-platform tool compatible with Windows, Mac, and Linux, FreeCAD offers extensive customization and extensibility options. It supports a wide array of open file formats, including STEP, IGES, STL, SVG, DXF, OBJ, IFC, DAE, and many more, which enables smooth integration into various workflows. Designed to accommodate diverse applications such as product design, mechanical engineering, and architectural projects, FreeCAD caters to a broad audience. Regardless of whether you are a hobbyist, an experienced CAD professional, a student, or an educator, the user-friendly interface of FreeCAD ensures that everyone can find their place within the software. Embracing the community-driven development, FreeCAD continues to evolve, incorporating user feedback to enhance its functionality.
