What is the purpose and functionality of FreeCAD? FreeCAD is a parametric 3D modeling software that is open-source. It allows users to design real-life objects of various sizes. The software includes tools for creating 2D shapes with geometry constraints, which can then be used as a foundation for building other objects. Additionally, FreeCAD supports multiple open file formats, such as STEP, IGES, STL, SVG, DXF, OBJ, IFC, DAE, and more, enabling smooth integration into different workflows. Furthermore, FreeCAD is compatible with Windows, Mac, and Linux operating systems.
