FreeCAD

FreeCAD is an open-source parametric 3D modeler designed for creating real-life objects of any size. Its parametric nature allows for easy design modifications by adjusting past parameters. You can sketch 2D shapes and build 3D objects, and also extract design details from 3D models for production-ready drawings.

This powerful and evolving modeler is suitable for many professional and technical tasks. With its version 1.0 release, FreeCAD offers enhanced stability and usability. It provides complete control without licensing fees or vendor lock-in, making it a cost-effective and adaptable solution. Whether you are prototyping, 3D printing, designing furniture, or learning CAD, FreeCAD supports your creativity with no sign-up, paywalls, or restrictions.

FreeCAD is a multiplatform (Windows, Mac, Linux) and highly customizable software. It supports numerous open file formats like STEP, IGES, STL, SVG, DXF, OBJ, IFC, and DAE, enabling seamless integration into your workflow. It is designed for product design, mechanical engineering, and architecture, welcoming hobbyists, programmers, experienced CAD users, students, and teachers.

Key features include modern Finite Element Analysis (FEA) tools, experimental CFD, dedicated BIM, Geodata or CAM/CNC workbenches, and a robot simulation module. FreeCAD is a versatile toolkit for general-purpose engineering.
