FreeCAD: Parametric 3D Modeler for Mechanical Engineering
An open-source 3D modeler for mechanical engineering design, allowing sketching of 2D shapes and building solid 3D objects with features like part modeling, assembly, drafting, and finite element analysis.
What is FreeCAD?
FreeCAD is a free and open-source parametric 3D computer-aided design application. It is intended for mechanical engineering product design but also expands to a wider range of uses around engineering, such as architecture or electrical engineering. FreeCAD features tools similar to Catia, SolidWorks, or Solid Edge.
FreeCAD allows users to sketch geometry constrained 2D shapes and use them to build solid 3D objects. Assembly modeling allows you to build assemblies by stacking parts. It includes many workbenches out of the box, allowing finite element analysis, gear design, and more. FreeCAD features parametric modeling meaning you can easily modify your design by going back into your model history and changing its parameters.
Some of the key features and capabilities include:
- Part modeling tools like pad, pocket, chamfer, and more for building parametric 3D parts
- TechDraw workbench for generating 2D drawings from 3D models
- Assembly modeling for building assemblies out of individual parts
- Finite element analysis workbench for structural and thermal simulation
- Rendering workbench for generating photorealistic images
- Arch workbench for architectural and BIM (Building Information Modeling) applications
- Sheet metal design tools
