FreeCAD: Your own 3D parametric modeler

Key FreeCAD Features

Made to build for the real world

FreeCAD is made primarily to design objects for the real world. Everything you do in FreeCAD uses real-world units, be it microns, kilometers, inches or feet, or even any combination of units. FreeCAD offers tools to produce, export and edit solid, full-precision models, export them for 3D printing or CNC machining, create 2D drawings and views of your models, perform analyses such as Finite Element Analyses, or export model data such as quantities or bills of materials.

A powerful solid-based geometry kernel

FreeCAD features an advanced geometry engine based on Open CASCADE Technology. It supports solids, Boundary Representation (BRep) objects, and Non-uniform rational basis spline (NURBS) curves and surfaces, and offers a wide range of tools to create and modify these objects, including complex Boolean operations, fillets, shape cleaning and much more.

A wi(l)dly parametric environment

All FreeCAD objects are natively parametric, meaning their shape can be based on properties such as numeric values, texts, on/off buttons, or even other objects. All shape changes are recalculated on demand, recorded by an undo/redo stack, and allow to maintain a precise modelling history. Properties of one object can drive the value of properties of other objects, allowing complex, custom parametric chains that could only exist in your wildest dreams. New parametric objects are easy to code.

Assembly solutions for every need

FreeCad offers a bunch of great assembly workbenches with different solvers and even solver-free workflows made by the community to assemble the parts you create. There are also some really interesting solutions outside of the workbenches. The project of having an internal assembly workbench that has been going on since day one didn’t happen due to some problems with the existing solvers, but now we have Ondsel Solver. And now with version 1.0 you have an assembly workbench right out of the box.

Also for architects

Until version 1.0, FreeCad had a built-in Arch workbench and an external BIM workbench added on top of that. With version 1.0, both of them have merged and now we have a built-in BIM workbench. Now you can do your building and construction related projects right out of the box.

Python everywhere

While the FreeCAD core functionality is coded in C++ for robustness and performance, large parts of the external layers, workbenches and almost all the communication between the core and the user interface is coded in Python, a flexible, user-friendly, easy to learn programming language. From Python code, you are able to do just anything in FreeCAD, from simple one-line commands in the integrated Python console to recording macros, coding your own tools up to full custom workbenches.

File formats frenzy

FreeCAD allows you to import and export models and many other kinds of data from your models such as analyses results or quantities data to dozens of different file formats such as STEP, IGES, OBJ, STL, DWG, DXF, SVG, SHP, DAE, IFC or OFF, NASTRAN, VRML, OpenSCAD CSG and many more, in addition to FreeCAD's native FCStd file format. Add-on workbenches can also add more file formats.

A parametric constraints-based 2D sketcher

FreeCAD features a state-of-the-art Sketcher with integrated constraint-solver, allowing you to sketch geometry-constrained 2D shapes. Sketches are the main building block of FreeCAD, and the constrained 2D shapes built with it may then be used as a base to build other objects throughout FreeCAD, be it either with the dedicated Part Design workbench or any other workbench.

A large (and growing) multi-specialty ecosystem

FreeCAD offers dedicated workbenches for a variety of purposes such as CSG modeling, simple 2D CAD drafting, NURBS surfaces, architectural or BIM modeling, 3D printing, CAM and CNC, point clouds, working with OpenSCAD files, designing industrial robot trajectories, doing Finite Element Analyses, and much more. FreeCAD also provides easy tools to install and manage add-on workbenches and macros developed by the users community.

Developed by a community

FreeCAD is made for everybody, by everybody. It is developed and maintained by a community of developers, users, moderators, translators, all united by their wish make FreeCAD a free and powerful tool. There is no commercial aim behind decisions being taken, no urge to make you upgrade your version of FreeCAD or to corner you into a specific workflow or ecosystem. FreeCAD and the files and data you produce with FreeCAD are truly yours, forever.
