About FreeCAD

Engineers, students or educators will definitely appreciate FreeCAD for the rich functionality it has to offer. This 2D and 3D design application lets you create assemblies of mechanical parts and manipulate them however you want. The best part is that FreeCAD comes with motion simulation capabilities, which can help you see how your assemblies will behave in real life, if they will perform properly or fall apart.

The software comes with various 2D and 3D drawing tools. You can create parts from scratch, by starting from basic solids, like cylinders, cones and so on. What's more, FreeCAD lets you connect your parts with joints, constraints, contacts, motors, actuators, springs, dampers and much more. This gives you the possibility of creating complex a complex machinery piece by piece.

Besides constructing a machine, you can also take advantage of FreeCAD's motion simulation capabilities to see how your creation would work. You can opt for open or closed 3D loops, in which the software will perform a full Multibody Dynamics Analysis on your assembly. The best part is that FreeCAD uses real-life physics, including Newton's laws, to predict your construct's motions.

The software can provide you with a vast array of information, in the form of plots and tabular outputs, to help you study your mechanism's dynamics. You can find all sorts of useful data, including displacements, velocities, accelerations, forces, torques and much more. You will be able to see what forces are applied to each individual joint, actuator, spring or any other part and figure out where you need to work to improve your mechanism.

FreeCAD Features

Build complex mechanisms from scratch


You can edit basic solids to build complex machines. The software provides you with various connectors, including joins, actuators, motors, dampers and more.

Motion simulation


Once your machine is built, you can let the software simulate how it would work in real life. You can start open or closed 3D loops, to see how your machine will move with the given connectors.

Multibody Dynamics Analysis


By using real-life physics, the software is capable of predicting your mechanism's motion with a high degree of accuracy.

Automatic solution computation


After you build and simulate your mechanism, FreeCAD can provide you with kinematic, quasi-static and dynamic solutions for a time interval of your choice.

Rich data output


To help you study your mechanism's dynamics, the software can provide you with a huge amount of data, about displacements, velocities, accelerations, forces, torques and other aspects, in the form of plots and tabular outputs.
