Users can view forces and torques from joints, constraints, actuators, springs, dampers, applied forces and inertia. Acceleration data include transverse, centripetal and Coriollis accelerations. Data series available include linear and angular displacements, velocities, accelerations, forces, torques, momenta and kinetic energies. XY plots can be zoomed and set to equal scales. Users can study the mechanical dynamics in the form of plots and tabular output. Animation using the simulated data produces realistic dynamic behavior of the system. freeCAD performs full Multibody Dynamics Analysis on the assembly to predict the motion according to Newton's Laws. Both open and closed 3D loops are permitted.

The parts and connections define the structure, mechanism or machine of interest. The parts are simple 3D solids, which can be connected by joints, constraints, contacts, motors, actuators, springs, dampers, forces, torques or gravity. It is a freeware and can be distributed freely.įreeCAD allows users to create and manipulate assemblies of parts.

Assembly data are unchanged across platforms. The program runs on Windows, Linux PC, Macintosh PPC and other Unix's.

Educators, students and new engineers will find it ideal for the teaching and learning of geometry, kinematics, dynamics, vibrations, mechanisms, linkages, cams, machine design and physics. It is suitable for anyone interested in learning 3D CAD and Motion Simulation for free before using more sophisticated packages. FreeCAD is a basic 3D CAD with advanced Motion Simulation capabilities.
