The paper introduces an approach towards modeling and validation of mechanisms in the conceptual design phase applying virtual reality techniques and kinematics simulation. The presented system allows to interactively assemble mechanisms and to experience its behavior within the same process. The described approach incrementally builds kinematic chains reducing stepwise degrees of freedom. Kinematics is expressed in terms of geometric constraints, which are solved in real-time during interaction with the virtual prototype.
