This role allows manufacturing engineers and constructors to simulate assemblies or mechanisms. Kinematic joints, defined in the design phase, enabling understanding of the design and are easily re-used in assembly views, regardless of the complexity of the product structure. Functional validation and validation of mechanisms can be implemented interactively or by launching kinematic and dynamic scenarios. Data such as accurate collision analysis, distance calculation, geometry traces, and swept volumes of moving parts are shown in animations and video captures of mechanisms in different simulation phases.
