The tool box

The foundation of is its versatile tool box - the LucidObject library. Objects can be created through dialog boxes in or instanced by function calls in to build up the Digital Mock Up (DMU). The power of originates from this library which is growing constantly. The tool box holds a rich set of different object types to define geometry, material, media, motion, simulation, tasks, behavior, interaction and utility operation.

 The toolbox at a glance:
