Development of mechanism construction CAD tool and the motion animation

We have been created several kinds of mechanism construction system for over fifteen years. The first applied 2D graphics to show mechanical element on the screen and we aimed at the combination of elements. After reviewing of these four systems, we present newly developed Mechanism Construction Tool. In the system models are created by assigning parameters for the primitives and they are located on the 3D space, combined with the other models. The accomplished mechanism structure is shown in the graphic screen by moving them in real time and the structure data are transmitted to the OmegaSpace VR environment development tool through internet communication. In this paper, we describe the objectives of the CAD by explaining its feature, basic structure, functions and application examples and the expansions for the future development.
