For beginners in mechanical engineering, it seems difficult to suppose motion of each element that composes a certain mechanism. As one of the solution of this problem, we have proposed a computer assisted instruction (CAI) system for simulating 3-dimensional mechanism construction which can be used either for presentation by teachers or for self-learning to see motion of any mechanism. In order to have an experience in constructing mechanism, each student operated the system with one's own terminal. The description of students' reports submitted after the class suggests that they can understand a number of parameters are required to design even though a simple mechanism through the system. Therefore, the proposed system can be effective to give the motivation for studying mechanical engineering.
