Computer Graphics System Dedicated to Assembly-Layout Kinematic Diagram of Mechanism Assembly

Basic kinematic elements as graphic primitives are provided and the supplementary functions,such as interactive layout of mechanism,editing the primitives and accurate positioning the cursor are implemented that can help the mechanical engineers or teachers to draw the kinematic diagram conveniently and efficiently.Kinematic dimensions are saved as the main parameters of graphic primitives and presented on the screen directly,the user may modify them easily.
