摘要
以机构基本运动要素作为基本图元 ,并辅以可视化的图元绘制、编辑和定位技术等设计的机构运动简图计算机组构式绘图系统 ,有效地提高了机构运动简图的绘制效率 同时 ,系统根据机构运动规律与机构运动尺寸密切相关的特点 ,选择机构运动尺寸作为图元的主要几何参数并通过窗口直接显示图元的参数信息 。
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.
