三、CAD系统的类型 CAD系统按其功能大致可以分为三种类型: 1.会话型:它是通过以上介绍的光笔进行时话。用光笔图形显示器通过人机对话修改计算内容和图形,直至获得预想结果。 2.试行型:它是通过软件进行修改。对设计结果和图形,使用者可以通过软性的输入进行修改和重新设计,直至获得预想结果。 3.信息检索型:这种CAD系统适用于设计
Third, the type of CAD system CAD system according to its function can be broadly divided into three types: 1. Conversational: It is through the light pen described above time. Use the pen graphical display to modify the calculations and graphics through human-machine dialogues until the desired result is obtained. 2. Trial type: It is modified by software. For design results and graphics, the user can modify and redesign through soft input until the desired result is obtained. 3. Information Retrieval Type: This CAD system is suitable for design
