在计算机技术的冲击下 ,工程设计中对产品模型的图示发生了重大的变化 ,其发展对工程图学课程产生了深远的影响。制图方式的自动化又带动了工程或产品设计的自动化 ,使得设计与制造之间将不再有单独的制图阶段
Under the impact of computer technology, the design of the product model in the project design has undergone major changes, and its development has had a profound impact on the engineering graphics. The automation of cartography also drives the automation of engineering or product design so that there will no longer be a separate cartographic phase between design and manufacturing
