早在50年代末期,数学计算机的商业应用就影响了几乎所有的工程部门。因此,一些计算机首先被用于解决复杂的工程设计问题。从广义上说,计算机辅助设计(CAD)是指:“从确定满足市场需要的产品特性,到列出这一产品应如何设计、制造,测试及环境保障(Field supported)等详细说明、整个过程都由计算机来帮助。”到60年代后期,围绕着集成 As early as the late 1950s, commercial applications of mathematical computers affected almost all engineering departments. Therefore, some computers were first used to solve complex engineering problems. In a broad sense, CAD refers to: “From specifying the features of a product that meets the needs of the market to specifying how the product should be designed, manufactured, tested, and supported by the field, the entire process All helped by computers. ”By the late 1960s, integration was around
