机械CAD软件参数化绘图程序的专用函数编制

The special function compose of mechanism CAD software in parameterized drawing program

针对企业产品特征,开发专用的机械CAD系统,以实现基于设计数据驱动的参数化绘图,能够提高设计效率。以W indows为操作系统,VC++6.0为开发平台,AutoCAD为图形支撑软件,SCR命令文件为参数化绘图接口,基于桥式起重机参数绘图软件开发的高效率和模块化需求,对软件中大量使用的特征图形、标准符号进行专用函数的编制开发,以达到减少参数化绘图软件编程工作量的目的。

Aim at the characteristics of enterprise product, develop the special mechanism CAD system to realize the parameterized drawing based on the design data driving. It can save the manpower, material resource and financial capacity, attain the resuit of matter half work times. Takes Windows as the operation system, VC ＋＋ 6.0 as the developing platform, AutoCAD as the support software of the figure, the SCR （script） file as an interface of parameterized drawing. Based on the demand of high-efficiency and modularization for developing software of parametric drawing of bridge crane, compose and develop the special function of the characteristic drawing and standard symbol greatly used in software to decrease program workload of parameterized drawing software.
