【摘要】 本文介绍了在Apple-Ⅱ微机上开发的简单断面型钢CARD绘图软件。通过建立绘图指令模拟子程序模块和绘图基本功能子程序模块,使廉价的Apple-Ⅱ微机也可用于型钢孔型图的绘制。该软件系统由各种简单断面型钢孔型的绘图程序构成,采用汉字显示人机对话方式,操作方便,绘图迅速,可以提高孔型设计者的工作效率。更多还原

【Abstract】 This paper describes the development and application of CARD(Computer aided roll pass design)drafting software used in simple section bars steel with Apple-Ⅱ microcomputer. Through establishing subprogram models of drafting instruction simulation and basic drafting function, the cheaper Apple-Ⅱ microcomputer can be used to draft roll pass figures. The software system is built of drafting programme for all simple section bars, roll. Since man-machine dialogue and Chinese-Display are used in this system, operating and drafting become convenint and quick.This system can increase working efficiency of roll pass designer.更多还原
