摘要
创立了一种以表达式来表示技术尺寸的标注方法,以取代尺寸线的标注方法,这样可以简化表达方式,扩大表达功能、改革工程技术语言,利于人们读图、制图和使用计算机绘图。表达式尺寸标注法便于计算机记录、储存、传输、绘图并简化它的程序编制和信号输入,从而加速计算机在工程设计中的应用和发展,使人从繁琐的制图中解放出来,缩短设计工期,加快生产的发展。
To meet the needs of computer-based plotting and engineering pattern simplification, a method the combinatory dimensioning expression for pattern simplification is found. It is ble to simplify program input for computer-based plotting, to reduce labour intensity, to horten the period of engineering design and to bring the advantages of high speed and accurate ?or computers into play.The drawing will be more brief and clear.The combinatory imensioning expression and its usage rules are expounded.
