摘要
工程实际中,常遇到一些在已知图形材料中截取一个给定条件的图形以满足下料要求,节省不必要的材料浪费。如果用直尺+圆规的传统方法进行绘制,不仅效率低,而且精度也不易保证。AutoCAD中"scale"命令通常用于图形的放大和缩小,其"参照"功能很少有人会用到。本文通过实例,详细解释了"scale"命令中"参照"功能在破解上述难题中的应用,这对解决工程实际中一些特定条件下的下料问题找到了一条捷径,同时扩展AutoCAD使用范围有着积极的工程实际意义。
In engineering practice, it often encounters the condition that intercepting a graphics with given condition to meet the requirements of graphic material and save unnecessary waste of materials. If using the ruler and compasses traditional method, not only the efficiency is low, but also the precision is not easy to guarantee. The ＂scale＂ command in AutoCAD is usually used for graphics zoom-in and zoom-out, but few people can use its ＂reference＂ function. Through the actual case, this paper conducts a detailed explanation on the application of ＂reference＂ function of ＂scale＂ command in solving this problem, which is a shortcut to solve this problem, while has a positive practical significance in extending the application range of AutoCAD.
