全局编辑命令在PCB设计中的应用

Application of Global Editing Command in PCB Design

PCB设计中的全局编辑(Global Edit),是指先通过查找相似对象,找出所有属性相同的图件(元件、封装、文字、焊盘和铜模线等PCB设计中所有能编辑的对象),然后采取类似于对单个图件的编辑操作,来对所有属性相同的图件执行相同的编辑操作。全局编辑能提高PCB设计效率,且在原理图编辑、元件图、封装图设计以及PCB设计时都可以使用。本文详细演示了全局编辑的操作步骤,对PCB设计初学者提高设计效率有指导作用。

Global Edit in PCB design refers to finding all drawings with the same attributes(components,encapsulation,text,pad,copper mold lines,etc.)by searching for similar objects,and then taking editing oper ations similar to those for a single drawing to hold all drawings with the same attributes,which makes the same editing operation.Global editing can improve the efficiency of PCB design,and can be used in schematic editing,component diagram,package diagram design and PCB design.This paper demonstrates the operation steps of global editing in detail,which is helpful for PCB design beginners to improve design efficiency.
