CadenceAllegro的Gerber导出步骤钻孔图的导出步骤：首先要给每一种VIA定义一个字母。
Manufacture\NC\Drill Customization。
在Symbol Characters里给每一个VIA定义一个字母，注意不能重复，其他数值禁止修改。
（如果在做PAD的时候定义过字母，那就只需检查一下是否有重复的。
）然后，选Manufacture\NC\Drill Legend。
一定要在Output unit里选尺寸单位。
其他选项默认。
点OK后放在PCB板的旁边。
（检查这个表的字母和外框形状是否有重复的。
）金属化孔和非金属化孔文件的导出步骤：选Manufacture\NC\NC Drill。
首先在NCParameters里设置：Format里前面的选3后面的选5。
（即整数位3，小数位5。
和Artwork里的设置要一样。
）Coordinates里选Absoiute。
Output units 里选英寸或毫米。
然后勾选1和3项。
（即省首零，和Artwork 里的设置要一样。
）然后Close。
回到NC Drill画面。
勾选1、2、3项。
点Drill即可。
会在PCB文件的路径下产生3个文件，后缀名为drl的2个和1个叫nc_tools_auto.txt的文件。
要交给板厂的。
Gerber导出步骤1、首先在Artwork里把所有要出底片的层定义好。
建立每个层的文件夹。
比如：TOP、BOTTOM、L2、L3、SM-TOP、SM-BOT、SS-TOP、PT-TOP、Outline、Drawing 等等。
然后，打开每个文件夹所需要的那些层。
比如：Drawing文件夹里，要打开：Board Geometry里的Outline层。
Manufacturing里的Nclegend-*-*层、Ncdrill_Legend层、Ncdrill_Figure层。
其余的层全部关闭。
然后对着Drawing 文件夹点击鼠标右键，选Match Display。

1.2 生成钻孔文件如果是普通的圆孔，则添加钻孔文件就好，添加钻孔文件操作步骤：Manufacture-->NC-->Dril Parameters或者直接点击图标-->注意选公/英制-->close-->Manufacture-->NC-->NC Dril-->Drill或者Manufacture-->NC-->NC Dril-->NC Parameters，设置同上-->Drill。
系统将自动生成一个.dri后缀文件，如果只有一种通孔，那么生成一个.dri后缀文件，如果有埋盲孔，则每一种埋盲孔都生成一个.dri后缀文件。
1.3 生成铣刀数据文件如果是非圆形孔（异形孔），那么需要添加铣刀数据文件，步骤如下：Manufacture-->NC-->NC Route一般默认参数即可，注意单位-->Route但是如果两端是半圆，中间是矩形则不算异形孔，算圆孔。
并且在CAM350里面看光绘文件的时候，Route这个层什么都没有。
Allegro中导出坐标文件的方法
Allegro 软件是Cadence 公司出品的面向中高端企业用户的PCB 设计软件，主要针对高速、高密度电路板设计，尤其在通讯等领域被广泛应用，目前最新版本号是16.0。
