嗨，孙兰， 1）您要将PCB层打印到纸张或胶片上吗？ 为此，请使用“文档”>“导出”或“文档”>“打印”菜单 2）还是在订购PCB之前检查它们？ 要检查您的Gerber文件，请单击PCB编辑器顶部工具栏中的“Fabrication output ...”。 2.1）从以下版本安装FOSS gerbv的副本： https://sourceforge.net/projects/gerbv/files/gerbv/ 2.2）下载然后解压缩您的Gerber文件 ![enter image description here][1] 2.3）然后在gerbv中，打开要检查的图层（文件>打开图层）。 ![enter image description here][2] 也可以看看： https://easyeda.com/forum/topic/How_to_negate_a_layer_for_hand_PCB_etching-sIsmEWdvN Hi Sunlan, 1) Do you want to print your PCB layers to paper or to film? To do this, use the Document > Export or Document > Print menu 2) Or is this to check them before you order your PCBs? To check your Gerber files, click on `Fabrication output...` in the PCB Editor top toolbar. 2.1) Install a copy of the FOSS gerbv from: https://sourceforge.net/projects/gerbv/files/gerbv/ 2.2) download and then unzip your Gerber file 2.3) then in gerbv, open the layers (File > Open Layer(s)) you want to check.
