Creating a Slikcreen for parts on the bottom in Eagle

Hi all, I have an SMD board with some parts on the bottom. I use the CAM function to create files for board production. I get a file for the top silkscreen, but none for the bottom. How do I get the bottom silkscreen file. Thanks in advance Ed.

:smiley: I figured it out! Open CAM Gerb274x. Note there is two silkscreen layers Default is both set to top. Select one and change layers to include Dimension, Bplace, Bname and change extension from .plc to .pls. Then process job :lol: Ed.
