All of the board I have developed over the last several years have been
simple rectangular or round boards defined by the Dimension Layer (20). I
have a new client that wants several boards developed that ALL include
milled slots, and other odd shapes, both as cutouts in the outer edges, and
as cutouts in the interior of the boards. I have several questions
regarding the development of these boards:
1) Do I use Polygons in the Milling Layer (45) for all of my
non-outside-dimension CNC operations?
2) If so, what "width" do I use?
3) How do I develop a CAM file for Layer 45 that a PC board house can use?
Thanks for your assistance.
