It's called "relief cutting"
Since you can only cut the area of a closed object you have to create
objects outside the lines of your design.

The easiest way is to pull a square behind/outside the design and use
your software to do a trim, or in Corel you can do a "Combine" and it
cookie cutters the background so you end up with new objects that are
cuttable. The concept is that it uses the shape of your original
object and "punches" it out of the larger background object you just
added. I don't know what drawing software you use. In a pure CAD
system someone else will have to tell you how to make cutout objects
from the overlap of two objects. From there you just select the new
objects that are not the raised part and do an inside pocket (remove
all the material). Some advanced packages and sign routing software
will let you do an area clear of the background without creating the
new objects. Areas inside your design that need to be recessed can be
selected and cut to depth.
