if you are clearing out space with a 1/16 bit… do yourself a favor and just run the whole design with the V-bit. It will probably save you a bunch of time and bits.
Then copy the outline to a separate workpiece . click the outline and copy it ( alt+C), open the work piece at the bottom of the page and click add. then just paste it (alt+V). It will place it in the same spot as the previous workspace. then cut it out with an 1/8" bit or larger.
