Cutting out an oval sign

[Ghscncclass]

Hello. What do I need to do in order to cut out my sign similar to the two example attachments? I want the white cut out and all of the black to stay, but i am not sure how to do this. Thanks.

In your cad turn off fill on your shapes so you just have the outlines. It will make it easier to see what you are doing. Now look at the overlaps. SheetCam will cut along the lines so your overlaps won't work. Trim your outlines so you just have the path that the cutter should follow. You will also need to add another oval for the outside of the sign.
Once you have cleaned up the drawing you should be able to load it into SheetCam and do an outside offset to cut the sign out.
