When creating a new model in aspire.

When creating the tool path

Aspire creates these holes prior to cutting the squares out. This takes half the cut time. I thought that this might be to prevent some tear out but when the 'final' cut of each square is made it cuts outside of this hole. What is the reason I have them?

For anyone who cares
If you don't want to make square holes

you need this outer vector. I makes sense of course but its not something I thought of when I had holes instead of raised areas.
Even if the model shows raised squares.

I do realize that the 3d model is disregarded for the VCarve. That is to say I don't need it at all. I started this idea as a 3D one so I included it to be a little more thorough.
