Is your CAM software 2d and 3d capable?

You'd prepare it for machining in an entirely different way between 2d and 3d, depending on what kind of shape you box turns out to be - sometimes a combination of methods is needed, so a picture of your design might help us to advise you.

Generally though, much more than 50% of things can be machined by using the 2d method, but 3d stuff is best employed for curvy shapes such as cars, coat-of-arms and computer mice types of shape etc.

So for 2d, you'd probably want to create a 2d outline shape from the edges of a solid and project it to the X,Y plane, from which, most CAM software would import these curves for machining as a DXF file.
