If you post your dxf or f3d, a number of us would be willing to CAM it for you and explain what we did. @DonP and @TinWhisperer will sometimes do a video so you can see how they pick things. Others will show screenshots and descriptions at key places to help you see what/why/where fors.

That is the thing: this is an adventure. Embrace it.
