He then created a lower height relief around the oval which would effectively cut the shape out in a fashion. Our bit was only 2.5″ long so it wouldn’t cut all the way through but it would give us a guideline and a head start.
The outside of the oval would have another layer added. This would be undercut so we could place a ring of LED lights there to create a glow on the domed background behind the tree. This would be routed upside down. We first created a relief that was 2″ thick.
This relief was then modified by using the subtract command.
Lastly we created a 2″ filler layer. This was done as a simple offset cut file. We cut this in sections which would allow for the welded structural steel frame to be put inside the outer layers.
