Pie Panel Etching

I bought a engraver today, Thinking I could etch the panels into the dome.
WRONG!!!
I had to take the Dremel and carefully etch the lines without cutting through the dome.
Free handing these lines is a real pain and then using a file to smooth and fine tune the edges is even worse.
The lines will not be perfect and in this picture it's hard to see the line edges,
Because they are clear.
I know it looks really cut crappy, But it's not. The plastic just makes it look this way.
