Just a tip...

Don't know what CAD software you're using so don't know if it has this, but start using layers if you haven't already!
Layers makes things much easier to move around and tweak. You can pick layers to be invisible so construction lines and anything else can be isolated and removed at a whim. Different colors for different types of parts can help you keep the drawing easily organized (besides just looking cool  ).
And using blocks can be very handy too. After making things into blocks, you will soon have a custom library of "parts" which you can then choose from and drop into place, move around, etc. It's similar to copy & paste, but easier.

Playfield looks great. Of course. I'm too tired to run laps, so I'll just have a beer.
