Field Perimeter Drawings

Our team is planning to build a field perimeter. I have looked but can not find a set of drawings for just the perimeter. I think I remember a set a few years ago but can not find anything but the Powerup specific drawings. Can anyone help send me in a useful direction? I could use a set of CAD drawings to figure what we need. Thanks

The game & season manual page on FIRST’s website has that information:

AndyMark has drawings for a wooden field perimeter here.

Thank you. The Solidworks files really helped after I figured out which of the Assembly files was the complete field. The name was a bit cryptic.
