How're you going to color the parts? Since all the parts are chrome...
On a different topic, do you actually cad the chains when you cad the robot? I didn't try to do that but I'm always curious how. I didn't recall any teams from World's that used PTC had actual chains on their models...
The only models that I had saw with chains on it for VEX / FTC are the ones that were cad by cody (smartkid)...
Oh and how do you make the gear on the motor mounted on the motor shaft mesh with the other gears?
