Main Assembly

The main assembly is for viewing the entire robot. It's important we constrain to our origin planes so we can use them to measure our robots and constrain game objects to our robots.

Placing the Chassis in our Main Assembly

In our main assembly file (mine is called ! Bingus), place your ! Chassis.iam.

Use a flush constraint between the flange of the cross brace and the XY Plane, with an offset of 2.5/2.

Use a flush constraint between the edge of the cross brace and the YZ Plane, with an offset of 15/2.

The XZ Plane will become our ground plane. This is an important plane, because it is how we will measure our robot for sizing, or constrain game objects to the "floor".

Use a mate constraint between the bottom of the drive channel and the XZ Plane, with an offset of (4.125/2)-0.5. 4" wheels are actually 4.125". We divide that by two, and subtract half because the center of the wheel is 0.5" up from the bottom flange of the drive.
