The Master Machine Angle [MMA] 'beats the drum' and is the reference angle for all kinematically-defined chains.
The Master-Machine-Angle has a range of 0 – 360. It represents one Machine Cycle.
MechDesigner evaluates the position [as well its velocity and acceleration] of each Part in each kinematically-defined chain to be a function of the value that is in the data box and its kinematic mathematical functions.
The position, velocity and acceleration values are 'evaluated' with kinematic equations. They are not 'interpolated' from other values. This is important.

The Red Triangle moves to the left or right as you drag your mouse.
All kinematic-defined chains move instantly to the MMA as you drag your mouse.
