How to measure the distance and angle of rotation

[Me09]

Hello guys, I have two complex solid body which have a relative rotational motion, I want to track the distance between any two points of bodies and measure the angle of rotation, any idea?

Thanks eli215,
The general queries can give instant information from the view point but if I want to track and record the data in the output what should I do?

Can we do a sensor?
