NX Motion Simulation, Collision Detection, Minimum Distance Measurement

(OP)
Hey guys, this is my first post here so please forgive me if i'm doing something wrong.

I'm currently using Motion Simulation under NX9.

I have 2 questions:
Firstly, I'm trying to simulate the motion of a pawl and ratchet.
What i've done currently is set a harmonic driver on the pawl, as well as set a torque load on the ratchet.
What i'm hoping to achieve is for the ratchet to stop when it comes in contact with the pawl, and move when the pawl opens.

I've been playing with the parameters under Insert>Connector>3D Contact but to no avail.
Basically i need some sort of collision detection.
Am i doing this right?

Secondly, I am able to measure the linear magnitude between 2 markers.
However, I am trying to measure the minimum distance between a point and a surface on the pawl (which is moving).
You can do this within the modeling environment with Measure>Minimum Distance, but I wish to plot these values automatically in motion simulation.
Is there any way to do this?

Thank you all in advance!

Regarding the second question, ive found a workaround as per the following thread:

it seems this function is not available for now.. but it will do.
still needing advice for the first question!
