I recently participated in a Siemens conference in Las Vegas, where I met some representatives from Siemens Germany. They had a stand with NX Mechatronics Concept Designer, and they had a great demo showing some of its capabilites. I was impressed by the freedom and intuitiveness you have in testing out mechanisms within this application, so I decided to make a tutorial on simulating a Roller Chain mechanism:
Hope you find it useful.
