In this video tutorial you can find one answered question:
I would like to solve in Creo Mechanism. As You can see in the picture that I attached, there is one body (object 1) which is supported on three feets. Another body (object 2) moves in one direction (along x-axis) on guides that are mounted on object 1. My problem is to set proper connection between feets and object 1 and object 2, which would allowe me to measure force reaction change in each feet, while movement of object 2. Is it possible to do such simulation in creo?
