If anyone can help me, I am trying to simulate how many springs fit in various containers. I am trying to mate the spring in order to be constrained or tangent to the faces of the container and to other of the same springs, but after the first mate It doesnt allow me to mate in anymore. How can i apply more than one mate in the spring in order for it to no go thru the box or other springs. I am trying to find out how many fit in various containers. If someone can tell me the best way or aproach I can take, i would really apreciate it, Thanx in advance.
