OK… I’ve tried this several different ways and cannot make it work. I have a floating pier that is attached to fixed piers via 2 bridges. The floating part needs to move up and down with the tide with the bridges following, I’m thinking this is similar to a suspension system with multiple parts moving in concert. I just cannot get this thing to connect without getting over-defined.
At first I created axis at each of the connection points to mate together, then I tried mating with points, but each time when I try to add the last mate it goes over-defined. Is there a method to this madness? In my head I can see how it might be over-defined but for the life of me I cannot think of a way to put this together so that it is not. Additionally, I need to add 3 more mooring booms which will act in a similar way, so that there will be a total of 5 parts connecting the fixed and floating parts. How do you automotive guys (& gals) get a wheel to travel up and down while connected to several parts at the same time?
