Let us say I want to model a truss structure. The bars are originally not connected. In the Interaction module I see the Coicident Connector Builder. The documentation states "connectors are between pairs of vertices". I can see that is true when I apply this to the structure, as only pairs of nodes are connected. That is a problem: there are three bars at some joints, and they are not connected all three into a single unit, but rather into two pairs. Hence the structure is a mechanism. Am I missing something?

Here is my sample truss:

Is this even possible? If so, how does one do that?
