Links are the connections between slots on objects which pass information during a simulation run. They propagate a value from a slot on one object to a slot on a different object. Several links may exist between different slots on two objects, but only one line is represented on the workspace. By hovering over the link, all the linked slots are displayed in a tool tip.

There are three utilities for viewing, creating and deleting links: Context Menus, Smart Linker, and Edit Links dialog. See Editing Links in Building a Model for details.
