Pin the Link

It is much too easy to accidentally select a linked model in Revit MEP and accidentally move it, so the link should be "pinned" in place so that people don't move it on accident.
To accomplish this select the link file and from the Modify RVT Links ribbon click the pin button.
Once the element is pinned a blue "pin" control will appear on the link. If the link is accidentally moved you'll see an error message indicating that it can't be moved.
