Indicating Double Home Runs Correctly in Revit MEP

Revit MEP will allow you to indicate double home runs when circuiting electrical fixtures.  This can be done by simply dragging a home run arrow from one electrical circuit to a fixture that is on a different circuit. The result will show a double arrow head on the home run and the circuit tag will call out both circuits.

Two Single Home Runs

Double Home Run

The one thing that has always bugged me about this is that Revit would also still show the home run arrow head tying the two circuits together.  Every time I taught this, I was asked how do you get rid of the arrow head tying the two circuits together?  Up until today, I did not think you could.  I have now found a way and it is very simple.

All you have to do is to duplicate the plan using the Duplicate with Detailing.

As soon as the plan is duplicated the arrow head goes away.

Double Home Run Without Extra Arrow Head

The only downside is that the duplicated plan must remain in the project.  If the plan goes away then the arrow head comes back.  Weird, but it solves the mystery of how to turn off the unwanted arrow head.


  1. So the arrow heads for each circuit cannot be an edited family (more like a built-in family type)? Have you not heard from Autodesk if this is something that can be manipulated or changed for not all MEP folks like the arrow heads from the other comments I've read online.

    - Just curious

  2. The arrow heads can not be modified. They are what they are. I have not heard of any plans of adding this feature to the program. Sorry.
