So my goal here is to highlight a couple rooms/spaces that already have receptacles in them. I want to do it so I can highlight several rooms, and have the receptacles in each room power to one breaker. For example, a room has 3 receptacles in it. I want to power those 3 receptacles to a breaker of a panel. So that means another room with a couple of receptacles in it should be powered to the same panel but on a different breaker. This can save me so much time. How would I go about doing this?
Creating electrical systems is only available as of Revit 2018. There are a handful of custom nodes that will help you group your fixtures by room. From there you can create a new system (per room) assigned to a panel.
