ElectroBIM Feature
ElectroBIM is an add-in for Revit that will create a one-line or riser diagram for you based upon your electrical system.
Link graphics on your one-line riser diagram to existing panels and transformers in the model. Create new panels on the diagram, insert them in the model, and connect them using a single command.
Diagram labels use shared parameters that update automatically as you make revisions. Make changes in either the drafting view or the model.

Diagram labels use shared parameters that update automatically as you make revisions in either the drafting view or the model.
