The Trace Architect's Receptacles command is used to trace a receptacle layout from another drawing that does not have Design Master entities.
Before using this command, create receptacles using the Receptacle Project Schedule command.
This command should be run on the drawing from which you are copying the receptacle layout. Do not run this command on the drawing you are using for your electrical design.
To trace a receptacle layout, go to
Ribbon: DM Electrical->Devices-> 
Trace Architect's Receptacles
Pulldown Menu: DM Electrical->Receptacles->Trace Architect's Receptacles
Background Mapper Dialog Box
See the Trace Architect's Light Fixtures section for more information about how this command works. The Background Mapper dialog box works the same way in both commands.
