This command allows you to draw a homerun only without drawing the loops associated with the circuit.

Circuiting and HomerunsDraw Homerun Only
Click on the device you want to draw the homerun from. This could be a light fixture, receptacle, switch, junction box, or a piece of equipment. Press space bar and Design Master will insert the homerun only from the device you chose which will reflect only the circuit that particular device is on. At this point, you may position the homerun as you wish by clicking to anchor the arrow on the drawing. To combine homeruns, see Combining Homeruns.
If panels have already been placed on the drawing, the voltage drop calculation will run each time you place a homerun. The program will display the distance between the panel and the homerun, as well as the percentage voltage drop for the homerun. This information will appear in the command line of AutoCAD, or you may press F2 to bring up the AutoCAD Text Window screen to view the voltage drop information. For more information about voltage drop calculations, see the information about the voltage drop calculation parameters.
There are many occasions when you may wish to use this function, but two are worth mentioning here. The first is when you have a busy drawing such that loops will clutter the plan rather than adding helpful information. The second is when you have drawn the loops already and manipulated them to make them perfect, but need to update the homerun. Using the Draw Homerun and Loops command would undo all your work on the loops, so you should use the Draw Homerun Only command instead.
