Set Looping Options
|Up Previous Next|
The Set Looping Options command is used to set options used when drawing circuit loops and homeruns.
To change the options used when drawing loops and homeruns, go to
Ribbon: DM Electrical->Circuiting and Homeruns-> Set Looping Options
Pulldown Menu: DM Electrical->Circuiting and Homeruns->Set Looping Options
Looping Options Dialog Box
Draw Loops Between Circuited Devices: Controls whether loops are drawn between devices on the circuit and how circuit callouts are displayed. This setting controls a number of related options, detailed in the table below. If the cell is green, the feature for that column is enabled. If the cell is red, the feature for that column is disabled. For example, option 2 enables drawing loops between devices and disables all circuit callouts, while option 7 enables all features.
Loops are not required to calculate voltage drop and wire lengths in takeoffs, but the lengths will be estimated. If you want more accurate calculations but don't want loops on the final printed drawing, turn loops and circuit callouts on and insert them on a non-plotting layer.
Share Neutrals on Combined Homeruns: Whether neutrals are shared on combined homeruns. This must be set to No if you are using the 2008 NEC.
To share neutrals in accordance with the 2008 NEC, a common trip for the circuits on the combined homerun is required.
One way to create a common trip for the circuits is to create three single-pole circuits and join them using the Change # of Poles button on the Circuiting dialog box. See the Change # of Poles section for more information.
The other way to create a common trip for the circuits is to create a three-pole circuit and connect single-pole devices to the circuit using the Circuit to Phase button on the Circuiting dialog box. See the Circuit to Phase section for more information.
Select Preferred Circuiting Direction: Whether the preferred circuiting angle prompt is used when drawing homeruns and loops.
The preferred circuiting angle is used to guide how loops are drawn between devices. When possible, loops are drawn parallel to the circuiting direction specified.
Select Loop Center Point: Whether the arc center point prompt is used when drawing homeruns and loops.
The center point is used to help automatically draft the loops in an organized manner. All of the loops that are inserted will arc away from the center point.
Loop to Same Circuit First on Combined Homeruns (Light Fixtures): For combined homeruns, whether loops are drawn to the closest light fixture on the same circuit or the closest light fixture on any circuit.
Loop to Same Circuit First on Combined Homeruns (Other Devices): For combined homeruns, whether loops are drawn to the closest device on the same circuit or the closest device on any circuit.
