Q: How is the layer chosen for the circuit loops that are drawn between devices?
A: There are a number of settings that control the layer that is chosen for circuit loops.
The “Default circuit layer system” Option
The Default circuit layer system option controls the layer system that is used for the circuit. To see the value of this option and change it, use the DM Electrical->Customization->Options->Edit Project List command. It is in the Circuits, Load Types, and Wire Sizes section.
The original setting in the customization is Same as One-Line Device. When this setting is selected, the layer system of the circuits will be the same as the layer system of the one-line device that are part of.
You can change it to be a specific layer system. If you do, all the circuits in the project will use the selected layer system.
The One-Line Device “Layer System” Setting
If the Default circuit layer system option is set to Same as One-Line Device, the layer system of the one-line device the circuit is connected to is used. To see the value of this setting and change it, go to DM Electrical->One-Line Devices. Select the command that corresponds to the one-line device type the circuit is part of. In the dialog box there is a Layer System setting. The value of this setting is used for the layer system of the loops.
The Circuit “Layer System” Setting
The layer system for each individual circuit can be modified to be different from the value set by the Default circuit layer system option. To see the value of this setting and change it, go to DM Electrical->Circuiting and Homeruns->Circuiting. Select the circuit. The Layer System setting is on the right side. It will be set to Default to start. You can manually change it to any layer system defined in the project.
The Device the Loop is Connected To
Each type of device can have a different layer used for the loops. To see and change the layers, go to DM Electrical->Customization->Layers->Edit Project List. Select the Layer System in the top-left grid. In the top-right gird, scroll to the CIRCUITS section. Locate the layer key that corresponds to the type of device the loop is drawn from.
For example, a loop drawn from a receptacle would use the CIRCUITS-RECEPTACLES layer key. The original layer associated with this layer key is EN-POWER-CIRC for the New layer system and EE-POWER-CIRC for the Existing layer system.
Whether the Loop is a Homerun or Not
Loops and homeruns use different layer keys. The CIRCUITS layer key is used for the loops between devices. The CIRCUITS-DEVICE TYPE-HOMERUN layer key is used for homerun loops.
