Create One-Line Diagram Block from this Drawing

The Create One-Line Diagram Block from This Drawing command is used to configure your current drawing to work as a custom block on your one-line diagram.

This command will not create a slide for the block. You can manually create a slide for the block using the Create Slide command.

To configure the current drawing as a one-line diagram block, go to
Ribbon: DME: Customization→Block Creation→Create One-Line Diagram Block from This Drawing
Pulldown Menu: DM Electrical→Customization→Block Creation→Create One-Line Diagram Block from This Drawing

A Design Master Electrical dialog box will appear, asking if the block will be used as a feeder or meter block.

  •   The block will be a feeder or meter block. Feeder blocks can be inserted at the ends or in the middle of feeders. The block can also be used to represent distribution equipment or equipment connections on the one-line diagram.

  •   The block will not be a feeder or meter block. The block can only be used to represent distribution equipment or equipment connections on the one-line diagram. It cannot be used on a feeder.

Creating a Feeder Block​

You will be prompted to specify the location of the upstream connection point. This is the point that the feeder from the upstream device will connect to by default.

Specify upstream connection point:

You will then be prompted to specify the location of the downstream connection point. This is the point that the feeder to the downstream device will connect to by default.

Specify downstream connection point:

You will then be prompted to specify the mirroring point. This point is displayed as a grip when the block is inserted. It is used to mirror the block over the feeder line.

Specify mirroring point:

Creating a Non-Feeder Block​

A Design Master Electrical dialog box will appear, asking whether the block has an upstream connection point. If you press the button, you will be prompted to specify the location of the upstream connection point. This is the point that the feeder from the upstream device will connect to by default.

Specify upstream connection point:

You will then be asked if the block has a second upstream connection point. If you press the button, you will be prompted to specify its location. The second point is used for the second upstream connection on transfer switches and UPSs.

If an upstream connection point is not inserted but is required on the one-line diagram, the feeder will connect to the insertion point of the block.

A Design Master Electrical dialog box will appear, asking whether the block has a downstream connection point. If you press the button, you will be prompted to specify the location of the downstream connection point. This is the point that the feeder to the downstream device will connect to by default.

Specify downstream connection point:

If a downstream connection point is not inserted but is required on the one-line diagram, the feeder will connect to the insertion point of the block.
