<– Return to How to Use One-Line Diagrams
The one-line diagram that is created the first time you run one of the Generate commands is typically not what your final version will look like. The initial layout might need to be modified to be more clear. Changes will be made that must be reflected in the diagram. This article explains how to make these changes after the initial creation of your one-line digram.
The Update Command
The one-line diagram is not automatically updated when you make changes to your model. Instead, you must manually update the one-line diagram after you have made changes by running the Update command.
The following changes take place during an update:
- All labels will be updated with the correct values.
- Layers will be updated.
- Any distribution equipment that has been removed from the project will be removed from the one-line diagram.
- Any connections between distribution equipment that have changed will be updated.
Inserting New Distribution Equipment
There are two ways you can add distribution equipment to your one-line diagram after it is initially generated:
Insert Distribution Equipment Manually: You can use the Insert Distribution Equipment command to manually insert a piece of distribution equipment on the drawing. Once you specify a location on the drawing, feeders will be inserted to any upstream or downstream equipment.
Generate Again: You can use the Generate One-Line or Generate Riser command again. Any distribution equipment that is missing from the drawing will be inserted automatically along with any corresponding feeders. Distribution equipment and feeders that are already inserted will not be modified.
Moving Distribution Equipment
There are two ways you can move distribution equipment that is inserted on your drawing:
Use the Standard CAD Move Command: You can use the standard CAD MOVE command. This method works well when you have a small number of entities to move.
Select the distribution equipment and move it to a new location.
If you do not select the feeder, it will stay in the same location except for the part connected to the distribution equipment you moved. The connected end will move with the distribution equipment.
If you do select the feeder, it will stay in the same shape but move with the distribution equipment. The end not connected to the distribution equipment will stay where it is to maintain the connection to the other piece of equipment.
Use the Design Master Move Command: You can use the Move Distribution Equipment command to move everything connected to a piece of distribution equipment. This method works well when you need to move a large group of connected equipment.
You will be prompted to select a piece of distribution equipment. That equipment, along with all of the downstream feeders and connected distribution equipment, will be selected.
Move the distribution equipment as you would with the standard CAD MOVE command. All of the selected items will be moved together.
For information on moving feeders, visit One-Line Diagrams: Feeders.
Modifying Distribution Equipment Values
To make changes to the underlying model of a piece of distribution equipment, use the Edit Distribution Equipment command. Select the piece of distribution equipment to modify and the corresponding dialog box will appear. You can also make changes using the commands in the Distribution Equipment section of the DM Electrical menu.
Changing the Blocks Used
To change the graphics that are used in the one-line diagram, use the Change Graphics command.
If you select a piece of distribution equipment, you can change the graphic that is used for the equipment.
If you select a feeder, you can change the graphics used for the different blocks that are inserted on the feeder. You can select multiple feeders and change all of their graphics at the same time using this command.
To change the layers used in the one-line diagram, use the Change Layer System command.
Select a piece of distribution equipment or a feeder, then select the layer system that should be used.
