One-Line Diagrams: Labels

Tuesday, December 15th, 2015

<– Return to main How to Use One-Line Diagrams article.

Labels are used to insert information about your equipment and feeders on your one-line diagram. As the design changes, the information on the label will change, too.

Inserting, Changing, and Removing Labels

Use the DM Electrical->One-Line Diagram->Insert and Modify Labels or DM Electrical RT->Labels->Insert and Modify Labels command to insert, change, and remove labels on the one-line diagram. Select the piece of equipment or feeder to modify the labels of. The specific labels available will depend upon what you select to add labels to.

To insert a label, check the box on the left side of the dialog. Use the Prefix and Suffix fields to add text before or after the value defined in your model. The Value field will show you the text that will be inserted on the drawing. Use the Alignment field to change the justification of the text. Use the Scale field to change the size.

After you close the dialog you will be prompted for the location of any labels you added. There are options available at the command line during the insertion. You can use Next to go to the next label if you want to insert them in a different order than they are originally prompted. You can use Group to select another label and have the new label placed directly below it. Once you have inserted one label, you can use Insert or press ENTER to have it grouped with the last label you inserted.

To change a label, make any changes necessary in the dialog box. The labels on the drawing will be updated when you close the dialog box.

To remove a label, uncheck the box on the left. The label will be removed when you close the dialog box.

Default Label Settings

You will often make the same changes to the Prefix, Suffix, Alignment, and Scale fields in each project for a particular label. You can use the customization commands to save these changes so that the fields are filled in with the correct values by default.

Use the commands in the DM Electrical->Customization->One-Line Diagram Default Labels section and DM Electrical RT->Customization->Default Labels section to set these values.

Use the Edit Project List and Edit Standards List commands to view or edit the values. Each field will be listed for each type of equipment.  Set the fields to the default values you want to use.

The Edit Project List command will affect the current project only. Any changes made using this command will not affect any other projects. Also, the changes only affect labels that have not already been inserted on the drawing. If the label is already inserted, the current values will be used. They will not be changed to match the new default values.

The Edit Standards List command will be used when you start a new project. Any changes made using this command will not affect any already started projects.

Use the Copy Project List to Standards and Copy Standards List to Project commands to move changes between your project and standards files. Typically, you make your changes in a specific project. Once you are satisfied with your settings, you copy from that project to your standards list. If you have other projects that you are working on, you can then copy to them from the standards. All new projects will use the new standards values so you do not need to worry about them.

Grouping Labels

Use groups to arrange multiple labels in a column on the drawing. Each label in a group will be placed directly below the label above it. Moving the group will move all the labels together.

You can group labels with each other when you first insert them on the drawing. After the labels are inserted, there are three commands for working with the group.

Use the DM Electrical->One-Line Diagram->Group Labels or DM Electrical RT->Labels->Group Labels command to group labels that are already inserted on the drawing. Select the label the is in the correct location first, then select the label to position below the other label.

Use the DM Electrical->One-Line Diagram->Remove Label from Group or DM Electrical RT->Labels->Remove Label from Group command to remove a label from a group and insert it by itself on the drawing. You first select the group, then select the specific label to remove. The label will be removed from the group and the other labels adjusted accordingly. You will be prompted for a new location for the label that is removed.

Use the DM Electrical->One-Line Diagram->Reorder Labels in Group or DM Electrical RT->Labels->Reorder Labels in Group command to change the order that labels are displayed in a group.

When you use the Insert and Modify Labelscommand, the Alignment and Scale values will be the same for all labels that are in a group together. If you change it for one of the labels, it will be changed for all the other labels in the group.

Moving, Rotating, and Resizing Labels

Once the labels are on the drawing, you can use grips or our commands to modify their location.

To use grips, select the entity on the drawing. Grips will be displayed on the corners of each labels and in the middle.

The corner grips work exactly like MTEXT grips. One corner will the anchor point. When you move it, the whole label will move. The other corners control the width of the label. The label will wrap if you reduce the width.

The Alignment field for the label is set to Center there will also be a grip at the top center of the label that will act as the anchor.

The grip in the middle of the label will adjust the rotation angle of the label.

You can also use the DM Electrical->One-Line Diagram->Move Label,  or DM Electrical RT->Labels->Move Label command to move a label. Select the label to move, then specify the new location for the label. There is no difference between moving the label with the grips versus using this command.

You can also use the DM Electrical->One-Line Diagram->Rotate Label,  or DM Electrical RT->Labels->Rotate Label command to rotate a label. Select the label to move, then specify the new rotation angle. Using the command you can specify the angle by selecting a point or directly inputting a value. The command works better than grips if you want to enter a specific value for the rotation angle.

Adding Leaders

Leaders can be inserted from the labels as part of the entity.

Use the DM Electrical->One-Line Diagram->Insert Leader,  or DM Electrical RT->Labels->Insert Leader command to insert a leader. Select the label to add the leader to, then specify the ending location for the leader.

Use the DM Electrical->One-Line Diagram->Remove Leader,  or DM Electrical RT->Labels->Remove Leader command to remove a leader. Select the leader to remove.

Once a leader is inserted, you can move its location by selecting the entity and using grips.

Reusing Label Layout

Once you have spent time arranging the labels on your one-line diagram, you will want to reuse that layout in other locations. There are two different ways to reuse your label layout.

Use the DM Electrical->One-Line Diagram->Match Label and Graphics,  or DM Electrical RT->Change->Match Label and Graphics command to make the labels on one item match the labels on another. First select the item with the correct labels, then select the items to copy the labels to. The location of the labels and the Prefix, Suffix, Alignment, and Scale values will all be changed to match the original item. The specific values of the labels will be based upon your model. If you need to change the actual specification of the item, make those changes directly to the item itself.

When this command is used on distribution equipment or branch circuit equipment, the panel box size or block that is used will also be matched in addition to the labels.

When this command is used on feeders, the label locations will be match as closely as possible based upon the current routing of the feeder. If the feeders generally run parallel to each other, the match command works well. It can get confused if the feeders routes are not related. The command also matches the location of the blocks on the feeder in addition to the labels.
