Selecting Objects

Most actions that are performed on an individual object require you to select the object first. When an object is selected, it is referred to as active.

Selected components are drawn in the selected color, which is blue by default, and the selected status overrides any other color code that may be applied to the object. Let’s say, for instance, that MOTOR-0001 is out of service so that by default it appears gray. If you select it, the select status overrides the out of service status, and all of the objects

associated with MOTOR-0001 turn blue. If you deselect it, the One-Line Diagram remembers that it is out of service and it turns gray again.

Many actions can apply to several objects simultaneously. You can select individual and groups of objects using different techniques, and you should experiment with all of them to find the technique that works best for you.

3.7.1. Selecting Individual Objects

Click on objects to select them individually. To select a single object

1. Point to the object you want to select. The mouse pointer becomes the select pointer .

2. Click the object.

If you have already selected some objects, you can also add or remove single objects from/to the selected set. The selected set can contain as many objects as you want. To add or remove a single object to a selected group

1. Press the SHIFT key.

2. Point to the object you want to add or remove. The mouse pointer becomes the select pointer.

3. Click the mouse button. The select status of the object will change. 4. Release the SHIFT key.

3.7.2. Selecting a Group of Objects

To select multiple objects, draw a selection box around them. This saves a great deal of time when you want to select objects that are located in the same area of the One-Line Diagram — that is if they are grouped spatially.

To select a group of objects

1. Point to one corner of the selection area. 2. Press the mouse button.

3. Drag the mouse pointer to the opposite corner of the selection area. As you drag the mouse pointer, you will see the selection box being drawn.

4. Release the mouse button. All of the objects that are surrounded by the selection box are selected.

Note: The selection box must completely surround the object you want to select. Partially surrounded objects are not selected.

If you have already selected some objects, you can add or remove a group of objects. The selected group can contain as many objects as you want.

To add or remove a group of objects to a selected set 1. Press the SHIFT key.

2. Point to one corner of the selection box. 3. Press the mouse button.

4. Drag the mouse pointer to the opposite corner of the selection box, which should contain all of the objects you want to add or remove to the group. As you drag the mouse pointer, you will see the selection box being drawn.

5. Release the mouse button. This changes the select status of all objects that are surrounded by the selection box.

3.7.3. Selecting All Objects

To select all of the objects on the One-Line Diagram simultaneously, click the Edit>Select All command.

3.7.4. Running a Query to Select Objects

Running a query is a very effective method of selecting components that are grouped by function (rather than by location). Using a query you can select components that share

Draw a selection box around the objects that you want to select.

any attribute or group of attributes. For example, you can select all motors over 500 hp, or all three-winding transformers. Note that queries select symbols only (with the symbol names and datablocks), not connections.

Running a query on a One-Line Diagram de-selects any previous select, searches the active One-Line Diagram for components that meet the criteria of the query, and selects those components.

This section briefly summarizes the process of running a query on the One-Line Diagram, but is not intended as an in-depth discussion of queries, which are extremely powerful and flexible tools. For a more complete discussion of queries, refer to the “Queries” chapter. To run a query

1. Do one of the Following:

• Click the Run>Query command.

• From the Toolbar, click the Query button .

2. Under Query Category, select the category from which you want to select your query. 3. Under Query Result Set, do one of the following:

• If you want to replace the results of the last query with the results of the new query, select the Replace option button.

• If you want to combine the result of the query with the results of a previous query or queries, select the Merge option button.

4. Do one of the following:

• In the list box, select the query you want to run, and choose the Run button. • In the list box, double-click the query you want to run.

After you run the query, all of the devices on the One-Line Diagram that satisfy the conditions of the query appear in blue, indicating that they are selected.

Select the query you want to run.

Choose the Run button to run the selected query.

Replace previous query results, or merge several query results.

Tip: Use the Find Unconnected Components query to quickly locate any components that you accidentally left unconnected.
