This dialog allows you to assign a demand and demand pattern to the currently selected element or elements. The dialog appears after you have used the Add Demands command in the Demand Control Center or the Unit Demand Control Center and then selected one or more elements in the drawing pane. The dialog itself will vary depending on whether it was accessed from the Demand Control Center or the Unit Demand Control Center.

From the Demand Control Center

Enter a demand value in the Demand field, then choose a previously created pattern in the Pattern list, create a new pattern by clicking the ellipsis button to open the Patterns dialog, or leave the default value of Fixed if the demand does not vary over time.

From the Unit Demand Control Center

Enter the number of individual unit demands in the Unit Demands <Count> field. Choose a previously defined unit load from the Unit Load list, or create a new one in the Unit Demands dialog by clicking the ellipsis button. Choose a previously created pattern in the Pattern list, create a new pattern by clicking the ellipsis button to open the Patterns dialog, or leave the default value of Fixed if the demand does not vary over time.
