The Edit Pressure option (Perimeter Support) allows you to edit Pressure which has been added to the perimeter of the excavation. With this option:

• You can change the magnitude of the Pressure or the method of force application.
• You can change the start and end points of the Pressure.

1. First, make sure you are viewing the Perimeter Support Designer view (select the Perimeter Support Designer button from the toolbar).
2. Select the Edit Pressure option from the Edit sub-menu of the Support menu.

TIP: You can also right-click directly on a Pressure you wish to edit and select Edit Pressure from the popup menu. This will directly display the Edit Pressure On Perimeter dialog, so you can skip step 3.

   • Hover the mouse over either endpoint, and the cursor will change to a 4-way arrow symbol .
   • When you see this, you can click and drag the endpoint to a new location on the perimeter.
   • As you move the endpoint, the Pressure will be interactively updated on the screen.
   • when the endpoints are moved to the desired locations, right-click and select Done , or press ENTER, and the updated Pressure will be applied to the model.
