After adding loads or excavations, you can easily edit the load properties (e.g. magnitude, depth, staging information).
To edit load properties:
Select Properties from the Edit sub-menu of the Loads menu.
In the Plan View, use the mouse to select the load or excavation you would like to edit. You may only select one load or excavation.
When you have selected the load / excavation, press Enter or right-click and select Done Selection.
You will see the appropriate edit dialog (e.g. Edit Load, Edit Excavation, Embankment Designer), in which you can edit the desired properties.
Right Click Shortcut
The Edit Properties option is also available as a right-click shortcut. This is actually the most convenient way to use Edit Properties, because you do not have to go through Steps 1-3 (above), you simply right-click on a load or excavation, and select the Properties option from the popup menu (e.g. Load Properties, Excavation Properties, Embankment Properties).
NOTE: the Load Properties right-click shortcut is available in both the Plan View and 3D View.
Display Properties
The display properties of loads can be edited, by right-clicking on a load and selecting Display Properties from the popup menu, or by selecting the Display Properties button in the edit properties dialog.
