    • Coordinates: A: (5.00,-15.00) and B: (5.00, 15.00).
      
13. Click Add.

    The LL2 load appears in the drawing area.

    
14. In the Cases Selection box of the Selection toolbar, expand the Cases drop-down menu and select 4: LL3.
    
15. Go to the Load Definition dialog, and then in the Surface tab, click (Uniform Planar Load on Contour).

16. Enter - 0.10 in the PZ: box.
17. Click Contour definition.

    The Contour definition area expands.

18. To create the contour for the load, enter the following point coordinates:

    • (-10.00, 0.00), click Add,
    • (-10.00, 5.00), click Add,
    • (-20.00, 5.00), click Add.

    Tip: You can use the Loads table to modify the defined loads. For example, you can change the loads types, the list of elements where loads are applied and the values of these loads. You can also use this table to add new loads to the structure.
23. Click the icon in the upper right corner of the table to close the Loads table.
    
24. Click in the drawing area to deselect the panel.
25. Save the project as Plate_Applied_Loads.rtd.
