The Platform element is used to add an area with a fixed elevation to the site. This element
      is most commonly used for building pads. 
    
      The properties that are exposed for the platform element are summarised below.

              Boundary
               The Boundary Edit button provides access to the editor where the definition points
                can be defined for the outline of the platform area. 
              Level
               This is the level that the platform area should be (subject to any offset defined
                below). 
              Mode
               This is used to specify if the element should have Cut, Fill or both. Most
                commonly Cut & Fill will be specified. 
              Offset
              The offset option is mostly used to add construction thicknesses by specifying a
                negative offset. The options are Off, Z or it allows you to offset the entire
                surface in X,Y and Z. This is useful for accommodating for a construction thickness
                or finding a balance. 
              Side Batter
               The Platform boundary is joined to the ground by side slopes. The side batter (set as a ratio of
                vertical to horizontal), dictate the angle of these slopes. You can set the side
                batter to either External or Internal and specify different side batter angles for
                side slopes that cut into the ground and for those that fill into it. Turning side
                batter off will result in the Platform being joined to the ground with vertical
                sides.  Between the Cut and Fill ratios is a double-arrow button which, when
                depressed, will synchronise Side Batters. |
