You can control the display of the coverage grid in the 2D and 3D Graphics windows and set graphics so that the progress of coverage calculations is clearly marked. In addition, you can set the display of coverage results, with contour graphics depicting the various levels of coverage provided by the assigned assets over time.
Graphics associated with the display of the grid and the progress of access computations are defined in the 2D and 3D Graphics properties for the coverage definition object. Graphics associated with the quality of coverage are defined in the 2D and 3D Graphics properties for the Figure Of Merit object.
To set parameters for the display of the coverage grid, right-click the coverage definition object in the Object Browser, and click 
to launch the Properties Browser where you will find 2D and 3D Graphics properties.
To set parameters for the display of coverage quality, right-click the Figure Of Merit object in the Object Browser, and click to launch the Properties Browser where you will find 2D and 3D Graphics properties.
