Step-by-step:

Once you have imported a surface model, you can change the way it appears in the Plan View by adjusting the Display Settings.

  1. In the Tree View, right-click the surface and select Display Settings.
    The Tree View with the Surface menu displayed, and Display Settings selected.

 

  1. In the Display Settings dialog box, Surface tab, in the table, turn the available layers on and off so that the surface displays as desired. For example, turn the Surface Color Fill OFF.
  2. Turn ON the Data.
    The Display Settings dialog box with settings configured so that Surface Color Fill is off, and Data is on.

 

Notice that the Data view displays the survey points, in this case, as orange circles.

The Plan View with survey points displayed

  1. In the Display Settings dialog box, turn ON the Triangles

The surface forms a mesh based on those points. Anywhere within the boundary of this surface, the program can calculate a level based on linear interpolation.

  1. Zoom in to see the points.

Points that are very close together are more accurate.

The Plan View, zoomed in to show areas of accuracy

  1. Zoom out and pan the view to see the edge.

Where the triangles are larger, the surface is much less accurate because the points are so far apart.

The Plan View with areas of the surface called out to indicate less accuracy

  1. In the Display Settings dialog box, turn OFF the Data
  2. Turn OFF the Triangles—with no layers active, there is nothing to display.
  3. Turn the Surface Color Fill layer back ON.
  4. Expand the Ramp drop-down.
  5. Choose the color scheme you prefer for the thematic map that controls the view.

Notice that the key in the top-left corner of the Plan View changes to reflect the new scheme. The more colors that the theme contains, the more varied the colors will be on the surface, and the more detailed the key.

  1. In the Display Settings dialog box, select the rainbow theme again.
  2. Make note of the level values it is indicating.
  3. Click and drag the color arrows to change the points at which the colors change in the key.
  4. To restrict the key values to a minimum or maximum, turn ON the Restrict to Minimum and Restrict to Maximum Or, edit the values in the type boxes.
  5. To control the opacity of the surface, click and drag the control bar at the bottom to be either more Opaque or more Transparent.
  6. When you are finished editing the Display Settings, click Close. Your changes are automatically in effect.
