To Change the Elevation of a Surface

Change the surface elevations by adding or subtracting an amount from the existing elevation of all the surface points, which raises or lowers the surface.

A positive value increases the elevation; a negative value lowers the elevation.

1. In Toolspace, on the Prospector tab, expand the surface Definition collection, right-click , and click Raise/Lower Surface.
   Note: TIN or grid volume surfaces do not support editing operations.
2. Enter a positive value to raise the surface or a negative value to lower the surface.

   The surface is adjusted to the new elevation.

   The operation is added as a Raise/Lower operation to the Edits list view in the Prospector tree.

   Note: The Description column in the Prospector list view displays the value by which the surface was raised or lowered.
