Click Smooth Surface.

In the Smooth Surface dialog box, specify the following parameters:
■
Select Method: Natural Neighbor Interpolation
■
Output Locations: Grid Based
The Grid Based output location interpolates surface points on a grid
defined within specified polygon areas selected in the drawing. After
the areas are defined, you can specify the grid X and Y spacing and
orientation properties.
5
For the Select Output Region parameter, click the Value column. Click
.
6
On the command line, enter
Surface
for the output region. This option
will smooth the whole surface, rather than just the area within a specified
rectangle or polygon.
7
In the Smooth Surface dialog box, specify the following parameters:
■
Grid X-Spacing: 10
■
Grid Y-Spacing: 10
8
In the drawing window, notice where some of the contour lines are
especially angular. Click OK to smooth the surface.
The display of the surface is smoothed; contours are less angular. A
Smooth Surface item is added to the Edits list view on the Prospector tab.
NOTE
The Description column in the list view displays the type of surface
smoothing that was used (Natural Neighbor Smoothing). You can delete the
Smooth Surface edit from the list, but this does not reverse the smoothing
operation until you rebuild the surface. You can also reverse the smoothing
operation by using the
U
(undo) command.
