Edit History
Whenever you rebuild a surface, you must reapply the edits that you made
to it. To save time, all edits that you make to a surface are saved in the Edit
History folder in the Terrain Model Explorer.
The Edit History folder stores all the edits that you make to a surface so you
can automatically repeat them when you rebuild the surface later.
You can open the Edit History folder to view the edits you have made to a
surface, as shown in the following illustration.
When you select the Apply Edit History check box as you rebuild the surface,
all previous edits are repeated in the order that you made them. You can also
change the edit history list. To not repeat a step in the edit history, delete the
item from the list.
Creating Contours
Contours portray the elevational values of a surface at specified intervals, as
shown in the following illustration.
