Zones are special areas inside a terrain by which you can gain information about bigger areas.
When creating a zone, instead of adding new points to the terrain inside the contour of the zone, zone contour is added to the terrain as discontinuity line.
Zone enables a separate region representation such as parking, gardens, etc.
In addition to this you can use zones to modify a terrain in a similar way as you do it with the plateaus.

Note: The difference between plateau and zone is that a zone fits the terrain points to the specified heights but no operation is performed on the solid.
Creating zone
There are different possibilities to define a zone; by polygon, rectangle or point inside a closed polygon, etc.
1. Select a terrain to an area of which you want to assign a material.
2. Specify the profile of the new area by using the Profile definition tool in the Ribbon bar.
3. Choose the zone material and type: Fit to terrain, Slanted surface by 3 points, Horizontal surface with elevation
Fit to terrain
On the selected area the zone fits to the height of the terrain. Only its material representation can be different from the terrain.
Slanted surface by 3 elevations
Slant zone can be created. Fits the terrain points to the plane defined by three points.
Horizontal surface elevation
On the area of the zone elevates the terrain points to the specified height.
Modify zone
A zone can be modified similarly to the plateau.
