An individual tree will not have elevation or vertex location gizmos. The loca-
tion is controlled by the path that defines the row or the perimeter that defines the
stand area. The elevation is always set to match the terrain, but you can use the
Translate Z setting in the Properties panel to move a tree up or down in the z-axis.
editing a row or stand
If you click a tree that is part of a row or stand, you will notice that a line appears
representing the pathway (row) or perimeter (stand). This line will present vertex
location grips when in edit mode, and you can use these grips to control the path
of a row or the perimeter of a stand.
More options are available if you double-click one of the trees in a row or
stand. This will select all of the trees and provide you with gizmos that control
all of the trees at once. These include move, rotate, and height gizmos. The
height gizmo will set the height of all the trees at once. Just remember that
InfraWorks randomly adjusts the tree heights so that they are not all the same
in order to make the trees appear more natural.
An additional user interface component that you have not seen yet is the
Feature Density slider (see Figure 4.8). When you double-click a tree that is
part of a row or stand, the slider appears and can be used to control the spacing
of the trees. InfraWorks also incorporates random spacing into this feature to
make the row or stand appear more realistic.
