Specifying an Irregular Canopy

Since trees are not always perfectly symmetrical, the Existing Tree tool allows an irregular canopy shape to be defined by setting the measurements, in four different directions, from the center of the trunk to the edge of the canopy.

If the trunk had previously been repositioned by moving its control point, it is reset to the default position when an irregular canopy is selected. The trunk cannot be offset for irregular canopy shapes.

To specify an irregular canopy shape:

1. From the Object Info palette of a selected existing tree, select Irregular Canopy Size.

The Irregular Canopy Size dialog box opens. Specify the canopy size in four directions.

►    Click to show/hide the parameters.

Parameter	Description
Use Canopy Offsets from Center of Trunk	Select to specify an irregular canopy shape
North/East/South/West	For each direction, specify the distance from the center of the trunk to the edge of the canopy

2. Click OK. The 2D and 3D appearance of the tree displays with an irregular canopy shape, roughly based on the selected symbol definition.

The irregular shape can be oriented differently by entering a North Angle offset from the Object Info palette.
