Place Trunk Measurement
Place Trunk Measurement tool lets you place a circular trunk diameter element manually. The element placement requires the following preparation steps:
•Compute distance from the ground to the trunk points.
•Assign groups to separate individual trees or tree trunks. You may use Assign groups -commands or Create Point Group tool.
The tool stores tree group id and average height from ground value of matching point as attribute data of the measurement element.

This opens the Place Tree Cell dialog
2. Select tree trunk class(es) and Method: Three points.
3. Define the trunk diameter.
4. Place three data clicks in a top view to define the trunk position.
After the second data click, a preview of the trunk element is shown.
