2. Select the first reference point from the list
3. Measure the reference point with precision
4. Select the second reference point from the list
5. Measure the reference point with precision
6. It’s possible to proceed the procedure and measure further reference points. The more the
measured points, the more is the calculation precision.

Calculation of the current position from points of the job sheet
If you have no reference points, it’s possible to calculate the position and
the orientation of Zoom3D through the measure of at least two points
present in the job sheet; the points to measure have to be measured with
precision in the site. So you can relate the position of Zoom3D in the site
with data present in the job sheet.
This situation is typical when you import data on a job sheet and you must perform a stakeout of these
points; in this case it’s possible to measure at least two points present both in the job sheet and both in
the site to proceed then with stakeout procedure. We recommend in this case also for a better precision
of the calculation, to use at least three reference points.
1. Select the operation Points of the job sheet
2. Select first reference point from graphic window
3. Measure the reference point with precision
4. Select the second reference point from graphic window
5. Measure the reference point with precision
6. It’s possible to proceed the procedure and measure further reference points. The more the
measured points, the more is the calculation precision.
7. A window visualizes the precisions obtained both about distances and both about the heights.
Reference axis
Position and orientation of Zoom3D are determined by measuring two points
stating the direction of X axis (abscissa). First point measured will assume
coordinates (0,0,0) instead the second point measured will assume
coordinates (distance from first point, 0, 0).
The position of Zoom3D and the position of all next measured points will be
calculated basing on this reference system.
1. Measure the point Origin of the reference system
2. Measure the point defining the Direction of the reference system
