Relocation and reference points
The relocation of Zoom3D is a necessary operation to allow continuing the operations with Zoom3D
inside the same site and with the same reference system. The relocation is necessary in the following
situations:
Measure – Continue
measures in a new position
After starting the measuring job, it is necessary moving the Zoom3D to
measure some invisible points by the actual position. Locate Zoom3D in
a new position and start the Relocation procedure.
Measure – New session
The measuring job hasn’t been completed in a single session and it’s
necessary to acquire new measures. Locate Zoom3D and start the
Relocate procedure.
Stakeout
It has been loaded a job sheet with points and/or a stakeout drawing.
To define the position of Zoom3D referring to the job sheet it’s
necessary to perform the Relocation procedure.
Reference points
The relocation procedure can be performed basing on reference points correctly recorded
or basing on points present on a job sheet. Reference points are specific points, unmovable
present in the site that are opportunely measured and photographed to be used simply and
quickly in relocation procedures. Reference points are visualized in sequence in the
corresponding box of the main window of the software.
Adding a reference point
1. Press the button to create a new reference point.
2. Assign a name to the point
3. Measure the reference point with precision
4. For the reference point it’s shooted also the photo allowing a rapid and sharp selection of the point
when Re-positioning.
The reference point can be inserted also in the command Measure.
Delete a reference point
1. Select the reference point from the list and Press the button .
Calculation of the current position from reference points
If you have at least two reference points it’s possible to calculate the position
and the orientation of the Zoom3D through the direct measure of the same
points. We recommend however, for a better precision of the calculation, to
use at least three reference points.
1. Select the operation Reference points
