Drive Grid (DriGri)
Type: Interactive Application
Drives to grid points within a user-defined polygon and allows reading of those points as symbols, spot elevations, or text elevations. DTM may be run during the read process and the elevation from the DTM surface may be driven to when moving to new grid points.

Parameter Notes
Grid Offsets
Defines X,Y distances to add when driving the instruments to the grid points.
Z Control
Defines location of Z motion. NOTE: Not available on all instruments.
Drive Z to DTM surface if active
If this parameter is set to "Yes", the elevation from the DTM surface will be used when driving to a grid point. It is possible to run DTM at any time and strengthen the surface based on previously read grid points. DTM may be run without exiting Drive Grid.
Example Scale Factors

Comment
|
1.0
|
No scale factor
|
-1.0
|
Reverse direction of Z motion
|
-2.5
|
Reverse direction and multiply speed by 2.5
|
.5
|
Divide Z motion speed by 2
|
Update Graphics (UpdGra=)
Specifies whether graphics should be updated when a point is read. Turning this flag off avoids pausing on slower computers when reading points in stereo roaming. Home may be pressed to manually update graphics.
