Allows two points forming a straight line to be observed and a point to be set out at a certain distance from the line. In order to do so the initial Point 1 and the final Point 2, as well as the distance to origin of a point over the straight line, Distance to origin, and the normal distance to this line, Distance to Line, of the point to be set out are requested.

 

Both these distances can be negative or positive. In the case of the former, a negative distance indicates that the point is before point 1, or the initial point. In the latter case, it indicates if the point to be set out is to the left (negative) or to the right (positive) of the straight line.

 

 

Once all the data requested is entered, the following screen is displayed once ok button is clicked.

 

 

The information displayed includes:

 

Name of the numerical information mode in brackets. (North)

 

Existing distance between the current position and the point to be set out. D 3.04

 

Measured height. MH 561.63

 

Distance to be moved to the right or left. Rgt 1.39 . Done is indicated when this distance is less than the transversal tolerance indicated in the configuration.

 

Distance to be moved forwards or backwards. Bwd 2.71. Done is indicated when this distance is less than the longitudinal tolerance indicated in the configuration.

 

Distance to rise (R) or fall (L) to achieve the theoretical elevation. R 0.03 (in this example the points have an elevation of 0.0).  H OK is indicated when the elevation difference is less than the vertical tolerance indicated in the configuration.
