Difference

Calculation of coordinate differences between two points. When two points have been clicked you get :

The program always compares the two last shown points. A line will be drawn to show the calculated distance.

dX, dY, dZ, dA, dB

Differences in coordinates.

dXY, dXYZ, dAZ, dBZ

Horizontal and slope distance between the two points.

Direction, Vertical, Slope

Direction, vertical angle and slope between the two points. dZ defines the sign of slope. Direction is diplayed in cross section and profile windows, if points have XY-coordinates.

Constant point 1

If you click the checkbox Constant point 1, the point P1 will remain constant, and all points shown after that will be compared to that constant point.

Automatic saving

If the checkbox is selected, all calculated distances are written to the result file.

Slope

Slope output format:

This settings affects only screen display. Result file receives always base slope value.

Save

The last calculated distance will be written in result file. The saved distance will remain in screen until the function is closed all results are cleared. When you exit the function, the sum of all calculated distances will be written in result file. If both points are on the same line, line number is also written.

Control

Saves difference values as control attributes to original points. Control arrows are then drawn according the control measurement settings.

Reset

Removes all lines from screen and result file. With the Shift-key removes the last calculated distances from screen and result file.
