Angles

On the Survey tab, in the Calculations group: Select Manual | Angles to calculate the included angle between each pair in a list of horizontal angle pairs. This function also displays the mean and the range of the included angles. In addition, you can enter a list of vertical angles and the program will normalise them all to Face Left and display the mean and range.

To use the Angles function:

1. Choose the angle units.
2. Choose the zero vertical. Zenith means that 90 or 270 is horizontal; <90 or >270 is an elevation and >90 or <270 is a depression. Horizontal means that 0 is horizontal, positive values are elevations and negative values are depressions.
3. (Optional) Enter a Report file name. 
4. Enter pairs of horizontal angles and/or a list of vertical angles and run the function.
