Job Settings (System)
This tab allows you to define the units for the current job.
 Distance
: Select the units that you want to use. Choices include US Feet, International Feet, and Metric. If US Feet
or International Feet is selected, you have the option to display distances as decimal feet (Dec Ft) or Feet and
Inches (Inches). This is a display property only and will not change the format of the data recorded to the raw file.
 Angle
: This offers the option of degrees (360 circle, 60 minutes to a degree and 60 seconds to a minute) or gons
(also refered to as grads- 400 circle and fully decimal). An angle of 397.9809 gons is equivalent to 358 degrees, 10
minutes and 58 seconds. (Note: you can verify this in Cogo, Calculator, Conversion tab). The Angle Unit
configuration impacts commands such as Inverse, Traverse, Sideshot, Input-Edit Centerline and other commands
where a direction is displayed or entered.
 Zero Azimuth Setting
: Allows you to specify the direction for zero azimuth, North or South.
 Edit Projection List
