Shifting Station Numbers
Use Shift to shift a range of station numbers by a specified number of feet (or meters) or in the direction of an existing facility. Use the option labeled Distance when shifting station numbers by feet or meters. To shift a range of station numbers in the direction of an existing facility, use the option labeled Shift To Facility.
Using Shift allows you to add or subtract a fixed distance to station numbers for a range of readings in a survey. This function is typically used when station numbers are not known when performing the survey and they need to be shifted to correct station numbers.
