Stretch Site

The Stretch Site command adjusts the size of all, or selected data in a job file. The most common use is to correct data entered at the wrong scale. If part of all of a grading plan was digitized at the wrong scale, the Stretch Site command allows you to change the scale of the data. Below are the steps used to stretch the data.
