Station equations are used to adjust the alignment stationing. The most common reason for doing so is the insertion or removal of curves. Inserting or removing a curve would require re-calculating the stationing of an entire alignment. Using station equations eliminates this.

Station equations can create either a gap or overlap as shown in the following diagram.

Forward Station Equation

Select the station equation file. A dialog box appears with a list of all EQN?????.GSI files available. Move

the cursor to the file needed and press . The

"SELECT ALN FILE" display will return and the cursor will be highlighting the Log Filename. The filename can be changed or the default name can be accepted.

When all files have been selected. Continues to display "CHAINAGE & OFFSET". Prior to the "CHAINAGE

&OFFSET" display appearing, you will see a brief message about checking for errors in the selected files.
