Station Equation File
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.
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.
