You can access this tool from the following:
The Corridor Objects dialog is a summary of all corridor modeling objects and provides an excellent method of managing data. Clicking on the various categories located on the left side of the dialog displays the appropriate data in the center section. Clicking on a single line in any display places the information to the layout at the right side of the dialog, where much of the information may be edited.
Graphical edit will operate only if a start or end station is selected.
