25.8.7 Inverse width peg
The route widths and coordinates for center pegs on every calculated curve can be found by using inverse
width peg calculation.
• There are two methods for specifying arbitrary width peg coordinates: key entry and observation.
PROCEDURE Using key entry to specify arbitrary width pegs
1. In the second page of the OBS mode screen, press
[MENU], then select "Road".
2. Select "Alignment" to enter the route calculation menu.
3. Select "Road topo" to enter the road topo menu.
4. Input the arbitrary width peg coordinates.
5. Press [OK] in the screen shown in step 4 to display the
coordinates and point name of the center peg.
6. Press [OK] in the screen shown in step 5 to display the
route width and point name of the width peg.
7. The next width peg can then be set by pressing [OK].
• The center peg can be set-out by pressing [S-O].
