specifies how far from the connection point out on the template you want to
draw the vertical match line for the subgrade. This match line matches
upwards into the template, using a vertical line, rather than matching out at
a grade towards a ditch.
The following prompt is displayed:
Subgrade break match grade percent <5>:
NOTE
This value is only used if superelevation is applied to the template and the
Fixed Break subgrade superelevation option is used. Press ENTER to skip
this prompt if you are not using superelevations.
The subgrade break match grade percent is the grade for the bottom of the
subgrade, from the outer edge of the superelevation region (plus or minus the
modifier) to the side slope.
9 Type a subgrade break match grade percent, and then press ENTER.
The following prompt is displayed:
Subgrade break point offset modifier <0>:
NOTE
This value is only used if superelevation is applied to the template and the
Fixed Break subgrade superelevation option is used. Press ENTER to skip
this prompt if you are not using superelevations.
10 Type a Subgrade break point offset modifier and press ENTER.
With the Fixed Break subgrade superelevation option that is available in the
Superelevation Parameters command, the subgrade below the template
superelevation region superelevates, and the subgrade outside of the
superelevation region wont. The subgrade break point offset modifier option is
used to set the location of this break point in relation to the outer
superelevation point. If the default of 0.00 is used, then the break point occurs
directly below the outer superelevation point. If a positive value is entered, then
the break point is shifted by that amount toward the centerline and a negative
value shifts it away from centerline.
The material table is displayed, if it exists in the folder set by Set Template Path

more than one subgrade material is desired, or press ENTER to end the
command.
