Labeling the Vertical Curves
To create labels for vertical curves, use the Label ä Vertical Curves command.
These labels show the Beginning of the Vertical Curve (BVC); the End of
Vertical Curve (EVC); the length of the vertical curve; the PVI elevation; the
Algebraic Difference; the K value; and the high/low point (a tick mark is placed
at this point).
When you use this command, the tangents from which the vertical curve was
created are broken at the BVC and EVC. Circles are inserted at the BVC and EVC
points with a radius of 0.5 units when you plot the drawing. The labels go on
the finished ground text layer as specified in the profile settings.
NOTE
The vertical curve label command uses the label increment and precision
that you set with the Values command. However, once the Values
settings are set and the profile is created, you cannot use the Values
command to change them. Instead, use the Set Properties command to
edit these settings.
To label the vertical curves
1 Set the label text size.
2 From the Profiles menu, choose Label ä Vertical Curves.
3 Select the tangents that represent the grades coming into and out of the PVI.
The command uses the PVI station and elevation determined by the tangents.
4 Select the vertical curve.
From the selection of the vertical curve, the command determines the station
and elevation of the BVC and EVC points and places the labels in the drawing.
5 Select another curve to label, or press ENTER to end the command.
The finished ground elevations are inserted along the grid base at the specified
increment assigned in the Values command.
