160 | Chapter 12 Viewing and Editing Roads in Profile View
When you generate a profile, you can do the following:
■ Import the left and right profiles (if you sampled left and right offsets for
the existing ground).
■ Specify the station range and datum elevation for the profile.
■ Control whether the profile is created from left to right, or from right
to left.
■ Control whether a grid is inserted with the profile.
NOTE By specifying the station range, you can import a subset of the entire
profile. When you define the finished ground profile definition, you should
work with the entire length of the profile. A subset of the entire profile should
be imported only for plotting purposes.
