Creating the Finished Ground Vertical Alignments
After you have created the existing ground profile for your alignment, you
can use other commands in the Profile menu to create the finished ground
profile elements, including the finished ground centerline, offsets, and
ditches and transitions.
In the Profile menu, there are two sections you can use for defining the finished
ground elements: one section is for creating the Finished Ground Centerline,
and the other is for creating Ditches and Transitions. These two sections have
almost all the same commands listed under each heading: they both provide
commands for drawing tangents and vertical curves and for defining the vertical
alignments and listing elevations. However, even though the commands may
have the same names, make sure to use the command under the appropriate
menu heading for the action you want to take so the database and layer
information for the vertical alignments is accurate.
Creating the Finished Ground Centerlines
After drawing the tangents and vertical curves for the finished ground
centerline, you need to define it as a vertical alignment. When you define the
finished ground centerline, the elevational data is saved to a database that you
can then use when creating the profile.
