Creating Existing Ground Profiles
You can draft an existing ground profile in your drawing, and then add finished
ground roadway design geometry to represent what the roadway will look like
in profile view.
Before you create a profile, configure the profile settings. For more information,
see Changing the Profile Settings in this chapter. When you create a profile,
an invisible block is inserted at the profile insertion point. This block holds the
information specific to that particular plot of the profile including the location
in the drawing, the vertical exaggeration, and the layer settings. This block also
holds all the Values settings for the profile, which is why the settings must be
configured before you use the Full Profile, Surface Profile, or Quick Profile
command.
Editing the Vertical Alignments with the
Vertical Alignment Editor
You can use the Vertical Alignment Editor to edit or create any existing ground
or finished ground vertical alignment. If you have already created the existing
ground surface, then you can use this editor to view or edit the information that
was generated. You can also use the editor as an alternative to the Sample From
File and Sample From Surface commands to create existing ground or as an
alternative to the Define FG Centerline and Define Ditch/Transition command
to create finished ground information.
Characteristics of the Vertical Alignment Editor

Unlike the Horizontal Alignment Editor, the Vertical Alignment Editor is not
dynamically linked to the drawing entities. From the Profiles menu, you can
choose FG Vertical Alignments
ä
Import command (or the DT Vertical
Alignments
ä
Import command) to import the changed profile alignments
into the drawing.

The station values must fall within the range of the alignment.

If a curve length does not meet the required length set for the K value, the
minimum curve length is flagged in the Vertical Curve Detail Window
section of the Vertical Alignment Editor dialog box. The minimum K values
can be adjusted from the Vertical Alignment Editor using the Values button.

The Edit Vertical Alignment command prompts for an existing ground
surface to edit if you sampled multiple existing ground surfaces. Use the
arrow keys to select the surface to edit, and then press ENTER. You can edit
only one surface at a time. You can access finished ground information no
matter which surface you select.
n
The Vertical Alignment Editor uses the precision values set by the Drawing
Setup command to display the values.

After you create the profile data with the Vertical Alignment Editor, you can
use this information to generate profiles. You can create existing ground
center, and left and right profiles with the Full Profile or Quick Profile
commands. To import the finished ground centerline into the drawing, click
