Adding a Subsurface to a Profile
You can add an existing ground subsurface to a profile after it has been created
in the drawing by using the Surface Profile command. This command adds the
subsurface to an existing profile without adding vertical grid lines or station
elevations.
To add an existing ground subsurface to a profile
1 Using the commands from the Profile Settings menu, configure the profile
settings, if you haven't done so already.
2 Enable the use of multiple surfaces, select the surfaces to sample, and sample
the multiple surfaces, if you haven't done so already.
3 Set the current surface. This is the surface for which you generate a quick or full
profile in the next step.
4 Generate a quick or full profile for the specified alignment.
5 From the Profiles menu, choose Create Profile ä Surface Profile to display the
Profile Surfaces dialog box.
6 Select the subsurface that you want to plot over the existing profile.
7 Click OK.
The subsurface profile is overlayed on the existing profile.
NOTE
The vertical exaggeration of the profile is determined by the horizontal and
vertical scale factors of the drawing. After you create the profile, all
commands use the vertical exaggeration that the profile was created with,
regardless of whether you change the current vertical exaggeration.
For examples of vertical exaggeration, see Creating a Complete Profile in this
chapter.
The following illustration is an example of a subsurface profile:
