Sampling the Existing Ground Profile Data from
the Processed Cross Sections
If you have already generated existing ground cross sections, then you can
obtain existing ground data for profiles from the cross sections.
NOTE
You can use this command in tandem with the Sample From File command
on the Cross Sections menu to create profile data. For instance, if you have
an ASCII text file with all of your section information, and then sampled
this information to create existing ground section information, you can use
the Sample From Sections command on the Profiles menu to create profile
data based on this section information.
To sample profile data from existing ground section information
1 From the Profiles menu, choose Existing Ground
ä
Sample From Sections.
If you} Then}
sampled existing ground data for
cross sections from only one surface
the Sample From Sections command
retrieves the information for the profile
from that surface.
sampled existing ground data for
cross sections from more than one
surface
the Select Section Surface dialog box
is displayed.
Select the surface to sample (for profiles),
and then click OK.
NOTE
If an existing ground profile definition already exists for the current
alignment, it is overwritten. A dialog box displays, asking you if you want
to keep the finished surfaces. Click Yes to keep the finished ground vertical
alignment information, or No to delete the finished ground information.
Creating the Existing Ground Profile Data by
Using the Vertical Alignment Editor
An alternate method of creating existing ground data for profiles is to use the
Vertical Alignment Editor. You can use this editor to enter profile data for the
existing ground centerline, and left and right offsets. You can also use this
dialog box to edit data that you sampled from a surface or a text file.
