Creating and Editing Profiles
From the Profile menu, the Create Profile submenu has commands that create
full, surface, quick, and grid profiles. Once you have created a profile, you can
make the profile current; list existing ground elevations for the profile
centerline; move or export the profile to recreate a profile information block;
change profile properties; and remove the profile definition block from a
drawing.
Creating Profiles
After you create the existing ground data for an alignment, you can generate a
profile. You can create a full profile, which includes a datum line, datum
elevation, existing ground, existing ground text, and grid base. Or, you can
create a quick profile, which is created without a horizontal or vertical grid base
or station elevations. To define the finished ground definition, or to annotate
the profile create a full profile.
If you sampled multiple surfaces, then you can create subsurface profiles.
Typically you would create a full profile of the existing ground top surface, and
then create subsurface profiles for any other subsurfaces you sampled.
When you generate a profile, you have the option to import the left and right
profiles (if you sampled left and right offsets for the existing ground). You can
also specify the station range and datum elevation for the profile, you can
control whether the profile is created from left to right or right to left, and you
can control whether a grid is inserted with the profile.
NOTE
By specifying the station range you can import a subset of the entire
profile, but for defining the finished ground profile definition you should
work with the entire length of the profile. The ability to import a subset of
the entire profile is just for plotting purposes.
