n
Existing Ground  Resample: You can resample the existing ground
sections (from a surface or a file) after applying templates to the cross
sections. If you do this, then you are prompted to overwrite the existing
section information. If you respond yes, then the existing ground section
information is deleted first, then re-sampled. If you respond no, then the
new existing ground information is merged with the previous surface
information.
Re-sampling the existing ground always maintains the finished ground
section information. If you used the Existing Ground
ä
Edit Sections
command to interpolate subsurfaces, then you must re-interpolate the
subsurfaces.
n
Existing Ground  Add Sections: You can create additional cross sections
after you have applied templates, either by re-sampling the sections or by
manually entering the information with the Existing Ground
ä
Edit Sections
command. A new cross section acquires all of its design control from the
section that is immediately before it, except for the template elevation which
it extracts from the centerline finished ground profile.
If you have attached any horizontal or vertical alignments to the template,
such as transitions, ditches and ROW lines, then you must re-attach them
for the new sections by using the Edit Design Control command. You only
need to reprocess superelevation if you modify the superelevation
parameters with the Superelevation Parameters command. If you do change
the superelevation parameters, then you are prompted when exiting the
command to reprocess the superelevation information.
n
Template  Edit: You can make edits to a template, such as adding
transitions or superelevation points, after you have applied the template to
the cross sections. The Edit Template command automatically reprocesses
the cross sections when you exit the command. After you have reprocessed
the cross sections, you can use the View/Edit Sections command to see if the
modified template has been applied as expected.
n
Slopes  Depth, Step, and Surface: If you modify a slope table that you have
already applied to a template, then use the Process Sections command to
update the slopes.
n
Edit Design Control: You can use the Edit Design Control command at any
time to modify the design control for a range of stations (sections). When
you modify and re-process a range of stations with this command, only the
specific criteria that you modify will be reapplied to the selected range.
For example, if you only modify the ditch width using the Edit Design
Control command, then the new width will be applied to the selected range
of stations, but nothing else. This is because ranges can overlap and you may
have modified individual sections with the View/Edit Sections command.
