Input items 5 through 11 are strictly optional design files. It should be pointed out that items 8 and 9 (Template
Point Profile and Template Point Centerline) enable template IDs to follow any defined centerline or profile and
provide total flexibility of design. Lane widening, matching existing curb lines, special ditches, etc. can be easily
accomplished with these two options. The template IDs simply ''string along'' or follow these pre-defined alignments,
and the rules of the template apply to all other template ID points.
The Output Files section allows you to specify files to store the processing results. The Section File creates a
final grade section file that can be drawn with Draw Section File. The Topsoil Section File creates the modified
existing ground section file if Topsoil Removal is set in the input. This ''post-topsoil removal'' section file can
be used for earthworks calculations to compare any stage of work, using Calculate Sections Volume under the
Section pulldown menu. The Coordinate File creates a coordinate file containing every break point in the final
grade. The point descriptions include the station, offset and template ID. Whether to include the subgrade points
as well as the final surface points is determined by the Include SubGrade Points in Output CRD File option on
the next dialog. To the right of the Output Files is the option to create new output files or append to existing
output files. If you extend the road, or revise a portion of the project, you can simply ''Append'' rather than
overwrite. The first time that you run this command for stations 0-1000, you would set Output Files to New. Then
you could run this command again, possibly with new inputs, for stations 1000-2000 and set Output Files to Append.
On the next dialog, there is a Save Settings button to store all the settings from the first and second dialogs
into a specified Road Design File with an (.RDF) file extension. Recorded (.RDF) files can be recalled later using
the Load Settings option.
1> Centerline
Specify the name of the Centerline file with this option. The (.CL) file contains the horizontal alignment geometry
for a project. This parameter file must be specified if you want to have earthworks centroid corrections computed,
generate final coordinates, Disturbed Area Polyline, and/or use Triangulate & Contour. The centerline file can be
