Assign Template Point Profile
This command assigns profile (.PRO) files to template point ID's
like EP (edge of pavement), SH (shoulder) or DL (ditch line),
storing this information in a template point profile (.TPP) file
which can be used by the Process Road Design and
Road Network
commands. The purpose of the profile assignments is to allow
separate profiles for template points that are independent of the
centerline profile. For example, a ditch grade could have a
different profile than the centerline. Multiple template point
profiles can be assigned so the amount of control is unlimited. The
Template Point Description corresponds to the name set in the
Design Template command.
If you want the template ID point to follow a special slope or
vertical alignment, use Assign Template Point Profile. The
combination of using template point centerlines and profiles
applied to particular template ID points is a design method
sometimes referred to as "strings", where template elements string
along special horizontal and vertical alignments. The rules of the
template in terms of distances and slopes to the next point in the
template will resume after the template point centerline and
profiles are applied.
Prompts
First you are prompted to create a new Template Point Profile
(.TPP), or edit an existing one.
Next the Define Template Alignments dialog is presented, showing a
list of existing Template ID-Profile assignments. To add a new
assignment, first pick the Set button to set the Reference Template
file (.TPL), then pick the Add button. This brings up the Template
Point Profile Settings dialog. First, pick a Template Point
Description from the List, which is derived from the components
defined in the Template. Next, pick the Specify Profile File
button, to choose the file (.PRO) to assign to the Template Point
ID. Alternatively, instead of picking a profile, you can use the
Screen Pick button to select a 3D polyline from the drawing which
the program will use to generate a profile. Next, enter the Station
range to Apply the assignment, select the Station Reference,
specify if this assignment is for the Left, Right, or both sides of
the main centerline, and finally specify the method to apply the
assignment. Since the template ID profile can change the
relative position of the template ID from the centerline, you have
two options for how to fit in the template ID profile: Hold Offset
or Hold Slope. Hold Offset will keep the same offset for the
template ID and adjust the slope to the template ID. The Hold Slope
will keep the same slope to the template ID and adjust the offset
to reach the template ID profile elevation. Use Hold Offset when
Template Point Profile is used in conjunction with Template Point
Centerline, where a single template ID is defined to follow both a
special and distinct horizontal alignment (centerline) and vertical
alignment (profile).
Pick OK. Back in the Define Template Alignments dialog, pick
Add to add another assignment, Edit to edit an existing assignment,
Report to create a report of the template point profile data,
Delete to delete a defined assignment, or Save to Exit.
Now Process the road design employing the newly defined Template
Point Profile assignment. In the Process Road Design main dialog,
pick the Template Point Profile button to select the new file
(.TPP). You could also create a new Template Point Profile file
directly from this dialog box by picking the Edit button and
specifying a new file name.
