3 Do one of the following:
n
Press ENTER if the surfaces are symmetrical and you drew only the left side
of the template.
n
Type N for No if the surfaces are asymmetrical and you drew the entire
template.
NOTE
Symmetrical surfaces are not physically mirrored at the centerline during
the Define Template command. The template must be imported in to the
drawing using the Import Template or Edit Template command to see the
right-hand side.
4 Select all of the objects that make up the template by picking them from the
drawing.
You can either select each surface individually or use a window or crossing
window to select the template surfaces. Each surface must be made up of a 2D
polyline created with either the AutoCAD PLINE command or the Draw
Template command.
When you are finished selecting objects, press ENTER at the Select objects
prompt.
The command highlights the first surface you selected and displays the
following command line prompt:
Surface Type (Normal/Subgrade) <Normal>:
5 Press ENTER to select Normal.
A material table is displayed, if it exists in the folder set by Set Template Path
command. If the material table does not exist, then you are prompted to enter
the Material Name (maximum 20 characters) at the command prompt.
6 Select the surface material, and then click OK.
After you select the surface, the command finds the next template surface you
selected (if you selected more than one) and highlights it. Repeat steps 5 and 6
until you have specified a surface material for all of your surfaces.
7 After you select the surface materials, the following prompt is displayed:
Pick connection point out:
Connection points are used to attach the subassemblies, such as a curb or a
shoulder, to the template. If no subassemblies are attached, then the connection
point out is used as the point from which the ditch slopes or design slopes
extend.
If the template is symmetrical, then you define the connection point on the
one side of the template and the definition is mirrored to the other side. If the
template surface is asymmetrical, then you need to define connection points for
each side of the template.
NOTE
Use object snaps to select the connection point accurately.
After you pick the connection point out from the drawing, the following
prompt is displayed:
