Defining Subassemblies
289
You can select two different types of shoulder subassembly for each side of the
template: one for cut situations and the other for fill situations. The program
determines whether to use cut or fill shoulders based on the position of the
connection point that the shoulder is to be attached to. If the connection-point-
out of the curb (or the template if you do not specify a curb subassembly) is
above the existing ground, then a fill shoulder is applied. If the point is below
ground, then a cut shoulder is applied.
The connection-point-out of the shoulder subassembly connects to the ditch
foreslope if you are using ditches, or to the design slope if you are not using
ditches. If you do not use subassemblies, then the slope attaches to the
connection-point-out of the template.
NOTE
Templates must have subassemblies as well as surfaces. If subassemblies are
not required, then you must use the Nulls subassembly name in place of
having a subassembly. In addition, if you want to use a shoulder
subassembly but not a curb subassembly, then use the Nulls subassembly
for the curb subassembly.
To select subassemblies to attach to templates
1 In the Subassembly Attachments dialog box, under Left, select the
subassemblies you want to attach to the left side of the template. You can type
subassembly names into the boxes, or you can click the Select buttons to
display the Subassembly Librarian dialog box, from which you can select the
subassembly to use. The Subassembly Librarian dialog box provides a graphical
display of the subassemblies that are located in the template path.
When you specify the Left subassemblies in Subassembly Librarian dialog box,
their names are copied automatically to the Right section of the dialog box.
2 Under Right, you can select different subassemblies to attach to the right side of
the template. The subassemblies you specify for the left and right sides of the
template can be the same or different.
3 Click OK when you have finished selecting the subassemblies.
Using the Subassembly Librarian Dialog Box
You can use the Subassembly Librarian dialog box to select a subassembly to
attach to a template. All of the subassemblies that are located in the template
path are listed in the Selection list of this dialog box.
NOTE
By default, a Nulls subassembly is included in this list. Templates must have
subassemblies as well as surfaces. If subassemblies are not required, then
you must use the
Nulls
subassembly name in place of having a
subassembly.
To select a subassembly from the Subassembly Librarian Dialog Box
1 Click on the name of the subassembly you want to attach to the template.
A graphical representation of the subassembly is displayed in the preview
window, and the subassemblys name is listed in the Name box at the bottom of
the dialog box.
2 Click OK to select the subassembly.
