3 Type SR to activate the Surface Control options to redefine the template
superelevation regions.
The SRfcon option displays the following prompt:
Connect/Datum/Redraw/Super/Topsurf/TRansition/eXit <eXit>:
4 Type S for the Super option to define the template superelevation regions.
The following prompts are displayed in turn:
Outer left superelevation point:
Inner superelevation reference point:
Outer rollover point:
Outer right superelevation point:
Inner superelevation reference point:
Outer rollover point:
5 Select the points to define the left and right superelevation regions.
Define the left superelevation region first, followed by the right superelevation
region. When defining the region, pick the outer edge of the region, and then
the inner edge using AutoCAD object snaps. All surface segments between these
region points superelevate.
The grade between the two points is used as the base grade for the normal
crown condition when calculating superelevation.
After picking the two region points, select the outer edge of the rollover region
if required. If the template does not have a shoulder that requires a rollover
region, then click Enter at the rollover prompt for None.
6 Press ENTER to exit the command when you are finished picking the points.
