Design Data
You can use the Road Output commands on the Cross Section menu to sim-
plify the process of creating surfaces and other 3D data from finished ground
road designs.
Use the Create Road Surface command to create surface data from a road
design. You can either create a new surface from the data or add the data to
an existing surface.

8 Although profiles do not support superelevation directly,
you can convert the superelevation information to a
transition to import it into the profile.
From the Cross Sections menu, choose Templates
➤ Edit
Template to define transition points at the same location
as the superelevation points on the template. From the
Cross Sections menu, choose Ditch/Transition
