Hinge on Center / Edge : determines if the super elevation is
computed by rotating the road around the centerline or the road’s
edge.
Note: When hinging on edge, the road is actually rotated around the
end of the first segment of the template that leads into the super
elevation.
Only the first segment is adjusted with a super elevation. The length
and slope of any segments beyond the first will not be adjusted from a
super elevation.
Check… : checks the road for errors and displays the results in the
Roads Report screen, described on Page R-405.
