Curb Return Fillet

This assembly is used to model the curb return regions at intersections. All curb return alignments should run in the same direction (clockwise) so this one assembly will be used for all 4 quadrants.

This assembly consists of 1 LnExtendBase subassembly, and 1 CGBasic subassembly. For information on the parameters of the individual subassemblies, consult the respective help file.

LnExtendBase – This subassembly is used to model the lane portion of the curb return quadrant of an intersection. The Inside base extension width parameter is used to model the subgrade and base layers beneath the curb and gutter. All crown point codes are removed. The crown feature lines are developed with another baseline along the side road centerline.

CGBasic - This subassembly is used to model the curb and gutter portion of the curb return quadrant of an intersection.
