Behavior
This subassembly provides a rail platform that ties between two different rail alignments for a variable width, and a profile for a variable slope. Place the platform subassembly insertion point on the centerline alignment and profile of the primary rail and adjust the behavior by setting the input parameters and the Secondary Rail target parameters listed above. Additional target parameters are provided to control the platform offset and elevation, overriding the platform input parameters.
Layout Mode Operation
In layout mode, this subassembly draws the dual rail platform.
Point, Link, and Shape Codes
