Correcting Civil 3D Corridor Feature Lines by Swapping Point Codes

Quite often, the baselines defined in roadway corridors represent the centerline of the road.  In fact, the default point coding on Civil 3D’s lane subassembly follows this trend.  When modeling larger roadway designs however, additional baselines may be required at locations such as curb returns, medians or lane edges.  Fortunately, Civil 3D’s lane subassembly provides multiple point code options to ensure common feature lines (Crown, ETW, Lane) are drawn at the correct locations no matter which baseline is being followed. 

In today's installment, we’ll explore a workflow that adjusts these point codes to control the type and location of feature lines created within a corridor model.  If you are interested, I've recorded a video below that walks through everything...
