Feature Lines have always carried the X,Y (like an Alignment) and the Z (similar to a Profile). I'm glad to finally see this AWESOME update in Civil 3D 2017, giving users the ability to create a Corridor from a Feature Line.
The only change with Corridors, in the new Civil 3D 2017 version, are the new names for the Corridor properties of Alignment and Profile columns. They are now referred to as Horizontal Baseline and Vertical Baseline. Everything else works similar to how Corridors have worked in the past.
It's a fun new way of creating corridors to tackle road, rail, stream or utility designs.
