I think it would be cool if after you built and exploded a corridor you could run a command that looked at the separated linework’s name and moved it to a predefined Layer.
Example you explode the corridor and have say 68 lines on layer FG Model(Finish). Run the command and it takes all of you EP_RT and EP_LT and moves them to Layer FG-EP.
Benifits depending on what you what out of your design. You get 3D linestring instread of the corridor creating a Surface. The 3D lines you can once you get intersection done you can trim lines and adjust elevations to match. Then also you can use those 3D lines to export for the field crews to use for layout/offsets. Once you create and finish the design. you will have to explode the sideslope/template. after it gets exploded those newly created lines will be highlighted “ DONOT UNSELECT THOSE LINES” while they are highlighted relayer those lines, as they will be undependant from the Side Slope.
