No need to recreate the sections. Make the corridor and add it to the sample lines via "sample more sources. Is the proposed corridor the only component? are the section based on a different alignment?
I could be wrong but maybe the back of sw can be the attachemnt to the assmbly dode similar to a curb sub

Ok
Then you will want to use an assembly and an offset assembly. your road cl profile will carry the assembly and the alignment an pgl you created for the sidewalk will carry the offset.
you can look into the UrbanRepalceSideWalk sub that uses the outside edge. (I'm ignorant on the use of marked points but if you understand them great.)
Maybe the regular USW can be used in reverse; for example if the sidewalk is on the right, attach it to the right offset on the left side and set the cross slope to a negative value

I don’t like the marked point either. I got the USW to work in reverse but the marked point is off from the c/l of road alignment and not the back of sidewalk. Do I need to create a sidewalk alignment using miscellaneous alignment? And will that follow the c/l of road alignment? The proposed sidewalk meanders along the existing roadway.
The existing sections and the profiles are in their separate drawings. What drawing should I create the corridor? My guess would be the profile.
These are the steps I used to design the sidewalks and I like to link them unto the sections already created.
- Draft sidewalk unto plan views
- Layout back of sidewalk profile grade onto profile that shows centerline of road alignment
- Converted the back of sidewalk profile grade line (polylines with PVI’s) to layout profile in the same profile view
- Create sections showing only existing conditions
Maybe I’m missing something else here. I’ve attached my drawings to illustrate what I’m trying to do. Thank you for your help!
Thank you,

I suggest using an offset assembly for the side walk this will allow you to build the corridor along the CL and show in you cross sections from CL. To use the offset assembly you will need an separate alignment and profile for the back of walk. Note: the front of side walk will follow the behavior assigned to the assembly i.e cross slope.
You can create the corridor anywhere you have a data shortcut. the profile drawing is suitable.
- Draft sidewalk unto plan views (ok)
- Layout back of sidewalk profile grade onto profile that shows center line of road alignment (this can work but see offset explanation above)
- Converted the back of sidewalk profile grade line (polylines with PVI’s) to layout profile in the same profile view (not sure what this is doing for you)
- Create sections showing only existing conditions (ok, but presumably the goal is to get the SW onto the section, use Offset assembly)
FYI: the offset assembly works in conjunction with an assembly that would be assigned to CL. in other words the corridor is built on CL using EG profile, the offset targets BOSW alignment and profile. Note using the offset build the sidewalk perpendicular to the offset alignment, which may be desirable if it meanders from CL.
Question: how are you planning on dealing with the front of sw? It may be in cut or fill? I guess you may have accounted for that in the BOSW PGL. You could add a daylight link to the front, I guess.
