Corridor not snapping to crown and edge of pavement (ETW)

My corridor targets a centerline alignment, ETW alignments, and the existing surface, but the crown and ETW are not snapping onto the surface. What am I doing wrong?sc53122.pngsc353122.pngsc253122.png

It looks like your edge of pavement elevation overrides are actually targeting a centerline profile. Check and set them to the correct edge of pavement alignment and profiles and see if that helps.

If your baseline is the centerline alignment usually your crown should follow the profile specified under the vertical baseline on the corridor.  If it is the surface profile, then the crown should snap the existing surface. Otherwise, it will follow the profile specified in the corridor.

As shown by Owensharp, your EOP has elevation targets. So the EOP snap to the elevation profile specified in the slope and elevation targets.

you may check your targets and also increase the corridor frequencies.

Do I need multiple profiles for the same surface? Right now I have offset alignments for ETW and one profile along the CL

You need an existing profile for each offset alignment so you can use them in the elevation overrides
