Change of crossfall

Hey Guys,

 

I wanted to change the crossfall of a section of the existing road by overlaying on it and then tie it to the existing road.

I did left EOS alignment, Cl alignment and design profiles for them in which i raised the left EOS by 20 mm to the section required for design profile.

when I put the targets for the assembly (Multipurpose lane) it does not ties back to the existing levels. 

If you can let me know the the right way of doing it i ll appreciate it.

Because you raised the target profiles.. this is a logic problem for you

Thank you so much for your response.

This is what i did maybe i am not doing it right but if possible could you please guide me in right direction.

I created the surface. Did alignment for both sides of EOS's and cl. Did profiles for all the alignments. just smooth them out nothing raised this time.

Did assembly for my corridor using Multi purpose lane one sided only (left). 

Clicked on left EOS alignment to create corridor. selected design profile for that alignment and EG for daylight target.

In corridor creation parameters tab selected my right width targets to CL and design profile of CL

Now how would I be able to create that transition from existing -2.5% slope to 1% slope that leads to  onesised crossfall for a section of road.

If you could please help me i would greatly appreciate that.

It might be easier to understand what you did if you share the drawing that you are using and some screenshots.  Verbal descriptions of issues are very difficult to follow for some people.
