Making curved roads with profile and ability to get its elevation


Hi , 

I am currently working on a project which contains curved roads/paths sloped on two sides for drainage purposes but also their level changes along with the project. In the end, the road will contain some layering and profiles (ex. stone paving finish, compacted soil under, drainage channels on side etc. )  and I have to define spot elevations on a plan to share with the constructor. 


I have read/watch many different road making tutorials but surprisingly could not find what I have searched. 


- I can make roads by using a roof tool with composite layering and be able to control slope and easily give associated spot elevations but its not an easy process to redo when there is a change in the road shape or it is not possible to define a roof angled multiple ways (for ex. a road with the 2 percent drainage slope on both sides but also going down on a slope.)


- I can model the path with a mesh tool so I can achieve more flexible modelling and be able to give spot elevations but in this case, i had to calculate grading amount manually and can not use complex profiles for layering for section views. 


-With the beam or railing tool I can assign a road profile and draw along a line, which can be edited easily but shame that I could not get spot elevations from it.  Also with the morph tool can not get spot elevations. 


The tool I am searching for is to be able to extrude my road section a path, that i can modify its elevation and in the end getting spot elevations on plan view. 


I am using Archicad 25. 


Any ideas or suggestions? Many thanks in advance.
