Thanks Jason .
But it is possible.
When I work with roundabouts radius> 50m I can do it without problems.
The problem is when working with a roundabouts radius < 50m .
In my case 30m .
When I create a superelevation section, a bandwidth of 100 m ( -50, + 50) is generated.
I think that's because I did not draw well for a 30m radius roundabout .
Is there a variable that controls the bandwidth generate and can be modified by the user to put a value < 30m ?
Thank you very much .
