superelevation of a mixed straight and curves path

Hello all,

I need to built a superlevation by an alignment with its profile done. The alignment is a mix of straights and curves, I already learned how to add a straight table editor, but when I give a look to the panorama table, I read end of crown and begin of crown as what I can edit are transitions.

Let's figure I have to do this:

0-100mt 2% left (straight)

100-200 from 2% left to 2% right (still straight)

200-300 2% right (curve)

300-400 3% right (curve)

I never want a crown section, it's a sort of drain always changing the banking.

Any suggestion, tutorial, page to read?

Thank you very much

No sound, but here is a video showing how to add custom superelevation to an alignment that doesn't depend on curves.

Not exactly what I need, but the distance of the transitions is usefull.

Thank you

What I can't understand is why when I finished with all the bankings and their transitions stations, when I calculate it changes everything to simple slopes (0% or 4%).
