Changing planes, or rotating planes to presumes a varies slope

Hi Experts

I am trying to learn GH for another concept.
i am trying to super elevate a bridge deck so i can assign super elevation slope range from 0 to 3.5% from start to middle of the given curve unnamed.gh (7.9 KB) Untitled.3dm (28.8 KB) and then reverse back from mid of curve to end for 3.5 to 0%.
just needed the concept to get it going.
A bit tricky but not impossible.

Best Regards and have a great day.

Not sure this is what you want, anyway check this…

Yes. its similar and Thanks lot.

More obvious when display something like this…


Slope_reV2.gh (13.4 KB)

Well in real life we use a Gauss distortion instead of some classic one (Sin for instance). This yields correct/smooth “transition ramps” (but in big bridges this gain is rather marginal). See attached as a concept demo and if required include the Math used in some GH solution vla native components.
