How do you edit the Isocurves on a curved surface?

Hello,

I have managed to panel my geometry along my curved surface, with only one problem left which I can't quite resolve. The way that the original surface was made in rhino (by sweeping curves) has left its Isocurves at an angle which isn't perpendicular to the top and bottom rails. This in turn is throwing my panelling off and distorting it so that each panel is leaning on an angle of +-30 degrees.

(The first image below shows the isocurves all leaning and the second shows how this distorts my panelling.)

Is there a way to straighten up the isocurves on the surface so that my panelling is no longer distorted?

Please let me know if I haven't made myself clear!

Thanks in advance,

That is amazing - Thank you so much Mkr! It's exactly what I needed, I'm very grateful.

I think it's easier to make all this manually in the Rhino using NetworkSrf with two straight sections near the ends.

Hi MKR, thanks for the tip! I did try that but networksrf gets rid of the kind of curved fanning shape in favour of a straight profile.

I'm having another problem similar to the one I had last time which you fixed perfectly and I wonder if I might ask for your help again? If I should create a whole new post then that's fine - can do so!

The problem now is that I've just extended the end of the shape, and the geometry is kind of bunching together again, I think I need to move the isocurves like last time, but I've tried fiddling with your script and have had no joy simply moving the problematic curve towards the fanned end of the shape.

If you could offer any advice in how to stop this bunching up, I'd be very grateful! Just a reminder that I'm super new to grasshopper so apologies that this is something I should probably know how to fix by now.

Thanks a million in advance,
