blend profiles along rail curve?

Hi all,

I'm not sure if I just can't find this component but..

does anyone know if it is possible to blend two profiles along a rail curve such that there is gradual transformation between two profiles at the start and end of a rail curve respectively?

Any assistance would be much appreciated, thanks,James

Try Sweep1.
Input both of your profiles when asked for section curves.

Thanks for your reply but that doesn't seem to work unfortunately. I kinda found an alternative way of approaching the problem using the tween curve component and re-orientating the profiles along a curve and then lofting them.

Seem weird that there's not more functionality in this area of Grasshopper as I know you can do the operation I'm after in Revit whereby you simply set a rail curve and a start and end profile.
