Connection two different sized sections along rail

Hi all MagicMakers! :smiley:

How to connect (loft) this two (red) curves but along rail (the yellow curve)?
Maybe there is some intelligent component that can be quickly done, or maybe you know a quick and smart way to achieve this?

Thanks (17.8 KB)

I already have a solution. I didn’t know that we can connect more inputs to sweep1.
