Creating surface from multiple circles and a curve

Working on some tubes for some narrow diameter airflow. I’m wondering if there is a way to create a surface from a variety of off axis circles, and a curve that flows through them. The diameters of the circles are not all the same. The result will be mirrored on a vertical plane down the line created by the centers of the two circles on the left.

If you have a solution that includes Grasshopper, that’s totally fine. I’m happy to bake small parts of this into the final result.

Hi Kenzan - Sweep1 should do something here - I don’t know that itwould interpolate the same way as airflow though…
I exploded your curve and did this in two parts - the long curve and the two smaller ones, joined. Is that what you are looking for?

Yea! that’s perfect. I tried this earlier and did not get good results. but Thank you, Sometimes you go all the way around to get back to the solution.
