how do I go about creating tapered fillets between existing surfaces?

FilletSrfToRail can be used to do this in Rhino9. FilletSRFToRailX.3dm (300.9 KB)
In the enclosed file the red curve is the rail. The trick is to make a smooth rail that passes thru the end points of the 0.200R and .0.075R arcs. The arcs are green. I just made the two fillets on the one side and then used mirror to make the other side.
Just for completeness; FilletSrfToRail is also available in Rhino 8.
@Lagom the command is indeed in Rhino 8, but it has been vastly improved in Rhino BETA
Sure, just wanted to point that out, because Rhino 9 is not yet officially/commercially released, and many have to continue using Rhino 8 until then.
Thanks guys; enough help to ask better question(s). unstated in my initial post is the requirement for G2 continuity from the filleting or radiusing; moving air does not appreciate surface discontinuities! finding the needed end radii for a tapered fillet is straight forward; see first included collage. I do not understand how to extract the needed “rails” from the existing surface. see second attached collage. the second nagging concern is will I get G2 continuity and if so with which command? multiple readings of the “help” description for FilletSrfToRail have left me uncertain on how to proceed with a G2 requirement…

Use DupEdge to duplicate (“extract”) a curve from a surface edge.
HUGE Thanks!! eventually I’ll get my ideas for verbs aligned with Rhino’s…
