Any straightforward way to morph a curved duct

[Anonymous]

Hello, I need to draw a curved shape duct-like object.
But in Morph tool, there is no a straignt forward way because the morph refuse to choose to enclosed polygon.....I have to （1）morphor one polygon, then （2） draw again the path, copy and offset the first polygon, then extrude it, the intersect it.....
Or other tools can make it in a straight forward way
