For one lobe, without loft, with just the many circles, LINEWEB, curve version, can be applied to the circles.
Then, by selecting all of the circles and lineweb curves, NETWORK will produce a surface, but had slight wrinkles in the center area.
Circular array works, but join does not. Boolean union of the 3 circular array lobes, will make the 3 lobe solid, but with the slight wrinkles still present.
The loft version looks better.
