Loft troubles on spiral rail path

I've been initially thinking, it would be an easy task: Lofting along a spiral path with only a start and end section.

 

But try for yourself:

- Loft -> 1st Sketch (d=40) -> 2nd Sketch (d=100). Preview switches between the shortest distance, Selecting the spiral as path doesn't have any effect.

- Loft -> 1st Sketch (d=40) -> 2nd Sketch (d=70) -> 3rd Sketch (d=100). Preview and result is unuseable, rail selection results in failure.

- Loft -> All five sections. Result is ugly shape, no rail selection possible

 

With a similar sample I've seen the patterned occurrences of the workplanes show up tangent to the spiral path, instead of normal placement. I didn't see it here, but ..

 

File is 2015. With EOP down, a solution with a drafted sweep can be seen. But I'd like to see my subscription fees used for improvements here. I don't really need these minor changes in colors and rendering, and other gimmicks.

Yes. Shame on me.

:smileysad: Perhaps I've played with this too long.

 

Thanks

It's not just you, I've had troubles with lofts for while.  Seems the key is the order you select things.  But that doesn't always work either.

 

Glad it's what you wanted and works.
