Curved stairs on a curved deck

[cbwhitebu]

I am trying to figure out how to add curved stairs to a curved deck.

 

I would upload a picture but the upload keeps failing.

I have tried adding decks in concentric circles but so far I haven't been able to make that work.

 

The stairs need to match the curve of the deck edge.

I managed to upload the picture of the deck!
