I'm scratching my head on this one

 From:  twofoot
Hi folks. Perhaps I am "in too deep" to see the obvious solution, but I am sure it is waiting to be found. So... I'll ask the group if anyone can figure this out and prod me in the right direction.

I've attached the DWG file I am working from, along with the Moi file I have done so far. For the life of me, I cannot figure out how to sweep/extrude/force the spokes of the wheel to be created using the proper outline.

Any suggestions?
