loft with twist problem?

See reference image!

 

I'm trying to model a belt that connects two wheels AND goes around a 90 degree bend.  I tried to Sweep from Profile 2 around to the midpoint (after which I could use mirrors) but it wouldn't accept my rails.  I made a body around the first disc such that Profile 1 is at the tangent point.  Then I tried both Sweep and Loft to complete the body, but I get "inconsistent edge-face relationships".  I tried using both rails, also no help.  without the rails the gets weirdly fat in the middle.  Both Profiles are the same size.  Profile 1 is obv. not on a parallel plane to Profile 2.  Reversing the profile selection doesn't help, either.

 

File is here: https://a360.co/2J3fwat

 

Edit: never mind!  one profile was slightly off-path.  Can't delete dumb thread.  sigh.

Try Sweep with a single centre line rail, and 90 degree twist, for that segment, type join.

If you have to Loft, you need 4 tangent 3d Splines, for the rails, (too hard), in this case as the profile is the same each end.

 

 

Might help...
