Sweep 2 rails closed curves

Hi there,

I'm trying to sweep 2 rails along these curves but it doesn't seam to be showing up. I looked at a few other discussions about this and the solution seamed to be about flipping it or identifying the 'beginning' of the curve but I'm not sure what 'flipping' means and these are closed curves so I'm a bit stuck.

Any help would be much appreciated :)

Your curves seem correctly oriented.

Try to reparameterize your rails and use their Sub Curves with domain 0 to (1-tolerance).

For example 0 to 0.9999

On screen you will see a gap, but it should not matter.

You can also just use Planar Srf
