Fusion 360 surface patch of spline

[sschroer3]

I have a 3D sketch profile (1 complete spline) I'm trying to fill with a surface patch (to then offset and boundary fill). The spline profile is essentially the same idea as the stitches on a baseball, but when I go to patch with the spline as the boundary edge, it always fills the wrong half of the profile (think one of the white halves of the ball, but I want the other half to be patched). I tried adding additional splines to use as interior rails, but then the patch fails b/c it's still trying to patch the other side. Any suggestions? It's a tricky problem as filling the other side is a valid patch, but there's no option to swap sides of the spline or something. Thanks!
