The curves in the second example are oriented in opposite directions. Flip one or the other in Rhino, or use Curve\>Util\>Flip Curve in Gh.

I’m still not clear on why it’s ok in one instance and not the other because in both examples the two curves have different number of discontinuities. I tried shifting points with slight improvement, but this fix should work.

Hello,

I’m having a similar problem with loft.  
Could you post the .3dm file in a Rhino5 version ? I’d like to check out the solution you guys found

Thanks
