Hi.  
I have a problem with Dynamo. I don’t want to create surfaces on some curves from the end of the list.  
Loft surface self intersects.

@Anahronis ,

you have to sort your lines f.e. a path

> Good morning all- \*I have searched this forum extensively, for days, so I apologize if this question sounds familiar. I am struggling. I am trying to plot a polycurve along a set of points, using: I can sort by X, Y, Z- but that doesn’t keep the points in order of minimum distance, and produces a fairly sporadic looking set of lines. Maybe I’m overlooking something simple. How could I make that happen? Thank you in advance.

I’m a noob. I don’t get it where to insert the sort and what key

Okay it works.  
It was enough to indicate only the “y” axis to transpose  
Thanks for directing me.
