why is the LOFT so messed up?

I got two sets of lines and tried to loft them up to make a blinds like effect, but the lofting is just so messed up, some of the vector directions are totally different. please see the attached jpg file.

does anyone know how to flip some of the curve directions within a list and not disturbing the index order of that list?

The curves are in different directions and need to be aligned before lofting. Use the Flip Curve component and input the first curve as a guide so that only curves in opposite directions will be flipped.

thanks so much, for some reason it doesn't work for me, but I'm gonna keep trying, i got the feeling that you are right.

one more question, (see the attached screen shot) do you have any idea of what going on at the tip of these lines?

here is my problem: say I got 10 lines, and the no. 2, 5, 7 need to be flipped, I did exactly what you did in grasshopper, and no.2,5,7 did flip, but the rest of the line reversed as well.

why is that?

all right, I get it, in my case, I need to reparameterize them......

thank you so much, literally save my life....

I've got similar problem with few closed curves. Even though that i flip them i gives the sam wrong result. "Reparametrize" option didn't help. Anyway, what "Reparametrize" option does in general ?
