Problem with Curve Loft--with their directions

Hi all,

I'm trying to loft curve on the ground surface to same projected curve on a plane that is to be the roof plane. I got most of the loft working, but still having some trouble

but some curves still fails (like below)

here's the loft script

even with the guided curve input, im having trouble :(

im attaching the extracted rhino file and grasshopper file.

Hope you geniuses can help me!

thanks,

Jina

In your loft options, make sure "align sections" is selected.

And if still doesnt work, try something like this:

The align sections option doesnt always work well when curves are not trivial, as well as the flip with guide.

Do you have an example of your issue ?

My definition was trivial and inadapted to most cases.

the definition is a "bit" more complex, but I could not seperate the part I have problems with. It is at the very end top right ;) marked with a big circle. I want to loft always the two triangles and create something like a frame....but I have no luck to do that. maybe you find a way....
