Align sections

Can someone help me to align the sections of these curves?
ps: I know the align section method using the loft option but I’m looking for another method that does not go through a surface in order to have aligned curves

thank you :wink:

you can add a guide curve like this:

thank you :kissing_heart: it works with that but I did not understand the principle of working

without a guide curve it will just flip the curves, otherwise it compares the direction of the curve with the guide curve and if it is matching it will not flip the curve

:pray: thank you so much
