change orientation of a closing point

change orientation of a closing point

(OP)
Hi to all, I am trying to create a script that will run in CATIA and will take several splines from a geometrical set to create a loft (multi-section surface). My problem as you will see in the picture attached is that the vector of closing point.3 is in the opposite direction. I know how to invert it manually inside the loft, or invert from the beginning the specific spline. What I need is a script that will check all the splines and print the values -1 or 1 depends on the orientation. Or something that I can use to isolate for example spline.3 from the rest 200 splines.

Any help will be great
Thanks a lot
