How to select curves efficiently

I am creating curves to make surfaces.
If you zoom in, you will see that all the curves are double.
It is very difficult to manually erase one of the double lines one by one.
Is there any way to efficiently erase only one of the curves?

you can use curve boolean with delete inputs= yes.

I’d do a handful at a time so you can see which ones fail, because several of them will.

the ones that fail, you may need to redraw as they are identified.

You can try the Seldup command if they are copies of each other.

Thank you so much!

It didn’t work with Seldup…

sadly this file is going to require some tedious sorting as the curves are not dupes, but have many overlapping segments…

curve boolean will be your friend here, but it’s still going to be a fussy, rather tedious fix.

To be honest, it was quite a hassle.
So I ended up going back to Illustrator and fixing the vectors.

that was likely the best way to handle it-
