Hi everyone!

I'm wondering how one can "copy" curves... Say I make an S for example...

so then I want to take the upper left curve of the S and put it in a new object, say to make a "wave" or something coming off of it... what would be the best method to copying that curve, or furthermore somehow "putting" the curve into an object --- sure, I'd think subtract objects- however it seems like it adds unneccessary nodes whenever I do that- what methods are there?

Thanks
