< Depending on what you are trying to accomplish
It was just the fact that somebody ask me "How open a closed curve" :) (I don't know the reason)
So I try and don't the trick for a "simple point" cut ;)
Best solution is to erase a little portion of the arc circle (or any little curve portion) for have the 2 curv's end and move them in any direction :)
