How to transform interseccional lines into objects

[Aigorlaxy]

Hello! I have an vector PDF with continuing lines that intersec each others to form puzzles.

There's a way to take all this lines and transform then into every single puzzle piece, like that?

I want each continue line to be a puzzle, not just a line;

Take a look at Live Paint or the Shape Builder tool.

Select everything and use Divide in the Pathfinder panel.

It worked, but now I have double lines. I need to exclude double lines 😕

Any idea how? Its a vinyl cutter, so, I need just 1 line.

You cannot get pieces without also having double lines.

Are you sure you want individual pieces if it's for a vinyl cutter? Wouldn't you just want it to make complete across/down cuts of the material, as in your first image?

As Monika said, you can't have individual pieces without double lines, otherwise how could neighbouring pieces form complete shapes?
