Technical Problems SketchUp

Hi, I need to laser cut this object therefore I need the true dimensions of the 3d curves. Is there any way I can like unwrap or flatten this object without compromising its true dimensions?

Flatten? Or unfold?

You could use an extension such as Flattery to unfold it and lay it flat.

Thank you, but it doesn’t seem to work. Or am i doing it wrong…

It works, but because of the curved surface, it will probably look different than expected?
