How can I unfold or project this surface?

I've made a simple surface as a composite part (before that app got removed lol). But anyway, its just a surface and I'm looking to unfold it so I can laser cut it. But its impossible to find a tool where I can unfold something. I'd appreciate any help. 

The only one I can find is in sheetmetal but this is not a sheetmetal part.
