How to convert a twisted surface into developable surface

Hello everyone

I created a triangle profile (Brep) through Sweep 1 Rail then I deconstructed it and cull one of its surfaces. I need two another surfaces. The problem is that as I want to fabricate these surfaces (twisted arc surfaces) by laser-cutting, it is required to convert the surfaces to developable surfaces. This make it possible to unroll it to planar surfaces then use its bounding curves, which are planar, for laser-cutting.
I do not know how can I convert these surfaces into developable and finally planar surfaces?
