Fusion 360 Sheet Metal Model

I need a precise sheet-metal part built in Autodesk Fusion 360. The sole focus is on correct Sheet Metal Design: unfolding must work flawlessly, bend radii and K-factors have to follow Fusion’s rules, and every flange should update smoothly if I later tweak thickness or material.

I’ll share hand sketches and exact dimensions once we start; the material is still open, so please set up editable sheet-metal rules for aluminum, steel, or copper so I can switch between them without rebuilding the model.

Thanks ...
