I'm tasked with creating a scale model of a truck cab.  It doesn't have to perfectly match the real world part, but should be similar.  Likewise, it needs to be designed such that a typical sheet metal shop will be able to manufacture from the flat patterns that I provide.  I'm hoping to gain some knowledge and get a better understanding of how best to approach this project.  It's a real world deliverable, and I want the customer to be impressed.  Many thanks in advance!

To be clear, I am struggling with the various sheet metal tools.  Adding rips and bend lines seems like a futile task at this juncture.
