Take your existing prototype or parts and reverse engineer for CAD documentation. All CAD is generated using Onshape or SolidWorks with all major file formats available to the customer (.step, .stl, .dfx, .dwg, .sldprt, etc.) Models and drawings are often created for controlling a design going forward, ordering prototype or production parts, and design optimization. With CAD created, modifications to a design can be easily made and "tested", all within the virtual space. This design is shared with the customer before finalizing a concept and handing off all files to take design ownership.
