Design registration technical patent drawing

My client re-designed a poppet inside a valve used in the mining industry. He required a series of patent drawings to secure the registration which I produced for him. I also supplied a series of 3D graphics which depict the poppet in-situ through a ghosting technique where you see through the product to the inside workings. I compiled these drawings for him into a branded Powerpoint Presentation so he could present to potential clients.
