2 .PNG pictures of 2 different parts turned into CAD .STEP files

Hello, Looking to get 2 .PNG pictures of 2 different parts turned into CAD .STEP files for physical prototype companies to be able to create a product from. Product dimensions: Width=2.2inches Thickness=.6inches Length=9inches Weight=4ounces I also received the following email from the prototype maker. Let me know if you can do this and I will begin the gig. Alex, Thanks for the feedback. I mentioned this to engineering, and they reminded me that we need to see anything that is being over-molded with silicone too. So if you are planning on on over-molding a battery or anything else, we'll need to see where they need to be placed in the product. We work in Solid works, and would like to see an assembly file. 1) over-molded -- Process of layering silicone over another material -- for example a battery 2) solid works -- 3D CAD software for design and modeling 3) assembly file -- a type of solid works file which shows multiple components and how they interact with each other to make one product Best, Alex
