I've been reading through this thread - resin kits, necessary cars, etc. It makes me wonder about the breakdown of a manufacturer's costs. For a manufacturer of injection molded styrene cars, how much is spent developing CAD drawings in HO scale - would a manufacturer be appreciative of well done drawings if a hobbyist generated them and handed them over gratis?
While I'm not claiming the ability to create such drawings, I wonder what it would take to be able to produce something useful?
For a few months I've been messing around with scale 3D drawings of prototype cars I've measured. I've sent the drawings to Shapeways to generate HO parts. I'm not really keen on what I get back - still too course resolution for a lot of modelling needs, although there is potential. But it makes me wonder - if I have fun creating drawings for that limited purpose, would they be of value to a manufacturer? Or puting it another way - where would they have to be different to be useful to a manufacturer? For example, if I knew more about draft angles, I could build them in. I'm sure there are other technical requirements I've no competence to even assess.
But it makes me wonder - would useful CAD drawings substantially reduce a manufacturer's costs and make some projects more viable?
