All 3D Engineers designs can move from the virtual to the real world. There are, of course, innumerable designs on the web that are truly fantastic. However, most lack real-world dimensions, the detail required for production, any attempt to meet legislative requirements for road use and the class of surfacing required to turn a concept to reality. And then the thorny issue of tooling for production crops up.
3D Engineers would encourage you to watch the slideshow on this page to prove that the designs created have made it into reality and are worthy enough to be reported on by the most prestigious of automotive magazines.
What you see is a tiny fraction of the output over the last decade. Original, historically sympathetic or faithful re-creations of cars are all possible.
It is also possible to place a “virtual human” within your car, tailored to your size, to check the fit.
