Back in 2007 I was an industrial design intern working on splitting a 3D modeled car body into separate components, for creating carbon fiber molds. Back then they used a hideously expensive 3D arm to only create a point cloud rather than a stitched mesh, based on the axial angles of the arm. Forward 16 years and I just picked up a very accurate handheld scanner for car body parts for 1000 Euros.
7:15 one helpful way I’ve used to find the scale factor is to take the real life (known) measurement and divide it by the CAD measurement. That should give you a quick and accurate scale factor ratio for your design. In this example 95mm/1113.648=0.08530523.
Want to give 3D scanning a crack? You have a TON of App options and Conner has listed a few on the forum to help you out: www.hpacademy.com/forum/practical-motorsport-cad-design/show/smartphone-3d-scanning-apps
Scanning can be really useful, i have used my 300usd creality lizard to make some car stuff, precision on reasonably sized stuff is impressive. The big time consumer is the cad work afterwards.
If you've got a solid phone and use case for this you might as well make the most of it. A commercial setup is always going to be more accurate, but it is pretty amazing what we can do without one these days compared to just a few years ago! - Taz.
