Here we go!! Big update, I have finally have the 3D scanner setup (built a computer that should be a beast for CAD an anything else I need to throw at it in the future such as a driving sim in the garage down the road), and got the scanner yesterday. Ended up going the route of the Einstar Einscan so that if I want to go with a higher end scanner in the future I can do one of their professional options and not have to learn a new software.

 

Even after only about 30 minutes of setting it up and playing I was able to get great results on the bed side of the pickup so should be able to get a really good body scan down the road an the parts to start the CAD work and even CFD simulations in the future!

 

I have attached an image of what the model I was able to get thus far looks like, and hopefully will spend some time to show it in video for at some-point down the road!

What sort of file do you get from the scan, is it editable vectors and points or just an image that you can use to overlay your vectors etc

Presumably you can import that into something like solidworks to fit weldments and sheet metal parts in

And if you scan it from various different angles how does it know how to line it all up right do you have to put reflective stickers on it as references or something

Always been a bit curious about how that works

All this looks like witchcraft to me 😬

Depends on how you export it, but it is a point cloud based file. Essentially what a scanner is doing is plotting points relative to each other in 3D space, and that is what tie file is (it connect 3 points to make triangles that give the surface).

 

You can import it as a surface mesh to any CAD software and use it just a mesh to design within or you can go as far to create parametric surfaces off of it using modeling software (which is what I plan on long term doing so I can run some Aero CFD simulations on things I plan to do to optimize them).

 

How the scanner lines things up is based on texture or markers. In this case the texture of the stripped panel was good enough but a painted surface needs markers or something for the scanner to track. I have read a cheaper alternative to markers is just putting painter's tape at various angles on panels and the scanner can track that instead of need the reflectors.
