Very cool,

I've been starting to use ARKit from a different angle.

Usecase - test out 3d designs of replacement classic car parts I'm manufacturing as a side project.

While crude right now, I think this sort of stuff is a game changer - I'm regretting not picking up a lidar enabled 12 pro instead of a 12 now to do better scanning and placement. I guess I'll pick up an ipad pro when it's upgrade time on that front.

Here are two quick videos I threw together:

Workflow:

- build 2d models in solvespace (https://solvespace.com)

- export dxf to fusion 360

- convert dxf to sheet metal

- bend sheet metal in fustion360

- export obj from fusion360

- save obj file to icloud drive

- open obj file in AR Viewer app (https://apps.apple.com/us/app/ar-viewer-augmented-reality/id...)

Sidenote:

There still isn't a replacement for physically printing the parts before I have them laser cut out of metal. I 3d print models and test fit pieces as intermediate steps too.

Really excited to see ios developers digging into ARKit more, I'm excited to see what else is possible here.

If you got the iPhone after November 10th they have an extended holiday return period https://www.apple.com/shop/help/returns_refund

Yep, I'm in that window, but availability of the 12 pro is pretty bad and it's not that painful in the grand scheme of life to warrant hunting one down haha. Regret, but not that big of a regret :)

Well you've got another month to think about it.

Personally LIDAR on the phone sounds a lot more useful to me than the iPad, and I say that having a 2020 iPad Pro.

Knew I was going to upgrade my SE to a 12 Mini with no LIDAR (based on rumors) so I sprung for the new iPad instead of looking for 2018s on sale. Nice to have one device with LIDAR to play around with, but it's super awkward to wave an iPad around to scan things.

More than anything else, I think it was pushed out as a developer kit to get the hardware in people's hands and apps ready to go before it hit the mass market with the iPhone 12 Pro.

Not sure if it'll work for you but I was successful in getting a same-day courier for the 12 Pro for $9 where shipping it would have taken a month.

Thanks for sharing, hadn’t considered something like this, very interesting to see!

Would be cool if the object-matching tech (this[1] + more machine learning?) in ARKit was advanced enough that it could recognize a car seat or dashboard and place things automagically.

How are you enjoying solvespace? I wanted to use it for a project but I found that I was completely unable to use it for integer-parametric designs. E.g. if I wanted 10 of something stacked end-to-end, I couldn't figure out how to do that without breaking the solver.

[masonhensley]

I like it more for 2d work.

I haven’t gotten into the groove with it for 3d workflows. I probably need to do some more tutorials for it on that front.

Pretty cool application. Exactly how accurate is the AR + Lidar combo when it comes to fitting? For example, if you 3D print a car part after sizing it in 3D, does the printed product match up?

[masonhensley]

I haven't been able to scan the interior (transmission tunnel in this case).

But that would be the general idea. Scan interior - 3d model parts to fit in that scanned world - 3d print/CNC cut those parts to fit.
