While there have been some differences of opinion between leakers in the past, three high-profile ones have all endorsed the same CAD drawing of the complete iPhone 17 line-up.The drawing shows the three completely different camera layouts expected for the base iPhone 17, the iPhone 17 Air, and the two iPhone 17 Pro models Three high-profile leakers agreeMajin Bu has been the source of a number of accurate leaks in the past, most recently the naming of the iPhone 16e. Bu was the first to report this, in early January.In a new tweet, they post the drawing with a simple iPhone 17 Lineup CAD caption. Fixed Focus Digital endorses this, as does i Ice Universe, who shared the image.We should immediately caution that, even if accurate (as now seems likely), CAD drawings do not give an accurate render of the appearance of the devices, only the placement of external elements like camera lenses and buttons.For example, if we put the CAD drawing of the iPhone 17 Pro Max side-by-side with Sonny Dicksons latest render of what that design layout might look like in real life, we can see just how much you can and cant tell from the former.Notably, we can see the positions of the flash and LiDAR sensor on the right, but theres insufficient detail to tell whether the entire camera module is raised or, as Dickson suggests, split into two separate bumps.Additionally, the red area is not indicative of any visible element.Weve also previously seen more accurate ideas of what the iPhone 17 Air design might look like in real life:Three different camera modulesWhat we can see in the drawings are three different camera modules, left to right:iPhone 17 Air, with single camera in a horizontal bumpBase iPhone 17 with two cameras in a vertical bumpiPhone 17 Pro Max with three cameras in a triangular arrangementiPhone 17 Pro with the same layoutThat does look kind of messy when we see them side-by-side like that, though wed of course expect the case finishes to provide a much more coherent look.You can check out our latest coverage on the line-up and on each model below:Add 9to5Mac to your Google News feed.
