For those of you looking to create watchbands or cases for the Apple Watch, they've released the CAD drawings for both the 38mm and 42mm versions. And boy they are a doozy.
Jul 29, 2020 To draw an apple, start by drawing a circle and then an oval that overlaps the top of the circle. Then, inside of the oval, draw 2 parallel curved lines with a small circle at the end to make the stem. Size: Measure key dimensions as shown in the manufacturing drawings. Burr: Ensure the burr on both sides of the part is minimal (less than 0.1mm). Strength: Feed the silicone strap through a forehead band and pull with 30N / 3kgf / 6.7lbf. Ensure the silicone strap does not break and forehead band slots do not enlarge. Apple Pencil sets the standard for how drawing, note‑taking, and marking up documents should feel — intuitive, precise, and magical. All with imperceptible lag, pixel‑perfect precision, tilt and pressure sensitivity, and support for palm rejection. Incredibly easy to use and ready when inspiration.

They're filled with 'keepouts' warning would-be accessories designers which parts oughtn't be obstructed, to maintain functionality.
To us CAD-reading ID'ers the drawings provide glimpses of numbers we could only have guessed at. Like the corner details:
You didn't think that those were all one radius, did you?
Or the bottom of the side profile?
While the drawings are provided black-on-white…
…Yeah, we inversed them, for no reason other than that they look cool. Apple movie program.

Apple Releases Apple Watch CAD Drawings
Wow.
How to screenshot on an apple. I was always told by the engineers to measure from a datum point. Are these the actual manufacturing drawings or are the simply a guide for after market manufacturers?.
Also the curve isn't Conic is curvature continuous maybe at 5 or 7 point or something, haven't worked in alias for years but from the looks of it thats what they're trying to show, in automotive I don't think you even bother marking up this curves as you hand the surface data straight to the manufacturer.How do i lock my apple watch. So, why did Apple go through all the trouble of marking down control points for a spline instead of just giving us the end points and rho value for a conic? It'd have cleaned up the drawing markedly.
Those are probably not conics but splines or even better NURBS curves. You can repersent a correct conic curve with a rational bezier curve of degree 2 but you need higher degree to obtain good cuvature continuity and an aesthetically pleasing connection with the straight line. Also I suspect they just dimensioned points on the curve measured at a regular interval, in a way that every interpolation you could build on them will have a desired error with respect to the actual curve used. It's a common practice in optical design for example.
I agree, it's very frustrating.
Most of Apple's products that need cases have conic corners yet their drawings are all straight line splines when you zoom in.It makes getting a really good fit the first time a learning experience for sure!
