      Doesn’t matter, the point where stem and dimple are deepest and encapsulated would have same vector direction initially. Topology doesn’t need to be cylindrical to have vectors

        I don’t have a dog in the race. I just think you are two big dorks and I love this discussion. I want at least a 20 minute YouTube video of the correct answer and why the other is wrong!

          Well you are in luck. No video but images of analysis. Hedgehog plot of normal vectors, they converge to flat at stem base. Hard to see since the stem/dimple share space.

          Confirmation of immediate angle at stem base

          Slope plot. Green being 0 degrees from up vector.

          Dimple hole showing its not a cylindrical stem

          Stem slope, green being immediate 0 vector

          I’m on a trip so won’t have access to my CAD analysis tools, so no video I’m afraid.
