Hi Antonius,
Yes, not the machinist, but the jeweler! this is only about 1/4" - 3/8" in diameter! The part will probabaly be cast once teh design is finalized. yes, good point on teh undercut. Hadn't really thought of that. So, a 'cone' for a cutting tool is acceptable, to manage the undercut. (And due to teh size, the 'flat' at teh top of eth undercut will be ... small.
Either image you've shown is good.. Your first paragraph is interesting. Can you elaborate a bit more..
>>Your fabrication method is accurate. The sweep profile is pretty easy to accomplish, I suggest using a Wrap feature and have the sketch understand the pi*d characteristic to control the angle on the face. This is pretty easy. The wrapped curve should understand the normal, but it not, you may need to have a "shadow" curve that is offset from the 1st to manage the normal. Sharp points on the inside is easy with a minor caveat depending on the tool shape.<<
I assume I've done the wrap feature, and the pi*d characteristic needs a bit of an explanaiton. And a bit of guidance as to how to 'punch' a solid to follow [cut] the path.
I think I get it, but understanding it & doing it in Creo are sometimes two different worlds!
