The ah ha moment came 10 minutes after posting, so Im gunna draw an arc at the green circled area from the 2D profile of around 6mm in length approx, then draw 1mm coincident lines ( as a rounded corner ) every 15 degrees and then extrude then bend on those vertexes. Easier now Im thinking about it.
I've been working on this A LOT the past couple of days Darryl. I need to take a break from it actually.
I know I can do it with a 24-sided polygon for the bottom hole. The challenge I am creating for myself is I want the hole to actually be 115 diameter round.
I'm curious Darryl, are you going to settle
, for lack of a better word, for a polygonal hole?-- is that the method you're going with?
Being as obsessive as I am, I'll probably have another go at it today. Something came to me last night that might be a way to go.
I can model the "skin" of it easily enough now; but getting it to fillet or unfold is very much my challenge; I might not ever be able to achieve the unfold, other than to do it "manually" in TurboCAD, such as a sheet metal fabricator would have to do.
