Well, I've used a few different methods in making the cone base, which I can flatten if it wasn't for the star nozzle at the tip. You'll have to excuse my laymen terms here when I explain the methods I've used.
Apologies if it seems a long post!
The first way, I drew a circle, extruded to length as a solid, drew another circle inside and used the cut extrusion both with the taper.
The second way, I drew out a side profile like triangle, revolved it round on its axis and used shell method to hollow it out.
Both of these, I couldn't seem to flatten.
The method used to flatten it, was when I went back to the circle method. But, approached differently. I made the base circle, offset a plane above it at the desired height of the cone and drew another circle. I then used loft tool, to bring them together. I then used the thicken/offset quilt method to hollow it out to desired wall thickness required. After that, I converted to sheet metal, again, setting the parameters. I then created a point in work feature ribbon, across the plan that cuts through the centre, lengthways across the cone. After that, I used RIP, which was successful in giving me a flat pattern.
In regards to the tip, I drew out a 12 sided polygon, centred to the top face (circle), and convert each of these to construction lines. I then create my star using this as a guide. Using line, and joining every other point, and using the trim tool afterwards to make it one single shape.
This then gets cut extruded into the top face of the cone.
Now, the one with the sharp points above, was left, at just the cut extrusion, where essentially it cuts through the wall at a taper, where as the other one, I didn't cut it through the wall as much, when then left me with non-pointed tips, so I created a plane above, around 5mm and lifted each tip face to a centre point I created. These points in the end product are the be bent as required anyway, so straight up, to the centre, etc, doesn't really matter, so long as I can get them with a point on.
The issue for me, seems to lay, with not being able to make a cut, up and across the tip. However, I'm sure there is a way, I just haven't found, or discovered a work around for it yet. 😂
I have tried drawing a line, and using the split function, that didn't work. I also tried rip method on one of them, that crashed inventor and I lost the cone I didn't save (with the lifted points to the centre), I've even tried drawing a 0.1mm thick rectangle across it and using cut extrusion, but that didn't work either.
(Also, not sure how I've made a half post, and then a full post, but I can't find a delete comment option. 🤦🏻:male_sign:)
