I need to create a cone for a project but I can't figure out how to make it.  Any suggestions?

Ah, yes. Trim Tool, my old friend.

Looks like a colonoscopy staring back at the doctor.

You still need to convert from a Surface Body to a Solid Body.

Did you find a solution to the 9mm thickness? Multiple lofts would also give me better accuracy, since loft from start to finish caused the adapter to become 5% too big in the middle.

 

Studies in multiple lofts:

A. Using all the ring to loft. At least is would make an interesting vase.

B. This one has potential. I had to skip the two last sketched rings before the quarter arc. But it has a little pot belly.

B. It loooks smaller but is also wider.

B. Still not satisfied with the shape. That pot belly needs to go! 😛

 

C.

This one has potential. And the middle ring is controlling the volume to not become too big. But something makes it arch backwards at the top.

 

C, Yeah, no...

I have an idea that I will try later today, but I am still confused by your pie shape attempts.  To me that doesn't look right.

Above are my attempts at controlling the loft. But it turns out that it has the more natural flow if I just loft the start to finish.

I tried Stitch, but could not get rid of the yellow surface, and thicken did not work. Then I tried Patch on the open holes, and Stitch again, but now it is a bit too solid. Can't get it worse!

Back to the roots. Starting with the leg of origin. Create> Thicken. Then pick A surface of the leg - because after lofting a circle to a quarter cricle it will have several surfaces that are individually selectable:

joni_lundberg_3-1762199863773.png

Wouldn't that have been amazing if it worked... Now it it is full of jagged edges.

 

Doing the same thing again, but not selecting the three surface individually. My monster of a PC was struggling for 45 seconds, but we have a wiener!

joni_lundberg_4-1762200119617.png

Except, the hole imploded.

joni_lundberg_5-1762200256203.png

Interesting idea of thickening. 😄

It must be a bug in Fusion. I tried it exactly the same way and it worked.

joni_lundberg_8-1762201037640.png

Okay, I sort of knew it would not work to thicken and THEN use Circular Pattern x4.

joni_lundberg_9-1762201225114.png

 

Trying to thicken after circular pattern did not work. I think Fusion is saying that this is full of holes and will not work. So I should stitch, patch, stitch, and thicken, which did not work. Back to square one.

Can you Shell and remove the ends?

I never used Shell. I learned Fusion a week ago.

I think I was just doing a poor job stitching. This time it worked. All I needed was to stitch and then try thicken again, and it even created a nice solid body for me.

I am not sure what you meant with Shell.

To manufacture it with as little sanding as possible, I started thinking about having the middle part cut out in CNC, with a pattern like on a geodesic dome, despite its irregular shape. I presume it involves unwrap in another software, but first I need to make the triangular or hexagonal splits.

Do you know how to do this?

Shell is a CAD function.

"pattern like on a geodesic dome"

These are planar faces.

Is that how you want to manufacture your design (planar faces rather than steamed and bent wood)?

I think hexagons will be the best. It will keep the look and properties of the wood. And would not require months of sanding. A CNC would not have trouble printing them.

Voronoi Add-On worked wonders, but the shape is leading to some very artistically interpreted hexagons.

I ended up with not hexagons at all, and even so, I would need a lot of grinding to have it look smooth:

The above piece I took out is one of the better looking pieces.
