Learning fusion but need to make 3D model of bone carvings for cnc router, of jewelry like items, but can’t find a you tube video to do c850 or top picture. Anyone have a link or suggestion..  thanks

Do you have a physical item? If so, you could bring it into F360 as a mesh.  You could scan is using a 3D scanner of create a 3D scan by taking a lot of photos using a standard camera.  Once in F360,you might be able to reproduce the object in the sculpting environment by using the mesh as a mold for the scupt. Another option would be to take photos of the object you are trying to create and import them as wallpaper on the associated planes and them use those are a guide to create the design using standard parametric design techniques.
Let me know if this is in the line of what you are interested in.  There are videos out there showing each of these techniques.

i don't really keep up with tutorials, can't help you there.  here is a quick example shows one general approach.  the trickiest part of this model is the twist at the top.  you can't make a body that crosses back over itself in one shot in fusion, so you have to make it in 2 parts and combine them.

feel free to ask questions.

Something like this isn't very complex to do in the Solid workspace. Just three sketches, a couple of extrudes, a couple of face moves, a pipe and a circular pattern of that pipe, a couple of fillets, bingo done. But of course, it's very symmetrical and precise. To get more of that hand-made variation you'll have to get more creative with it, or move into a Form/T-Spline instead.

But at least maybe this will give you some ideas. File is attached below.

No, I don’t have the actual piece, I have thought about purchasing some examples and that conversion might be interesting.

That’s pretty neat, I’m not sure what you mean about doing the twist in 2 parts and combining, but it gives me something to try.

@laughingcreek  I'm glad you also posted a model. It's fun for me to compare/contrast our various approaches.

That’s pretty cool and a neat rendering, I’ll play around with some of hints and see what I can do. I’m sure I’ll be back with more questions. 

thank you.

He means that Fusion won't allow you to create a body that intersects itself, and since his twisted loop DOES intersect itself, what he had to do was model half of it in one operation, and then the other half in a separate operation (or perhaps just patterning the first half around 180-deg) and then combine/join the two bodies into one.

Can you open the files @laughingcreek  and I have provided for you? Do you have enough experience in Fusion to look through the timeline of steps taken, look at the sketches made, and deduce how the shapes were created?

Our intent in providing you with those files was exactly that...so you could examine them and maybe have some "AHA" moments.

Yes, I finally had a chance to look at these files in detail in my office.  Very interesting and helpful.
