Fusion 360 | How would you model this ring?

[@Fusion360School]

Trying out the "river rubicon" environment here to reduce the strain on my eyes. Hope that this does not affect the overall presentation. Let me know whether you prefer the standard white environment or this.

[@CelticOneDesign]

I use the same environment. Lowers the strain on these 864 year old eyes. :)

[@larsord9139]

I didn't even notice the "new" environment. So I watched again and I think I like this one better. But whatever is best for you. Oh. as usual a great "tutorial"!!!

[@smorris12]

I didn't even realise it was a thing. Might change mine as light items on a white background is quite hard on the eyes

[@smorris12]

Excellent, as always. But I wanted to say that i was ahead of you every step of the way through both solid and surface models... I'm not boasting; that's a testament to what I've learnt from your videos. And since I've never really watched anyone else's videos, that means you're entirely responsible for what I put into practise in Fusion. Cheers!

Some nice and clean modeling there, as usual. I have some comment though, since this is most likely a shiny surface and purely ornamental piece, I think it would be more appropriate to use G2 continuity on the loft, as reflections will have a more pleasing (smooth) appearance this way. Also, I think it might make more sense to prioritize a round hole, and so extruding the hole, then project and offset to create the flat edge makes more sense to me, but this is just nitpicking.

[@Fusion360School]

I went back to try G2. It did slightly improve the smoothness. However, it still slightly creases up near the corners of the square. I wonder what can be done to improve this.

[@2testtest2]

The sketch fillets are also G1. Maybe replace them with a splinter and use smooth constraint? Or "cheat" and don't put the fillets in the sketch, but extrude a solid body, and use G2 fillets on it. Then you have a G2 face that you can loft to.

[@2testtest2]

Just tested both of these methods, and they do work. for the G2 fillet, use a weight around 2, and large fillet "radius". Similar for the spline method. Oddly Fusion insists on putting the seam off center, resulting in a slightly A-symmetric Loft. Not sure what that is about.

Incredibly helpful. First video I have seen from your channel and immediately got my sub!

[@DanteEhome]

Clean as always. Now think about if bottom needs to have same thickness everywhere.

[@Fusion360School]

You are right. I could have simply extruded a circle. I am too used to creating constant wall thicknesses everywhere!

[@Chaphasilor]

I'd prefer an extruded "intersect" instead of two extruded cuts for trimming complex bodies like this. Just a personal preference. You could use the sketch you used to trim the surface bodies (with slight modifications) :)

[@piranin666]

thx!!!!!!

[@CoryCharlton]

Curious why you discourage the use of fillets in sketches? Do you have a video discussing this?

[@2testtest2]

I can not answer for Fusion 360 School, but I too avoid putting fillets (and chamfers) in sketches whenever possible. Unless otherwise required I prefer to have my chamfers and fillets all the way at the end of the feature three. The advantage of this is that both the sketches and geometry is generally easier to work with and change when you don't have to deal with fillets and chamfers everywhere. It can also be advantageous for performance, if you have a complex model, to be able to disable the fillets and chamfers while you work on the model.

[@larsord9139]

One of the main reasons is so the fillets or chamfers are available in the time line for editing, suppression etc.

[@Fusion360School]

Fillets in sketches tend to break any existing constraints and dimensions. They also make it harder to adjust sketches down the line.

[@CelticOneDesign]

@@Fusion360School I will have to remember that. I have a very bad habit of doing that. Still learning Fusion 360. I am still treating a sketch as a drawing. I need to quit thinking that way. A sketch is only to get you from point A to point B and not from point A to point Z.
