Beauty through embellishments and fillets

“

- [Instructor] Okay I've loaded up the 6-12 example file. We have a very nice little headphone mount here with a retaining lip, but, you know? It doesn't really look very nice. So let's make it a little bit nicer. As I've said before, everything around you has little touches that make your objects not scratch you or hurt you, but also just be a little bit aesthetically nicer. The way that we can get that is through the modify and fillet command. And we're going to add some fillets. Now fillets are for aesthetics, but they are also for a specific function. Both modify fillet and modify chamfer can do this. So what fillets can do, what I want you to do is scroll in and click these three edges. That looks like a good selection. We have an arrow coming out of it. If you drag this arrow up, you're adding a fillet. Now you can drag it up so far that Fusion starts to give you some errors. You can see right here at 18 millimeters, you get an error. So you want to drag it up not too aggressively. That actually looks pretty awesome, but it's not what we want. Let's add a 2.5 millimeter fillet. Now notice, the difference between this right here is that this is a stress area. When the headphone is down, it's going to be pushing on this arc and it's going to be pushing at the bottom of this into the wall, but this will also be a stress area. The fillet has made this area filled with a little bit more material, made it a little bit stronger, and a little bit nicer for the headphone to slide in there. Now, we didn't do this on the other side and I want to show you how you can fix that. If you go back into the fillet command, you see that we can do multiple different selections. So you say okay I want to add to this fillet by clicking on this edge, wait, I can't click on this edge. The way that you do that is you hold down the control key, or command key on a Mac, and you see that, as I toggle the key on and off, the fillet actually goes back to its component edges. If I keep the control key down, I can now select more edges like that one and that one. Now let go of the control key and zoom around, hold down the control key again and select my last edge. It's all in this same command. Now we can add some more. Maybe I don't want to have this new fillet that I'll be creating at 2.5, so I can click this plus button. We are now in a new selection and we can click again. So I'm going to click on there, there and there on the inside of our little retaining ring and on the top sides as well. So essentially anything that is facing and touching where our headphones are going to be connected. And I can drag that in. I want this to also probably be around a 2.5. That looks a little bit nicer. Now notice we have this hard edge here and hard edge here. We can go back and edit the fillet, but if we want to use what we created here as another input to a fillet, we can start a new fillet command and we'll be using this curved geometry we created in the previous fillet command to create curves on curves. So as I drag this in, I can only do a little bit here. I'm going to say 1.5 for that. We've now created a fillet on top of a fillet. Now you can go through and change this. The goal for fillets in this is one, for strength, but two is anything that your hand might touch should be filleted. Like right now, it's pretty guaranteed that your hand may touch the edge. You would want to fillet this outer edge. This interior side you might also want to do, but for different reasons. When you filet this inside of here, it changes from a very pointy shape to a much more elegant one. This is nothing except aesthetics. So now as I select these, maybe with different fillet radii, I can get a very nice effect. Now obviously when 3D printing this will take a lot more material, but it is a very nice effect on the inside that now those sharp points that were there, these curves more match the curves that exist on the outside of the object. It's just an aesthetic choice, but it is something that you might want to consider to unify your design. I might do a couple more fillets on the front of these. If you click on an existing fillet you'll be able to match the radius of those, and I'm not going to fillet on the back because I want a nice solid connection against the wall. And I don't really need a fillet on the back. So you should keep going around and doing this and please remember that if you separate your fillet commands, in this case, we are now able to fillet this entire tangent edge that was created from a previous fillet command where we were not able to do that before. So if you combine fillets with other fillets you can get some very nice effects once those curves are now tangent to each other.
