Join Carl Frischmuth for an in-depth discussion in this video Finishing the frame, part of Fusion 360 Product Design: Lighting.
- [Narrator] Alright, so the next thing we want to do is probably just come in and grab this sketch here and turn it off, so I'm going to find it in the browser. It's sitting in this folder and turn it off 'cause we don't need it right now. We'll probably come back and use it to put more window panels in here. The reason why I was showing you that is so that you can do window panels that are not really symmetrical with the main body. There's been quite a few splits that are symmetrical with the main body, but you can make it look a bit uneven if you use that star sketch to put different planes around.
Make it look a little bit more organic and asymmetrical. I'm not sure about that window material color. What we can do is we can grab polycarbonate clear and drag the color around, and it'll update. So, if I like a bit more of a blue color, not yellow, it looks a bit odd. We'll just double click on that and drag it around to a blue and then we can make it look light, so any color. This is not realistic, 'cause if we go in the form to print out a clear color, it'll be pretty close to white.
But in the model, if you want it to look cool or take some prints or renderings out and show people, then we might want to tweak the color around to make it look pretty good. So, I'm just going to grab that and drag it back to a bit more of a blue color. It also makes it easier to see what part's a window and part's opaque and gray. Alright, so the next thing we want to do is we're kind of finished with the external parts for now, but we want to get back into internal parts and finish those off.
So, what I want to do now is I'm just going to show you a single frame section and then come back here and turn the frame on. We'll go and turn the external parts off and activate that. So, I want to pick a frame section here that's got a little bit of stuff going on. We'll grab this one. I think this is pretty good. Okay, I'll activate it and isolate it as well so that we're looking at it just on time.
Okay, so when we were modeling this before, we really just modeled it and I put some basic fillets on here, not much at the moment. I think they're still sort of floating around in there. I'm going to pretty much come along and we'll review these and modify them. So, add some other edges in here. We can help blend these to different ones. I think, if you'll also remember, I was adding little fillets into the bottom of the lugs. So, part of the finishing off of the internal frame is that we've got to add exactly the same fillet on here as well, which will help round off these to match.
Alright, you can see here there are some other fillets that are required on this part of the model. I want to probably make sure that they're all done. So, with filleting, there's generally a particular order of how they have to happen and sometimes they need to be done in one place first before it makes it easy to do it in another. You can see, as I'm selecting these other edges, some of them are going back to being hard. So, if I come in here and grab all of these, and do it all at once, it will fillet that all off and round off with it jointing nicely.
Actually, I'll keep those 'cause I'll usually want to add some bigger ones up here. We're going to use delete as well to get rid of some small little pieces and make it a bit better. Okay, so we're going to carry on in here. When we've extruded this flat surface and it's left some little pieces in here, which are originally from the other side. What I want to do is get rid of those with the delete key. So, I'm going to take this and knock it off 'cause we can't really add anything useful on here as far as a fillet goes.
We don't really need them there anyway. They're not helping the lug, so I'm just going to go around and clean this off on this end. So, those two on the top there are done and if you flip it around and see if there's any at this end as well, there are. So, grab those and take those off. In here, we'll do the same. In there, in there, and in here. We'll say delete. Then we can use these as a way to add a fillet in that's a bit better radius and help join this into there a bit better.
Okay, so once we've done that we can actually come around, so that's a pretty good size, 2.5, try three and see what it does. Yep, three is good. So I'll leave that on that end and say okay. While I'm at this end, I'm going to fillet the other ones inside here. The reason why I'm filleting with a larger radius is this also helps with strength later on. So, the reason why you'd want to come in and fillet things off is that you can add bigger areas of material like in here to help blend this back in.
So, originally, when this fillet is not there, the amount of material in this cross section here is quite small and quite thin 'cause it all tapers together. So, if we add this and make it a little bit bigger and make it 5 mil, it adds a bit more material there, and also we can fillet this edge and the other one on the other side and it'll add a little bit more extra material around where they join. Okay, so, we'll run with five on that end. We can probably even try to see if we can get away with using these other four edges as well, and adding them in so that we've got one fillet in the timeline below and it's doing the job of rounding off these ends.
If we want, we can see what it looks like at 10, it's probably pretty big. That's not too bad, so we want number 10, which is good. Okay, so that's tidied off, we've added some three mil fillets in there. We'll try and see if we can do that on this end as well. We'll put one in here, one in here. We'll see if three will work and we might not have enough. Oh yeah, we've filleted it in there, and filleted in there. So, we can cancel that and come back to this other one that we've got and then just add these edges into it.
And say okay. Alright, so these other ones here as well, I think this is the one that we added originally to this side. I want to drag that fillet and have it happen last. Then I'm going to grab the end of the part marker, it'll drag it in front of it. It's just a way to suppress it. What I want to do is put some other fillets in first before this one and then let it turn up later. It'll have a bit of a calculate about that. Okay, so drag that into the end there.
I'm just going to grab the end of the part marker and drag it in there to sort of hide it for the minute. Alright, so I'm going to add some more fillets in here. Specifically where I want to add them is this edge in here. We're going to choose them on both sides. I want one there and one on this side, too. I want them to be exactly the same, like the other side here. So I want these three on this side, and then these three on this side. I think, if we've got them all there, we should have, oh that one there's not selected.
Sorry, I want to choose something like three mil and that will add a little bit more of a blend there to help that to get up in that window. We can probably even make that five. See if it'll work. No, little far because it runs up into another piece here. Yeah, that's not long enough to have a five, so we'll say three is good and leave it at that. Say okay. So there's the other three mils here, what I can come do, edit that three, too, and then add these ones on the opposite here as well.
We'll do that at the other end so that all of those corners are covered by the same fillet. What I'm trying to do is avoid having too many fillets in here. You know, if I've got something that's the same size and I can stick more edges and add them in, then I will just edit the fillet. Hold the control key down and it will actually add more in. Alright, so, the next thing we want to do is probably come along here and grab these hard edges on the outside. Click those up, add another fillet that's like two.
See if we can grab these and join them in as well. Yep, so that's good. We'll add this. It leads to another area around here and it doesn't like having it as two. So, we'll probably take those back out. Alright, so the other ones are okay. We'll make those two. You can't reveal this one. What will happen with this one now, is it'll say "Hang on a minute, there were some edges I had here that are gone", and it'll either blend them in with this existing one, or they'll want to update.
So, I think 'cause there's a tiny bit of edge there, we may just come back and reselect this as well. There's another hard edge still sitting in here. So, let's come back and hide that again, and add these into the two mil fillet that we just added. We'll add these edges in. We'll see if they'll all fit in there, there will be another one on this side. Then come back up in here, grab this and this, alright so all the other ones are happy.
So, we'll say okay with that. Drop that on there. Yep, these edges have changed, so it'll probably not be very happy about that. So, we can just say, yep. Then we'll drop those. Then select this. Now that there's a lot more fillets in there, see how it runs in one continuous edge up and down. On this side, it'll be the same thing. We'll have one continuous edge that runs all the way down from one side to the other. We'll just grab these and put them in as well. Put that back under two. Try 1.5.
Nope, okay, it won't let me drop these out. Then it'll probably go back to two. Say okay. See in here, if we put these in at two or at some other amount, .5 or something like that, they'll still fit. Try it at one. One works. 1.5. Yeah, so 1.5 is alright. Okay, from there we're pretty good.
What we want, we can come back to this one and add maybe that in as well. The same with this one. Okay, we're going to start adding some small little one mil ones in as well. So, if you can keep the fillets all sort of grouped together based on size, then it means there's less of them in the timeline. It's a little bit easier to find what is grouped together based on their size.
So, we'll put that in there and see if it'll go with one and it should round off the edge of that, make it .8. That will work in there. Sometimes when you get multiple edges all converging together, you need to actually come in and select even the little bits like this. Probably drop that little edge there and this one as well.
Put it back to what it was. Sometimes this needs to happen first and then you can come along and add another fillet later and it'll blend that corner much better. Okay, so we've got the sides of that rounded off a bit better. We've got those done so we'll say okay to that. Alright, then we'll come in and add some more fillets around here. One here, one here, and then some more over there. See what we can do with that. Two is not really good. One's okay.
1.5 is alright, so run with that. We'll come back and grab these ones that we were trying to do before. We tried them at two and they didn't work, so we can probably drop them in at 1.5 and that might be alright. Drop them in at one. They're okay. So, now there's probably a bunch of these small edges. We probably just want to come along and collect them up. On this side, and on this side, make those .5 and they should work okay.
Add these in as well, it'll blend that hole together and make it look like a little weld. If we come back in here and put control down and click these in, it'll be a bit better on that side, and then there'll be some on the other side, too. We'll want to add those. Move the model back into view. Alright, then we'll add these guys in as well. I think that's good. Alright, so I think that pretty much covers most of the filleting that we want to do there. I mean, really it's just to try to round the part off and in some areas, we're adding extra material to help give it more strength and just to make it look a little bit more clean.
I think the final thing that we need to do, really, is to add some of the last little things we're talking about which was add these little .5 rounds on here. So, we'll do that. I think this is pretty much ready to go and drop it into the printer and print out a prototype. Mainly what we're going to do now is go ahead and do similar sorts of things to each of the other pieces in the model. If we go back to internal parts, there will be some areas in here where we might want to add some more fillets as well, you know, join some of these things together.
You don't need to go too crazy, but I think some of you are in places where you want to have a bit more strength. Specifically, probably, on this hidden part. You can come in here and add fillets in to these little parts on the side here to help blend them in and roll that up the side. It'll probably run into that edge and stop. So, we're going to go ahead and finish those off, and we'll catch up with you in the next movie.
Once you've mastered the various approaches covered in this course, you'll be prepared to approach other complex 3D design problems where the old solutions don't cut it, and you need to create new, complex forms to get the job done.
