In this video, we'll make Design changes for manufacturing. After completing this step, you'll be able to; use Delete to remove fillets, modify design parameters, and use chamfer. In Fusion 360, we're going to get started with gear housing front cover only. We're going to take a look at this design and what we're going to be setting it up for manufacture. As we look at this design and we take a look at some of the details, we notice that there are some areas, counter-bores, there are chamfers, there are other things that we really need to take a look at and see if they are required in our manufacturing model. The first thing that I want to do is I want to take a look at this backside. Now this is going to be the exposed side that I'm calling it the backside because all of the non-critical features are here. These are simply areas that are giving us a wall thickness to hold onto the bearings that are going to get placed in the design. What we really need to consider is in the final design, is this an aesthetic thing or can it be modified to simplify a manufacturer? The reason I say that is because with all of these features on the back side or this side that we're looking at, when we machine from the other side and we get all of the critical details such as the areas for the shafts and the bearings. Well, the rest of it is really just cosmetic at that point and we could machine this entire part from one side. If that is true, then it's probably best to modify the other side if we don't really need those details there. We're going to assume that we've got some design liberties here and we're able to take a look at some of the direct modeling tools that we have, to get this thing a little bit closer to ready to produce. Let's rotate it around and let's get onto a front view, and I'm going to zoom out and I'm going to rotate it slightly. I'm going to be taking a look at press pull, and I'm going to select the top face of the design. I'm going to begin to pull this up. Then with the dimension dialog still highlighted, I'm going to select the top face of this bore. When I do that, I'm going to select, Okay, and notice how it left a small seam here. Now the reason it left a small seam, is because this is actually a metric designed part, and we're looking at it with the unit set to inch. There is going to be a number of decimal places that end up getting rounded, which means that we're a little bit off in terms of this geometry. Now it doesn't look that bad, but there is a face division, which means it might be harder for us to manufacture. What I'm going to do is, I'm actually going to start by selecting all of these inside bores, holding down the Shift key, and then I'm going to use modify and delete to bring them all up to the top face, then I'm going to select this entire face and use modify and delete. Notice that it's not able to do it. But if I select the smaller face and select modify delete, notice that it gets rid of that entire thing, but that's not really what we want to do because we need that geometry. We need to go in and we need to zoom way in until we find the small side face. It's hard to see, hard to grab. But what we want to do, is we want to figure out what that actually is. Now sometimes it can be easier if we go to a true orthographic view and we get rid of that perspective. It can be easier to zoom in and actually select that face. Also sometimes the material can make this a little bit more difficult, but I'm going to hold my mouse over there. I'm going to hold down the left mouse button, and I'm going to go until I select that small face. Another way that we could do this is actually use metric values, but sometimes you don't really have that option. With that selected, I'm going to hold down the Shift key and select this, and then I'll go back to modify and delete. That is able to get rid of that small difference between those two faces. Again, it's really just a product of the difference between metric and standard when we're rounding those units. I like to see perspective view with orthographic faces. I'm going to go back to that camera mode, but you can always carry on with just an orthographic view. Now that we've used press pull and we've used Delete to modify the backside, let's take a look at some of the other geometry that we may or may not need. Because this is a reflective part, there are going to be some views when you start to rotate this around that make it a bit easier. Now, if you want to simplify the color scheme, you can always go to Inspect and come color cycling, and if you don't like that color, you can always right-click on the component and cycle the color until you get to another color. These are going to be more of a flat, pastel style color, and you can always go back and turn that on or off at any point in time. That really helps when we're dealing with a lot of assemblies. At this point, we know that we've got a chamfer on all of these corners. While we can machine the chamfer with it actually in the model, we can do it without it in the model as well, and simply decide what we need there. When we're looking at this, the chamfer is really just there to ease the assembly of a bearing or a shaft, something that gets pressed in. The actual size of it may or may not be critical. What I'm going to do is I'm going to select all of these chamfers, and again holding down the Shift key, and then we can use delete on the keyboard or go to modify and delete to simply get rid of them. The main geometry we need, the bores and this hole that goes all the way through, those are all still there, but now what we have is a simplified version of this model that lets us go in and grab the edges that we need, grab a nice smooth face division if we need to face the backside before we flip it over. All that information is much cleaner than if we have a bunch of chamfers or a bunch of extra edges that we don't really need. At this point, let's make sure that we save the design. It's always a good idea to save often because we can always go back to previous versions. Now, that we've saved it, let's say that maybe we just wanted to change the size of the chamfer. Before it was a metric part and maybe it was just a little bit more difficult. Now we're going to go back and we're going to add our own chamfer, we're going to select all the edges that were chamfer before. We're simply going to manually put 0.05 as our Chamfer Edge. Notice, when we do that, we're getting a warning. It's telling us that it couldn't be created. It's telling us that it's basically, it's just too big. We can go smaller, 0.01. You see that's more in line with the size of the features that we're working with. Now that we've added that, let's go ahead and select "Okay", go back to our home view and let's save one more time before moving on to the next step.
