So anytime you're doing 3D, you can look at many videos as you want talking about the interface and tools, but really the best way to learn is to build something. So in this chapter, we're going to actually build a fire extinguisher. I've got a reference here. It is actually in the Images folder within the Chapter 02, exercise files. You can use any one, because we're not necessarily going to build this exactly over itself; we're actually just going to use this as a reference. So if you've got a fire extinguisher hanging on the wall of the office, you can grab a shot of that. Or if there's one sitting next to you, put it on your desk, and you can look at the nuances. Or just use this one right here.
Now, what we're going to use in this is some simple primitives to get started, of course a disc that we're going to pull up, and kind of pull in little bit with the Bevel tool and some other tools to create this nice shape at the top. But I'll show you how to do that and keep that curvature while also having a sharp corner. Later, I'm going to show you how to build the tube with some unique tools. We're going to use some other tools to work with different layers to actually build this band that goes around, holding the hose into place. But to get started, let's go ahead and just choose the Disc tool.
I'm going to hold the Alt, Option key and rotate around, so that I'm on my Y axis, just like that, and I can see with my workplane set to Y right there. Then I'm going to click and drag out a disc about yea big. But I'm going to go to my Radius in my Properties and I'm going to make sure that these are equal. So one is 545 millimeters and one is 570. It doesn't necessarily matter which one is which; just make sure they're both same. Position, make sure these are the same too.
You don't have to do it this way. You can very easily just go ahead and center it out after. So once that's done, we're going to click the Disc tool to turn it off, and center-select it all just to make sure that it is centered. So this is where our cylinder is going to begin for the fire extinguisher. Easy enough. Now, in order to bring this up, I can do it in a number of ways. We can do it as an extrude or as a bevel, and really the choice is yours. I'm going to go to Polygon mode, and then I'll select that polygon, because that's what I want to extend out from the base.
If I come down here to my Duplicate tools, you can see I've got Array, Radial, some other ones, Clone. Well, we don't really want to clone this because we don't want copies of it; we want to bring it up more. Well, what if I go down to Polygon? Here you can see I've got Bevel. I can choose that. When I click and activate the Bevel, a lot of people want to instantly click with the mouse and do this, and that's great, but you don't really have to do it that way. I use Bevel all the time just as a multiplication tool, just to multiply my selection.
So all I'm going to do is just drag that up. The only thing is that when I do this I don't have any segments in here. The segments would be good if I was going to bend this where I was going to create a different shade around the middle. But I can always go back and add that, so I'm not too worried about it. Now, we're not doing this exactly to scale. We've not measured the fire extinguisher. We're doing it by line of sight, simply just so that you can learn the tools, which is what the importance is here. So we've got a basic shape right there. So how do we handle the actual bevel of this? Well, let's press B again, which is Bevel, click to activate. And Inset is the red-- I'll click and drag on that--and Shift is the blue.
You can see right there that we get pretty much the basic shape right away, but it looks a little chunky, doesn't it? I can turn off the Bevel tool and then click to deselect that top polygon. What happens if I hit the Tab key? We get sort of a bullet shape. But really, it's very smooth, right? Well, the Tab key turns on subdivisions. This is something you're going to use all the time. In fact, when you create some little primitives, by default, that subdivision is already on. Okay, and what this is doing, you can see over here with the mesh selected, down here at the bottom, it says Subdivision Level of 2.
It's subdividing each one of those polygons to get a smoother shape. So all I need to worry about is adding more detail so that it sharpens it out. So we can work with edges. I'm going to double-click this edge and I'm going to Bevel. Press the B key and look what happens. We suddenly have beveled out that edge and added more geometry, allowing this to curve more properly. But I can add a Round Level to that bevel, perhaps two, and what that does is adds two segments right in there, just like that.
I'll hit the spacebar to turn off the tool, and then I'll click away from this to deselect. Now, you can see that we're starting to get that shape a little bit more like we want. But the top is not quite right. So I'll jump back to Polygon mode. Choose this. I'm going to bevel again. Just click, and notice that as soon as we do that, because of the subdivision modes, we have a much cleaner object. I can very simply just scale this in a little bit and pull this up.
Then to make another bevel, hold the Shift key and click one more time. Now we've got a very nice shape to work with. So I'll click the Bevel tool to turn it off, click away from it to deselect that polygon, and now we've got that relatively nice shape. It's a little too straight here. So how would you then go about adjusting this? Well, I'm going to go back to Edge mode. Because I don't need to work with the polygons now-- I need to work with the edges-- I'm going to double-click this edge, and under the Geometry menu, I'm going to choose Slide.
I'm going to move up my Properties here so you can see what's happening, and make sure that all these defaults are on and Duplicate is off, because what Slide will do is let you drag this edge on that contour. But a feature in modo 501 called Preserve Curvature should be on. What that will do is allow you to keep any kind of curvature in that shape. Now we've got a very nice even curve across the top. So spacebar to turn off the tool and then click a blank area to deselect.
Now the last thing we need to do on this base, if we go down to the bottom and hold the Alt, Option key to rotate around, you'll notice that because polygons in modo are one sided, we've got this open bottom. The reason it's open is because, remember, we had one polygon, and we just went up with it. So there's really nothing there. So again, in Edge mode, double-click, just move your mouse-- I'll get close so you can see this-- move your mouse just right over that edge. And I'm clicking and holding, by the way, on the top right again. Click and hold to move like that.
So when you see your mouse highlight over that edge at the bottom, double-click it, and then you can press the P key to create a polygon-- another keyboard shortcut you'll use often. That looks terrible, right? That's okay, because what's happening is that you've just attached all these. You just created a polygon from those selected edges. You just need to add a little more detail. So we'll jump back to Polygons and because we just created that, it's already selected for us. Then we'll choose Bevel and just click it like that.
That adds a little more geometry. Then I'm going to Shift+Click to activate Bevel again, and this time I'll just inset it a bit. I'll turn off Bevel, click to deselect. And that extra bevel there, see how it just rounded that corner for us very nicely? That's all you really need. You can always go back and add more edges. I'll press the A key to fit, and the last thing I need to do is press the M key, Polygon Set Material. And we'll call this Fire_Ex_Base, and then I'll set a color for it.
I'll click the color wheel and choose Red and click OK. Now, you don't have to set a color right here; you can always do that later. The biggest thing is that you're telling these polygons they have a specific name named Fire Extinguisher, or whatever you'd like to call it. I'll click OK. Then we'll save. So File > Save. Then I'm going to make sure this goes to our Desktop > Exercise Files > CH02. I'll call this Fire_Ex_v1.
That way you can load this up and continue from here if you like. So with a very basic primitive of just a flat disc, within a matter of minutes you can actually create a realistic model. But of course, we've got a lot more to do with this to create the hose and some of the metal clamps. So in the next few videos, you'll see exactly how to do that with some of the additional modeling tools.
