2.2 Extrude the 3D Wheel
Hi everyone, and welcome back to the oddly satisfying pendulum animation course. In this lesson, we will learn how to use splines to create our 3D wheel object. So now that we have the shape of our wheel successfully illustrated using our splines, the next thing we need to do is to convert the spline mask into something editable. So make sure that the spline mask is selected, right-click, and select Current State to Object, which will allow us to extrude the splines. This will also create a duplicate spline object separate from our original that we can now use and edit. Now the duplicate is useful just in case we find out that the shape isn't quite what we want, and that we need to go back into our spline mask make some adjustments to the circle and the cloner, such as position and size. If you want to keep the original, all we have to do is hide this by clicking on the little small gray circular buttons here until they turn red, so they're hidden. Or if you're confident enough to go ahead, we can just delete the original by selecting it and hitting the Delete button on the keyboard like so. Next we want to make sure that the access of our spline mask is centered. So go over to Mesh, making sure firstly, that the spline mask is selected. Then go to Axis Center and select the Axis Center. Everything here leave it to the default, making sure that all this is at 0%, and select Execute like so. Next we want to extrude our 3D object out of the splines. So, let's go ahead and move into the perspective view. So, click the middle mouse button to bring all four of our views out, like so. And then, let's click the middle mouse button whilst hovering over perspective to maximize our perspective view. And this will give us a better look at our 3D object. Now we want to extrude this. So to do this, we want to move to the top button menu here, go to Subdivision Surface, click and hold down the button to reveal this menu here aand select Extrusion. Cool, now we have this extrude here in our list, we have to move our spline mask, click and drag it into the extrude like so. And you'll see straight away that we have a 3D object with the pendulum-shaped holes, excellent. Now we can start to adjust the object by going over to the Attributes panel here and playing about with some of the settings. So make sure that the Extrude is selected, not the Spine Mask, so move over to the Extrude and let's start with the Caps tab here. Now we want to go ahead and select the Fillet Cap from the drop-down menu at the start. So select Fillet Cap here and you'll see straightaway that we've got these nice beveled edges for our wheel. And we can do the same for the other side, so over where it says End, select Filler Cap here, and now we've got two nice beveled edges for our wheel, which will give us a much nicer and believable edge to our shape here. Now we can also go ahead and select how thin or thick we want our edges to be. So let's bring the radius to about, let's say one centimeter and the same to the other side. So bring the radius down to one centimeter like so, and now we want to adjust the width of the wheel. So let's go back to the Object tab, and over here, we can change the movement value from 20 centimeters to something like 40. And you'll see that the width of our wheel is a little bit thicker, so we can adjust the value of the movement like so. So let's leave it at 40 centimeters and let's go ahead and look at the edges of our wheel. And you'll notice that all the edges have been beveled apart from the tips here. So we've got some sharp corners here and inside the corners here where our pendulum holes are, there are some sharp corners here as well. Now these will have to be manually adjusted. So let's go ahead and convert the extrude object by selecting it, right-click on our extrude object here, and let's go ahead and select Current State Object. Now, before we do this, we want to make sure that our caps have been set to create a single object like so. Now the reason why we wanna do this, is if we create a object from here, this will create two separate objects. So this will create a side here, which you can see if I go ahead and move this like so. So we've got one side here and we've got another side here, and when we really just want one single object. So let's go ahead and delete this, select our Extrude Object, and select Create Single Objects like so, .and we wanted to delete the font tag here too. So let's go ahead and delete that. And now from here, let's go ahead and right-click and select Current State Objects. And now you'll see we have one singular shape, like so, which is exactly what we want, excellent. So from here let's go ahead and delete our extruded object, our previous one. And now we want to select the Edge Selection tool, select our Extrude Object here. And we want to manually select the edges by using the Live Selection tool. So click and hold down here to select the Live Selection tool and we want to select the edges like so. So click that and in order to select several edges, we want to press and hold t the Shift key on the keyboard, and click. And there we have it, we've got two selected edges. So let's just go round the wheel and select the sharp edges like so and let's go down to this one. And you'll notice, as I hover over the edges, the edges highlight in white. So we want to make sure that we only hover over the edge that we want to select. And then press and hold the Shift key on the keyboard whilst clicking to select multiple edges, just going around the wheel like so. And we can also make the edge selector, the live selection tool bigger or larger by pressing and holding the square bracket keys on the keyboard. So let's go ahead and make this selection circle a little bit smaller so that we can be a little bit more accurate with our selections. And finally, the top here, like so. And now let's move down to our pendulum holes, so clicking on the sharp edges. Just moving around the wheel and selecting these edges here, Making sure that we are using a correct angle just so that we do not accidentally select multiple edges. And let's go back into our final hole here. And you'll see that I've accidentally selected an edge here. So in order to deselect that, you want to press and hold the Ctrl key on the keyboard and click it to deselect like so. So let's see that again. So if I accidentally clicked on these three edges here, just press and hold the Ctrl key on the keyboard, highlight the edges that you want to deselect and then click them, cool. So now going over our shape one more time, we've got all of our edges selected. The next thing we want to do is we want to right-click on the edge, select the Bevel tool. And now we can go ahead and click and hold and drag the Bevel tool to bevel our edges, like so. So let's zoom in here just so we can get a closer look at exactly what we're doing, and we just wanna have a small little bevel like so. We can also enter a value here, so let's enter the same values what we had before. So, one centimeter and we can also create some extra subdivisions. So we can create an extra one or two subdivisions to make our bevel a little bit curvier. So let's go ahead and enter a value 2, or let's see, let's have 1.5 see what that looks like, cool and that's looking nice and curvy. I'm just checking the pendulum hole. And once you're happy with the selection, just go back to the model mode by clicking on the model button here. Click back on the live selection tool and there we have it. A nice beveled wheel model with our pendulum holes. Now, you'll notice as we move around our 3D wheel object, we've got these jagged lines which don't look particularly pretty as we look around our wheel. Now, in order to remove these, all we have to do is select our Fon tag at the top here. And let's move the angle down to about 40% and you'll see the lines have magically disappeared. So you'll see before and after, so this leaves behind a nice smooth wheel object for our design, excellent. So that is it for this lesson, in the next lesson, we'll learn how to animate the wheel, see you all there.
