WEBVTT 1 00:00:00.133 --> 00:00:04.133 Welcome to Spin in Blender or Rotational 2 00:00:04.133 --> 00:00:08.133 Extrusion! So in this video we're going to 3 00:00:08.133 --> 00:00:12.133 convert the curve that we've made into a mesh object. We're going 4 00:00:12.133 --> 00:00:16.133 to learn that a curve is still infinitely editable, and 5 00:00:16.133 --> 00:00:20.133 using the Spin Tool we will make our pin. So let's 6 00:00:20.133 --> 00:00:22.533 hop over into Blender! 7 00:00:22.533 --> 00:00:26.533 Welcome back into Blender! So we have our curve 8 00:00:26.533 --> 00:00:30.533 all there and sorted. Now I'm quite happy to get rid of our 9 00:00:30.533 --> 00:00:34.533 cube that we made earlier, as our reference cube, as we're not going to 10 00:00:34.533 --> 00:00:38.533 need it anymore, in this case. So I'm going to select that and just get rid of it 11 00:00:38.533 --> 00:00:42.533 completely. OK, we've got our Bezier Curve 12 00:00:42.533 --> 00:00:46.533 here, which is great, and I'm going to go over to the Outliner here 13 00:00:46.533 --> 00:00:50.533 and just name our Bezier Curve something more descriptive, like 14 00:00:50.533 --> 00:00:54.533 Pin Outline. It's very important you keep this naming 15 00:00:54.700 --> 00:00:57.266 throughout your production, because when you're 16 00:00:57.266 --> 00:01:01.266 models get more complicated, you're not going to be able to find anything. Right! 17 00:01:01.266 --> 00:01:05.266 So we need to convert this into a mesh object, 18 00:01:05.266 --> 00:01:09.266 and you can do that by going down to Object, 19 00:01:09.266 --> 00:01:12.366 and, in my case, I'm going to have to scroll up a little. 20 00:01:12.366 --> 00:01:15.066 There we go! Convert to... 21 00:01:15.066 --> 00:01:19.066 And we can see the shortcut key there is Alt and C, and we want to 22 00:01:19.066 --> 00:01:23.066 make a Mesh from a Curve, so we're going to 23 00:01:23.066 --> 00:01:27.066 select that. And we can see, over in the Outliner, that it's created 24 00:01:27.066 --> 00:01:31.066 a mesh object, that icon there has changed. Now in 25 00:01:31.066 --> 00:01:35.066 case you wanted to keep the original data, the curve, you can 26 00:01:35.066 --> 00:01:39.066 opt down here in the operator panel to 27 00:01:39.066 --> 00:01:43.066 keep the original, and then, we can see we get Pin Outline 28 00:01:43.066 --> 00:01:47.066 and Pin Outline 001 and one is a mesh object. 29 00:01:47.066 --> 00:01:51.066 Now I'm going to go straight into that, because I know that this mesh object is about 30 00:01:51.066 --> 00:01:55.066 to just become our pin. So there we go, 31 00:01:55.066 --> 00:01:59.066 we've converted that curve straight into 32 00:01:59.066 --> 00:02:03.066 a mesh. Now we've left the curve there, the curve is infinitely 33 00:02:03.066 --> 00:02:07.066 editable, it's a mathematical calculation, which is great! 34 00:02:07.066 --> 00:02:11.066 Once we've created a mesh 35 00:02:11.066 --> 00:02:15.066 out of it, it essentially becomes solidified, as we mentioned, and if 36 00:02:15.066 --> 00:02:18.733 I hide the pin outline, by clicking on the little 37 00:02:18.733 --> 00:02:21.900 eye icon there, we can see 38 00:02:21.900 --> 00:02:25.900 that our pin itself is now made up of, if we hop in to 39 00:02:25.900 --> 00:02:29.900 select it first hop into Edit Mode, it's made up of a 40 00:02:29.900 --> 00:02:33.900 series of vertices. If we highlight the entire lot, 41 00:02:33.900 --> 00:02:37.900 because we're going to need that in a moment, we can then perform some 42 00:02:37.900 --> 00:02:41.900 operations on it. So for instance, if that was just something we want 43 00:02:41.900 --> 00:02:45.900 to extrude out, we could do that straight away, which is great! But we want to 44 00:02:45.900 --> 00:02:49.900 rotationally extrude, how do we do that? Well 45 00:02:49.900 --> 00:02:53.900 once we're in Edit Mode and we've selected all of the geometry 46 00:02:53.900 --> 00:02:57.900 we want to manipulate, in this case it's everything, we can go 47 00:02:57.900 --> 00:03:01.900 Tools on the Tool Shelf, scroll down a little if you can't see it already, 48 00:03:01.900 --> 00:03:05.900 and click straight on Spin, and we can see the shortcut there is 49 00:03:05.900 --> 00:03:09.900 Alt and R. So by pressing Alt and R, we 50 00:03:09.900 --> 00:03:13.900 perform a Spin. Now, that doesn't look anything 51 00:03:13.900 --> 00:03:17.900 like our pin! So 52 00:03:17.900 --> 00:03:21.900 why? Well we're going to have to look down in the Operator Panel, so I'm just going to 53 00:03:21.900 --> 00:03:25.900 make this a bit bigger, because there are a few more options here, and let's 54 00:03:25.900 --> 00:03:28.866 go down them one by one. Steps is the number of 55 00:03:28.866 --> 00:03:32.666 steps there are. It increases, the more steps you have the more detailed 56 00:03:32.666 --> 00:03:36.666 it becomes. Now, it's quite a cool shape but it's not a pin! 57 00:03:36.666 --> 00:03:40.666 Angle, well that is the angle at which it goes around. In fact, 58 00:03:40.666 --> 00:03:44.666 it looks like some sort of funky wheel or break disc or plate, at the moment, which is 59 00:03:44.666 --> 00:03:48.666 great, and obviously, you rotate all the way around until you meet 360. That's fine! 60 00:03:48.666 --> 00:03:52.666 The center, well the center moves 61 00:03:52.666 --> 00:03:56.666 each individual part of the rotation, and we actually 62 00:03:56.666 --> 00:04:00.666 just want everything here at 0. So if it's not at 0, do set it 63 00:04:00.666 --> 00:04:01.866 at 0 now. 64 00:04:01.866 --> 00:04:04.033 Alright, now everything's at 65 00:04:04.033 --> 00:04:08.033 0! It's still not quite right, we need to play with these axes down 66 00:04:08.033 --> 00:04:12.033 here, and we're not rotating it in any way on the X and Y, 67 00:04:12.033 --> 00:04:16.033 so we can definitely delete that and we have a pin 68 00:04:16.033 --> 00:04:20.033 shape. Excellent! It's only 69 00:04:20.033 --> 00:04:24.033 42 degrees of a pin but none the less that's always good! 70 00:04:24.033 --> 00:04:28.033 Right, 160 degrees! Sorry, I was reading the wrong thing there! 71 00:04:28.033 --> 00:04:31.566 Steps 42, Angle 160! That's great! 72 00:04:31.566 --> 00:04:35.566 OK, it's challenge time! I'd like you guys to finish the pin! 73 00:04:35.566 --> 00:04:39.566 So go ahead and finish off the pin and consider the 74 00:04:39.566 --> 00:04:43.566 following please. I'd like you to remove any doubles that are created 75 00:04:43.566 --> 00:04:47.566 during the process. Get the normals the right way around, because 76 00:04:47.566 --> 00:04:51.566 there's a chance that they will be the wrong way around. So there's a little hint 77 00:04:51.566 --> 00:04:55.566 there for you! And finally, set the base of the pin on the XY Plane, 78 00:04:55.566 --> 00:04:59.566 just to finish it off, and that's where Z=0. So go ahead, 79 00:04:59.566 --> 00:05:03.566 pause the video now, and give that a go! 80 00:05:03.566 --> 00:05:07.566 OK welcome back! Let's hop back over into Blender! 81 00:05:08.666 --> 00:05:12.666 So over in Blender... Well straight away I know I want 82 00:05:12.666 --> 00:05:16.666 360 degrees, so I'm just going to wack that in straight away, 83 00:05:16.666 --> 00:05:20.666 and I'm just going to have a look at my pin and just adjust this Z value 84 00:05:20.666 --> 00:05:24.666 to... You see, that's normals that are the wrong way around, and that's 85 00:05:24.666 --> 00:05:28.666 normals that are the right way around! So it's quite a distinctive color change, and 86 00:05:28.666 --> 00:05:32.666 eye will tune into that very quickly. So now we've got that the right way 87 00:05:32.666 --> 00:05:36.666 around. I do want to change our Steps, I think that's a few too many steps, actually. 88 00:05:36.666 --> 00:05:40.666 I think that's over the top, so I'm just going to lower that down. 89 00:05:40.666 --> 00:05:44.666 Now 16's a bit too low, 32 90 00:05:44.666 --> 00:05:48.666 a bit high. I want to go for, in the middle of that, 24! 91 00:05:48.666 --> 00:05:52.666 Yeah, there we go! I'm happy with that! Now, one thing to bear in 92 00:05:52.666 --> 00:05:56.666 mind is, because we've gone around at a whole 360 degrees 93 00:05:56.666 --> 00:06:00.666 there will be a series of duplicate vertices actually, along 94 00:06:00.666 --> 00:06:04.666 this seem that we can see, where we started from, because it also put a 95 00:06:04.666 --> 00:06:08.666 layer down when we finished. So we need to just select our 96 00:06:08.666 --> 00:06:12.666 entire model, ensuring there's no further doubles, 97 00:06:12.666 --> 00:06:16.666 and on the Tool Shelf I'm just going to Remove Doubles, as we've done before. And we can see I've actually 98 00:06:16.666 --> 00:06:20.666 removed 120 vertices, at that point, so there was a 99 00:06:20.666 --> 00:06:24.666 bit of mess in our model there but now it's all gone! Excellent! 100 00:06:25.033 --> 00:06:28.366 So the one thing left to do then, in our model, 101 00:06:28.366 --> 00:06:32.366 is just lift it up so it's actually on the X Y plane. So I'm simply going 102 00:06:32.366 --> 00:06:36.366 to grab it, I'm going to lock it to the Z axis so it's still in the middle, 103 00:06:36.366 --> 00:06:40.366 and, if I believe, it's 1.9, and that should make us 104 00:06:40.366 --> 00:06:44.366 all the way up there. I'm just going to change the view to the Front 105 00:06:44.366 --> 00:06:48.366 and there we go! Yeah, I'm happy, that looks like it's bang on the bottom and it is! And 106 00:06:48.366 --> 00:06:51.100 there we go! There's our pin! 107 00:06:51.100 --> 00:06:53.966 Remember to share this in the discussions, so I can 108 00:06:53.966 --> 00:06:57.966 see what you guys have been up to, and I shall see you in the next lecture!
