WEBVTT 1 00:00:00.000 --> 00:00:04.000 Welcome to Duplication and Merging! 2 00:00:04.000 --> 00:00:08.000 So in this video we are going to learn about duplication, 3 00:00:08.000 --> 00:00:12.000 because there are two types of it, and create one mesh 4 00:00:12.000 --> 00:00:16.000 from multiple objects. So let's hop straight 5 00:00:16.000 --> 00:00:17.200 over into Blender! 6 00:00:17.833 --> 00:00:21.833 So here we have our wedge pointing upwards, that we were using before. 7 00:00:21.833 --> 00:00:25.833 So we want to make a duplicate 8 00:00:25.833 --> 00:00:29.833 of that wedge. So if we go down to Object 9 00:00:29.833 --> 00:00:33.833 and about midway up there are two Duplicate 10 00:00:33.833 --> 00:00:37.833 Options, there's Duplicate Objects and Duplicate Linked. 11 00:00:37.833 --> 00:00:41.833 They are almost the same but they 12 00:00:41.833 --> 00:00:45.833 have some radical differences. So we're going to, first of all, 13 00:00:45.833 --> 00:00:49.833 Duplicate Linked. Now nothing happens immediately 14 00:00:49.833 --> 00:00:53.833 but if we move the mouse we can see there's another wedge 15 00:00:53.833 --> 00:00:57.833 right next to it. Now these two are linked and we can 16 00:00:57.833 --> 00:01:01.833 see, in the Outliner, it's produced another wedge with Wedge 17 00:01:01.833 --> 00:01:05.833 001. I'm just going to name that 18 00:01:05.833 --> 00:01:09.833 something more appropriate, straight away, and call that the copy 19 00:01:09.833 --> 00:01:13.833 just so I know which one's what. So because they're linked, 20 00:01:13.833 --> 00:01:17.833 they should do similar things to one another. 21 00:01:17.833 --> 00:01:21.833 However, when you're in Object Mode, if you just say change 22 00:01:21.833 --> 00:01:25.833 the scale of something it doesn't effect the other object. And 23 00:01:25.833 --> 00:01:29.833 you may be wondering well they're linked, well why isn't this one 24 00:01:29.833 --> 00:01:33.833 resizing this one, because they are linked and that's the whole point 25 00:01:33.833 --> 00:01:37.833 of linking them in the first place. Well if we go to Edit 26 00:01:37.833 --> 00:01:41.833 Mode and we start playing about with our model, let's say moving that edge 27 00:01:41.833 --> 00:01:45.833 down, you can see then it does effect the other side! 28 00:01:45.833 --> 00:01:49.833 And similarly, if we hop over to this wedge, 29 00:01:49.833 --> 00:01:53.833 our original one, and go into Edit Mode, we can 30 00:01:53.833 --> 00:01:57.833 see that that also effects it. So that's really cool! See 31 00:01:57.833 --> 00:02:01.833 you can alter the actual structure of a mesh, 32 00:02:01.833 --> 00:02:05.833 however you can scale things completely independently of one another. 33 00:02:05.833 --> 00:02:09.833 So in Object Mode these two are actually an identical mesh, however, 34 00:02:09.833 --> 00:02:13.833 this one has a different Z scale to it, so it's 35 00:02:13.833 --> 00:02:17.833 slightly taller. In fact, in this case, oh in this case because 36 00:02:17.833 --> 00:02:21.833 there it's twice as wide along the bottom. So it's a great 37 00:02:21.833 --> 00:02:25.833 way of using a base mesh and actually 38 00:02:25.833 --> 00:02:29.833 using it to create more things, down the line, but also vary them 39 00:02:29.833 --> 00:02:33.833 so they're not all the same. Now if we switch 40 00:02:33.833 --> 00:02:37.833 over to Duplicate Objects and I 41 00:02:37.833 --> 00:02:41.833 place this one over here, it is completely independent. 42 00:02:41.833 --> 00:02:45.833 It's essentially a complete copy of the wedge. 43 00:02:45.833 --> 00:02:49.833 In fact, it is a copy of this one, because that's what we've copied 44 00:02:49.833 --> 00:02:53.833 in every form and face. So if we went into 45 00:02:53.833 --> 00:02:57.833 Edit Mode on that and moved it about, it is completely independent 46 00:02:57.833 --> 00:03:01.833 of these two. Right, so I 47 00:03:01.833 --> 00:03:05.833 want to get rid of that redundant wedge, and I can actually delete it straight 48 00:03:05.833 --> 00:03:09.833 here. You see I see it's Wedge Copy 001. I can right-click 49 00:03:09.833 --> 00:03:13.833 there and just Delete. Alternatively, I could go down to 50 00:03:13.833 --> 00:03:17.833 switch it to Object Mode and go to Object and 51 00:03:17.833 --> 00:03:21.833 Delete is there, or press the X key and confirm, but I'm just going to do it in the 52 00:03:21.833 --> 00:03:25.833 Outliner. So we have these two wedges 53 00:03:25.833 --> 00:03:29.833 here and it's produced two meshes, as we can see, but 54 00:03:29.833 --> 00:03:33.833 we may want that, eventually, to become one object. 55 00:03:33.833 --> 00:03:37.833 So how do we do that? Well let's open up our Tool 56 00:03:37.833 --> 00:03:41.833 Shelf again. Now you can leave these things open, by the way. I 57 00:03:41.833 --> 00:03:45.833 just put them away when I'm not using them, because I'm running a lower 58 00:03:45.833 --> 00:03:49.833 resolution than you might be. And we see an option here 59 00:03:49.833 --> 00:03:53.833 to Join. If we click Join, well it 60 00:03:53.833 --> 00:03:57.833 doesn't do anything because we've not got two or more meshes selected. 61 00:03:57.833 --> 00:04:01.833 So if we hold down Shift and select the other mesh, we see 62 00:04:01.833 --> 00:04:05.833 that one is active, which is orange, and this one has gone a kind of red to 63 00:04:05.833 --> 00:04:09.833 mean it's included in the selection. If we now go to Join, 64 00:04:09.833 --> 00:04:13.833 it's actually put them under one mesh. Now 65 00:04:13.833 --> 00:04:17.833 incidentally, that's also broken the link that they had before. 66 00:04:17.833 --> 00:04:21.833 So we've got both things selected there, however, if I just select 67 00:04:21.833 --> 00:04:25.833 this one it now moves independently. So they're no longer 68 00:04:25.833 --> 00:04:29.833 a duplicate linked object, the moment you join them back 69 00:04:29.833 --> 00:04:33.833 together, so it's worth bearing that in mind. OK, 70 00:04:33.833 --> 00:04:37.633 I feel a challenge coming on! Are you guys ready?! 71 00:04:37.633 --> 00:04:39.766 We're going to create a 72 00:04:39.766 --> 00:04:43.766 periscope! So I would like you to create a periscope, 73 00:04:43.766 --> 00:04:47.766 existing of 2 wedges with a cube 74 00:04:47.766 --> 00:04:51.766 in the middle. And just to make it a bit more challenging, I would like 75 00:04:51.766 --> 00:04:55.766 the periscope's base to be at (0, 0, 0). 76 00:04:57.366 --> 00:05:01.366 And just for reference, this is the type of shape 77 00:05:01.366 --> 00:05:05.366 we are looking for, a very basic periscope, 78 00:05:05.366 --> 00:05:09.266 or I suppose, looking at it, a 3D parallelogram. 79 00:05:09.266 --> 00:05:12.666 So pause the video now, go off, and give that a 80 00:05:12.666 --> 00:05:16.666 go! OK 81 00:05:16.666 --> 00:05:20.666 welcome back! Let's hop into Blender and see if we can solve 82 00:05:20.666 --> 00:05:24.666 our periscope issue! So I've been playing lots 83 00:05:24.666 --> 00:05:28.666 with these wedges. I've been moving them up and down, moving them left and right, 84 00:05:28.666 --> 00:05:32.666 and so I've got myself in a bit of a pickle. And if you ever 85 00:05:32.666 --> 00:05:36.666 do this, you may want to consider remaking 86 00:05:36.666 --> 00:05:40.666 your wedge, because it can sometimes be quicker 87 00:05:40.666 --> 00:05:44.666 to just start from scratch, rather than trying to repair these wedges 88 00:05:44.666 --> 00:05:48.666 so they look like the periscope. 89 00:05:48.666 --> 00:05:52.666 They're a bit hard to work with at the moment. So I'm just going to 90 00:05:52.666 --> 00:05:56.666 Delete my wedge completely. I'm then going to 91 00:05:56.666 --> 00:06:00.666 create a cube, I'm going to zoom 92 00:06:00.666 --> 00:06:04.666 in, and let's see what we can do here. I'm going to go into Edit Mode, 93 00:06:04.666 --> 00:06:08.666 and with Vertex Select, I'm going to 94 00:06:08.666 --> 00:06:12.666 remove that vertex there and this one here. You may remember this from the creation 95 00:06:12.666 --> 00:06:16.666 of our wedge. And I'm just going to Delete the 96 00:06:16.666 --> 00:06:20.666 Vertices, and then, I'm just going to Join these up, as we've 97 00:06:20.666 --> 00:06:24.666 done before, and that will 98 00:06:24.666 --> 00:06:28.666 create our first wedge for our periscope. 99 00:06:31.500 --> 00:06:34.800 So the next thing we need to do is... 100 00:06:34.800 --> 00:06:38.800 Well a periscope is that plus another one, so I 101 00:06:38.800 --> 00:06:42.800 am going to go to Mesh, I'm going to... Ooh, let's switch to 102 00:06:42.800 --> 00:06:46.800 Object Mode first. I'm going to go to Object and then go to Duplicate. 103 00:06:46.800 --> 00:06:50.800 In this case, I am going to just duplicate it, I don't need them to be 104 00:06:50.800 --> 00:06:54.800 linked. And we've got our other one here, so I'm just going to click that, 105 00:06:54.800 --> 00:06:58.800 and I'm going to place that still at 0, 0 on the X, 106 00:06:58.800 --> 00:07:02.800 Y. But I'm going to basically 107 00:07:02.800 --> 00:07:06.800 lift it up, let's say, by 4 for the moment so it's just above 108 00:07:06.800 --> 00:07:10.800 the other one. OK, 109 00:07:10.800 --> 00:07:14.800 it looks like our wedge here isn't at 0, 0, because that 110 00:07:14.800 --> 00:07:18.800 was the position of the 3D cursor, when we started. So now these two 111 00:07:18.800 --> 00:07:22.800 should be in line with one another. Now this bottom one, 112 00:07:22.800 --> 00:07:26.800 I want it to be the other way around, so I'm going to rotate it. Let's see, 113 00:07:26.800 --> 00:07:30.800 skewer through the X axis there. I'm going to rotate that 114 00:07:30.800 --> 00:07:34.800 by 180, so it becomes upside down. That's great! 115 00:07:34.800 --> 00:07:38.800 In fact, that's looking good already, however that's not on the 116 00:07:38.800 --> 00:07:42.800 base, at the moment, however, I'll deal with that, in a moment, once I've joined all 117 00:07:42.800 --> 00:07:46.800 of these together. The final thing is to put a cube into the middle of 118 00:07:46.800 --> 00:07:50.800 this mesh, and again, it's produced the cube at the 119 00:07:50.800 --> 00:07:54.800 3D cursor, rather than anywhere else. So I 120 00:07:54.800 --> 00:07:58.800 want the X and Y to both be 0, and 121 00:07:58.800 --> 00:08:02.800 here this just needs to be 1. Nope! Let's try 2! 122 00:08:02.800 --> 00:08:06.800 Perfect! So there we have our base periscope shape. 123 00:08:06.800 --> 00:08:10.800 Now what we want to do here is just lift it up, so it's 124 00:08:10.800 --> 00:08:14.800 base is where the Z basically equals 0. 125 00:08:14.800 --> 00:08:18.800 So the first thing I'm going to do is highlight all of my 126 00:08:18.800 --> 00:08:22.800 objects, and I'm going 127 00:08:22.800 --> 00:08:26.800 to go to Tools, on the side here, and go to 128 00:08:26.800 --> 00:08:30.800 Join. So there we go, we've got one shape now, one mesh, 129 00:08:30.800 --> 00:08:34.800 that makes up our periscope and I just need to lift it up. 130 00:08:34.800 --> 00:08:38.800 And as we can see, the Origin of this shape has been set 131 00:08:38.800 --> 00:08:42.800 to the bottom. So, in this case, I think we just need to 132 00:08:42.800 --> 00:08:46.800 lift it up by 1. So if we lift it up by 1, bang! That's 133 00:08:46.800 --> 00:08:50.800 bang on the surface complete! So there we go, 134 00:08:50.800 --> 00:08:54.800 there's our periscope! How did you guys get on?! Please 135 00:08:54.800 --> 00:08:56.700 remember to post your 136 00:08:56.933 --> 00:09:00.933 periscope in the discussions so we can see how you got on!
