WEBVTT 1 00:00:00.000 --> 00:00:04.000 Hi guys, welcome to The Snapping Tool! In this 2 00:00:04.000 --> 00:00:08.000 video we're going to learn another way for you guys to constrain your 3 00:00:08.000 --> 00:00:12.000 movement. We're going to be using the Snapping Tool to do that. 4 00:00:12.000 --> 00:00:15.466 I'll show you how to snap objects into place and how to tell it 5 00:00:15.466 --> 00:00:18.700 what to snap to, and controlling whether 6 00:00:18.700 --> 00:00:22.700 or not you merge vertices, when you put the two things on 7 00:00:22.700 --> 00:00:26.333 top of one another. So let's hop over into Blender! 8 00:00:28.333 --> 00:00:32.333 So I don't want to start adding random things to our 9 00:00:32.333 --> 00:00:36.333 pyramid, so let's open up a new Blender file. 10 00:00:36.333 --> 00:00:40.333 So I'm going to go and save my pyramid first. As always, 11 00:00:40.333 --> 00:00:44.333 saving is important. I'm going to go to New and load up a new 12 00:00:44.333 --> 00:00:48.333 Blender file. So we have one cube here. By default, 13 00:00:48.333 --> 00:00:52.333 snapping is turned off, and you can find the Snapping Tool 14 00:00:52.333 --> 00:00:56.333 along the 3D Editor Header, towards the right-hand side. 15 00:00:56.333 --> 00:01:00.333 It looks like a picture of a magnet. When it's turned on, it 16 00:01:00.333 --> 00:01:04.333 even looks more like a magnet and that's exactly what it is. And we can see the 17 00:01:04.333 --> 00:01:08.333 shortcut is Shift and Tab. Now this is one of those 18 00:01:08.333 --> 00:01:12.333 shortcuts, which is incredibly useful because when we start moving 19 00:01:12.333 --> 00:01:16.333 our object, this 3D Editor header 20 00:01:16.333 --> 00:01:20.333 disappears. So let's demonstrate that now! If I go 21 00:01:20.333 --> 00:01:24.333 and move my cube, you can see snapping is actually turned on, and it's actually snapping 22 00:01:24.333 --> 00:01:28.333 into the grid in front of us, so it's moving one Blender unit at a time, 23 00:01:28.333 --> 00:01:32.333 in a random direction. If we constrain it to Z it will be 24 00:01:32.333 --> 00:01:36.333 locked in the Z axis. So by knowing 25 00:01:36.333 --> 00:01:40.333 Shift and Tab, we can turn that on and off to our 26 00:01:40.333 --> 00:01:44.333 heart's content, even if we've started the movement without 27 00:01:44.333 --> 00:01:48.333 it being turned on. Perfect! 28 00:01:48.333 --> 00:01:52.333 So the other options, what else can we snap to? Well we're going to need something 29 00:01:52.333 --> 00:01:56.333 else to snap this cube to, and we can pick Faces, 30 00:01:56.333 --> 00:02:00.333 Edge, or Vertex. So let's generate another cube 31 00:02:00.333 --> 00:02:04.333 in our scene. 32 00:02:04.333 --> 00:02:08.333 And let's lift that up, and we can see snapping's turned on. 33 00:02:08.333 --> 00:02:12.333 That's kind of cheating because, of course, I can align that absolutely perfect. 34 00:02:12.333 --> 00:02:16.333 There we go, perfectly aligned! But we want to know how to use these 35 00:02:16.333 --> 00:02:20.333 other options here, so let's make it not so perfect and dump it 36 00:02:20.333 --> 00:02:24.333 some random place over there. Because once you've done that and you start moving it 37 00:02:24.333 --> 00:02:28.333 with the snapping turned on, they won't line up again, because it's 38 00:02:28.333 --> 00:02:32.333 one Blender unit relative to where its new position was. 39 00:02:32.333 --> 00:02:36.333 So if we pick a face and we can then 40 00:02:36.333 --> 00:02:40.333 move this model... I'm just using moving as an example, but it can 41 00:02:40.333 --> 00:02:44.333 be any one of the rotations, scaling, etc. 42 00:02:44.333 --> 00:02:48.333 If I move the cursor over this face 43 00:02:48.333 --> 00:02:52.333 and click, that cube is now against that face 44 00:02:52.333 --> 00:02:56.333 perfectly! If I want it to be a bit more precise I could go to Edge, 45 00:02:56.333 --> 00:03:00.333 and when I go to move it then... Ah, do bear in 46 00:03:00.333 --> 00:03:04.333 mind, the position of your cursor. It's going to be very snappy and jerk all over the place, 47 00:03:04.333 --> 00:03:08.333 if the cursor's over the top of your object when you start the move. But if the 48 00:03:08.333 --> 00:03:12.333 cursor's away from your object, then you can place it over and you can see it 49 00:03:12.333 --> 00:03:16.333 ping snaps into place. And now those two cubes 50 00:03:16.333 --> 00:03:20.333 are basically, they're face planted together which is great, 51 00:03:20.333 --> 00:03:24.333 and these edges are on top of one another. So I could grab it and 52 00:03:24.333 --> 00:03:28.333 lower it down to this edge, or I could be even more precise in going, I want a 53 00:03:28.333 --> 00:03:32.333 Vertex. I want to snap to the vertex, and 54 00:03:32.333 --> 00:03:36.333 down in this bottom corner here. So again, we can move it and point it at that 55 00:03:36.333 --> 00:03:40.033 and click, and now these two cubes are exactly aligned. 56 00:03:40.033 --> 00:03:42.366 The final thing to mention here is, if we 57 00:03:42.366 --> 00:03:46.366 join these two objects together, 58 00:03:46.366 --> 00:03:50.366 so they become one object, and then go into Edit Mode, 59 00:03:50.366 --> 00:03:54.366 we can see they've still got 16 vertices. So 60 00:03:54.366 --> 00:03:58.366 let's go and combine another cube, and 61 00:03:58.366 --> 00:04:02.366 see what happens when we've got the "Automatically 62 00:04:02.366 --> 00:04:06.366 merge vertices moved to the same location" toggle turned on. And that's this 63 00:04:06.366 --> 00:04:10.366 button next to the Snapping Tools to the right. So let's generate 64 00:04:10.366 --> 00:04:13.566 another cube whilst in Edit Mode. 65 00:04:13.566 --> 00:04:16.866 And let's move it over there, 66 00:04:16.866 --> 00:04:20.866 so we can see there's 36 Edges. 67 00:04:20.866 --> 00:04:24.866 Now if we move it, so it's against this cube and let go, it 68 00:04:24.866 --> 00:04:28.866 drops down to 32 edges and it's become part of 69 00:04:28.866 --> 00:04:32.866 the thing we've snapped it to. Now there are going to be times when you do want that to 70 00:04:32.866 --> 00:04:36.866 happen, and there are going to be times you don't want that to happen. Remember 71 00:04:36.866 --> 00:04:40.866 but if you do want to go back later on, you can always go down and 72 00:04:40.866 --> 00:04:44.866 Remove Doubles in your scene, but if you know 73 00:04:44.866 --> 00:04:48.866 that you want it to be joined together straight away, so then we can lift this one up by 74 00:04:48.866 --> 00:04:52.866 a Blender unit and create a kind of a ducting type shape. 75 00:04:52.866 --> 00:04:56.866 Then, brilliant, you can do that straight away without having to go over and Remove 76 00:04:56.866 --> 00:04:58.733 Doubles and then do it. 77 00:04:58.733 --> 00:05:02.733 So one final thing with snapping! So I'm just going to 78 00:05:02.733 --> 00:05:06.733 add... I'm going to go into Object Mode here and just add 79 00:05:06.733 --> 00:05:10.733 another cube to our scene. And it's just placed it where the 80 00:05:10.733 --> 00:05:14.733 3D Cursor happens to be. I'm just going to drag it out of the way here. 81 00:05:14.733 --> 00:05:18.733 Now I'm going to turn the snapping to Vertex, and 82 00:05:18.733 --> 00:05:22.733 we're going to use that and make sure the snapping's on. Now notice to the right of it, it says 83 00:05:22.733 --> 00:05:26.733 Closest. Now what that basically means is, if I 84 00:05:26.733 --> 00:05:30.733 start to move this, so I'm going to press the G key for moving, 85 00:05:30.733 --> 00:05:34.733 and I move it close to this edge here you see it snaps. But I want 86 00:05:34.733 --> 00:05:38.733 this vertex, this one in the corner here, to snap to that one there. 87 00:05:38.733 --> 00:05:41.700 And you can see, when I'm moving it, 88 00:05:41.700 --> 00:05:44.300 it's not doing that it's moving the other one across, 89 00:05:44.300 --> 00:05:48.300 so occasionally you have to wiggle things about. Now that this vertex 90 00:05:48.300 --> 00:05:52.300 here is the closest to this one, when I try and move it and move my cursor 91 00:05:52.300 --> 00:05:56.300 over that corner, it snaps in place, and that's 92 00:05:56.300 --> 00:06:00.300 similar if you need to place something. If I need to put that 93 00:06:00.300 --> 00:06:04.300 vertex in that corner just there and 94 00:06:04.300 --> 00:06:08.300 let's say I want to place it all the way over this side, 95 00:06:08.300 --> 00:06:12.300 and I'll just use G and move it here, you see that the cube ends up right 96 00:06:12.300 --> 00:06:16.300 on the other one and I don't want that. So you need to move it to this side of it 97 00:06:16.300 --> 00:06:20.300 so that this vertex is closest, 98 00:06:20.300 --> 00:06:24.300 and then press G to move and move it across and snap it in 99 00:06:24.300 --> 00:06:28.300 place. So it can be a bit picky, at times, if one 100 00:06:28.300 --> 00:06:32.300 of your vertexes is closer than the other or edges closer. And there are a couple 101 00:06:32.300 --> 00:06:36.300 of other options here, but generally Closest is good enough. 102 00:06:36.300 --> 00:06:40.300 to get you there. So play about with snapping and you'll soon get the hang 103 00:06:40.300 --> 00:06:44.300 of which bit will snap to what, and if you need to move something like 104 00:06:44.300 --> 00:06:48.300 here. If I wanted to now move it to this one here, 105 00:06:48.300 --> 00:06:52.300 well that's not what I want at all! So I'll move it across here and 106 00:06:52.300 --> 00:06:56.300 probably going to have to shove it along here a little, and then grab 107 00:06:56.300 --> 00:07:00.300 it and move it across. I've now got it in place! So it can be 108 00:07:00.300 --> 00:07:04.300 a bit picky, but you'll get the hang of it in no time at all. 109 00:07:04.466 --> 00:07:07.500 So let's hop over to our pyramid and do a little 110 00:07:07.500 --> 00:07:09.200 challenge! 111 00:07:09.200 --> 00:07:13.200 So what would I like you to do with your pyramid? Well we're going to create that 112 00:07:13.200 --> 00:07:17.200 ramp now and merge it in with the rest of our model. So using 113 00:07:17.200 --> 00:07:21.200 the Snapping Tool, I'd like you to extrude your ramp to the right height, 114 00:07:21.200 --> 00:07:25.200 and then join up the top and bottom edges so that the 115 00:07:25.200 --> 00:07:29.200 bottom edge meets the floor and the top edge meets the actual step 116 00:07:29.200 --> 00:07:33.200 at the very top. So it's a continuous ramp from the top step 117 00:07:33.200 --> 00:07:37.200 to the floor, and I do suggest keeping it a 45 degree 118 00:07:37.200 --> 00:07:41.200 ramp. This is all part of planning our model because if 119 00:07:41.200 --> 00:07:45.200 we make it any but a 45 degree ramp the steps, that we're 120 00:07:45.200 --> 00:07:49.200 going to put on it in a bit, will be much more difficult to make, because 121 00:07:49.200 --> 00:07:53.200 we're going to have to do a different ratio to step, not 1 up and 1 122 00:07:53.200 --> 00:07:55.600 across. More on that later. 123 00:07:55.600 --> 00:07:57.933 OK, just so you guys know 124 00:07:57.933 --> 00:08:01.933 what sort of shape we're going for on the ramp, this is what my end 125 00:08:01.933 --> 00:08:05.933 scene is going to look like, with that ramp on there at 45 degrees, 126 00:08:05.933 --> 00:08:09.933 as you guys can see here. So go ahead, pause the video now, and give 127 00:08:09.933 --> 00:08:12.100 that a go! 128 00:08:12.900 --> 00:08:16.900 Welcome back! Let's hop over 129 00:08:16.900 --> 00:08:19.733 into Blender! 130 00:08:19.733 --> 00:08:22.900 So let's open up our 131 00:08:22.900 --> 00:08:24.800 pyramid. 132 00:08:25.833 --> 00:08:28.633 Let's go ahead and select our ramp 133 00:08:28.633 --> 00:08:32.633 and extrude it up! But how far do we extrude? 134 00:08:32.633 --> 00:08:36.633 Well let's have a look! Let's switch straight over into Orthodgraphic 135 00:08:36.633 --> 00:08:40.633 projection and have a look at our model from the side. So 136 00:08:40.633 --> 00:08:44.633 let's extrude up, and lets...it's going to be 137 00:08:44.633 --> 00:08:48.633 about there, so it's level with those steps. 138 00:08:48.633 --> 00:08:52.633 We're going to have to turn the Snapping Tool on, for a start. We're going to need to 139 00:08:52.633 --> 00:08:56.633 line it up with an edge somewhere. So let's 140 00:08:56.633 --> 00:09:00.633 extrude up and select this leading edge here, at the very top. 141 00:09:00.633 --> 00:09:04.633 And that's lifted it up to the right height, but unfortunately, 142 00:09:04.633 --> 00:09:06.566 it hasn't joined it 143 00:09:06.566 --> 00:09:09.933 at the top or the bottom, so we need to do that 144 00:09:09.933 --> 00:09:13.933 now. So we can select the top edge, make sure Edge Snapping is 145 00:09:13.933 --> 00:09:17.933 turned on, and literally, move one over the other 146 00:09:17.933 --> 00:09:21.933 and it's going to snap in place. Now before I do that, I'm just 147 00:09:21.933 --> 00:09:25.933 going to press Escape to cancel the move, I'm going to merge the vertices, because I do 148 00:09:25.933 --> 00:09:29.933 want that to become one object. So I'm going to move it again over 149 00:09:29.933 --> 00:09:33.933 the top there and click. 150 00:09:33.933 --> 00:09:37.933 There we go! So that's all together, that's the top bit done! However, 151 00:09:37.933 --> 00:09:41.933 let's go to the bottom one now and see what we can do there. 152 00:09:41.933 --> 00:09:45.933 Let's go all the way down here. So we can see, because we've planned our 153 00:09:45.933 --> 00:09:49.933 model to be 1 by 1 by 1, and we know this is a very 154 00:09:49.933 --> 00:09:53.933 geometric shape, it's perfect because we can just go 155 00:09:53.933 --> 00:09:57.933 straight back. Because we zoomed in we've got all these smaller squares, we can 156 00:09:57.933 --> 00:10:01.933 switch back to Increments, grab the front 157 00:10:01.933 --> 00:10:05.933 edge here, flip back to the side, and 158 00:10:05.933 --> 00:10:09.933 go down a little until we're flat with the floor, and then out 159 00:10:09.933 --> 00:10:13.933 until we're level with one Blender unit. 160 00:10:13.933 --> 00:10:17.933 And let's zoom back out. Now we've got our step completed almost. 161 00:10:17.933 --> 00:10:21.933 Now switch back to Perspective Mode. We 162 00:10:21.933 --> 00:10:25.933 need to change the normals for our step, we've inadvertently 163 00:10:25.933 --> 00:10:29.933 created something with the normals pointing inwards. I can tell that by the 164 00:10:29.933 --> 00:10:33.933 color, but you can double-check by turning the little hairs for the normals on. 165 00:10:33.933 --> 00:10:37.933 However, I'm just going to select my entire model 166 00:10:37.933 --> 00:10:41.933 and use the shortcut keys Control and N to make 167 00:10:41.933 --> 00:10:45.933 sure that all of my normals are facing outwards. I'm 168 00:10:45.933 --> 00:10:49.933 going to deselect and just check it over again. That looks perfect! 169 00:10:49.933 --> 00:10:53.933 How did you guys get on? I shall see you in the next lecture!
