1
00:00:00,000 --> 00:00:00,930
Hi everyone.
2
00:00:00,930 --> 00:00:05,220
In this lesson we are going to be looking at how to create and manipulate objects in 3D.
3
00:00:05,220 --> 00:00:07,980
So to start with, we have our default scene over here.
4
00:00:07,980 --> 00:00:10,560
And it's left-click to select our cube.
5
00:00:10,560 --> 00:00:13,080
And it gets highlighted with these yellow lines.
6
00:00:13,080 --> 00:00:14,600
And then with it selected,
7
00:00:14,595 --> 00:00:19,055
we can press X on our keyboard and then click Delete.
8
00:00:19,050 --> 00:00:21,410
So now we've deleted that cube.
9
00:00:21,405 --> 00:00:25,325
And you'll see that little written white circle with that crosses in the middle.
10
00:00:25,320 --> 00:00:27,290
That is our 3D cursor.
11
00:00:27,285 --> 00:00:31,175
And that 3D cursor can be placed anywhere in our 3D space.
12
00:00:31,170 --> 00:00:36,870
And anytime we create new objects that will be created with the 3D cursor is placed.
13
00:00:36,870 --> 00:00:38,630
Now to create a new object,
14
00:00:38,625 --> 00:00:40,805
we can either go to add at the top,
15
00:00:40,800 --> 00:00:44,270
yeah, any of these object classes.
16
00:00:44,270 --> 00:00:47,230
And then within them will find the different objects.
17
00:00:47,225 --> 00:00:52,085
Or we can press Shift a and that same menu will pop up wherever our mouse is.
18
00:00:52,085 --> 00:00:54,745
And that just makes it a bit quicker and makes it so
19
00:00:54,740 --> 00:00:57,520
that you can keep your focus in a certain spot.
20
00:00:57,515 --> 00:01:00,205
So let's press Shift a to add.
21
00:01:00,200 --> 00:01:03,530
And our 3D objects will find under the Mesh hitting.
22
00:01:03,530 --> 00:01:05,170
And you'll see you've got a plane,
23
00:01:05,165 --> 00:01:06,325
a cube, a circle,
24
00:01:06,320 --> 00:01:08,770
a UV sphere, and Ico sphere,
25
00:01:08,765 --> 00:01:11,675
cylinder, cone, tourists, grid and monkey.
26
00:01:11,675 --> 00:01:15,305
So let's create a new UV sphere.
27
00:01:15,550 --> 00:01:20,470
And you see it gets created with our 3D cursor is placed.
28
00:01:20,465 --> 00:01:22,405
Now to move our 3D cursor,
29
00:01:22,400 --> 00:01:27,160
we can simply hold down shift and then right-click anywhere in our scene.
30
00:01:27,160 --> 00:01:30,220
And you'll see our 3D cursor jumps to that spot.
31
00:01:30,220 --> 00:01:33,490
So now if our three cases every day and we press Shift
32
00:01:33,490 --> 00:01:36,430
a to add a mesh and it's linked queue.
33
00:01:36,430 --> 00:01:41,790
But this time, you'll see a Q gets created with the 3D cursor was placed.
34
00:01:41,785 --> 00:01:44,565
You can also give the 3D cursor exact x,
35
00:01:44,560 --> 00:01:45,810
y, and z coordinates.
36
00:01:45,805 --> 00:01:49,305
And to do that, we need to open the menu with a little arrow over here.
37
00:01:49,300 --> 00:01:52,750
We can click on that and you see we get this little menu over here.
38
00:01:52,750 --> 00:01:54,550
At the moment it's set to Item.
39
00:01:54,550 --> 00:01:56,760
And depending on the add-ons you have installed,
40
00:01:56,755 --> 00:01:59,365
you'll see different little tabs over here,
41
00:01:59,365 --> 00:02:01,845
but you always have Item, Tool and view.
42
00:02:01,840 --> 00:02:03,660
So let's go to View.
43
00:02:03,655 --> 00:02:06,905
And you see under view we've got a 3D cursor.
44
00:02:06,900 --> 00:02:11,140
And then we can set the location and the rotation of our 3D cursor.
45
00:02:11,135 --> 00:02:15,685
Such a receipt, the location of the 3D cursor to the center of our scene.
46
00:02:15,680 --> 00:02:18,110
We can press Shift C,
47
00:02:18,110 --> 00:02:21,820
and that makes jump back to the origin of our scene.
48
00:02:21,815 --> 00:02:25,615
And as you can see now, the location is now zeros 0000 on the x,
49
00:02:25,610 --> 00:02:29,680
y, and z, and the rotation is 0 as well, and all the axes.
50
00:02:29,675 --> 00:02:33,335
So let's say we wanted to move that up on the z-axis.
51
00:02:33,335 --> 00:02:36,825
Again, if you need to remind yourself what axes these are in,
52
00:02:36,820 --> 00:02:40,900
just look at this little image over there and that shows you z is up.
53
00:02:40,895 --> 00:02:42,985
Why is the green one going from front to
54
00:02:42,980 --> 00:02:46,750
back and x is the red one going from left to right.
55
00:02:46,745 --> 00:02:50,395
So let's move that up axis.
56
00:02:50,390 --> 00:02:53,240
Let's make that two and press Enter.
57
00:02:53,240 --> 00:02:57,460
And I can see it moved exactly two meters up on the z-axis,
58
00:02:57,455 --> 00:03:00,385
but it's still at 0 on the x and y-axis.
59
00:03:00,380 --> 00:03:02,920
So now let's create another object.
60
00:03:02,915 --> 00:03:07,775
Let's press Shift a and create another UV sphere.
61
00:03:07,775 --> 00:03:12,845
And you can see that place it exactly where our cursor is as well.
62
00:03:12,845 --> 00:03:17,855
Sometimes if we move our scene around with shift and middle mouse button,
63
00:03:17,855 --> 00:03:20,135
this are working on something over here.
64
00:03:20,135 --> 00:03:23,125
And we rotate around and want to see our spheres again.
65
00:03:23,120 --> 00:03:25,460
But it's difficult to see the back of a sphere
66
00:03:25,460 --> 00:03:28,610
because our view cameras not focused on the sphere anymore.
67
00:03:28,610 --> 00:03:30,850
To focus the camera on any object,
68
00:03:30,845 --> 00:03:36,575
you can simply select the object and then press the period key on your numpad.
69
00:03:36,575 --> 00:03:39,335
And that'll focus the camera on that object.
70
00:03:39,335 --> 00:03:41,765
Now we can zoom out a bit with the middle mouse wheel.
71
00:03:41,765 --> 00:03:43,475
And if you rotate around now,
72
00:03:43,475 --> 00:03:46,165
you'll see it rotates perfectly around that object.
73
00:03:46,160 --> 00:03:48,460
So let's do that with this sphere as well.
74
00:03:48,455 --> 00:03:49,795
Click on it to select it.
75
00:03:49,790 --> 00:03:52,440
The period key on your numpad.
76
00:03:52,870 --> 00:03:57,620
Now we can zoom out and you'll see it rotates perfectly around that object.
77
00:03:57,620 --> 00:04:02,530
Now, cool, and I will look at how to scale and move and rotate the different objects.
78
00:04:02,525 --> 00:04:06,145
I always use the shortcut keys because that makes it a lot faster.
79
00:04:06,140 --> 00:04:08,230
And so I'll show you those as well.
80
00:04:08,225 --> 00:04:10,465
But you see in our tools panel on the left here,
81
00:04:10,460 --> 00:04:11,600
we've got the move tool,
82
00:04:11,600 --> 00:04:13,940
the rotate tool, and the scale too as well.
83
00:04:13,940 --> 00:04:15,500
And you can always click on one of
84
00:04:15,500 --> 00:04:18,760
these and you'll be able to move your objects like this.
85
00:04:18,755 --> 00:04:20,855
Let's undo that.
86
00:04:20,855 --> 00:04:25,285
I prefer to stay in the select box mode and allows me to
87
00:04:25,280 --> 00:04:29,770
easily select different objects to can drag to select multiple objects.
88
00:04:29,765 --> 00:04:32,015
And then I use shortcuts to rotate,
89
00:04:32,015 --> 00:04:34,355
Move, and scale the objects around.
90
00:04:34,355 --> 00:04:36,395
So let's go through that quickly.
91
00:04:36,395 --> 00:04:38,345
So with an object selected,
92
00:04:38,345 --> 00:04:40,675
let's make this one a little bit smaller.
93
00:04:40,670 --> 00:04:42,230
So to scale an object,
94
00:04:42,230 --> 00:04:44,170
we want to press S on our keyboard.
95
00:04:44,165 --> 00:04:45,845
So let's press s1's.
96
00:04:45,845 --> 00:04:47,065
And as we move our mouse,
97
00:04:47,060 --> 00:04:48,860
you see gets bigger and smaller.
98
00:04:48,860 --> 00:04:50,660
So let's make that a little bit smaller.
99
00:04:50,660 --> 00:04:53,840
And then left-click to apply the scale.
100
00:04:53,840 --> 00:04:56,470
And Alice move that down a bit.
101
00:04:56,465 --> 00:04:58,475
Now to move an object,
102
00:04:58,475 --> 00:05:00,325
the shortcut key is G.
103
00:05:00,320 --> 00:05:02,440
And I remember that by saying,
104
00:05:02,435 --> 00:05:03,775
I want to grab the object.
105
00:05:03,770 --> 00:05:06,460
So I'm going to press G to grab and move.
106
00:05:06,455 --> 00:05:08,935
And then if I move my mouse around,
107
00:05:08,930 --> 00:05:14,050
you'll see we can move the object and then left-click to place that any way we want.
108
00:05:14,045 --> 00:05:15,985
Press Undo.
109
00:05:15,980 --> 00:05:20,720
And sometimes you only want to move the object in one specific axis.
110
00:05:20,720 --> 00:05:23,330
So let's say we wanted to move that down a bit to
111
00:05:23,330 --> 00:05:26,200
create a snowman looking object of the day.
112
00:05:26,195 --> 00:05:31,195
We can click on the tops via deselected and increase G to grab and move.
113
00:05:31,190 --> 00:05:34,610
And then we want to constrain it to the z axis.
114
00:05:34,610 --> 00:05:37,690
So we can simply press Z on our keyboard.
115
00:05:37,685 --> 00:05:41,615
And I can see it can only move up and down on the z-axis.
116
00:05:41,615 --> 00:05:46,865
So let's move that down until it's barely touching the bottom one,
117
00:05:46,865 --> 00:05:49,625
and then left-click to apply.
118
00:05:50,020 --> 00:05:56,390
And in the same way, we can move an object on the x or the y axis as well.
119
00:05:56,390 --> 00:05:59,050
So let's press G to grab and move,
120
00:05:59,045 --> 00:06:01,285
and then press X,
121
00:06:01,280 --> 00:06:02,770
which is the red axis.
122
00:06:02,765 --> 00:06:04,525
And now as we move our mouse,
123
00:06:04,520 --> 00:06:06,650
you'll see it moves on that axis.
124
00:06:06,650 --> 00:06:09,890
If you accidentally made an adjustment and you want to cancel
125
00:06:09,890 --> 00:06:13,730
that without having to click and then undo while still moving the object,
126
00:06:13,730 --> 00:06:16,850
you can right-click and goes back to where it was before
127
00:06:16,850 --> 00:06:20,170
you started moving or rotating or scaling that object.
128
00:06:20,165 --> 00:06:22,675
So let's say we selected the top sphere,
129
00:06:22,670 --> 00:06:24,640
the press S to scale.
130
00:06:24,635 --> 00:06:27,335
And then we decide, no, you don't want to scale this anymore.
131
00:06:27,335 --> 00:06:32,525
We can just right-click and it goes back to where it was not to rotate an object.
132
00:06:32,525 --> 00:06:33,565
Let's lick this cube.
133
00:06:33,560 --> 00:06:34,630
For instance.
134
00:06:34,625 --> 00:06:38,365
You could press R on the keyboard to rotate.
135
00:06:38,360 --> 00:06:41,120
And then it'll rotate around.
136
00:06:41,120 --> 00:06:44,330
And we can also constrain that to a specific axis.
137
00:06:44,330 --> 00:06:47,540
So let's say we only wanted to rotate it around the z-axis.
138
00:06:47,540 --> 00:06:49,750
We can just press Z once.
139
00:06:49,745 --> 00:06:53,465
And I would only rotates around the z-axis.
140
00:06:53,465 --> 00:06:55,415
We can always change your minds.
141
00:06:55,415 --> 00:06:56,585
Press X.
142
00:06:56,585 --> 00:07:00,385
Now it can only rotate around the x axis or press Y.
143
00:07:00,380 --> 00:07:03,070
And I will only rotate around the y-axis.
144
00:07:03,065 --> 00:07:06,525
And now we can lift click to apply our rotation.
145
00:07:06,529 --> 00:07:10,309
And as you can see, it rotated around the y direction.
146
00:07:10,310 --> 00:07:15,640
Cu is press Shift C to reset our 3D cursor to 0 shifts.
147
00:07:15,635 --> 00:07:20,225
See, the beaker and Alice add in a plane.
148
00:07:20,225 --> 00:07:25,235
Shift a go to Mesh and select playing.
149
00:07:25,235 --> 00:07:27,835
And I'll just scale that up a bit.
150
00:07:27,830 --> 00:07:31,040
So we'll press S and scale.
151
00:07:31,040 --> 00:07:32,890
And while scaling an object like this,
152
00:07:32,885 --> 00:07:35,245
Let's say we wanted to make it 10 times bigger.
153
00:07:35,240 --> 00:07:39,500
We can simply type in tin on our keyboard and then press Enter.
154
00:07:39,500 --> 00:07:41,540
So now let's move that down a bit.
155
00:07:41,540 --> 00:07:44,560
We'll press G on our keyboard to grab and move.
156
00:07:44,555 --> 00:07:48,305
And then z to constrain it to the up and down z axis.
157
00:07:48,305 --> 00:07:52,015
And then just move that down until it only barely touches
158
00:07:52,010 --> 00:07:57,890
the bottom sphere day and left-click to apply glue.
159
00:07:57,890 --> 00:07:59,980
With an object selected.
160
00:07:59,975 --> 00:08:03,095
You can also hold down Shift and click on another object,
161
00:08:03,095 --> 00:08:05,285
and they'll both get selected.
162
00:08:05,285 --> 00:08:07,585
Now if we press G to grab,
163
00:08:07,580 --> 00:08:10,300
you'll see that both move around.
164
00:08:10,295 --> 00:08:13,205
Let's right-click to cancel that.
165
00:08:13,205 --> 00:08:17,585
So let's say we wanted to move this object along this flow now,
166
00:08:17,585 --> 00:08:19,555
but not up and down at all.
167
00:08:19,550 --> 00:08:23,600
That would mean we wanted to move it in the x and the y axis,
168
00:08:23,600 --> 00:08:25,550
but not in the z-axis.
169
00:08:25,550 --> 00:08:29,380
And we can also do that by pressing G to grab and move.
170
00:08:29,375 --> 00:08:32,675
And then instead of pressing Z or X or Y,
171
00:08:32,675 --> 00:08:34,345
we can tell blender, okay,
172
00:08:34,340 --> 00:08:37,930
I want to move it in all directions except for the z-axis.
173
00:08:37,925 --> 00:08:40,555
So we can press Shift Z.
174
00:08:40,550 --> 00:08:42,860
And now we can move it anyway.
175
00:08:42,860 --> 00:08:45,370
And it will stay on that plane.
176
00:08:45,365 --> 00:08:47,425
But it will never go up and down.
177
00:08:47,420 --> 00:08:50,300
So let's put it over there and left-click to apply.
178
00:08:50,300 --> 00:08:52,930
In the same way we can move our camera around.
179
00:08:52,925 --> 00:08:54,455
So you can click on our camera,
180
00:08:54,455 --> 00:08:55,985
press G to grab,
181
00:08:55,985 --> 00:08:57,455
and we can move that around.
182
00:08:57,455 --> 00:08:59,455
But that makes it a bit difficult sometimes.
183
00:08:59,450 --> 00:09:01,240
So let's right-click to cancel that.
184
00:09:01,235 --> 00:09:04,055
And if you go into camera view with numpad 0,
185
00:09:04,055 --> 00:09:06,445
you'll see what the camera view is seeing.
186
00:09:06,440 --> 00:09:09,680
And that's this little frame that we see over there.
187
00:09:09,680 --> 00:09:12,290
So let's say we wanted to move this camera alphabet.
188
00:09:12,290 --> 00:09:14,800
Now, if we scroll with our mouse wheel,
189
00:09:14,795 --> 00:09:18,965
you'll see it doesn't change the actual frame size of our camera.
190
00:09:18,965 --> 00:09:21,905
And if you try to rotate around with the middle mouse button,
191
00:09:21,905 --> 00:09:24,125
you'll see it goes out of camera view again.
192
00:09:24,125 --> 00:09:27,645
So there's pre 0 and an unpaid again to get into camera view.
193
00:09:27,645 --> 00:09:30,565
Now another little side menu over here.
194
00:09:30,565 --> 00:09:34,995
Remember you can bring that up by pressing N on your keyboard.
195
00:09:34,990 --> 00:09:39,220
Will see in the View tab this eye view Locke section.
196
00:09:39,220 --> 00:09:42,180
And under that there's a camera to view checkbox.
197
00:09:42,175 --> 00:09:44,235
If we enable that now.
198
00:09:44,230 --> 00:09:49,030
And we scroll with our mouse wheel to see the camera actually moves in and out.
199
00:09:49,030 --> 00:09:51,060
And if you hold down the middle mouse button,
200
00:09:51,055 --> 00:09:55,725
we can move the view of the camera so that we can frame our camera.
201
00:09:55,720 --> 00:09:58,200
So we want to do something like that.
202
00:09:58,195 --> 00:10:02,295
And we can also move by holding Shift and clicking with the middle mouse button.
203
00:10:02,290 --> 00:10:05,760
And then we can drag and move and then just let go.
204
00:10:05,755 --> 00:10:07,975
And if we're happy with the placement of a camera,
205
00:10:07,975 --> 00:10:09,655
we can just unselect
206
00:10:09,655 --> 00:10:13,725
that little box and we don't accidentally change our camera view again.
207
00:10:13,720 --> 00:10:16,860
Now we can go around and work on different parts of our scene.
208
00:10:16,855 --> 00:10:19,125
And if you want to go back into camera view,
209
00:10:19,120 --> 00:10:21,280
you just press 0 on your numpad.
210
00:10:21,280 --> 00:10:24,640
And again, if you want to change the actual view of the camera,
211
00:10:24,640 --> 00:10:27,630
we can just select camera to view.
212
00:10:27,625 --> 00:10:31,635
And now you'll see it changes the actual view of our camera again.
213
00:10:31,630 --> 00:10:36,150
We can also hold down control to move in and out smoothly like this.
214
00:10:36,145 --> 00:10:39,735
And now we can perfectly frame your objects in your scene.
215
00:10:39,730 --> 00:10:41,950
There we go. So this is able,
216
00:10:41,950 --> 00:10:49,410
this so that we don't accidentally move that around and have a press F2 to render.
217
00:10:49,405 --> 00:10:53,885
You see we get the exact same framing that we had in our camera.
218
00:10:53,880 --> 00:10:55,930
Cool, and that's it for this lesson.
219
00:10:55,925 --> 00:10:58,725
In the next lesson, we're going to be looking at how to manipulate
220
00:10:58,729 --> 00:11:01,789
the basic shapes like our cube and sphere that we have here.
221
00:11:01,790 --> 00:11:06,990
And turn them into more complex shapes that we can use to create our objects.
