[01:35] First, we need to know how the window of Blender is made.
  首先，我们需要知道 Blender 的窗口是如何制作的。

[01:39] How to use the logic of its window panel to improve your productivity.
  如何利用其窗口面板的逻辑来提高你的生产力。

[01:43] Let's look at the main interface first.
  让我们先看看主界面。

[01:44] In the last class, it consists of four panels.
  在上节课中，它由四个面板组成。

[01:47] About the window panel of Blender,

[02:09] there are script panels, and there are some data panels.
  有脚本面板，还有一些数据面板。

[02:11] These panels can be replaced.

[02:32] In fact, this is to let you understand that
  事实上，这是为了让你明白

[02:34] every window panel can be changed into other functions.
  每一个窗口面板都可以变成其他功能。

[02:38] If you understand this, you can understand that
  如果你理解了这一点，你就能明白

[02:40] the other labels at the back are actually
  后面的其他标签实际上

[02:42] all transferred from these windows.
  都是从这些窗口转移过来的。

[02:44] For example, the label page of Blender

[02:46] and the label page of Blender,
  和Blender的标签页，

[02:48] the big-scale window on the left is the same as the attribute bar.

[03:04] you will find that it looks the same as the label bar of my sculpt.
  你会发现它看起来和我的雕塑的标签栏一样。

[03:07] The first feature of the panel we just talked about is replaceable.
  我们刚才讨论的面板的第一个特点是可替换的。

[03:11] Next, let's talk about its second feature, which is detachable.
  接下来，我们来谈谈它的第二个特点，那就是可拆卸的。

[03:13] You can add or subtract a panel from the interface by yourself.
  你可以自己从界面中添加或删除一个面板。

[03:18] How to add and subtract?
  如何添加和删除？

[03:20] The simplest and easiest way to remember is to move the mouse to the four corners of each window.
  最简单易记的方法是将鼠标移动到每个窗口的四个角落。

[03:24] When it shows an extra number, you can drag it to get a new window.
  当它显示一个额外的数字时，你可以拖动它来获得一个新窗口。

[03:28] How to remember?
  如何记住？

[03:29] When an extra number appears, you can drag it to another window.
  当出现一个额外的数字时，你可以将其拖到另一个窗口。

[03:32] You can merge it.

[03:33] For example, if an extra number appears on this corner,
  例如，如果这个角落出现一个额外的数字，

[03:35] you can drag it to the left and it will merge it.
  你可以将其拖到左边，它就会合并。

[03:38] Then you can drag it in your own direction.
  然后你可以将其拖向自己的方向。

[03:40] It will separate itself.

[03:48] There is another way.
  还有另一种方法。

[03:49] You can put the mouse on the division line.
  你可以将鼠标放在分割线上。

[03:51] When a vertical division appears on the right, it will start to move.

[03:54] It will show a division line.
  它会显示一条分割线。

[03:56] When a horizontal division appears, it will move.
  当出现水平分割时，它将移动。

[03:58] Actually, I don't think this method is as easy as the one I just talked about.
  实际上，我认为这种方法不如我刚才讲的那种容易。

[04:01] It's easy to remember that you can drag an extra number in your own direction,
  容易记住的是，你可以将一个额外的数字拖向自己的方向，

[04:03] it will separate, and it will merge in the direction of others.

[08:25] Move the origin to the bottom of the cube.
  将原点移动到立方体的底部。

[08:29] At this time, remember to turn off the effect origin in the option.
  此时，请记住在选项中关闭影响原点。

[08:33] Otherwise, you can't move the model.
  否则，你无法移动模型。

[08:35] Then click G.

[09:48] So don't worry.
  所以别担心。

[09:49] Now let's talk about how to make your mouse more useful.
  现在我们来谈谈如何让你的鼠标更有用。

[09:52] For example, if I zoom in and out here,
  例如，如果我在这里放大和缩小，

[09:56] it will zoom in and out with the center of the view.
  它将随着视图中心进行放大和缩小。

[10:00] You can go to the setting of the sidebar.
  你可以去侧边栏的设置。

[10:02] Open the zoom to the position of the mouse.
  打开鼠标位置缩放。

[10:04] Then it will zoom in and out with the center of the mouse.
  然后它将随着鼠标中心进行放大和缩小。

[10:09] This will make it easier for you to do the case later.
  这将使您以后更容易处理该案例。

[10:12] For example, if I click on the back of the mouse,
  例如，如果我单击鼠标的背面，

[10:14] it will zoom in and out with the back of the mouse.
  它将随着鼠标的背面进行缩放。

[10:16] The second setting is about the axis of the mouse.

[10:25] We click on this object.
  我们单击此对象。

[10:26] We want to use this object as the axis of rotation to observe the view.

[10:30] But now it seems that it can't do that.
  但现在似乎做不到。

[10:33] For example, the axis of rotation.
  例如，旋转轴。

[10:34] In theory, it should rotate with this axis.
  理论上，它应该围绕此轴旋转。

[10:36] But it doesn't actually rotate with this axis.
  但实际上它并没有围绕此轴旋转。

[10:38] We can click on the setting of the sidebar.
  我们可以单击侧边栏的设置。

[10:41] Then we open the object rotation.
  然后我们打开对象旋转。

[10:44] At this time, you choose this column.

[14:36] If you remember the x,
  如果你记得x，

[14:37] you can't see the difference.
