In fact, you’ve already had exposure to a couple types of region in this chapter: the header, the Toolbar, and the Sidebar. This section focuses on the latter two in more detail.
Flanking either side of the 3D Viewport is a Toolbar on the left, and on the right is a region for modifying the properties of the 3D Viewport, referred to as the Sidebar.
The Sidebar
You can toggle the visibility of the Sidebar by choosing View ⇒ Sidebar in the header or by pressing N (for iNformation) while your mouse cursor is in the 3D Viewport. In fact, quite a few editors in Blender have a Sidebar. And with the exception of the Text Editor, which uses Ctrl+F (because it would be annoying if the Sidebar popped up every time you typed an N in the Text Editor), you can consistently open all of them by using the N hotkey.
In the 3D Viewport, the Sidebar serves three primary purposes, each designated by a specific tab:
Item: From the Item tab, you can directly modify your selected object by typing in explicit location, rotation, and scale values within the Transform panel.
Tool: The Tool tab has much the same content you would see in the Active Tool context of the Sidebar. This tab is particularly useful if you’re working with a maximized 3D Viewport (Shift+Spacebar). I tend to use it a lot when sculpting and painting.
View: The View tab is dedicated to customizing your 3D Viewport. From here, you can control features like the viewport camera (which is different from the scene camera), the location and orientation of the 3D cursor, and the collections that are visible in the 3D Viewport. Chapter 4 has more on working with collections. The View tab is also where you can control annotations in the 3D Viewport. There’s more on annotations later in this chapter.
The Toolbar
The Toolbar is a new feature in Blender, as of version 2.80. It allows you to have a workflow similar to other computer graphics applications where you first select a tool and then use that tool to act on an object or selection. Depending on what mode you’re in (Edit mode, Object mode, Sculpt mode, and so on), you will have a whole bunch of tools or only a handful.
Tool Settings
The controls in the Topbar are really handy, but they’re also available in the Sidebar as well as the Active Tool tab of the Properties editor. Personally, I tend to hide the Topbar to save screen space, but if you’re used to programs like Photoshop or Krita, you may find the Topbar more familiar.
The Last Operator panel
There’s an additional quasi-region in the 3D Viewport that’s extremely useful. At the bottom left of the 3D Viewport is the Last Operator panel. If you’ve just opened Blender, you won’t see this panel at all (because you haven’t done anything yet). However, if you perform an action in Blender — also known as an operator — like moving your selected object or adding a new object, this panel updates to display values relevant to that operator. Using this panel, you can perform a quick, rough operation and then tweak it to be more precise. For example, if you add a UV Sphere to your scene (Add ⇒ Mesh ⇒ UV Sphere), Blender adds a UV Sphere object to your scene at the location of the 3D cursor with 32 segments and 16 rings. Using the Last Operator panel, you can not only adjust the location of your new sphere, but you can also modify the number of segments and rings it has. You can see more on how the Last Operator panel is used in Chapter 5.

Collaborating (with others and yourself) with annotations
.blend
files as reminders so I don’t have to mentally keep track of every random design decision I made while working.
Blender’s annotation feature gives you the ability to leave these kinds of notes in your .blend
files, right in the editor you’re working in. The controls for annotations are at the bottom of the View tab of the Sidebar. Expand the Annotations panel and you should see a button labeled New. Click that button and the panel will expand to look like what’s shown in Figure 2-11.
The list box can hold multiple layers of annotations. By default Blender pre-populates this list box with a single layer named Note. To the left of the layer is a color swatch that dictates the color of any annotations on that layer. Add and remove layers by using the plus and minus buttons to the right of the list box. Below the layer list box is a Thickness slider that controls the thickness of any annotations you make on that layer.
The easiest way to make a new annotation is to use the Annotate tool in the Toolbar. Activate this tool by clicking and you’re instantly able to start writing and drawing
