Blender is a 3D computer graphics software used for creating animated films, visual effects, art, 3D printed models, and video games. It has a navigation system that heavily relies on the middle mouse button (MMB). To rotate the view, click and drag the MMB on the viewport's area. To zoom, use the Ctrl and Alt keys and move the stylus up or down. To pan, press Alt and Shift and move the stylus.
| Characteristics | Values |
|---|---|
| Rotate the view | Click and drag MMB on the viewport’s area |
| Change the point of interest | Click a point with Alt-MMB |
| Align the view to an axis | Hold Alt and drag with MMB in a certain direction |
| Perform an orbit | Drag with MMB and then hold Alt |
| Change the viewing angle | Use Numpad8 and Numpad2 to go up and down, or Numpad4 and Numpad6 for left and right |
| Switch to the opposite side of the view | Press Numpad9 (rotates the camera 180° around the Z axis) |
| Zoom | Press Ctrl+Alt and move the stylus up or down |
| Pan | Press Alt+Shift and move the stylus |

What You'll Learn
Zoom in and out with Ctrl+Alt
Blender's navigation tools are heavily dependent on the middle mouse button (MMB). To zoom in and out with your mouse, hold down Ctrl and drag the MMB forward and backward. Alternatively, if you have a wheel mouse, you can simply zoom in and out by rotating the wheel.
If you are using a stylus, you can enable "emulate 3 button mouse" to draw with one hand and zoom in and out with the other by pressing Ctrl+Alt and moving the stylus up and down.
To zoom in and out in discrete steps, you can use the hotkeys NumpadPlus and NumpadMinus.
If you get lost in 3D space, the hotkey "Home" will change the view so that you can see all objects, while NumpadPeriod zooms the view to the currently selected objects when in perspective mode.

Rotate with Alt
To rotate with Alt in Blender, you can perform an orbit around the point of interest by holding Alt and dragging with the middle mouse button (MMB). This will also snap to the world axes and the diagonals between them.
Additionally, you can make a specific point the central point of orbit by clicking it with Alt-MMB. Holding Alt and then dragging with MMB in a certain direction will also align the view to an axis and make it orthographic.
It's worth noting that the default behaviour of Blender for loop selecting is Alt+Right Mouse Button (RMB). However, some users may prefer to use separate shortcuts for loop selecting and rotating the view.
For precise rotations, you can also input the exact degree of rotation. Press R, followed by an axis key, and then type the desired degree. For example, RX45 will rotate an object 45 degrees along the X-axis.

Pan with Alt+Shift
To pan with Alt+Shift in Blender, you need to first enable the "Emulate 3 Button Mouse" option in your user preferences. This is particularly useful if you are working with a mouse that doesn't have a middle mouse button or if you are using a pen and tablet interface.
Once you have enabled the "Emulate 3 Button Mouse" option, you can emulate the middle mouse button by pressing Alt+left-click. Now, to pan with Alt+Shift, simply press and hold the Alt and Shift keys together, along with the left-click button on your mouse or stylus.
While holding down these keys, you can move your mouse or stylus to pan the view in the 3D Viewport. This allows you to navigate and adjust your viewpoint within the Blender interface.
It is worth noting that some users have reported issues with panning using the Shift+MMB combination, where it becomes very slow or stops working altogether. In such cases, you can try solutions like hitting the "period" key on the number pad, unlocking the view using Alt-Numpad, or reloading the factory settings to resolve the issue.

Dolly with Shift-Ctrl
Dolly Zoom is a feature in Blender that allows you to adjust the perspective of your camera view, helping you frame your renders and animations perfectly. It uses exact mathematical formulas to reposition your camera while adjusting the perspective, ensuring that the camera remains focused on the 3D cursor.
To use Dolly Zoom, first, set a camera in your scene as the active one. Then, place the 3D cursor at the point you wish to keep in focus. Next, activate the tool in Object mode via the menu View > Navigation > Dolly Zoom & Truck Shift or by using a custom hotkey that you can set up. You can switch between dolly-zoom, truckshift-x, and truckshift-y modes using the D, X, and Y keys, respectively.
While in camera view (Numpad 0), you can use Shift+F to position the camera in the first-person view. You can then use the W, A, S, and D keys to fly around. When using Dolly Zoom, holding down Ctrl+Shift and dragging the middle mouse button will move the view forwards and backwards, providing a seamless movement. This is different from regular zoom, which is performed by holding Ctrl and dragging the middle mouse button.
Additionally, when using Dolly Zoom, you can enter "type-in mode" by typing any number while in the adjustment mode. This mode allows you to input the exact value for the adjustment being made, providing precise control over your camera movements.

Change viewing angle with Numpad
To change the viewing angle in Blender, you can use the numpad on your keyboard. The Numpad8 and Numpad2 keys correspond to vertical mouse dragging and are used to change the viewing angle vertically. On the other hand, Numpad4 and Numpad6 rotate the scene around the global Z-axis from your current viewpoint. These keys can be used in combination with Ctrl to achieve the same result as dragging the middle mouse button (MMB) up and down or left and right.
For those without a middle mouse button, an alternative is to hold Shift-Alt while dragging with the left mouse button (LMB). This will achieve the same panning effect as using the MMB. Additionally, you can use the Ctrl and Shift keys in combination with the numpad keys for more precise control over the viewing angle. For example, using Ctrl-Numpad8, Ctrl-Numpad2, Ctrl-Numpad4, and Ctrl-Numpad6 will result in discrete steps of movement, allowing for more accurate adjustments to your viewpoint.
It is worth noting that Blender's navigation is heavily dependent on the middle mouse button. However, these numpad shortcuts provide a convenient way to navigate the 3D space without having to reach for the mouse. With these key combinations, you can easily adjust your viewpoint and continue working with your right hand on the stylus or mouse.
In addition to changing the viewing angle, you can also use the numpad to zoom in and out. By holding down Ctrl and pressing NumpadPlus, you can zoom in, and with NumpadMinus, you can zoom out. These hotkeys provide a quick way to adjust your field of view without interrupting your workflow.
