===== Navigation =====

Being able to look and move around in the 3D viewport intuitively is necessary to work in any 3D application.\\
**Orbit**: rotate around a point.\\
**Pan**: move the scene without rotating.\\
**Zoom**: see more or work on details by zooming in and out.\\

You can use the user interface gizmos on screen but this is a little slow. Shortcuts are faster.

^ Shortcut ^ Function ^
| 0 | Camera view |
| 1 | Front |
| 3 | Right |
| 7 | Top |
| Numpad . or personalized key | Frame selected |
| press scrollwheel | Orbit |
| Alt + left mouse button | Orbit |
| Alt + shift + left mouse button | Pan |
| Scroll wheel | Zoom |


**No numpad?**\\
Change preference: ''Edit > Preferences > Input > Emulate numpad''\\
Use the numbers on the top of your keyboard instead. You might have to press shift if you have azerty for example.\\

Also, set a custom shortcut for 'Frame Selected': ''View > Frame Selected'', Right mouse click: change shortcut (for example '';'')

**Don't like pressing the scrollwheel to orbit?**\\
Change preference:  ''Edit > Preferences > Input > Emulate 3 button mouse'' \\
Then orbit by pressing alt + left mouse button



===== Transformations =====

Unique behaviour: with an object selected, press a shortcut, move mouse, press Enter to commit, or escape to cancel.

^ Shortcut ^ Fuction ^
| G | Grab (move object around) | 
| R | Rotate | 
| S | Scale |
| Option + G | Reset move |
| Option + R | Reset rotate |
| Option + S | Reset scale |

**Accept transformation:** Press enter.\\
**Cancel transformation:** Press escape.\\

**Constrain to global axes**:\\ 
Press the X, Y or Z key **once** after a transform shortcut.\\ 
For example: G + X + enter (move on the global x-axis).\\ 

**Constrain to local axes:**\\ 
Press the X, Y or Z key **twice** after a transform shortcut.\\ 
For example: R + Z + Z + enter (rotate on the local z-axis).\\ 

Shift + mouse movements while doing a transformation = finer definition.\\
CTRL + mouse movements: snap to grid.\\
Numeric entries are possible: with object selected, press r to rotate, and type 90 to rotate 90°.\\

===== Mesh manipulation =====
  * Shortcut to toggle between object and edit mode: tab
  * Vertexes, edges, faces
  * Transforms work the same with vertexes, edges and faces as with entire 3D objects
  * Use proportional editing for smooth changes to a 3D model: shortcut ''o'' + scroll to adjust the influence.

===== Selections =====
^ Shortcut ^ Fuction ^
| A | Select all |
| Alt + A | Deselect all |
| Cmd + I | Invert selection |

In edit mode: 
^ Shortcut ^ Fuction ^
| L | Select linked | 
| Double click between vertices | Select edge loop |
| Select first vertex, then cmd + select second vertex | Select shortest path | 


Using solid shading: selection only on the front of the object.\\
In wireframe mode: selection through object.\\
