Blender 3D: Noob to Pro/3D View Windows

3D View windows are used to visualize 3D scenes. You’ll do a lot of work in these windows, so you will need to learn your way around.

In this module, you'll learn:
 * to recognize 10 things commonly seen in viewports
 * to tell which mode Blender is in
 * how to change viewport options and viewpoints
 * how to position the 3D cursor

You'll also learn the fundamentals of:
 * visibility layers

The Viewport and its Contents
Aside from its header, the remainder of a 3D View window is its. You use viewports any time you need an up-to-date view of the scene you're working on.

Viewports are busy places. Go on a scavenger hunt and see what you can find in a simple viewport.

(If you're unsure what means, please review the Keystroke, Button, and Menu Notation module.)
 * 1) Launch Blender.
 * 2) Just so we're all looking at the same scene, load the factory settings using File &rarr; Defaults ->  Load Factory Settings.
 * 3) Confirm the “Load Factory Settings” popup with  (or ).
 * 4) If the NumLock indicator on your keyboard is unlit, press  so that numpad hotkeys will work properly.

You should see something like this:

A Virtual Scavenger Hunt
Look at the default scene and find the following eight items:

1. a solid gray cube with orange edges.
 * In the Center
 * This is the, your first Blender object!

2. Three arrows, one red, one green and one blue, their tails joined to a white circle
 * This is not an object (part of your model/scene), but part of Blender’s user interface for manipulating objects. It is the, also known as the.
 * The arrows represent the directions of the, and  axes of the currently chosen  coordinate system. Initially this is the.
 * The circle represents the center of the selected object (the cube).
 * If you don't know what the "global coordinate system" is, please review the module on Coordinate Spaces in Blender.


 * It's possible that a tool is active. Press  to cancel any tool action.
 * Another possibility is that the manipulator has been disabled:
 * Toggle it on or off with.

3. A red-and-white striped circle with black cross-hairs
 * This is not an object. It is the 3D Cursor, which indicates where newly-created objects will appear in the scene.
 * The cursor is similar to the insertion point in a text editor, which indicates where new text will be inserted in a document.

4.
 * In the Lower Left Corner
 * This is not an object. It is the mini axis, and its orientation matches that of the global coordinate system, with the usual conventions: red for X, green for Y and blue for Z. Think of it as a little compass, reminding you which way is left/right, front/back and up/down.

5. The notation "(1) Cube"
 * This is not an object. It is, indicating that:
 * You're viewing the first frame of an animation.
 * and
 * The current or most recently selected object is named "Cube".

6. The notation “User Persp”
 * In the Upper Left Corner
 * This is not an object. This tells you which mode the viewport is in. The first word will change if you select one of the perfect views or the camera view (see below), otherwise it just says “User”, and the second word is “Persp” or “Ortho” to indicate whether this is a perspective or orthographic view.

7. A black round thing that resembles a sun symbol
 * To the Right of Center
 * This represents a lamp, a light source for the scene. (It is an object.)

8. A pyramidal wireframe item
 * This represents a camera, a viewpoint that can be used for rendering. (It too, is an object.) The camera is looking at the base of the pyramid. The solid triangle attached to one side of the base is to remind you which way is up in the image that the camera takes.
 * On a small display, the camera might initially lie outside of the viewport and thus be invisible. In that case,  to zoom out until it becomes visible.

9. A dark gray background, divided into squares by lighter lines. This is the, which you can (but don’t have to) use as a ground plane for positioning your models.
 * Throughout
 * Each grid square is one blender unit (or BU) on a side. A BU can be whatever you wish, e.g. an inch, a centimeter, a mile, or a cubit.  Blender lets you choose your scene scale in the Scene tab of the Properties Panel.

10. Three mutually perpendicular coloured lines associated with the grid floor: the red and green ones lying horizontally in the floor and the blue one running vertically. These are the global coordinate axes for orienting your scene. Red is the X-axis, green the Y-axis, and blue the Z-axis.
 * In Blender 2.67a, you can't see the blue line for Z-axis here, but you can see it in Front or Side view.

Modes
Blender has many modes, i.e. settings that affect its behavior, and this is especially true of the 3D View window.

Sometimes it's not obvious which mode is active. This leads to mode errors where Blender will do something you didn't expect because you thought it was in one mode and it was actually in another.

The function performed by a hotkey or mouse button can depend on:
 * what mode the user interface is in,
 * whether the keyboard is in NumLock mode,
 * which window is active,
 * the mode the active window is in,
 * which item or items are selected,
 * whether you've initiated a hotkey sequence.

It helps to recognize the common modes and how to get out of them.

Object Mode vs. Edit Mode
The 3D View windows are normally in Object Mode. In this mode:
 * The mouse pointer is the default arrow normally used on other programs.
 * is used to select objects in the scene.
 * In versions 2.8 and above Use to select objects in the scene

If there are objects in the scene, you can get into five other modes:
 * Edit Mode: used to edit the shapes of objects
 * The mouse pointer is a thin inverse-video cross.
 * is used to select vertices, faces or edges of the current object.
 * Press to enter/exit this mode.
 * Sculpt Mode/Vertex Paint/Texture Paint/Weight Paint
 * The mouse pointer is now a thin, orange (white in Texture Paint) circle.

These modes are also indicated by a menu in the 3D View header. You can use this menu to change modes.



These modes are a setting shared by all 3D View windows. In other words, when you change the mode in one window, any other 3D View windows change mode also.

Solid vs. Wireframe
By default, the 3D View window draws objects using the Solid drawtype, in which surfaces are opaque. To toggle between Solid and Wireframe drawtype (edges only, no faces) for a particular viewport:
 * 1) Activate the 3D View window

Alternatively, you can choose these and other drawtypes from the "Viewport shading" menu in the 3D View window header.
 * 1) Press.

Orthographic vs. Perspective
By default, viewports draw orthographic views. To toggle a viewport between orthographic and perspective views:
 * 1) Activate the 3D View window.
 * 2) Press.

(If you're unsure what the difference is, please review and .)

Note this perspective versus orthographic setting for the 3D viewport is completely separate from the similar setting in the camera properties. The former takes effect while you’re working on the model, the latter when you render.

So why have a separate setting for the 3D view? Because certain aspects of modelling are easier in one view than another. If the final render will be using perspective, then showing perspective in the 3D view naturally gives you a better idea of how the final render will look. But perspective foreshortening can sometimes make it hard to ensure the model has the proper shape, which is why there is the option to switch to orthographic view.

... you should activate the View Name option. This is enabled by default and causes the name of the current view ("User Persp", for instance) to appear in the upper left corner of every viewport. If there is no text, then you can enable it by:
 * 1) Accessing the User Preferences window.
 * 2) Click on the Interface tab.
 * 3) Enable View Name.

Changing Your Viewpoint, Part One
Each viewport has a viewpoint, which takes into account:
 * the location of the viewer in the 3D scene (There doesn't need to be an object at that location.)
 * the direction the viewer is looking
 * the magnification (or zoom factor) used

Changing your viewpoint allows you to navigate your way through a 3D scene.

We'll start with three very basic techniques:
 * Zooming
 * Orbiting/View Rotation
 * Perfect Views.

Additional techniques will be covered later in this module.

Zooming
Blender offers several ways to zoom in and out:
 * Use
 * Click and drag vertically with.
 * Use and  to zoom in and out in small increments.

Note the following limitations of Blender's zoom feature:
 * If the viewport is in orthographic mode, Blender zooms as if looking through a telescope. You can increase the magnification, but the viewpoint's location doesn't change.  For this reason, you cannot zoom into or through objects in orthographic mode.
 * If the viewport is in perspective mode, Blender zooms to the center of the viewport. The viewpoint can pass through objects, but can't pass beyond this point, no matter what you do. Zooming only gets slower and slower and slower.  If the center of the viewport is somewhere you don't expect, zooming may appear to be broken.

Orbiting and View Rotation
Let's fly around the default cube, viewing it from different angles. In this way you'll see that it really is a cube, centered on the origin, half above the X-Y plane and half below it.


 * 1) Activate the 3D View window by placing the mouse pointer inside it.
 * 2) Now you can:
 * 3) *Click and drag with to orbit freely around the center of the view.
 * 4) *Use to rotate the viewpoint vertically around the center of the view.
 * 5) *Use and  to rotate the viewpoint vertically around the center of the view in 15-degree increments.
 * 6) *Use to rotate the viewpoint around the Z axis.
 * 7) *Use and  to rotate the viewpoint around the Z axis in 15-degree increments.

If this is all very confusing for you, don't worry! You'll learn as you get more experience.

When you are finished flying around the cube, you can restore the original view by reloading the factory settings with File &rarr; Load Factory Settings.

You may have pressed number keys above the letters instead of the ones on the numpad. If you do, the default cube will vanish. This is because the scene consists of multiple layers. The default cube is in layer 1, and you've told Blender to switch to the layer of the number you just pressed. The selected object (the cube in this case) remains in layer 1, which is no longer visible. For instance, tells Blender to switch to layer 2. To switch to layer 1 again, press. You can view the different layers by clicking on the little squares on the layer map:

The Shift + Alt + Scroll and Ctrl + Alt + Scroll do not work for me with factory settings in Blender 2.92.0 (Doesnt Work Counter: 2.People)

Perfect Views
It's often useful to get a perfect view of a scene, i.e. to view it along one of the main axes, with the other two main axes oriented up-down and left-right.

The following screenshot shows all three perfect views plus camera perspective for the Suzanne primitive:



This layout is used so often, it has a keyboard shortcut:.

Positioning the 3D Cursor
Positioning the 3D cursor is a very basic operation, yet one that many beginners find challenging. It touches on an issue common to all 3D graphics software: "How do you specify points in a 3D scene when we can only see two dimensions at a time?"

Basic Technique

 * 1) Go into either Object Mode or Edit Mode.
 * 2) Move the mouse pointer to the desired position (in any viewport).
 * 3) Click.

Two Challenges
Challenge #1. Using only tools presented thus far, try positioning the 3D cursor on the virtual camera.

Try it!

When you're done, check your work by orbiting the camera.

Perhaps you thought you were done when you clicked on the camera. But the moment you changed your viewpoint, you probably found that the 3D cursor was actually behind (or in front of) the camera.

Hints:
 * Try positioning the cursor in two different perfect views.
 * Use orthographic, not perspective, view.

Challenge #2. Using only tools presented thus far, try repositioning the 3D cursor at the origin (that is, at the center of the cube).

As before, check your work by orbiting the cube. Don't spend too much time on this.

"I found that I would select the cube when left clicking on it in object mode, if the "Use 3d transform manipulator" button was enabled. To toggle this off, you click on the gray pointing hand in the 3d panel header, or (Ctrl Space)."

"When you want the cursor back into the cube, just select the camera with RMB, put the cursor into the cube following the steps above, and re-select the cube with RMB."

"I've discovered it helps a lot if you are in Object Mode and not in Edit Mode. I wrote the following before discovering this: The problem with this exercise, for me, is that left clicking on the cube selects the cube instead of moving the 3d cursor. If I click on the cube outside of its central white circle I can get the cursor to move there, but only to outside of this white circle, and even then this only works sometimes."

"I failed at this until I had zoomed in close enough to the cube. When I was too far zoomed out I kept selecting the cube rather than creating an edit point."

"I had the same problem and found it was because the cube was selected. I made sure I was in object mode, right clicked on the camera to select the camera instead of the cube, and I could then position the edit point in the cube. However, doing this messed up the next part of the tutorial because you cannot switch into edit mode with the camera selected! Perhaps the suggestion of trying to put the 3D cursor in the cube should be dropped as it raises too many questions at this stage."

"You can deselect all by pressing the AKEY or the select button in the 3D View."

"Use wireframe mode works better to get the cursor in."

"To get it back in the cube: 1) Make sure you're in object mode. 2) Select the cube. 3) Object > Snap > Cursor to selection (cursor refers to the 3D cursor here) so it puts it right in the middle of the cube."

"I think it's an essential point to note that in order to place the cursor inside the cube, the cube must NOT be selected. AKEY was probably the best way to deselect the object."

"If I remember correctly, undo history gets cleared when you switch between object and edit mode."

"I wasted a lot of time here. Thank you to the reader who suggested (on the 3D view header) Object > Snap > Cursor to selection. It was the only thing that worked to get the cursor visible again and placed where clicked."

"I missed the point of the exercise first time around. You can't set a 3D point on a 2D screen without technique. Orthographic views are crucial. I am just learning, but take that, at least, away from it."

"Positioning the 3D cursor in othographic views always made it snap to the cube surface, making it impossible to center precisely. Fix this by disabling "Cursor Depth" on the "interface" tab under "User Preferences".

"The phrase check your work by orbiting the camera needs additional clarification, such as a referenced section or the precise commands to use."

More Ways to Position the Cursor


Here's an easy way to position the cursor at the center of an object:
 * 1) Make sure Blender is in Object Mode, with the object selected.
 * 2) Move the mouse pointer to any 3D View window.
 * 3) Snap the cursor to the selected object using either:
 * 4) * &rarr; Cursor to Selected
 * or
 * 1) * Object &rarr; Snap &rarr; Cursor to Selected

Here's 2 easy ways to relocate the cursor to the scene's origin (0, 0, 0):
 * 1) Move the mouse pointer to any 3D View window.
 * 2) Press  to reset the cursor to the origin.
 * 3) * Note that this also changes the view location, meaning that when you zoom in, you won't zoom in to the scene origin.
 * 4) A better way is to click Object &rarr; Snap &rarr; Cursor to Center
 * 5) * You can also do this by &rarr; Cursor to Center.

Changing Your Viewpoint, Part Two
Now you'll learn some additional techniques for obtaining the view you want:
 * Panning
 * Centering
 * Jumping to the camera's viewpoint
 * Zooming in on a selected area

Panning
When you orbited the cube, the viewpoint's position and direction both changed at the same time. You also can shift the viewpoint up-down or left-right without changing its direction. (This is similar to the side-scrolling effect in the classic Mario and Sonic video games.)

This is called panning, and it's an important skill to master. Try it now:


 * 1) Activate a 3D View window by placing the mouse pointer inside it.
 * 2) Now you can:
 * 3) *Use to pan up and down.
 * 4) *Use and  to pan up and down in small increments.
 * 5) *Use to pan left and right.
 * 6) *Use and  to pan left and right in small increments.
 * 7) *Click and drag with or  to pan freely in the viewplane.

You will likely find this to be a distraction in some cases. To move the viewpoint position back to the center, snap the cursor to the center, then click View &rarr; Align View &rarr; Center View to Cursor. You could also snap the cursor to the center then press.

In versions ≥2.74 you can also use to center the view to the cursor.

Centering
When you zoom or rotate the view, you always zoom or rotate around the center of the view.

To make sure everything in your scene is visible:
 * 1) Press.

To center the view on an arbitrary point:
 * 1) Move the 3D cursor to the point of interest.
 * 2) Verify the cursor position from a second viewpoint.
 * 3) Press + to center the view.

To center the view on an object in the scene:
 * 1) Make sure Blender is in Object Mode.
 * 2) Zoom out until the object is in the viewport.
 * 3) If any objects are selected, use  (or Select &rarr; Select/Deselect All) to deselect them.
 * 4) Select the object of interest by clicking  on it.
 * 5) Press  to center the view.

Jumping to the Camera's Viewpoint
To see the scene as the virtual camera sees it, press. Afterwards, you can rotate, pan, and zoom normally, but the virtual camera will not follow. To go back to your previous view, press again. (In the latest versions of Blender, the virtual camera can be made to follow all the changes made in viewpoint while in camera view by checking the option "Lock Camera to View" on the Transform panel. Hit on your keyboard to bring up the transform panel. To disable this option uncheck "Lock Camera to View.")

Zooming into a Selected Area
Suppose you want to get an extreme closeup of a particular area. Because there's no center mark on the viewport, you might have to pan and zoom several times to get the desired view.

The shortcut for zooming to an area is:
 * 1) Activate a 3D view window that contains the area of interest.
 * 2) Press .  A crosshair appears in the viewport.
 * 3) Click and drag with  to draw a rectangle around the area of interest.
 * 4) When you release, the viewport will zoom in on the area you selected.

View Navigation
You can also change your viewpoint in the 3D view by “walking” or “flying” through it. To activate this, press. By default in Blender 2.70, this puts you in “walk” mode. Earlier versions only offered “fly” mode. (In Blender 2.70 and later, you can choose which one you prefer in User Preferences, under the Input tab.)

In both modes, helpful prompts appear in the header of the 3D view window to remind you of the key functions while the mode is in effect. When you have reached the position and orientation you want, press or  or  to end the navigation mode and stay there, or  or  to abandon the navigation mode and be teleported immediately back to your original position and orientation. (In 2.77+, pressing will teleport you to where the cross hairs point towards.)

Walk Mode
In this mode, you move the mouse to turn your view up/down/left/right, and, , and  or the corresponding arrow keys to move forward, left, back or right, and  and  to move up or down respectively. Hold a movement key down to keep moving. Movement stops as soon as you release it. Pressing will “teleport” you close to whatever objects lie within the crosshairs at the centre of the view.

You can also use to turn on gravity. Make sure there is a floor or other object under you to land on! With gravity on, you can no longer use the vertical movement keys, but you can use to make jumps. Press again to turn gravity off.

Fly Mode
In this older mode, moving the mouse to change the view works the same as in Walk mode, but the above direction keys (,, , , , and the arrows) apply “thrust” in the respective directions, so you keep moving after releasing the key. Press the key repeatedly to increase your speed in that direction, or press the key for the opposite thrust direction to reduce your speed. You can roll the mouse wheel up to apply forward thrust, or roll it down to apply backward thrust.

Your current velocity vector automatically changes direction with you when you turn. Thus, you can apply a single burst of sideways thrust while facing an object, then, without applying any additional thrust, keep turning to face the object, and you will go right around it.

Visibility Layers
Every object in the scene is assigned to one or more of 20.

Visibility layers have many uses:
 * You can put scenery, characters, particles, and lamps in different layers, to help organize your scene.
 * By changing which layers are visible, you can simplify your view of the scene and work with only one or two layers at a time.
 * When rendering, only visible layers are included. You can use this to render your scene layer by layer, checking each layer separately.
 * You can configure lamps to illuminate only objects in the same layer.

In Object Mode, you can tell which layers are visible by looking at the twenty small boxes located in the 3D View header between the Transform Orientation menu and the "Lock" button. The top row of boxes represents layers 1 through 10, with 1 being the leftmost and 10 being the rightmost. Similarly, the bottom row of boxes represents layers 11 through 20.

Hotkeys

 * To view just one of layers 1 - 9, press ...
 * To view just layer 10, press.
 * To view just one of layers 11 - 19, press ..
 * To view just layer 20, press.
 * To toggle the visibility of one of layers 1 - 9 without affecting the visibility of the other layers, press ...
 * To toggle the visibility of layer 10 without affecting the visibility of the other layers, press.
 * To toggle the visibility of one of layers 11 .. 19 without affecting the visibility of the other layers, press ...
 * To toggle the visibility of layer 20 without affecting the visibility of the other layers, press.
 * To make all layers visible at once, press . Press again to return to your previous layer visibility setting.

On the AZERTY keyboard layout, the standard number keys are the &é"'(-è_çà keys. Do not use  unless you want to toggle visibility as explained below.

Holding down while selecting a layer (by keyboard or mouse) will, instead of making only that layer visible, toggle the visibility. In this way, you can select combinations or to hide particular layers.

The key to press to select all layers at once differs by keyboard layout. It is:
 * (the key under Esc) on UK keyboards,
 * US,
 * German, Swedish, Finnish and Hungarian,
 * Swiss German,
 * Danish,
 * AZERTY,
 * Norwegian,
 * Spanish,
 * Portuguese,
 * Brazilian Portuguese,
 * Italian, and
 * Russian.

After pressing the aforementioned key, holding down while pressing it again will restore the visibility settings you had before you made all layers visible.

When only one layer is selected, new objects are automatically assigned to that layer. When two or more layers are visible, new objects are assigned to the most recently visible layer.

Count Your Polys
If you want to count the polygons in your scene, the data is available in the Info Header.

As you can see in the above image, this scene has 507 vertices and 500 faces (polygons).
