Blender 3d – introduction to UI 2.6x

The interface! The hard part.

Default cube

Default lamp

Default camera

dragable

Change content of window


2

Shortcuts – important! Use 3 button wheel mouse and press-click the wheel to rotate view

Scroll wheel to zoom

Shift click wheel to pan

(gestures on mac: swipe two fingers on pad to pan, zoom on pad to zoom, alt+two-finger-swipe to

rotate view)

Two modes. Edit mode and object mod (tab)

The dashed red/white cursor is a 3d pointer. If you add a new object it will be placed where the

cursor is.

Add new objects (shift + A)

Selection (left OR right mouse button) – configure under file/user preferences input tab

select with ’Left’ or ‘Right’

Shift click for selecting more objects

Select many vertices with b (for border)

Object mode or edit mode Shading preview

Editing mode

Select point(vertex), edge or face

Move, rotate or scale


3

Press A for selecting All or nothing

Grab (and move): G

Rotate and scale (R and S)

Extrude (E)

Press X, Y or Z for constraining direction

Views

View menu

Tool shelf

Views + shortcuts

Four window view


4

Modes and view

Tree view of objects

materials

The object data

The object

modifiers

rendering

”world” -

background


5

New objects

Shift + A or menu Add

Agenda

Modeling practice

Create Primitives ( place 3d cursor and shift + A)

Extrude objects (select object > tab> select faces – click on face > press E and drag)

Remember to go OUT of edit mode (tab again) before creating new object!!

Create a COLUMN

1. Add cylinder

2. Tab to go in edit mode

3. Select extrude, scale – be creative!


6

Smoothing and modeling:

Showing smooth rendering in viewport:

A little more advanced modeling:

Making more smooth objects with Subdivide

Default flat

Smoot shading

Subdivide selected faces


7

Modifiers Subdivision modifier

Modifier mode

Add modifier

bring up this

menu


8

Modeling a logo

Press shift + A and add a text object

Go into edit mode with tab

Write your name (for instance)

Go into object data (on the right – find the F icon)

Experiment with extrude and bevel

(extra - change the font)

Texturing

No material is present by default. Click new to add new material


9

Change diffuse color, intensity and hardness to create a standard colored material. Do name your material!

Rendering Render the image – your render will always be through the default camera.

Add new camera. Change the perspective view to how you want your image. Press crtl alt num-0 to change the

view of the selected camera to the perspective view. Render.


10

Modeling a Wing Place a graphic in the background

Open the property box by pressing n. Find the background image property and locate the background drawing

in your filesystem

There are basically two different ways to model the wing. 1. Box modeling – the easiest way. 2. Curve modeling

– a little bit more difficult because you need to be able to handle the curve tool.

Boxmodelling Create a plane and go into vertex mode (tab). Places points in the left part of the wing like this:


11

To make the box transparent, change the viewport to wireframe with this icon at the bottom:

Select the two rightmost points and press e for extrude:

Move the next two points into place and repeat until the entire wing is done.

It might look a little rough at first:


12

But you can refine by adding extra faces with loop cut (crtl + r)

Refine more for a smooth result.

Select all and press e for extrude.


13

Curves

Create a curve in the topview port by adding a new curve and create new points:

Curves: shift + Aad Bezier curve tab G (for move point)+ click to place it click handle point + G to

move handle e (to add extra point at the end) r for rotate and s for scale handles.

To be sure that you are working with 2d curves press 2d ind the object data panel:


14

To close curve: find the cyclic property in the objectdata box and check it.:

Each point may be changed by pressing v (change vertex type).

The curve may now be extruded with e or use the extrude and bevel in the object data panel under geometry


15

A FEW SHORTCUTS overview

Shift + A –add new objects

select all / select nothing A, select with border B

free move: G

rotate R

scale S

undo: crtl Z

zoom: scroll wheel

rotate view: scroll wheel push

e: extrude

del or X: deletes

n: precise transform properties

t: objects tools

knife tool: k + enter

save interface: crtl u

crtl + r: loop cut

f: fill gaps with face

v: change vertex type

crtl num-0: change camera to active (emulate num-pad in prefs)

crtl alt num-0: change active camera to viewport (emulate num-pad in prefs)

crtl + u: save configuration (window settings, screen elements etc included)

Where to go from here? At blender.org numerous help tools is available. It is a very active community.

http://www.blender.org/education-help/tutorials/getting-started/

Be aware that the latest official version of blender - version 2.49 is very different from 2.5x and newer.

So you might get a hard time to avoid old tutorials – be sure to check that tutorials and recommended short-

cuts are for 2.5x or newer.

Watch the movie Sintel and dream about your future skills.

Do practice alot and do work very hard! – the only way in 3d.
