Blender is free and open source software of 3D graphic for modeling, rendering and compositing applicable in different fields: from architectural modeling to videoanimation. The authors of the software permit studying and developing the software to enhance its features, so there are several add-ons scripted by a large and active community of software developpers available on line. Also, on the web you can easily find several forums, chats and youtube channels to find support and solutions to bugs or general issues.
- Object Mode to apply transformation to single object
- Edit Mode to apply transformation to elements composing the object.
you can switch from one mode to another by pressing TAB on the keyboard or selecting mode on the bottom window.
The scene can be completely customized: you can chose the type of area of each window by selecting button highlighted in blue on the image. There are preset scene (highlighted in orange on image) with viewport and window organization suitable for different functionality: compositing, animation, motion tracking etc..
Up to version 2.3 all commands were performed only by typing on keyboard, this gave the software a hard-to-use reputation. The latest version has more complete interface but shortcuts are still the most used way to perform commands instead of searching by through the toolbars.
HOW TO MOVE IN THE SPACE
To move on the 2d space (PAN) hold the SHIFT key while clicking mouse’s wheel
To orbit hold mouse’s wheel while moving mouse around.
To zoom in and out simply scroll the wheel.
To select an object, right click on it: in Edit Mode you’ll select vertex, edges or faces depending on settings; in Object Mode you’ll select the entire object. When an element is selected, you can press A to release the selection.
To create a rectangular selection, type B key while holding down left click of the mouse to define the rectangle of selection. Press Alt and B key to deselect objects by dragging rectangle around them.
Type A to select all elements on the scene and A again to deselect.
Here are the shortcuts for main commands:
G to grab
R to rotate
S to scale
E to extrude
SHIFT D to duplicate
these commands can be combined with global coordinates x,y and z to constrain transformations along an axis.
RX, RY, RZ
SX, SY, SZ ….
If I want to constrain these transformations along local axis of the object, you should type
GXX, GYY, GZZ
RXX, RYY, RZZ
SXX, SYY, SZZ ….
