C05- Modeling revision and shortcuts

In blender or in any other 3D software, while modelling or doing any other work, it is very important to check the 3D view from all sides. Lets say that you are working on a model or an animation, if you work in just one view or in one angle you will make many mistakes and your work will have many defects. Even while drawing if we turn the page upside down, we can identify many mistakes easily. The same logic is applicable here, checking the model from various angels allows us different perspectives to check it. You should make a habit of checking the model from different angels in 3D view. Keyboard and mouse are very useful for such things, they help us improve our speed and work. We have already seen some of the tools used here. In this post we will revise the important tools again. Moreover, we will also learn some new tools. This will make using blender a lot more easy for you.

Whats next, lets see how to navigate in 3D view.
Rotating the 3D view is called ‘Orbitting’ (to Orbit) in Blender. To orbit is to rotate around a fixed point. First bring your mouse into the 3D view, then press and move the middle mouse button, i.e. middle click and drag. This shortcut can be written as:
3D view orbit: middle click drag
I will write the next short cuts in the same way.

To move the view close or far is called ‘zooming’ (to zoom). You must have heard about it while using a camera. To zoom, use the scroll wheel of the mouse. You will see the object near or far away.
3D view zoom: scroll wheel.

If you want to move the viewport up/down or left/right, the action is called ‘Panning’ (to pan). We need to use both the keyboard and the mouse to Pan. Hold ‘Shift’ key on keyboard and press and drag the middle mouse button.
3D view pan: Shift + middle click drag

You will now be able to orbit, zoom and pan as shown below.

CS3D-C05A-Orbit-Zoom-Pan

While working on a model, if you press the ‘Z’ key on the key board, you will go into the wireframe mode. This means that your model will become see through, i.e. only edges are visible. Press the ‘Z’ key again to go to solid view or shaded view.

CS3D-C05K-Wireframe

There are a few shortcuts in blender to view the object from exactly front, back or sides. The number pad on the right side of the key board is used effectively for this purpose.

CS3D-C05L-numpad

Key 1,3 and 7 on the numpad are used to switch to front, right and top view respectively. Its easy to remember also. Key 7 is on the top side of numpad, so it is for Top View, Key 3 is on right so it is for Right Side View and key 1 is for Front View. Again, if use use ‘Control’ Key with Keys 1, 3, 7 we will get the exact opposite view. Key 7 is for Top view so for bottom view we can use control + 7.
Top view: 7
Front view: 1
Right view: 3
Bottom view: Control + 7
Back view: Control + 1
Left view: Control + 3

CS3D-C05J-Views

Going ahead, to select any object in the view port, we must right click on it.
Select object: Right click (on object)

Once an object is selected we can move it, rotate it or scale it to any size.
To move or grab the object, press the ‘G’ key when in view port and then move the mouse, the object will move in the direction of the mouse.
Object move: G

CS3D-C05B-Move

Similarly you can rotate the object using the ‘R’ key.
Object rotate: R

CS3D-C05C-Rotate

For scaling use ‘S’ key.
Object scale: S

CS3D-C05D-Scale

While moving, if you want to move the object in x, y or z axis then after pressing the ‘G’ key you can press the x, y, or z keys to move the object along that direction.
Object move: G X or G Y or G Z

CS3D-C05E-Move

This technique is applicable to rotate and scale as well. After R key is pressed for rotate or S key is pressed for scale we can select a particular axis using the X, Y and Z keys.

Object rotate: R X or R Y or R Z

CS3D-C05F-Rotate-with-Y

Object scale: S X or S Y or S Z

CS3D-C05G-Scale-Z

Next is how to create a copy of an object. For this we first need to select the object that we want to copy, later press the key ‘Shift + D key’. This creates a duplicate copy of the object and move mode gets turned on. We can then move the newly created object. Here too we can move the object in a specific axis X, Y or Z.
Object Duplicate: Shift + D

CS3D-C05H-Random Copy

We have seen that to select any object we can right click on it. We use ‘Shift + Right Click’ to select multiple objects. This enables us to move or rotate multiple objects a the same time. Again to select or deselect all objects in the viewport, we use the key ‘A’. This is a ‘toggle’ between select and deselect all objects.
Select more objects: Shift + Right click
Select all objects / Deselect all objects: A (toggle)

CS3D-C05I-Selection
