C06- Modeling- Rubick’s cube

Have you checked and used the shortcuts that we discussed in the last post?

Q: Yes, after a few tries I understood it. I felt Blender getting easier to use. What do we learn next?

Let us work on a small model now. We will create a Rubik’s Cube, we are going to need it for our film as well.

Q: I think that if we copy the default cube from Blender in 3 x 3 x 3 formation, then it will form a Rubik’s Cube, right?

Thats right! you already know the way. Now it will be easy for you to make the next model. We will now see a new tool, it is called a ‘modifier’. Like the name suggests, Modifiers are used to modify the object in various ways.

Q: OK, could you explain this a little more, so that I can understand it better?

Instead of explaining, lets make use of one of the modifiers right now so that you will get an idea. Then we can discuss about the modifiers in details.

We will use these modifiers from a very special section of Blender. It is located on the right of the 3D view below the Outliner. This section is called a ‘Property Panel’, we had discussed about it before. This panel consists of several small sub-sections. We will directly take a look at the Modifier section. We give a modifier to our default cube in Blender.

Select the cube and goto the Modifiers tab in the Property panel. This section is the Modifier section or Modifier panel. First you will see the name written as ‘Cube’, then you will find a button labeled ‘Add Modifier’. Click on this button and you will find 4 long lists. Without going any deep into the subject, we will straight away go to the second list, titled ‘Generate’. Here you can find the name ‘Bevel’ on the second number in the list. Click on it.

This will cause the list to disappear and different options for bevel will be displayed. Also if you see the edge of the cube closely you will find it to appear differently.

Q: Yes, the edges appear to have flattened out. Like they have been made blunt.

This is called ‘Bevelling’ and this is the function of the bevel modifier. There are many such modifiers present, each having a lot of options. For this part we will not discuss about them. We will just look into how to make the Rubik’s Cube.

Now if we duplicate the bevelled cube and place the copies properly then we will get the Rubik’s Cube. We had previously seen how to Duplicate, Move and Rotate an object team project management tools.

Q: Yes, ‘G’ for move, ‘R’ for rotate and ‘S’ for scale, To move in a particular axis, press X, Y or Z and press ‘Shift + D’ to duplicate!

Wow, you already have it byhearted. Now the next step is to type in a number that says how many units object is to be moved after typing X, Y, Z. So, for example, we want to move object in X axis by 5 m, then type as follows
G  X  5

for moving in opposite direction type
G  X  -5

Our cube is of 2 m, this can be confirmed in the N panel’s Dimension section. This mean that we will need to move its copy by 2 m after duplicating. We will start by moving it in the Y direction.

To make the first copy, press ‘Shift+D’ when the cube is selected. This will create the copy and move tool will be enabled. We need to move it 2 m in Y-axis, so type ‘ Y 2 ‘. You will get a copy of the cube at its side.

To make another copy, select the first cube again right click on it.

We will copy it to the left like before.

‘Shift+D , Y  -2’

We now have our first 3 copies ready. If we select the 3 object together and copy them, then our work will speed up. Use ‘Shift + right click’ to select them together and duplicate them in the X-axis.

Q: shift+D X 2, right?

Right! And -2 for the back side.

Thus we have our 9 base cubes ready, now we just have to shift select and duplicate them, that it!

Q: Now up means Z axis. It means ‘shift+D Z 2’

CS3D-C06D-Copy-Z

Yes, our Rubik’s cube is ready! Check it from all sides.

Q: Cool! it looks really good after using the bevel modifier. I am very excited to know what all is still there ahead.

Next time going ahead we will learn some new method of modelling..So lets meet next time..
