Show Slide

System Requirements Ubuntu Linux version 10.04 LibreOffice Suite version 3.3.4

Here we are using
  • Ubuntu Linux version 10.04
    as our operating system and
  • LibreOffice Suite version 3.3.4
Show Slide 4
Object 		Let’s create a geometry chart which shows a 2D shape and

equivalent 3D form.


For example,

  • a square is a 2D object
  • a cube is its 3D form
Switch to a Draw file named as
3DObjectsChart. 		We have a new Draw file here named as 3DObjectsChart.
Before we begin the drawing, let’s enable the grids and the guidelines.


We have learnt about this in previous tutorials.

Click on View >> Grid >> Display Grid

Click on View >> Guides >> Display Guides.

From the Main menu, click on View, select Grid and Display Grid.


Then again click on View, select Guides and Display Guides.

Point to the Ruler I want to set both the rulers to centimeters.
Place the mouse pointer >> horizontal ruler. Right-click >> Select Centimeters. Place the mouse pointer on the horizontal ruler.

Now right-click and select Centimeter.

Place the mouse pointer >> vertical ruler.

Right-click >> Select Centimeters.

Place the mouse pointer on the vertical ruler.

Again, right-click and select Centimeter.

Draw the box as shown in Figure 1.

<<Please ensure all the objects are placed within the margin. Or they will get cut when printing.>>

Let us now draw a text box on the top of the page.
Enter the text
Geometric Shapes in 2D and 3D inside it. 		Let’s insert the text "Geometric shapes in 2D and 3D" inside it.
Let us now divide the page into two vertical halves using a snap line.
Click >> vertical ruler and drag it to the Draw page. Click on the vertical ruler and drag it to the Draw page.


A vertical dotted line appears.

Place the dotted line on the page
Point the page is divided two halves. 		Place the dotted line on the page such that the page is divided into two halves.
Insert a text box on the left side

Type >> 2D Shapes inside it.

Let’s insert a text box on the left side and type 2D Shapes inside it.
Insert a text box on the right side

Type >> 3D Shapes inside it.

Let’s draw another text box on the right side and type 3D Shapes inside it.
Let us enable the 3D toolbars.
From the Main menu >> click on View >> select Toolbars >> select 3D-Objects. From the Main menu, click on View, select Toolbars and 3D-Objects.
Click on View >> Select Toolbars >> 3D-settings. Again click on View, select Toolbars and 3D-settings.
Point to the respective boxes The 3D-Objects and 3D-Settings tool boxes are displayed.
We will first draw the 2D shapes.
Draw a rectangle, a square,
a circle and a triangle
one below the other as shown in
slide 4.

<Pause>

We will draw a rectangle, a square, a circle and a triangle.


And place them one below the other.

Show Slide 5

Create 3D objects by Extrusion

The method of obtaining a 3D object using a 2D object is called Extrusion.


Basically, the surface is moved outward, to create the 3D object.

Select rectangle >> color it Turquoise 1 First, let us change the colour of the rectangle to Turquoise 1
Use the CTRL+C keys and create a copy of the rectangle. Press the CTRL+V keys to paste it.

Let’s make a copy of the rectangle.

Drag the copied rectangle and
place it on right half of the page. 		Let’s drag the copied rectangle and place it on right half of the page.
Select the copied rectangle and

right-click to view the context menu.

Now, while it is still selected, right-click to view the context menu.
Click on Convert >> Select To 3D Now click on Convert and select To 3D.
The 2D rectangle is converted to a cuboid.
Double click on the box rectangle and
Type the name as Rectangle

<Pause>

Let’s type “Rectangle” inside the rectangle shape.
Double click on the right side 3D rectangle box However, we cannot type text inside 3D objects.
To type text, we need to use the Text tool.
Click on the Text tool >>
Draw a text box inside the Cuboid 		Click on the Text tool and draw a Text box inside the cuboid.
Type the text Cuboid inside it. Type the text "Cuboid" inside it.
Select the text box and the Cuboid.

right click and click on Group

The Text box and the cuboid are treated as two separate objects.


Therefore, let’s group them.

Select the Square >> colour Turquoise 1 >> right click >> select 3D objects

Select the Circle >> >> colour Turquoise 1 >> right click >> select 3D objects
Select the Triangle >> >> colour Turquoise 1 >> right click >> select 3D objects

Similarly, we can colour and convert the Square, Circle and Triangle into 3D objects.


<<Pause>>

We have used extrusion to create a chart of 2D and 3D figures.
Show Slide 6

Assignment Add a new page to your Draw file. Draw a square and type the text Square. Convert the square with text to 3D. Compare with the text from the 2D square text Hint: Use the 3D Settings toolbar to create 3D objects

Pause this tutorial and do this assignment.
  • Add a new page to your Draw file.
  • Draw a square and type the text Square.
  • Convert the square with text to 3D.
  • Compare with the text from the 2D square text
  • Hint: Use the 3D Settings toolbar to create 3D objects.
Switch to the Draw file

Point to the 3D-Objects toolbar

Draw also provides ready-made 3D shapes.

You can insert these shapes using the 3D Objects toolbar.

On the left side page right click and select >> New page Let’s insert a New page in our Draw file.
Select Shell in 3D-Objects toolbar Let’s select a shape from the 3D-Objects toolbar, say Shell.
Move the mouse to the page and drag it on the page. Then draw it on the page.
Draw also allows you to create 3D objects using body rotation on 2D objects.
Select the circle on the drawing toolbar

and drag to Draw a circle

Let’s draw a 2D shape, say a circle on our Draw page.
Right-click >> select Convert >>
choose To 3D Rotation Object 		Right-click for the context menu and select Convert.


Then choose To 3D Rotation Object.

Point to the 3D object. Observe what happens to the circle.

Go to the drawing toolbar and point to the Fontwork Gallery icon >> then click on it. Click on the Fontwork Gallery icon on the Drawing toolbar at the bottom.
Select Favorite 16 >> click on OK. Let us select Favorite 16 and click on the OK button.
Point to the text Fontwork The text "Fontwork" is displayed on our Draw page.
Re-size this text for demo (enlarge it) We can re-size this text as required.
Point to the text Fontwork Now, we may want some other text in its place. How do we do that?
Double-click inside the text Fontwork Simply double-click inside the text "Fontwork"
Now you will be able to see the word "Fontwork" in black colour within the larger text.
Select this text and type Spoken Tutorials Select this text and type "Spoken Tutorials".

click anywhere on the Draw page

Now click anywhere on the Draw page.

  • Angle = 0 degrees
Let us enter the following values -
  • Number of copies = 10

Under Placement

  • X Axis = .10
  • Y Axis = .20
  • Angle = 0 degrees
Point to Enlargement

Width = .20 Height = .30 Start color = Yellow End color = Red

We will keep the Enlargement Width and Height as default

We will change the Start color to Yellow End color to Red

Click OK. Click OK.
Point to the special effects. Look at the great special effects that we got!
Point to the angles and other options as per the narration. You can get many more effects by changing the angles and the other values.
