Time Narration
00:01 Welcome to the Spoken Tutorial on 3D Objects in LibreOffice Draw.
00:05 In this tutorial, you will learn how to create 3D objects using the following options:

Extrusion 3D Toolbar 3D Rotation Object.

00:16 You will learn to edit and apply 3D effects to objects and create special effects using Duplication.
00:24 To use this tutorial, you must be familiar with Basic and Intermediate level tutorials in Draw.
00:30 Here, we are using: Ubuntu Linux version 10.04 as our operating system and LibreOffice Suite version 3.3.4.
00:40 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.
00:53 We have a new Draw file here, named as "3DObjectsChart".
00:59 Before we begin the drawing, let’s enable the grids and the guide lines. We have learnt about this in previous tutorials.
01:08 From the Main menu, click on View, select Grid and Display Grid.
01:17 Then again click on View, select Guides and Display Guides.
01:23 I want to set both the rulers to centimeters.
01:29 Place the mouse pointer on the horizontal ruler. Now, right-click and select Centimeter.
01:38 Place the mouse pointer on the vertical ruler. Again, right-click and select Centimeter.
01:45 Let us now draw a text-box on the top of the page.
01:49 Let’s insert the text: "Geometric shapes in 2D and 3D", inside it.
01:55 Let us now divide the page into two vertical halves using a snap line.
02:01 Click on the vertical ruler and drag it to the Draw page.
02:05 A vertical dotted line appears.
02:08 Place the dotted line on the page such that the page is divided into two halves.
02:14 Let’s insert a text-box on the left side and type "2D Shapes" inside it.
02:23 Let’s draw another text-box on the right side and type "3D Shapes" inside it.
02:30 Let us enable the 3D toolbars.
02:33 From the Main menu, click on View, select Toolbars and 3D-Objects.
02:43 Again, click on View, select Toolbars and 3D-settings.
02:53 The 3D-Objects and 3D-Settings tool-boxes are displayed.
03:02 We will first draw the 2D shapes.
03:05 We will draw a rectangle, a square, a circle and a triangle and place them one below the other.
03:14 The method of obtaining a 3D object, using a 2D object is called Extrusion.
03:19 Basically, the surface is moved outward to create the 3D object.
03:25 First, let us change the colour of the rectangle to "Turquoise 1".
03:31 Let’s make a copy of the rectangle.
03:35 Let’s drag the copied rectangle and place it on right half of the page.
03:40 Now, while it is still selected, right-click to view the context menu.
03:45 Now, click on Convert and select To 3D.
03:48 The 2D rectangle is converted to a cuboid.
03:52 Let’s type "Rectangle" inside the rectangle shape.
03:55 However, we cannot type text inside 3D objects.
04:00 To type text, we need to use the Text tool.
04:04 Click on the Text tool and draw a text-box inside the cuboid.
04:10 Type the text "Cuboid"' inside it.
04:14 The text-box and the cuboid are treated as two separate objects. Therefore, let’s group them.
04:21 Similarly, we can colour and convert the square, circle and triangle into 3D objects.
04:30 We have used extrusion to create a chart of 2D and 3D figures.
04:36 Pause this tutorial and do this assignment.
04:40 Add a new page to your Draw file.
04:42 Draw a square and type the text "Square".
04:46 Convert the square with text to 3D.
04:49 Compare with the text from the 2D square text.
04:53 Hint: Use the 3D Settings toolbar to create 3D objects.
04:58 Draw also provides ready-made 3D shapes.
05:01 You can insert these shapes using the 3D Objects toolbar.
05:09 Let’s insert a new page in our Draw file.
05:13 Let’s select a shape from the 3D-Objects toolbar, say Shell.
05:18 Then draw it on the page.
05:24 Draw also allows you to create 3D objects using body rotation on 2D objects.
05:33 Let’s draw a 2D shape, say a circle, on our Draw page.
05:39 Right-click for the context menu and select Convert. Then choose To 3D Rotation Object.
05:47 Observe what happens to the circle. It is now a 3D object.
05:54 Click on the Fontwork Gallery icon on the Drawing toolbar at the bottom.
05:59 Let us select Favorite 16 and click on the OK button.
06:04 The text Fontwork is displayed on our Draw page.
06:09 We can re-size this text as required.
06:12 Now, we may want some other text in its place. How do we do that?
06:17 Simply double-click inside the text "Fontwork".
06:21 Now, you will be able to see the word Fontwork in black colour within the larger text.
06:26 Select this text and type "Spoken Tutorials".
06:30 Now, click anywhere on the Draw page.
06:33 The words "Spoken Tutorials" will now be displayed on the page.
06:36 Next, let us learn how to apply effects on 3D objects.
06:41 Let us apply effects to a spherical shape.
06:44 So, let us select it and right-click for the context menu. Now select 3D Effects.
06:51 You can see various options here.
06:57 For demo purpose, let us change Depth parameter to 3cm.
07:05 Under Segments, let us change Horizontal to 12.
07:10 Under Normal, let us select Flat option.
07:14 Observe the appearance of the object in its preview window.
07:19 Now, click on the Assign icon at the top right-hand corner of the dialog-box.
07:26 Next, click on the X mark at the top left-hand corner to exit the dialog-box.
07:32 Observe our shape now. The effects we selected have been applied to it.
07:38 Here is an assignment for you. Create a similar picture like the one shown on the slide.
07:45 Use the 3D Effects dialog-box to achieve this.
07:49 You can also create special effects using Duplication with 2D and 3D objects.
07:55 Let’s create a new page and draw a rectangle in it.
08:00 Let us create an effect using Duplication on the 2D rectangle.
08:04 From the Main menu, select Edit and click Duplicate.
08:09 The Duplicate dialog-box appears.
08:12 Let us enter the following values - Number of copies = 10
08:18 Under Placement, X Axis = 10
08:26 Y Axis = 20
08:30 Angle = 0 degrees.
08:34 We will keep the Enlargement Width and Height as default.
08:44 We will change the Start color to Yellow, End color to Red.
08:57 Click OK,Look at the great special effects that we have got!
09:04 You can get many more effects by changing the angles and the other values.
09:09 This brings us to the end of this tutorial.
09:12 In this tutorial, we have learnt how to create 3D objects using the following options:

Extrusion 3D toolbar 3D Rotation Object.

09:23 We have learnt to edit 3D objects and apply 3D effects to objects.
09:27 We also learnt to create special effects using Duplication'.
