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'.
