Revision as of 12:25, 11 December 2015

Time Narration
00:00 Welcome to the spoken tutorial on feedback diagram creation using Xfig.
00:07 In the spoken tutorial on block diagram creation, wWe created the diagram shown here.
00:14 We will refer to it as the blocks tutorial.
00:18 Please master the blocks tutorial before starting the current one.
00:22 In this tutorial, we will explain how to create block diagrams of the type shown on this page.
00:31 I shall use Xfig version 3.2, patch level 5.
00:37 We will begin with "block.fig" created in the blocks tutorial.
00:43 Let us go to Xfig.
00:47 Let us choose the file, then open.
00:52 In the entry box, we can enter block and press open. Or double-click on “block.fig”.
01:04 Using the Save as option on File, we will save this figure as "feedback".
01:24 We now have the file "feedback.fig".
01:28 Let us put the grids on by clicking on the grids.
01:34 The scroll bar on the right can be used to move the canvas up or down.
01:41 The role of each mouse button is shown on the top right hand side.
01:46 This role depends on the activity.
01:49 To illustrate this, let me take the mouse to the vertical scroll bar.
01:55 Observe the comment next to the left button.
01:59 I cannot move the mouse to show this. It is because, the role of the buttons will change if I move the cursor away from the scroll bar.
02:08 The left button moves the canvas up and the right button moves it down.
02:17 Instead of clicking the left or right button, we can also click the centre button, hold and drag the canvas up or down.
02:31 In a similar way, you can move the canvas to the right or left, using the scroll bar on the top. Left, right..
02:44 I will now move the box to the centre by clicking the middle button, holding and dragging the canvas to the centre.
02:57 As I release the mouse, the box gets moved to the centre.
03:03 Let us now create the feedback diagram starting from this block.
03:08 Let us copy this box.
03:13 Click on the box and select it.
03:16 Move the mouse to the new location and click.
03:27 Let us now put some text.
03:29 Let us click the text-box, indicated by T, from the left hand side panel.
03:37 Let us choose the size of the text.
03:43 Move the mouse to the value-box and enter 16.
03:51 Click Set.
03:53 Let us click the Text Just button in the attributes panel.
04:02 Let us choose centre alignment.
04:05 Let us click at the centre of the first box.
04:11 Sorry, I did not choose the correct position.
04:15 I will click at a different location to move the cursor away.
04:19 I will then click at the correct position.
04:27 Let us now type the text “Control” and click the mouse.
04:35 We would now want to enter some more lines with arrows.
04:40 Let us choose the POLYLINK button.
04:43 Let us select the Arrow Mode button from the attributes panel and select the second option.
04:53 Let us click the Arrow Type button and an arrow head.
05:00 Let us click at the point where we want the line to start.
05:08 Let us move the mouse to the end point of the desired line.
05:14 Let us now click there with middle mouse button.
05:20 The line is created with an arrow.
05:25 I want to place a circle.
05:27 Let us choose the circle on the left from the left hand side panel.
05:33 We will place it to the left of the first box.
05:37 Click the mouse. As I move the mouse, the circle becomes bigger.
05:47 When we get the right size, let us release the mouse button.
05:54 Oops, the circle is larger than what I wanted.
05:57 I can undo this operation, using the edit button at the top.
06:02 We can also delete this object, using the Delete button on the left hand panel.
06:10 Let us do that now.
06:14 A skeleton with cross hairs appears.
06:18 All key points of all objects also appear.
06:22 Move the cross hairs to a key point that indicates the circle and click.
06:32 In case a wrong object is deleted, no need to panic.
06:35 You can undo it: Click the Edit button, hold, go to Undo and release the mouse.
06:44 If some objects are closely placed, you may have difficulty in choosing them.
06:49 You can solve this through the zoom feature.
06:55 Click the View button on the top left hand side, hold and choose one of the zoom options.
07:00 Let me release the mouse at Zoom to fit the canvas.
07:04 Now it is easy to discriminate between the objects.
07:08 Let me delete the circle now.
07:12 Let me unzoom.
07:20 I will move the diagram to the centre with the use of scroll buttons.
07:35 I do not like to leave delete symbol on, because I can accidentally delete something else.
07:41 I can change this by choosing any other button.
07:44 Let me choose the left circle.
07:47 Let me redraw the circle.
08:00 I want to put another line from this line.
08:04 For this, we will first put a dot on the line.
08:07 Let us click the Library on the left hand side panel.
08:11 The library is indicated by a stack of books.
08:15 A dialog window opens.
08:17 Next to the Library, it says None Loaded.
08:20 Let us click and hold.
08:22 A list of available libraries appears.
08:25 Move the mouse to the Logic library and release the mouse .
08:31 Let us choose the small dot by double clicking on it.
08:36 The dialog window gets closed.
08:38 We see a cross hair along with the chosen small dot.
08:42 Let us place the dot on the line by clicking.
08:51 The cursor and the small dot show up once again, suggesting that we can place it at some other location also.
08:57 We do not want to place the dot at any other place.
09:00 Let us close it by clicking the right button of the mouse.
09:05 The right button does an undo operation.
09:08 In this case, dot selection has been removed.
09:10 Let us draw a line from this dot to the circle.
09:15 Let us select the Polyline.
09:1 Notice that the previous selections of arrow mode and arrow type have been remembered.
09:24 Within a session, Xfig remembers the parameter values.
09:28 Click at the dot.
09:34 Move the mouse to the bottom and click.
09:41 Now turn the mouse to the left, until at the bottom of the circle. Click.
09:47 Move the mouse to the circle and now click the middle mouse button.
9:54 Let us draw another line, to the left of the circle by copying.
10:08 Let us now save this figure using the File button at the top left hand corner of Xfig and choosing Save.
10:19 Let us now Export the file.
10:22 Let us click the File button once again and choose Export.
10:30 Let us choose Language and then PDF.
10:36 We get the file "feedback.pdf".
10:43 Let us open this file through the command open feedback.pdf.
10:56 We now have the block diagram that we wanted.
11:00 We have completed our objective.
11:04 We have an assignment for you.
11:08 Substitute the blocks with different objects.
11:13 Try out operations such as rotate and flip.
11:19 View the file "feedback.fig" in an editor and identify different components.
11:25 Using the library, create entirely different block diagrams.
11:32 Spoken Tutorial is a part of the Talk to a Teacher project, supported by the National Mission on Education through ICT (NMEICT), MHRD, Government of India.
