In the entry box, we can enter “block” and press open.

Or double click on “block.fig”.

|-

We now have the file feedback.fig

|-
| style="border-top:none;border-bottom:0.035cm solid #000000;border-left:0.035cm solid #000000;border-right:none;padding:0.097cm;"| Click Grid Mode

| style="border-top:none;border-bottom:0.035cm solid #000000;border-left:0.035cm solid #000000;border-right:none;padding:0.097cm;"| Scroll bar

|-
| style="border-top:none;border-bottom:0.035cm solid #000000;border-left:0.035cm solid #000000;border-right:none;padding:0.097cm;"| Top right

This role depends on the activity.

To illustrate this, let me take the mouse to the vertical “scroll bar”.

Observe the comment next to the left button.

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.

The “left button” moves the canvas up and the “right button” moves it down.

Instead of clicking the left or right button, we can also click the “centre button”, hold and drag the canvas up or down.

In a similar way, you can move the canvas to the right or left, using the “scroll bar” on the top.

I will now move the box to the centre by clicking the “middle button”, holding and dragging the canvas to the centre.

As I release the mouse, the box gets moved to the centre.

|-

|-

Click on the box and select it.

Move the mouse to the new location and click.

|-
| style="border-top:none;border-bottom:0.035cm solid #000000;border-left:0.035cm solid #000000;border-right:none;padding:0.097cm;"| Click text

Let us click the “Text box”, indicated by T, from the left hand side panel.

|-
| style="border-top:none;border-bottom:0.035cm solid #000000;border-left:0.035cm solid #000000;border-right:none;padding:0.097cm;"| Text size

Move the mouse to the value box and enter 16.

Click “Set”.

|-
| style="border-top:none;border-bottom:0.035cm solid #000000;border-left:0.035cm solid #000000;border-right:none;padding:0.097cm;"| Text just

Click

Let us choose centre alignment.

Let us click at the centre of the first box.

Sorry, I did not choose the correct position.

I will click at a different location to move the cursor away.

I will then click at the correct position.

|-
| style="border-top:none;border-bottom:0.035cm solid #000000;border-left:0.035cm solid #000000;border-right:none;padding:0.097cm;"| Enter text

|-
| style="border-top:none;border-bottom:0.035cm solid #000000;border-left:0.035cm solid #000000;border-right:none;padding:0.097cm;"|

|-
| style="border-top:none;border-bottom:0.035cm solid #000000;border-left:0.035cm solid #000000;border-right:none;padding:0.097cm;"| Polyline

|-
| style="border-top:none;border-bottom:0.035cm solid #000000;border-left:0.035cm solid #000000;border-right:none;padding:0.097cm;"| Arrow Mode

Arrow Type
| style="border-top:none;border-bottom:0.035cm solid #000000;border-left:0.035cm solid #000000;border-right:0.035cm solid #000000;padding:0.097cm;"| Let us select the “Arrow Mode” button from the attributes panel and select the second option.

Let us click the “Arrow Type” button and an arrow head.

Let us click at the point where we want the line to start.

Let us move the mouse to the end point of the desired line. Let us now click there with “middle mouse button”.

The line is created with an arrow.

|-
| style="border-top:none;border-bottom:0.035cm solid #000000;border-left:0.035cm solid #000000;border-right:none;padding:0.097cm;"| Put circle
| style="border-top:none;border-bottom:0.035cm solid #000000;border-left:0.035cm solid #000000;border-right:0.035cm solid #000000;padding:0.097cm;"| I want to place a circle.

Let us choose the “circle on the left” from the “left hand side panel”.

We will place it to the left of the first box.

Click the mouse. As I move the mouse, the circle becomes larger.

When we get the right size, let us click the mouse button.

Oops, the circle is larger than what I wanted.

|-
| style="border-top:none;border-bottom:0.035cm solid #000000;border-left:0.035cm solid #000000;border-right:none;padding:0.097cm;"| Edit

Delete
| style="border-top:none;border-bottom:0.035cm solid #000000;border-left:0.035cm solid #000000;border-right:0.035cm solid #000000;padding:0.097cm;"| I can undo this operation, using the edit button at the top.

We can also delete this object, using the Delete button on the left hand panel.

Let us do that now.

A skeleton with cross hairs appears.

All key points of all objects also appear.

Move the cross hairs to a key point that indicates the circle and click.

|-
| style="border-top:none;border-bottom:0.035cm solid #000000;border-left:0.035cm solid #000000;border-right:none;padding:0.097cm;"| Wrong delete

Zoom
| style="border-top:none;border-bottom:0.035cm solid #000000;border-left:0.035cm solid #000000;border-right:0.035cm solid #000000;padding:0.097cm;"| In case a wrong object is deleted, no need to panic.

You can undo it: Click the “edit” button, hold, go to “Undo” and release the mouse.

If some objects are closely placed, you may have difficulty in choosing them.

You can solve this through the “zoom” feature.

Click the “View” button on the top left hand side, hold and choose one of the zoom options.

Let me release the mouse at “Zoom to fit the canvas”.

Now it is easy to discriminate between the objects.

Let me delete the circle now.

Let me unzoom.

I will move the diagram to the centre with the use of scroll buttons.

I do not like to leave “delete” symbol on, because I can accidentally delete something else.

I can change this by choosing any other button.

Let me choose the left circle.

|-
| style="border-top:none;border-bottom:0.035cm solid #000000;border-left:0.035cm solid #000000;border-right:none;padding:0.097cm;"| Circle
| style="border-top:none;border-bottom:0.035cm solid #000000;border-left:0.035cm solid #000000;border-right:0.035cm solid #000000;padding:0.097cm;"| Let me redraw the circle

|-
| style="border-top:none;border-bottom:0.035cm solid #000000;border-left:0.035cm solid #000000;border-right:none;padding:0.097cm;"|

For this, we will first put a “dot” on the line.

|-
| style="border-top:none;border-bottom:0.035cm solid #000000;border-left:0.035cm solid #000000;border-right:none;padding:0.097cm;"| Library
| style="border-top:none;border-bottom:0.035cm solid #000000;border-left:0.035cm solid #000000;border-right:0.035cm solid #000000;padding:0.097cm;"| Let us click the “library” on the left hand side panel.

The library is indicated by a stack of books.

A “dialog window” opens.

Next to the library, it says “None Loaded”.

Let us click and hold.

A list of available libraries appears.

Move the mouse to the “Logic library” and release it.

|-
| style="border-top:none;border-bottom:0.035cm solid #000000;border-left:0.035cm solid #000000;border-right:none;padding:0.097cm;"| Small dot

Place dot
| style="border-top:none;border-bottom:0.035cm solid #000000;border-left:0.035cm solid #000000;border-right:0.035cm solid #000000;padding:0.097cm;"| Let us choose the “small dot” by double clicking on it.

The “dialog window” gets closed.

We see a cross hair, along with the chosen small dot.

Let us place the dot on the line by clicking.

The cursor and the small dot show up once again, suggesting that we can place it at some other location also.

We do not want to place the dot at any other place.

Let us close it by clicking the right button of the mouse.

The right button does an “undo” operation.

In this case, dot selection has been removed.

|-
| style="border-top:none;border-bottom:0.035cm solid #000000;border-left:0.035cm solid #000000;border-right:none;padding:0.097cm;"|

|-
| style="border-top:none;border-bottom:0.035cm solid #000000;border-left:0.035cm solid #000000;border-right:none;padding:0.097cm;"| Polyline

Notice that the previous selections of “arrow mode” and “arrow type” have been remembered.

Within a session, Xfig remembers the parameter values.

Click at the dot. Move the mouse to the bottom and click.

Now turn the mouse to the left, until at the bottom of the circle.

Click.

Move the mouse to the circle and now click the “middle mouse button”.

|-

|-

Let us click the “file” button once again and choose “export”.

Let us choose “language” and then “PDF”.

We get the file “feedback.pdf”.

|-
