|-
||
|| Next, let’s add hatches on this rectangle.
|-
|| '''Slide Number 6'''

'''What is a Hatch?'''
|| Cross sections of a drawing are filled with thin parallel equally spaced lines.

|-
|| Open the text file and cursor on the file text.

Close the text file.
|| Let’s open the text file and notice a 45 degree angle.

Let’s close the text file.
|-
|| Go back to '''Freecad'''.
|| Go back to '''Freecad'''.
|-
|| Select the rectangle.

Click on '''downgrade''' once to make it to wireframe mode.

|-
|| For '''scale''' type 1 and press '''Enter'''.
|| Let’s change the scale from 5 and make it to 1.
|-
|| Cursor on the rectangle.
|| Notice that more hatch lines appear in the rectangle now.
|-
||
|| Pause the video and change the spacing, line style and angle.
|-
|| Cursor on the hatched lines.
|| Practice to create various hatching styles.

Next, let’s learn about arrays.
|-
|| '''Slide Number 7'''

'''What is an Array?'''

|| '''Array''' is specified number copies of an object placed in a pre-defined order

They can be placed along a line, row-wise, column wise, circular and so on.
|-
|| Click on the the non-hatched rectangle.
|| I will select the non-hatched rectangle.
|-
|| Click on the array tool in the modification panel.

Choose the first option called '''array'''.
|| Then click on the array tool in the modification panel.

Notice several types and i will choose the first option called '''array'''.
|-
|| Cursor on the left panel.
|| The left panel properties change and it is for a '''rectangular array'''.
|-
|| For '''number of elements in x, y and z''', type 5 each.
|| For the number of elements in x, y and z, I will enter 5 each as seen.
|-
|| Type 10 for '''X interval''', and press '''Enter'''.

Do same for '''y interval '''and''' z interval''',
|| For the '''X interval''', I will type 10 and press the '''Enter '''key.

Repeat this for y and z interval values as well.
|-
|| Scroll to the top of the left panel and click on '''Ok'''.
|| Scroll to the top of the left panel and click on '''Ok''' to see the created '''array'''.
|-
|| Cursor on the canvas.
|| Learners can pause the video.

Change the values in the number of elements and intervals.

Familiarize with the various patterns that you can obtain through the arrays.
|-
||
|| Next let’s learn about '''polar array'''.
|-
|| Create a circle on the canvas with 25 mm radius.
|| First create a circle on the canvas with 25 mm radius as seen.
|-
|| Draw a line to represent the radius.

(Circle snap center on)
|| Then, draw a line to represent the radius.

It is from the center to the circumference which is called endpoint.
|-
|| Select this line and go to the '''array tool'''.
|| Select this line and go to the '''array tool'''.
|-
|| Choose the '''Polar array''' option.
|| This time choose the '''Polar array''' option.
|-
|| Cursor on the left panel.

Type 12 for '''Number of elements'''.

|| Again, the options in the left panel changes.

Type 12 for '''Number of elements'''. Do not press the '''Enter''' key.
|-
|| Move the cursor to the circumference of the circle to locate the center of the circle.
|| Move the cursor to the circumference of the circle to locate the center of the circle.

We can see a white dot at the center as seen on the screen.
|-
|| Click on it and notice that the circle is equally divided into 12 sections.
|| Click on it and notice that the circle is equally divided into 12 sections.
|-
|| Select the circle and the '''circular array.'''
|| Next select the circle and the '''circular array''' on the canvas.
|-
|| Click on the '''array tool''' and select the '''circular array''' option.
|| Click on the '''array tool''' and select the '''circular array''' option.
|-
|| Cursor on the left panel.
|| On the left panel several properties array.
|-
|| Cursor on the various options.
|| Radial distance, tangential distance, Number of circular layers and symmetry can be changed.
|-
|| Type 100 for radial distance.

Type 50 for tangential distance.

Type 3 for circular layer.
|| I will change it to 100, 50 and to 3 layers.

I will keep symmetry to 1.
|-
|| Click on '''Ok'''.

Cursor on the new pattern.
|| Click on '''Ok'''.

To notice the new pattern, you may need to zoom out on the screen,
|-
|| Cursor on the canvas.
|| Learners can pause the video.

Change these values and familiarize yourself with the various patterns you can create.
|-
||
|| Next we will create a '''path array'''.
|-
|| Select the circle and then the non-hatched rectangle.
|| I will select 2 objects from the canvas.

Hold down the '''control key''' when selecting more than one object.

First I will select the circle and then the non-hatched rectangle.
|-
|| Go to the '''array tool''' and choose the '''path array'''.
|| Then, go to the '''array tool''' and choose the '''path array'''.
|-
||
|| I will leave the default options as is.
|-
|| Cursor on the movement.
|| Notice that the circle which was selected first moved towards the rectangle.
|-
|| Scroll down the '''property tab''' in the left panel to '''counts'''.

Type 10 for counts.

Cursor on the canvas.
|| Scroll down the '''property tab''' in the left panel to '''counts'''.

Change '''counts''' to 10. Notice the difference on the screen.
|-
||
|| Save your work if desired and exit '''FreeCAD'''.
