|-
||Open '''FreeCAD''' and go to Draft workbench.
|| Open FreeCAD and start a new file.

Select Draft workbench.

Make sure that Orthographic and top view are selected.
|-
||Cursor on the polygon tool.
|| Let’s add a pentagon to this drawing.

'''FreeCAD''' inscribes a '''polygon''' inside of a circle.
|-
||'''Slide Number'''

'''Inscribing pentagon inside a circle'''

For inscribing pentagon on a circle

R=0.85 A

A is length of the side of the pentagon

R is the radius of the circle
|| Equation for inscribing a '''pentagon''' of a circle is '''R '''is equal to''' 0.85 times A'''.

Where '''A''' is the length of the side of the '''pentagon'''.

And''' R''' is the radius of the circle.
|-
||Click on the '''polygon tool '''in the '''Draft creation tools '''menu.
|| Click on the '''polygon''' tool as seen.
|-
||Cursor on '''Sides''' option in '''Combo view''', '''Model''' tab.

Change the number of '''Sides''' to 5.
|| Notice the '''Sides''' option in '''Combo view''', '''Model''' tab.

Change it to 5, since a pentagon has 5 sides.
|-
||Move the cursor to the drawing canvas.
|| Move the cursor to the drawing canvas and notice the + crosshair.
|-
||Left click hold and drag.
|| Left click hold and drag to form the desired polygon.

First only the circle on which the polygon is inscribed is seen.
|-
||Annotation on the Radius panel.

Highlight the radius change in the comboview panel.

|| Notice the '''Radius''' form on the left '''combo View''' panel.

As you drag to form a larger circle, the '''radius''' in the form also changes.
|-
||At ~ r=20, left click on the canvas.
|| I will keep the radius around 20mm and click on the canvas.

This fixes the radius of the circle and the polygon can be seen.

|-
||Cursor on the polygon.

Highlight the green outline on the selected object at editing.
||

To select an object click on it and notice the green outline.
|-
||Highlight polygon while editing.
|| The new object is also added in the '''combo view''' as polygon.
|-
||Click on polygon to select it.

|| Make sure the polygon is selected in the combo view.

|-
||Highlight in video editing.

Cursor on Property in Model tab.

Place the cursor on the edge of the panel.

A two sided arrow appears on the edge.

Click and drag to resize the panel.

Highlight in video editing.

|| Place the cursor on the edge of the panel as seen.

Click and drag to resize the panel.

Properties of the object can be changed using the '''Model''' tab.
|-
||For Bounding box, choose true.

Show the green bounding box.
|| For the first option of the '''bounding box''', choose '''true'''.

Notice that a bounding box for the object is displayed.
|-
||Cursor near the bounding box.
|| This allows us to encompass the area of selected objects in the canvas.
|-
||Toggle the bounding box off from the view menu.
|| We can also toggle this on or off from the view toolbar on the top menu.
|-
||Scroll down to '''object style'''.

Open the pull down menu for '''Display mode'''.(Draw style)

Select Wireframe for Display mode.
|| Scroll down to '''object style'''.

Click on the pull down menu for '''Display mode''' as seen here.

|| I will choose '''Flat lines''' now.

This will enable us to draw a color shaded or color filled object.
|-
||Click on the form for '''line color'''.
|| Scroll down and click on the form for '''line color'''.

A '''Select color''' dialog box appears.

Some of you will have to click again for the dialog box to open.
|-
||Choose red and click on '''Ok'''.
|| I will choose red and click on '''OK'''.

|-
||Cursor on circle tool in Draft tools.
|| Now, pause the video, and draw a circle partially overlapping the pentagon.
|-
||Cursor on '''flat lines''' and show filled '''pentagon'''.
|| Use '''flat lines''' for '''display mode''' and fill it with a color of your choice.
|-
||Cursor on '''transparency'''.
|| Then change the '''transparency''' level and notice the changes.
|-
||Left click on the canvas and notice the changes.
|| The color changes will be visible only when the object is not highlighted.
|-
||Click on one of the edges of the pentagon.
|| Next, let’s measure the distance of the side of the '''pentagon'''.

First click to select the edge of your choice.
|-
||Click on the '''Dimension tool '''on the '''Draft Annotation tools'''.
|| Next, click on the '''Dimension tool '''in the '''Draft Annotation tools'''.
|-
||Move the line a bit away from the selected line.
|| A line parallel to the selected line appears on the canvas.

Place it a bit away where you want the annotation to be placed.
|-
||Left click and notice the measured distance.
|| Left click to notice the measured line and annotation.

For some of you the font size may be very small and not visible.
|-
||
|| We can format the annotation globally or individually.
|-
||Select the '''Dimension''' label in the '''comboview''', '''model''' tab.
|| In the '''combo View''', '''model''' tab, Select the '''dimension''' label.
|-
||Open the '''line color''' selection dialog box in the '''graphics''' section.

|-
||Cursor on the text properties.
|| Set the desired parameters here for global setting.

The changes will apply only to the annotations that you will add later on.
|-
||Click on '''Cancel'''.
|| For now I will click on '''Cancel''' as I do not want to change them.
|-
||click on the '''measure distance''' tool on the '''View toolbar'''.
|| Let us measure the distance between two user chosen points.

First click on the '''measure distance''' tool on the '''View toolbar'''.
|-
||Cursor on the report view window.
|| The report view window prompts the user to pick the first point.
|-
||Click on a point on the canvas.
|| Click on your desired first point.

I will choose one of the vertex of the pentagon.
|-
||Click on another vertex.
|| Then I will click on another vertex.

Notice the distance between them is now shown on the canvas.
|-
|| Cursor on '''combo view''', '''model tab''' and show the added measurement.
|| Delete the measurements using the '''combo view''', '''model''' tab.

Select the object and delete it.
|-
