|| Welcome to the tutorial on '''Inscribe a Polygon'''.
|-
|| 0:06
|| In this tutorial, we will learn to,
|-
|| 0:09
|| Inscribe a pentagon inside a circle
|-
|| 0:13
|| '''Format '''the object with wireframe or flatlines
|-
|| 0:18
|| Change color and line width
|-
|| 0:21
|| Add '''annotation'''
|-
|| 0:23
|| Set global or individual font size
|-
|| 0:27
|| Measure the length of an edge and
|-
|| 0:31
|| About '''View''' toolbar,
|-
|| 0:33
|| zoom and reset
|-
|| 0:35
|| To record this tutorial, I am using''' Windows''' 11 '''OS''' and '''FreeCAD''' version 0.21.1
|-
|| 0:48
|| To follow this tutorial,
|-
|| 0:50
|| Learners must be familiar with the '''FreeCAD''' interface.
|-
|| 0:55
|| For pre-requisite tutorials, please visit this site.
|-
|| 01:00
|| Open '''FreeCAD''' and start a new file.
|-
|| 01:04
|| Select Draft workbench.
|-
|| 01:07
|| Make sure that '''Orthographic''' and top view are selected.
|-
|| 01:13
|| Let’s add a pentagon to this drawing.
|-
|| 01:17
|| '''FreeCAD '''inscribes a polygon inside of a circle
|-
|| 01:22
|| Equation for inscribing a pentagon of a circle is '''R''' is equal to 0.85 times''' A'''.
|-
|| 01:31
|| Where '''A '''is the length of the side of the pentagon.
|-
|| 01:35
|| And '''R''' is the radius of the circle.
|-
|| 01:39
|| Click on the '''Polygon''' tool as seen.
|-
|| 01:41
|| Notice the '''Sides''' option in '''combo view''', '''Model tab'''.
|-
|| 01:47
|| Change it to 5, since a pentagon has 5 sides.
|-
|| 01:52
|| Move the cursor to the drawing canvas and notice the''' + crosshair.'''
|-
|| 01:58
|| Left click hold and drag to form the desired polygon.
|-
|| 02:03
|| First only the circle on which the polygon is inscribed is seen.
|-
|| 02:10
|| Notice the '''Radius''' form on the left '''combo view''' panel.
|-
|| 02:16
|| As you drag to form a larger circle, the radius in the form also changes.
|-
|| 02:22
|| I will keep the radius around 20 '''mm''' and click on the canvas.
|-
|| 02:29
|| This fixes the radius of the circle and the polygon can be seen.
|-
|| 02:34
|| To select an object click on it and notice the green outline.
|-
|| 02:39
|| The new object is also added in the '''combo view''' as polygon.
|-
|| 02:46
|| Make sure the polygon is selected in the '''combo view'''.
|-
|| 02:51
|| Place the cursor on the edge of the panel as seen.
|-
|| 02:55
|| Click and drag to resize the panel.
|-
|| 02:59
|| Properties of the object can be changed using the '''Model '''tab.
|-
|| 03:04
|| For the first option of the '''bounding box''', choose '''true'''.
|-
|| 03:10
|| Notice that a '''bounding box '''for the object is displayed.
|-
|| 03:16
|| This allows us to encompass the area of selected objects in the canvas.
|-
|| 03:23
|| We can also toggle this on or off from the view toolbar on the top menu.
|-
|| 03:30
|| Scroll down to object style.
|-
|| 03:33
|| Click on the pull down menu for '''Display mode''' as seen here.
|-
|| 03:38
|| '''Wireframe '''shows only the edges of the object.
|-
|| 03:44
|| I will choose '''Flat lines''' now.
|-
|| 03:48
|| This will enable us to draw a color shaded or color filled object.
|-
|| 03:54
|| Scroll down and click on the form for''' line color'''.
|-
|| 03:58
|| A '''Select color '''dialog box appears.
|-
|| 04:03
|| Some of you will have to click again for the dialog box to open.
|-
|| 04:08
|| I will choose red and click on '''OK'''.
|-
|| 04:12
|| When the object is selected, the outline is in green color.
|-
|| 04:18
|| Hence the change will not be visible at this point.
|-
|| 04:23
|| Scroll down and change the '''line width''' to 8.
|-
|| 04:28
|| Scroll down to the '''Shape color'''.
|-
|| 04:30
|| Click on the form and open the '''Select color '''option.
|-
|| 04:36
|| If the object has multiple faces, we can color the various faces differently.
|-
|| 04:43
|| I will choose an orange color and click on '''OK'''.
|-
|| 04:48
|| Notice that we can also change the transparency of the object here.
|-
|| 04:54
|| Now, pause the video, and draw a circle partially overlapping the pentagon.
|-
|| 05:01
|| Use '''flat lines''' for '''display mode''' and fill it with a color of your choice.
|-
|| 05:07
|| Then change the''' transparency''' level and notice the changes.
|-
|| 05:13
|| The color changes will be visible only when the object is not highlighted.
|-
|| 05:19
|| Next, let’s measure the distance of the side of the pentagon.
|-
|| 05:23
|| First click to select the edge of your choice.
|-
|| 05:28
|| Next, click on the '''Dimension tool''' in the '''Draft Annotation tools'''.
|-
|| 05:34
|| A line parallel to the selected line appears on the canvas.
|-
|| 05:39
|| Place it a bit away where you want the annotation to be placed.
|-
|| 05:44
|| Left click to notice the measured line and annotation.
|-
|| 05:50
|| For some of you the font size may be very small and not visible.
|-
|| 05:56
|| We can format the annotation globally or individually.
|-
|| 06:01
|| In the '''combo view''', '''model''' tab, select the '''dimension''' label.
|-
|| 06:06
|| Scroll down to the graphics section and '''line color'''.
|-
|| 06:10
|| Click once or twice depending on your system to open the '''select color''' dialog.
|-
|| 06:18
|| Choose red and click on '''OK'''.
|-
|| 06:22
|| Then, scroll to the text section in the panel below.
|-
|| 06:27
|| Go to the '''font size '''section and change it to 5 mm.
|-
|| 06:32
|| Now the text size changes.
|-
|| 06:35
|| To change the default font setting, go to '''Edit''', '''Preferences'''.
|-
|| 06:42
|| Choose the '''Draft tab''' on the left.
|-
|| 06:45
|| Then choose the''' Text and dimensions''' on top.
|-
|| 06:50
|| Set the desired parameters here for global setting.
|-
|| 06:54
|| The changes will apply only to the annotations that you will add later on.
|-
|| 07:00
|| For now I will click on '''Cancel''' as I do not want to change them.
|-
|| 07:06
|| Let us measure the distance between two user chosen points.
|-
|| 07:11
|| First click on the '''measure distance''' tool on the '''View''' toolbar.
|-
|| 07:16
|| The report view window prompts the user to pick the first point.
|-
|| 07:21
|| Click on your desired first point.
|-
|| 07:25
|| I will choose one of the vertex of the pentagon.
|-
|| 07:28
|| Then I will click on another vertex.
|-
|| 07:31
|| Notice the distance between them is now shown on the canvas.
|-
|| 07:37
|| Delete the measurements using the '''combo view''', '''model''' tab.
|-
|| 07:42
|| Select the object and delete it.
|-
|| 07:45
|| You may want to readjust the zoom level at any point.
|-
|| 07:50
|| Use the '''View''' toolbar options as seen to fit all objects or the selection.
|-
|| 07:57
|| Many of these are also available as '''context menu'''s.
|-
|| 08:02
|| Right click on the canvas with the selected object to access them.
|-
|| 08:07
|| Users must practice to get familiarity with the various tools.
|-
|| 08:13
|| Save your work if desired.
|-
|| 08:16
|| Use '''File''', '''Exit''' to close '''FreeCAD'''.
|-
|| 08:20
|| Now let's summarize.
|-
|| 08:22
|| In this tutorial, we,
|-
|| 08:24
|| Inscribed a pentagon
|-
|| 08:27
|| Formatted color and line properties
|-
|| 08:30
|| Added '''Annotation'''
|-
|| 08:32
|| Formatted the text properties
|-
|| 08:35
|| and Measured distance between two points
|-
|| 08:40
|| For assignment activity, please do the following.
|-
|| 08:44
|| Draw a rectangle
|-
|| 08:47
|| Draw a hexagon with '''A''' =25 mm.
|-
|| 08:51
|| Hint: For hexagon, '''A''' = '''r '''to inscribe on a circle.
|-
|| 08:56
|| Practice to draw and format the properties of objects.
|-
|| 09:01
|| Hint: You may also use the parameters in '''combo view''' window to modify.
