|| Welcome to this '''spoken tutorial''' on '''Industrial Drawing'''. 
|-
|| 0:05
|| In this tutorial, we will learn to, 
|-
|| 0:07
|| Draw the '''Flange coupling '''component. 
|-
|| 0:10
|| Convert the diagram from '''Draft''' workbench to '''TechDraw''' '''workbench '''
|-
|| 0:15
|| Annotate the dimensions and tolerance values. 
|-
|| 0:19
|| To record this tutorial, I am using '''Windows 11 '''OS and '''FreeCAD '''version 0.21.2 
|-
|| 0:28
|| To follow this tutorial,
|-
|| 0:29
|| Learners must be familiar with the '''FreeCAD''' interface. 
|-
|| 0:33
|| For pre-requisite tutorials, please visit this website. 
|-
|| 0:37
|| Industrial drawing is a graphical language. 
|-
|| 0:41
|| It gives information about dimensions, tolerances, and geometries of an object.
|-
|| 0:48
|| '''Flange Coupling. '''
|-
|| 0:49
|| It is a mechanical device that connects two shafts or pipes together.
|-
|| 0:55
|| It transmits power or flow of substance from one shaft to another.''' '''
|-
|| 01:02
|| We will now draw this industrial drawing. 
|-
|| 01:05
|| Let us open '''FreeCAD. '''
|-
|| 01:08
|| Click on '''File''' and select '''New.''' 
|-
|| 01:11
|| I have selected the '''Draft''' workbench.
|-
|| 01:14
|| Select '''Top''' view and '''Orthographic''' view using the '''Gizmo'''.''' '''
|-
|| 01:19
|| Please ensure that '''Snap''' '''Center''' point and '''Snap''' '''Endpoint''' tools are enabled. 
|-
|| 01:26
|| Select the '''Circle''' tool from the tool bar. 
|-
|| 01;30
|| In the '''Combo View''' check the '''Continue''' check box. 
|-
|| 01:34
|| Uncheck '''Filled''' checkbox if it is checked for you. 
|-
|| 01:38
|| Let us draw a circle of radius 50 '''millimetres'''. 
|-
|| 01:43
|| Let us continue to draw concentric circles using the same centre. 
|-
|| 01:48
|| Place the cursor on the circumference. 
|-
|| 01:51
|| It is highlighted in yellow colour and white coloured centre point is visible. 
|-
|| 01:57
|| Now click on the circumference and drag to see the radius. 
|-
|| 02:02
|| In the '''Radius''' field change the radius to 43 '''millimetres'''. 
|-
|| 02:07
|| Now let us draw the third circle with radius 28.8 '''millimetres'''. 
|-
|| 02:13
|| I will continue to draw circles using the same center point. 
|-
|| 02:18
|| The radii of the circles are 22.3 '''millimetres''', 
|-
|| 02:25
|| 21 '''millimetres''', 
|-
|| 02:29
|| 18 '''millimetres''',
|-
|| 02:33
|| and 10 '''millimetres''' respectively. 
|-
|| 02:36
|| Click on '''Close''' button in the '''Combo''' '''View'''. 
|-
|| 02:40
|| I will now draw a line from the centre of the circle to the outermost circle. 
|-
|| 02:45
|| Click on the '''Line''' tool 
|-
|| 02:47
|| For this please enable the '''Snap''' '''Endpoint''' tool. 
|-
|| 02:53
|| Click on '''Close''' button in the '''Combo''' '''View'''. 
|-
|| 02:58
|| Select the '''Line''' tool. 
|-
|| 03:00
|| In the '''Draft''' '''snap''' toolbar, click on '''Polar''' '''Array''' from the '''Array''' dropdown. 
|-
|| 03:05
|| The '''Polar''' '''Array''' menu opens in the '''Combo''' '''View'''.
|-
|| 03:11
|| In the '''Number''' '''of''' '''elements''' field choose 4 . 
|-
|| 03:13
|| Click on the circumference in order to see the centre of the circle. 
|-
|| 03:19
|| Now we see four lines dividing the circles into four parts. 
|-
|| 03:24
|| Press '''Ctrl''' '''key''' and left click on the lines to select them. 
|-
|| 03:29
|| In the '''Property''' tab change the draw style from '''Solid''' to '''Dashdot'''. 
|-
|| 03:35
|| Notice that the lines change from solid format to dashdot format. 
|-
|| 03:40
|| Let’s draw a circle of radius 4 '''mm''' at the intersection of the line and second circle. 
|-
|| 03:47
|| Let us change its radius to 4 '''mm''' in the radius field.
|-
|| 03:52
|| Click on the '''Close''' button to close the '''Circle''' tool.
|-
|| 03:56
|| Click on the drawn circle. 
|-
|| 03:58
|| Click on the '''Polar''' '''array''' from the toolbar. 
|-
|| 04:01
|| Let us change the number of elements to 8. 
|-
|| 04:04
|| Click the circumference of this circle to ensure the centre. 
|-
|| 04:09
|| Observe that eight circles are drawn at a 45 degree interval with center point. 
|-
|| 04:14
|| Let us select circles of the drawing. 
|-
|| 04:18
|| Press and hold the '''Ctrl''' '''key''' and click on all the circles one by one.
|-
|| 04:24
|| In the '''Property''' tab change the '''Angular''' '''deflection''' from 28 to 1 degree. 
|-
|| 04:30
|| And change '''Deviation''' from 0.5 to 0.1. 
|-
|| 04:35
|| Press '''Enter''' to apply the changes.
|-
|| 04:38
|| This is done to get perfect circularity in the drawing. 
|-
|| 04:42
|| Now let us save the file. 
|-
|| 04:45
|| Save the file in your convenient location. 
|-
|| 04:49
|| Type the filename as '''Industrialdrawing''' and click on '''Save''' button.
