| 0:00 | 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. |
| 04:55 | Now let us change the workbench from Draft to TechDraw. |
| 05:00 | Click on Insert Page using Template tool on the toolbar. |
| 05:05 | Select a Template File window opens. |
| 05:09 | In this window you can select the drawing templates as per your choice. |
| 05:14 | Click the Open button to load the selected template. |
| 05:17 | You can see a table at the bottom right corner. |
| 05:22 | In this table you can observe the green coloured editable text fields. |

| 06:39 | Now you can see that new tools are available to label the drawing. |
| 06:44 | Now let us show the diameter of the outer circle. |
| 06:48 | Click on the circumference of the outer circle. |
| 06:51 | Select the Insert Diameter Dimension tool to mark the diameter of the outer circle. |
| 06:58 | The diameter is shown as 100 millimetres. |
| 07:02 | Click and drag the phi value to see the line and value clearly. |
| 07:07 | Double click on the phi value to open the Dimension dialog box in the Combo View. |
| 07:13 | You can change the tolerance value for the upper limit and lower limit values. |
| 07:18 | I will change the Overtolerance value to +/ -0.05 mm |
| 07:25 | Uncheck the Equal Tolernace checkbox. |
| 07:28 | Click the FilpArrowheads checkbox to flip and unflip the arrow heads. |
| 07:33 | Click on OK button. |
| 07:35 | Now repeat the process for the next circle. |
| 07:40 | Find the diameter and change the Overtolerance value. |
| 07:48 | Click on OK button |
| 07:51 | Select the smaller circle and select the Insert Balloon Annotation tool. |
| 07:57 | We can change the properties of the balloon by double-clicking on it. |
| 08:02 | In the Combo View, the Balloon dialog box opens. |
| 08:06 | In the Bubble Shape field observe a small circle with an arrow. |
| 08:11 | You can change the bubble shape to rectangle. |
| 08:15 | Now change the text to 8X Dia 8(8 times dia 8). |
| 08:19 | It denotes that there are eight similar circles with diameter of 8 millimetres. |
| 08:25 | Draw another balloon for the outer circle. |
| 08:28 | Select the balloon. |
| 08:30 | Go to TechDraw on the menu bar. |
| 08:33 | Navigate and select Extensions: Attributes/Modifications option. |

| 09:12 | Type another vertical bar and finally select M. |
| 09:17 | Now click the OK button at the top of the dialog box to accept the changes. |
| 09:23 | Let us change the bubble shape to rectangle. |
| 09:29 | You can add surface finish value by clicking the area to be surface finished. |
| 09:35 | Click the area to be surface finished, |

| 10:04 | Let us summarize. |
| 10:07 | In this tutorial, we |
| 10:09 | Drew the Flange coupling component |
| 10:12 | Converted the diagram from Draft workbench to TechDraw workbench |
| 10:16 | Annotated the dimensions and tolerance values. |
| 10:21 | For the assignment activity, please do the following. |
| 10:25 | Practice dimensioning tools. |
