|| Welcome to this '''Spoken Tutorial''' on '''Introduction to Part Design Workbench'''.
|-
|| 0:06
|| In this tutorial, we will learn to,
|-
|| 0:10
|| Draw basic shapes.
|-
|| 0:11
|| Use basic '''constrains'''.
|-
|| 0:14
|| Draw the '''Flange Coupling''' component in 3D.
|-
|| 0:17
|| To record this tutorial, I am using,
|-
|| 0:20
|| '''Windows''' 11 '''OS''' and
|-
|| 0:22
|| '''FreeCAD '''version 0.21.2
|-
|| 0:26
|| To follow this tutorial,
|-
|| 0:28
|| Learners must be familiar with the '''FreeCAD''' interface.
|-
|| 0:33
|| For the prerequisite tutorials, please visit this site.
|-
|| 0:38
|| Let us now learn about '''Part design workbench'''.
|-
|| 0:41
|| This workbench provides tools for creating 3 dimensional solid objects.
|-
|| 0:47
|| Using this workbench it is possible to design precise 3D mechanical parts.
|-
|| 0:53
|| The '''Part design''' is intrinsically related to the''' Sketcher''' workbench.
|-
|| 0:59
|| The '''Sketcher''' workbench is used to create 2 dimensional geometries for use in '''Part design'''.
|-
|| 01:05
|| Let us open '''FreeCAD'''.
|-
|| 01:09
|| I will open a new file.
|-
|| 01:11
|| I have selected the '''Part Design''' workbench.
|-
|| 01:15
|| In the '''Tasks''' menu, under '''Start Part '''click on '''Create body'''.
|-
|| 01:22
|| A new '''Body''' needs to be created to draw a sketch.
|-
|| 01:25
|| Now under '''Start Body''', click on '''Create sketch'''.
|-
|| 01:30
|| This creates a sketch view where you can draw the components.
|-
|| 01:34
|| On the panel we can see three planes in 3 mutually perpendicular directions.
|-
|| 01:41
|| In the '''Combo View '''under Select feature three planes are shown.
|-
|| 01:47
|| Select XY-plane in the '''Combo View'''.
|-
|| 01:50
|| This denotes the top view.
|-
|| 01:53
|| Click the '''OK''' button to select the plane.
|-
|| 01:56
|| Observe that new tools are shown on the toolbar.
|-
|| 02:00
|| Now let us draw a vertical line from the x-axis.
|-
|| 02:05
|| Select the '''Create line''' tool from the tool bar.
|-
|| 02:08
|| Place the cursor on the x-axis line.
|-
|| 02:12
|| You can see that the x-axis line changes to yellow.
|-
|| 02:17
|| You can see that a '''Constrain point onto object''' symbol appears near the cursor.
|-
|| 02:22
|| It denotes that the point is fixed to the line.
|-
|| 02:27
|| Now click on the line to start drawing it.
|-
|| 02:30
|| Drag the mouse vertically upwards to draw a vertical line.
|-
|| 02:36
|| You can see a '''Vertical constrain''' symbol appearing near the cursor.
|-
|| 02:40
|| It represents the line drawn vertically.
|-
|| 02:43
|| Left click to complete the drawing of the line.
|-
|| 02:46
|| Now let us draw a horizontal line along the x-axis.
|-
|| 02:52
|| Make sure that the '''Create line''' tool is selected.
|-
|| 02:55
|| You can check that by seeing the symbol near the cursor.
|-
|| 02:59
|| Place the cursor on the line.
|-
|| 03:01
|| You can see the '''Constraint Point onto object''' symbol near the cursor.
|-
|| 03:06
|| Click and drag the cursor horizontally to draw a horizontal line.
|-
|| 03:11
|| Now you can see two symbols appearing near the cursor.
|-
|| 03:16
|| '''Constrain point onto object''' symbol and '''Constrain horizontal''' symbol.
|-
|| 03:21
|| We don’t want two '''Constraint point onto objects'''.
|-
|| 03:25
|| This means that the line is fixed at two points to the same object.
|-
|| 03:30
|| Upon clicking, you can see that the entire drawing has turned to red.
|-
|| 03:35
|| To clear that, click on any one of the constraints.
|-
|| 03:39
|| Press the '''Delete key''' on your keyboard to delete the '''constrain.'''
|-
|| 03:44
|| Now you can see that the drawing came back to normal.
|-
|| 03:47
|| Let us avoid the appearance of the '''Constrain Point Onto Object''' symbol twice.
|-
|| 03:52
|| To do this, let’s draw a line below the x-axis.
|-
|| 03:57
|| To deselect the tools, right-click on the panel.
|-
|| 04:00
|| Or press the '''Escape key''' to deselect the tools.
|-
|| 04:05
|| Now let us draw an arc.
|-
|| 04:08
|| Select the '''Create arc '''tool from the tool bar.
|-
|| 04:11
|| Place the cursor on the top end of the vertical line.
|-
|| 04:15
|| You can see that a X-Shaped symbol appears near the cursor.
|-
|| 04:20
|| It is the '''Constrain''' coincidence.
|-
|| 04:23
|| It denotes that the cursor is at the top of the end point.
|-
|| 04:28
|| Now left click and drag the cursor to left or right.
|-
|| 04:33
|| You can see a model circle that can be drawn.
|-
|| 04:37
|| Click to release the model circle.
|-
|| 04:40
|| Drag the cursor to start drawing the arc.
|-
|| 04:44
|| Left click again to finish the arc.
|-
|| 04:47
|| Now let us draw a circle.
|-
|| 04:50
|| Select the '''Create circle''' tool.
|-
|| 04:53
|| Place the cursor at the end of the horizontal line.
|-
|| 04:57
|| Check for the X-Symbol.
|-
|| 05:00
|| Left click and drag the cursor to draw the circle.
|-
|| 05:04
|| Once the definite size is visible, left click to finish the circle.
|-
|| 05:10
|| Observe that, we have drawn these shapes with no dimensions.
|-
|| 05:15
|| Let us assign some values to them.
|-
|| 05:18
|| Let us select the vertical line.
|-
|| 05:21
|| Select the '''Constrain vertical distance''' tool from the tool bar.
|-
|| 05:26
|| '''Insert length''' pop up appears.
|-
|| 05:29
|| In the '''Length''' field type 30 '''mm''' and click the '''OK '''button.
|-
|| 05:36
|| You can see that a dimension is applied to that line.
|-
|| 05:39
|| Now select the horizontal line and click the '''Constrain horizontal distance''' tool.
|-
|| 05:46
|| '''Insert length''' pop up appears.
|-
|| 05:50
|| In the '''Length''' field type 30 '''millimetre '''and click the''' OK '''button.
|-
|| 05:55
|| Now to set the radius of the arc, select the arc.
|-
|| 06:00
|| Select the arrow near the '''Constrain arc or circle''' tool.
|-
|| 06:06
|| In the drop down select '''Constrain radius.'''
|-
|| 06:09
|| '''Insert radius '''pop up appears.
|-
|| 06:12
|| In the '''Radius''' field type 10 '''mm''' and click '''OK'''.
|-
|| 06:17
|| Now let us give the dimensions to the circle.
|-
|| 06:21
|| To set the radius for the circle, select the circle.
|-
|| 06:26
|| Select '''Constrain radius'''.
|-
|| 06:29
|| '''Insert radius''' pop up appears.
|-
|| 06:32
|| In the '''Radius''' field type 20 '''mm''' and click '''OK'''.
|-
|| 06:37
|| In the '''Combo View '''click on the '''Close''' button to complete the sketch
|-
|| 06:42
|| Now let us use the tools to draw a '''Flange coupling'''.
|-
|| 06:47
|| Now I will open a new file.
|-
|| 06:50
|| We can select the '''Create body''' tool from the toolbar.
|-
|| 06:54
|| Then select '''Create sketch'''.
|-
|| 06:58
|| Select XY-plane and click '''OK'''.
|-
|| 07:03
|| Now let us draw two circles.
|-
|| 07:07
|| Select the '''Create circle''' tool and place the cursor on the x-axis.
|-
|| 07:12
|| You can see that line changes to yellow color.
|-
|| 07:16
|| You can see that '''Constrain point onto object''' symbol appears near the cursor.
|-
|| 07:22
|| Now click on the line to draw a circle.
|-
|| 07:26
|| Repeat the process on the other side of the x axis.
|-
|| 07:30
|| Now right click the mouse to deselect the tool.
|-
|| 07:34
|| Select the center of any one of the circles and the midpoint of the plane.
|-
|| 07:40
|| Once the points are selected they turn to green color.
|-
|| 07:44
|| Click '''Constrain Horizontal Distance''' tool.
|-
|| 07:47
|| In the '''Insert length '''dialog box, type the length as 100 '''millimetre''' and click '''OK'''.
|-
|| 07:55
|| Select the centers of both the circles and click '''Constrain Horizontal Distance''' tool.
|-
|| 08:02
|| Change the length to 200 '''mm'''.
|-
|| 08:06
|| Let us move the drawing to a convenient place to see it clearly.
|-
|| 08:11
|| Press and hold the middle mouse button to see the move cursor.
|-
|| 08:16
|| Move the mouse and place the drawing at a convenient location.
|-
|| 08:21
|| Now select the '''Create arc '''tool.
|-
|| 08:25
|| Place the cursor on the center of the circle.
|-
|| 08:29
|| You can see that midpoint changes to yellow color.
|-
|| 08:33
|| An X-shaped symbol appears near the cursor.
|-
|| 08:37
|| This denotes that the cursor is at the midpoint of the circle.
|-
|| 08:42
|| Now click on the midpoint and draw a semicircle from bottom to up.
|-
|| 08:48
|| Repeat the same process on the other side.
|-
|| 08:52
|| Let’s draw two more arcs above and below the plane from center of the plane.
|-
|| 08:59
|| Now, select the '''Line''' tool and connect all the arcs.
|-
|| 09:05
|| Make sure to click only when the X-symbol is visible.
|-
|| 09:10
|| Now select a line and the arc and select the '''Constraint''' '''Tangent '''tool.
|-
|| 09:16
|| This makes the connection between the arc and line smooth .
|-
|| 09:20
|| Repeat this process for the arcs and lines at four points to make them smoother.
|-
|| 09:28
|| Now select the top arc and click '''Constraint radius''' tool
|-
|| 09:34
