|| Welcome to this Spoken Tutorial on '''Eye end part of Knuckle Joint'''.
|-
|| 0:17
|| In this tutorial, we will learn to,
|-
|| 0:10
|| Draw an '''eye end part '''of the '''Knuckle joint '''using S'''ketcher tools'''.
|-
|| 0:15
|| To record this tutorial, I am using
|-
|| 0:18
|| '''Windows '''11''' OS '''and
|-
|| 0:20
|| '''FreeCAD'''version 0.21.2
|-
|| 0:25
|| To follow this tutorial,
|-
|| 0:27
|| Learners must be familiar with the '''FreeCAD'''interface.
|-
|| 0:30
|| For the prerequisite tutorials, please visit this site
|-
|| 0:35
|| The '''Eye end''''''part '''of the '''knuckle joint'''is used to join parts that need to pivot or rotate.
|-
|| 0:41
|| Let us open '''FreeCAD'''.
|-
|| 0:44
|| I will open a new file.
|-
|| 0:47
|| I have selected the '''PartDesign workbench'''.
|-
|| 0:50
|| Let us create a new '''Body'''.
|-
|| 0:53
|| Now select '''Create sketch '''to create a new '''Sketch'''.
|-
|| 0:59
|| Select the XY-plane and click on''' OK'''.
|-
|| 01:03
|| The workbench switches to '''Sketcher workbench'''.
|-
|| 01:07
|| Now I will select the '''Create circle'''tool from the toolbar.
|-
|| 01:11
|| Place the cursor on the centre of the plane and draw two concentric circles.
|-
|| 01:18
|| Let us set the radius of the circles using the '''Constrain radius'''tool.
|-
|| 01:24
|| Let us change the radius of the larger circle to 25''' mm'''.
|-
|| 01:30
|| Similarly change the radius of the smaller circle to 12.5 '''mm'''.
|-
|| 01:36
|| Let’s select the '''Create polyline'''tool.
|-
|| 01:40
|| The '''Polyline '''tool allows you to draw lines continuously.
|-
|| 01:44
|| Place the cursor on the left side of the outer circle.
|-
|| 01:49
|| Drag the cursor to the left to draw a horizontal line.
|-
|| 01:53
|| Left click to complete the line.
|-
|| 01:56
|| Now to draw a vertical line, drag the cursor vertically downwards.
|-
|| 02:01
|| Left click to complete it.
|-
|| 02:04
|| Now draw a horizontal line to the right to connect it to the circle.
|-
|| 02:09
|| Let us set the length of the top horizontal line to 80''' mm'''.
|-
|| 02:14
|| Click on the line, and click the '''Constrain horizontal distance'''tool.
|-
|| 02:19
|| Change the length to 80''' mm'''.
|-
|| 02:23
|| Now select both the horizontal lines and select the '''Constrain equal'''tool.
|-
|| 02:29
|| '''Constrain equal'''tool is used to make two or more drawings of equal size.
|-
|| 02:36
|| Now select the vertical line.
|-
|| 02:38
|| Set its length to 30''' mm'''using the '''Constrain vertical distance'''tool.
|-
|| 02:44
|| Now select the '''Trim edge '''tool.
|-
|| 02:49
|| '''Trim edge '''tool is used to delete a line or curve between two intersection points.
|-
|| 02:54
|| Select the arc of the outer circle that is between the horizontal lines to trim it.
|-
|| 03:01
|| Now click Close in the '''Combo view'''.
|-
|| 03:04
|| Select the top view using the '''Gizmo'''.
|-
|| 03:09
|| Go to the '''Model'''tab and select the sketch if not already selected.
|-
|| 03:13
|| Now select the '''Pad'''tool from the tool bar.
|-
|| 03:17
|| In the '''Combo View''', under Pad Parameters change the length to 30''' mm'''.
|-
|| 03:24
|| Also tick the '''Symmetric to plane '''check box.
|-
|| 03:27
|| Now click the '''OK'''button.
|-
|| 03:31
|| Now let us rotate the drawing.
|-
|| 03:34
|| Place the cursor on the centre of the component.
|-
|| 03:37
|| Press and hold the middle mouse button.
|-
|| 03:40
|| Right click and drag the cursor to the right
|-
|| 03:44
|| Now select the '''Create a datum plane'''tool from the toolbar.
|-
|| 03:48
|| It is used to create a new plane to draw the components.
|-
|| 03:53
|| Now select the back face of the square, to set it as a reference.
|-
|| 03:58
|| Then click '''OK'''in the '''Combo view'''.
|-
|| 04:02
|| You can see that a plane appears at the bottom of the component.
|-
|| 04:06
|| Select the '''datum plane'''from the '''Model '''tab if not selected.
|-
|| 04:10
|| Now select '''Create sketch'''.
|-
|| 04:13
|| Now select the arrow near the '''Create regular polygon '''tool.
|-
|| 04:18
|| It is used to draw different polygons.
|-
|| 04:21
|| In the drop down, select '''Octagon'''.
|-
|| 04:24
|| Now place the cursor in the middle of the plane.
|-
|| 04:28
|| Left click and drag to see a model drawing.
|-
|| 04:33
|| Adjust the octagon to make its sides parallel to the background square.
|-
|| 04:37
|| Now left click again to complete the octagon.
|-
|| 04:41
|| Select the left side line of the octagon.
|-
|| 04:44
|| And select the '''Constrain vertically'''tool from the toolbar.
|-
|| 04:48
|| This makes the side vertical.
|-
|| 04:51
|| Select the left side line of the octagon and the midpoint of the plane.
|-
|| 04:57
|| Select the '''Constrain distance'''tool from the toolbar.
|-
|| 05:01
|| In the Insert length dialog box, set the length as 15''' mm'''and click '''OK'''.
|-
|| 05:07
|| Observe that the octagon is perfectly placed.
|-
|| 05:11
|| Click Close in the '''Combo view'''.
|-
|| 05:14
|| Now select the sketch if not selected.
|-
|| 05:18
|| Select the '''Pad '''tool from the tool bar.
|-
|| 05:22
|| Change the length to 40''' mm'''and click '''OK'''.
|-
|| 05:27
|| Select the '''datum plane'''in the '''Combo View'''and press Space bar.
|-
|| 05:32
|| This hides the plane.
|-
|| 05:34
|| Now select the component.
|-
|| 05:37
|| In the '''Property'''tab, go to '''Data'''.
|-
|| 05:41
|| Under '''Part Design'''change the '''Refine'''value to''' True'''.
|-
|| 05:46
|| Now click anywhere in the blank space to deselect the component.
|-
|| 05:51
|| Now select '''Create a datum plane '''tool from the tool bar.
|-
|| 05:56
|| Select the bottom face of the octagon and click '''OK'''.
|-
|| 06:01
|| Now select the '''datum plane'''from the '''Model'''tab if not selected.
|-
|| 06:06
|| Now select '''Create sketch'''.
|-
|| 06:10
|| Select the '''Create circle'''tool from the tool bar.
|-
|| 06:14
|| Draw a circle from the middle of the plane.
|-
|| 06:18
|| Using the '''Constrain radius'''tool, let us set the radius as 12.5''' mm'''.
|-
|| 06:25
|| Then click Close in the '''Combo view'''.
|-
|| 06:30
|| Now select the sketch if not selected.
|-
|| 06:33
|| Select the '''Pad '''tool from the tool bar.
|-
|| 06:37
|| In the '''Combo view'''change the length to 25''' mm'''and click '''OK'''.
|-
|| 06:43
|| Now select the '''datum plane'''in the '''Combo view'''and press '''Space '''bar to hide it.
|-
|| 06:47
|| Now click anywhere in the blank space to deselect the component.
|-
|| 06:55
|| Now select the''' Create fillet'''tool from the toolbar.
|-
|| 07:00
|| Select the intersection line between the ring and the rectangle.
|-
|| 07:04
|| Repeat it for the other side also.
|-
|| 07:06
|| In the '''Combo view'''under '''Fillet parameters''', two edges are shown.
|-
|| 07:12
|| In the '''Radius '''field change the radius to 24''' mm'''.
|-
|| 07:17
|| Then click '''OK'''.
|-
|| 07:19
|| Again select the '''Create fillet'''tool from the toolbar.
|-
|| 07:23
|| When an octagon is drawn inside a square, four triangular edges are formed.
|-
|| 07:29
|| We have to smoothen these triangular edges.
|-
|| 07:31
|| Let’s rotate the drawing and select all the triangular edges as shown.
|-
|| 07:38
|| In the '''Combo View''','''Fillet Parameters '''window opens.
|-
|| 07:42
|| In the '''Preview''',all the four selected edges are shown.
|-
|| 07:46
|| In the '''Radius'''field change the radius to 3''' mm'''and click '''OK.'''
|-
|| 07:53
|| You can now see that the component is ready.
|-
|| 07:56
|| Now let us save the file with an appropriate name.
|-
|| 08:03
|| With this we come to the end of this tutorial.
|-
|| 08:07
|| Let us summarize.
|-
|| 08:09
