hello friends welcome to Frea tutorial
0:03
and in this tutorial we will model this
0:05
part and uh you can see that uh I have
0:08
already model it in freead and it is
0:12
matching with the isometric view of
0:14
reference drawing we will refer the
0:18
dimension of front top and side view and
0:21
uh we will uh create this part from the
0:23
scratch so for this
0:26
tutorial I am using the Frecad version
0:30
1.0 and uh for this tutorial you must
0:33
have at least Frecad version 1.0 or
0:37
higher now I will uh close this file and
0:40
I will create a new file and I will show
0:43
you from the scratch how you can model
0:45
this part
0:48
you can also visit my website
0:51
macexus.com where I write articles and
0:54
tutorials on a free CAD and you can also
0:58
access my 3D part library of a free CAD
1:03
you can download the part from here and
1:06
you can use in your projects with
1:09
modifications
1:11
you can also access my 2D drawing
1:15
library where you can uh download this
1:18
2D drawings and uh you can create 3D
1:23
models with respect to these
1:26
drawings you can also support me on
1:31
coffi.com you can buy me a cup of coffee
1:35
your small support will uh help this
1:37
channels to grow and it will motivate me
1:41
to create more awesome content on uh
1:44
free CAD you can find my Kofi donation
1:47
page link in a video description as well
1:51
as you can also see my Kofi page URL on
1:54
this
1:56
header so let's come back to our
1:59
tutorial
2:02
now I will create a new file and first
2:06
thing which I will do is to create a
2:07
body and then create a sketch and I will
2:10
select this right plane and now here we
2:14
will refer this side
2:16
view so here first we will create this
2:20
uh arc of R50 and for this uh we will
2:23
use the threepoint arc i will create a
2:27
threepoint arc and here I will select
2:30
the center and uh at a
2:34
coincidence and uh
2:36
then I will draw the two vertical
2:40
line one here and one here and uh I will
2:45
select smart
2:46
dimension and give it a value 50 and
2:52
now I will select again smart dimension
2:56
and add a
2:58
value
3:00
80 and uh from
3:03
center it is
3:11
40 and
3:14
now this is radius is constraint and now
3:19
here we will create threepoint arc at
3:23
both the sides
3:29
let's make this line shorter and uh we
3:33
will again use the threepoint arc and
3:37
create threepoint arc at the left and
3:41
right side and now we see that from
3:45
center to this center is of 20
3:49
mm so I will select a smart dimension
3:52
select this and this and add a dimension
3:56
20
3:57
mm and we have defined the vertical
4:00
position so now I will select this and
4:03
this and uh I will select horizontal
4:07
constraint so that this this is a
4:10
horizontal and
4:13
now we will again create a vertical
4:17
line and we will constrain these two
4:22
centers of a distance
4:25
115 and this is the symmetric so if you
4:30
see this centers and this center are
4:32
free to
4:34
move so we will use a symmetricity
4:36
constraint select this point this point
4:39
and this axis and uh we will select a
4:43
smart dimension and uh select this to
4:46
this and uh define here position
4:52
115
4:55
now we will create two vertical
5:00
line one is on the left hand side and
5:03
one is on the right hand side now I will
5:06
apply the constraint
5:08
vertical and uh here we will create a
5:11
threepoint
5:14
arc select a threepoint arc select this
5:17
point this point and here select this
5:21
and this and add a coincidence
5:24
constraint and here we will add a
5:28
tangency similarly we will select this
5:30
line and arc and add a tangency and
5:34
now from this center to this center is
5:37
of a 40 mm so we will select a smart
5:41
dimension and we will provide 40 mm and
5:47
now here we will stretch this line at
5:51
both the side and we will add a tangency
5:56
on both the sides left as well as on the
5:59
right side so at a tangent and
6:03
now let's see what is the
6:07
unconstrained so this radius is
6:10
unconstrained so here is a radius R 25
6:13
is given so we will select a smart
6:15
dimension and we will give it a 25 so
6:19
now you can see that uh our uh sketch is
6:23
fully constrained and now we will come
6:27
out of the sketch and uh create a pad of
6:30
10 mm if we see in this view so this is
6:34
the pad of a 10 mm so we will select the
6:37
sketch click on the pad and from here we
6:39
will set it
6:44
reverse or keep as it is and uh say
6:50
okay and
6:52
now we will create a next profile which
6:55
is this one and uh here if we see in a
7:01
side view so
7:04
first we will create a solid
7:07
rod solid profile so I will select the
7:10
face and click on the sketch and here we
7:13
will automatically get the center and
7:16
now we will create a circle of diameter
7:21
30 select the circle
7:28
and here we can see the value diameter
7:31
30 and we will extrude it to the
7:34
distance of 70
7:36
mm so select a smart
7:40
dimension give it 30 and here we will
7:43
extrude it to the distance of a 70 so
7:46
select the sketch click on the pad and
7:49
uh make it 70 and uh say okay and press
7:53
zero for isometric
7:55
view and now we will create this round
8:01
profile now we will select this face and
8:05
uh click on the sketch press zero for
8:09
isometric and rotate the model position
8:11
and set to the left
8:15
view so we will project this radius
8:20
click on the project geometry and
8:22
project this and uh select the
8:27
circle and
8:29
now this is of a diameter 30 which we
8:32
can see
8:33
here select it and give the value 30 and
8:38
now we will uh extrude it to the
8:41
distance of 20
8:51
mm close it and uh extrude it to the
8:55
distance of uh 20
9:00
mm say
9:02
okay and
9:05
now if you see our isometric view now we
9:09
will create this
9:11
face so we will directly select this
9:14
face because we have extruded to the 20
9:18
mm and we will create this slotted like
9:21
profile on this
9:25
face so we have selected the face we
9:27
will click on the sketch press zero for
9:31
isometric and uh from here switch to the
9:34
flat lines and let's rotate our model to
9:38
this position and now we will create
9:43
a a projected geometry here by
9:46
projecting this diameter and
9:50
now I will uh select the slot
9:53
tool i will create a
10:01
slot and now we will uh define the
10:07
diameter instead of that we will select
10:10
radius and uh give it a 20
10:15
mm and from here we will switch to the
10:20
wireframe so
10:21
here we will select it and made it
10:25
vertical and let's make this center
10:31
coincidence make this center
10:34
coincidence and let's add a reference
10:38
dimension from this to this and make it
10:44
reference because we require this center
10:47
to center dimension which is 40 which we
10:51
can see here in a side view so this is
10:53
the reference dimension and this is how
10:56
you can add the reference dimension now
10:58
uh we will create pad of 10 mm we have
11:03
created this profile and now this
11:05
thickness is of a 10 mm so first I will
11:09
switch to the flat lines and select this
11:12
sketch and click on the pad and from
11:15
here we will add a 10
11:18
mm and
11:20
now we will uh create this round profile
11:24
on this
11:25
face whose detail we can see here which
11:28
is of a diameter 40 so we will select
11:32
the face and uh click on the sketch and
11:35
now go to the
11:38
isometric set model to the right
11:42
orientation and
11:44
here we will project
11:46
geometry and uh select the
11:51
circle and create a
11:54
circle and now we will uh create the pad
11:59
of 30 mm select the sketch click on the
12:03
pad and say
12:06
30 so here first we will uh save our
12:15
part and now let's move to the next
12:19
feature in the next feature we will
12:22
create this cut here so for this we will
12:25
select the face and click on the
12:28
sketch and here I will uh click on the
12:31
project geometry and project this outer
12:34
diameter and here I will uh create two
12:42
circles and now I will uh select this
12:46
and this and uh made it uh
12:49
equal and uh inner diameter is of 20 mm
12:53
so I will select smart
12:55
dimension and set it 20 and now this cut
13:00
is of a 40 mm so select the sketch click
13:03
on extrude cut and say
13:07
40 and say
13:09
okay
13:11
now let's move to the next
13:14
feature next feature is to add the pad
13:18
of 5 mm so
13:23
here I will select the face and uh click
13:26
on the
13:27
sketch press zero for isometric and now
13:31
here we will project this
13:33
diameter click on project geometry and
13:37
we will project this diameter on this
13:40
face and now we will uh create a
13:45
circle here and uh we will select this
13:49
and construction and uh add equal
13:52
constraint and click on
13:55
close and add the pad of 5 mm click the
13:59
pad and uh give the pad of 5 mm and say
14:05
okay now let's uh move to the next
14:08
feature next feature is to here is a
14:14
drill of a diameter two which is the
14:16
depth of a 20 mm so we will select the
14:19
face and
14:21
uh click on the
14:23
sketch and here I will uh simply
14:27
create a
14:29
circle and uh define this
14:33
diameter 2 mm and here I will give the
14:37
depth of
14:40
20 and here give the depth 20 mm and say
14:47
okay now we will create this keyway
14:53
profile so we will uh select the face
14:55
and uh click on the
14:58
sketch and here first I will set my
15:01
model to the right
15:03
orientation and from here I will switch
15:06
to the flat lines and switch to the
15:08
right view and for better visibility I
15:11
will switch to the wireframe here so we
15:13
wanted to create a keyway profile like
15:16
here
15:19
so here I will simply select a rectangle
15:22
and uh create a
15:25
rectangle and uh here is a depth of 20
15:30
and width is of 2 mm and from the center
15:35
it is of a
15:37
7 so I will select a smart dimension
15:40
select this and this and give it a 7 mm
15:45
and now I will make it
15:47
symmetric from the axis so select this
15:51
point this point and this
15:53
axis select a smart dimension and uh
15:58
give it a 2
15:59
mm and here we wanted to remove the
16:02
material so we will uh keep this value
16:04
approximate let's give the 5 mm and now
16:08
close it so we have the profile here
16:11
select the sketch click on the cut and
16:15
uh from here give the 20
16:17
mm say
16:20
okay now let's move to the next feature
16:24
next feature is to give the fillet of 2
16:27
mm here is a
16:30
R2 so I will press control key select
16:33
this age and this age and go to the
16:35
fillet and give here 2 mm say okay
16:43
so this completes our model and uh you
16:46
can see that uh we have did everything
16:50
from the scratch and uh our uh model is
16:55
matching with the isometric view and
16:59
fillet is of R2 at all locations so if
17:04
fillet is missing somewhere you can add
17:06
the
17:11
fillet so this is all about this part
17:14
modeling tutorial and this tutorial is
17:16
designed for the beginner user of a free
17:18
CADs to understand the sketching in a
17:22
free CAD and how we can uh project
17:25
geometry give the reference
17:28
dimensions
17:30
fillets and how to read a drawing
17:34
because converting a 2D drawing into the
17:38
3D model is required the good knowledge
17:41
of a drawing
17:42
reading so this is all about this
17:45
tutorial and uh you can practice this
17:48
part with respect to the
17:51
drawing thank you for watching and thank
17:54
you for your valuable time
