hello friends welcome to Fria 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 and uh it is matching
0:12
with reference drawing isometric
0:15
view in this tutorial we will uh read
0:18
the dimensions and we will uh make this
0:21
part from the scratch so for this
0:24
tutorial I'm using the frecad version
0:27
1.0 so you must have at least fre
0:31
version 1.0 or higher
0:33
version now I will uh close this file
0:36
and create a new
0:38
file you can also visit my website
0:42
macexus.com where I write articles and
0:46
tutorials on free and you can also
0:50
access my 3D part library of a free CAD
0:55
you can download the part from here and
0:58
you can use in your projects with
1:02
modifications you can also access my 2D
1:05
drawing library where you can uh
1:09
download this 2D drawings and uh you can
1:13
create 3D models with respect to these
1:18
drawings you can also support me on
1:22
coffi.com you can buy me a cup of coffee
1:26
your small support will uh help this
1:29
channels to grow and it will motivate me
1:32
to create more awesome content on uh
1:36
free CAD you can find my Kofi donation
1:38
page link in a video description as well
1:42
as you can also see my Kofi page URL on
1:46
this
1:47
header so let's come back to our
1:50
tutorial
1:52
so here I have created a new file and uh
1:55
first thing I will do is to insert a
1:58
body and uh here is the part design
2:00
workbench which is active and
2:03
now to create this part first uh we will
2:07
uh create this revolve
2:10
profile so first we will create a half
2:13
profile and then we will revolve around
2:15
this axis
2:18
so I will on the origin and
2:21
uh if you see the isometric view so we
2:25
will uh create our revolve profile on
2:30
this right plane which is YZ plane so
2:32
plane is selected and I will uh click on
2:35
the sketch and I will go to the model
2:38
tab and hide the origin plane and
2:41
now here I will uh use the polyline
2:49
tool so polyline tool is here and now I
2:54
will create a rough profile
2:58
and
3:16
here
3:17
so this is the rough profile and now we
3:21
will uh constrain
3:23
it so if you see in a frecad version 1.0
3:27
zero once you drag the line you will see
3:30
the value
3:33
so here we will uh make it close to our
3:38
uh
3:42
requirement now the first thing which we
3:45
will do is to create this diameter and
3:48
uh we can get this value from the
3:51
drawing so let's uh see here
3:57
so here if you
3:59
see in a
4:04
section in front view we can see that
4:07
the maximum diameter is of a 10 mm so I
4:11
will select a smart
4:13
dimension and give it a 5
4:16
mm and now I will move the
4:23
line and uh this is the
4:26
21.5 select a spot dimension and give it
4:30
a
4:34
21.5 this is the
4:40
8.5 and this is of 4
4:43
mm this is of a diameter 8 so radius
4:47
will be four
4:49
and
4:51
now let's
4:53
uh constrain
4:55
this this line which is of a 9
5:03
mm and diameter here is of a 6 mm which
5:09
is
5:10
M6 so this will be the 3 mm
5:15
now here I will move the dimension so
5:18
that uh you can clearly see the
5:28
value
5:31
now I will uh close the profile and uh
5:35
here I will click on the revolve tool
5:38
and
5:38
here we will revolve our profile with
5:42
respect to y-axis so we will go here and
5:44
select a y-axis and say
5:51
okay so this is the base profile and now
5:56
let's
5:58
uh create the next feature so our next
6:02
feature with respect to the isometric
6:04
view we will create this
6:07
profile and whose dimension is given in
6:11
this view so I will select the face and
6:14
click on the
6:15
sketch and here I will uh set it
6:19
isometric and set it to the front and
6:22
now here first thing which I will do is
6:26
to create this uh construction
6:30
circle select the circle tool and create
6:33
a circle and uh make it construction
6:38
so here is the options to toggle from uh
6:41
regular geometry to the construction and
6:44
now the diameter is of 20.5 so select
6:49
the
6:50
diameter and give the
6:53
20.5 and
6:55
now here we will create a threepoint arc
6:59
here is a diameter uh dimension is four
7:02
so we will create a threepoint arc we
7:05
will go here and select a threepoint
7:11
arc and here we will use the
7:15
symmetricity select this point this
7:18
point and this
7:20
axis and now this point is symmetric now
7:23
we will select the dimensions tool
7:26
select this point and this point and uh
7:30
provide the 4 mm and
7:33
now we will uh create a threepoint arc
7:37
again to create this
7:40
profile so here I will create a rough
7:43
threepoint
7:44
arc and select this point this point and
7:49
uh add a coincidence and now select this
7:53
and this and uh made
7:56
it equal and now I will uh drag this
8:01
point and
8:03
now I will uh draw the two horizontal
8:06
line one is on the left one is on the
8:08
right and then I will connect with this
8:11
points so select this point and
8:17
uh create the same thing on the other
8:21
side and join it and now this dimension
8:26
is of a 12 mm so we will make this point
8:30
and this point symmetric with respect to
8:33
axis so we will click on the
8:35
symmetricity select this point this
8:38
point and the axis so you can see that
8:41
uh symmetricity point is added now I
8:44
will select a dimensions tool select
8:47
this point and this point and add the
8:50
dimensions 12 now here if you see this
8:55
point is unconstrained which is of 1.2
8:58
mm from the origin so we will select
9:01
this and this and give it 1.2
9:06
mm and now we will move these dimensions
9:10
and now
9:11
here our uh sketch is fully constrained
9:15
and uh we will come out of the sketch
9:18
and we will create a pad of 3 mm so if
9:22
you see
9:23
here so if
9:25
we 4 + 2 6 and uh 9 - 6 is 3 so this
9:31
thickness is of 3 mm so select the
9:34
sketch and click on the
9:36
pad and provide here the 3
9:40
mm so we can see that uh solid profile
9:43
we have made and now we will add
9:47
uh this cut features to our part whose
9:51
details we can see in the section view
9:57
now let's uh save our part
10:07
now let's uh on the origin plane and we
10:11
will select this YZ plane to create this
10:15
cut
10:17
profile so select the sketch and
10:22
here we will place our model to the
10:24
isometric view and uh we will switch to
10:28
the flat
10:31
lines first switch to the shaded and
10:33
then switch to the flat lines
10:42
now we will uh hide the origin plane and
10:46
let's switch to the wireframe view and
10:49
now here we will uh click on the project
10:52
geometry and we will project this
10:55
edges and here I will uh select the line
11:00
tool
11:04
and
11:06
now let's uh first constraint this line
11:09
select a smart dimension and uh provide
11:13
it uh
11:18
4.75 and uh move these dimensions and
11:22
now select a polyline tool and create a
11:26
rough cut
11:31
profile and close the
11:36
profile
11:38
now let's constrain it so here is a 21.3
11:42
which is the overall cut length so
11:44
select a smart dimension and give this
11:48
uh
11:50
21.3 and uh this radius is of
11:55
3.25
11:57
and this is of 5 mm which we can see
12:01
here and now we will close it so our
12:06
profile is fully closed and select the
12:10
sketch and click on the groove and here
12:13
we will uh select our reference and we
12:16
will select this
12:18
y-axis and uh you can see that cut has
12:22
been created
12:25
now press our model to the
12:28
isometric and now we will move to the
12:30
next
12:32
feature which is we will now add the
12:36
material here so we will select the face
12:41
and uh we can read the dimension from
12:46
here now face is selected i will click
12:50
on the sketch and now I will uh switch
12:53
to the isometric view and make this
12:55
front plane normal and now on this axis
13:00
I will create a
13:03
circle and uh this is of diameter
13:09
4.5 and uh vertical height is of 7.5
13:19
and now I will close
13:21
it and uh this is of 6 mm 4 + 2 is 6
13:26
select the sketch click on the pad and
13:30
give it a 6 mm and say
13:34
okay and
13:36
now there is a
13:38
cut so we will select the face and click
13:42
on the sketch
13:44
and here let's switch to the isometric
13:47
and make this front plane normal and now
13:50
we will click on the project geometry
13:53
and project this outer diameter and here
13:58
select the circle and create a circle
14:01
now press the control key select this
14:04
newly created circle and this uh
14:06
projected diameter and uh click on this
14:10
equal constraint so this is the equal
14:13
and now we have to create a 4 mm
14:16
diameter so we will select a
14:20
circle and select a smart
14:23
dimension and uh make this 4 mm now I
14:27
will close it now there is a cut of a 4
14:30
mm so we will select the sketch click on
14:32
the cut and define this cut length of 4
14:37
mm say okay so this feature is created
14:42
now we will uh create this cut to create
14:46
this cut we will on the origin plane and
14:49
uh we will select this top plane and
14:52
click on the sketch and now we will
14:55
switch to the
14:58
isometric go to the model tab and off
15:00
the origin and from here we
15:03
will switch to the flat lines and now
15:07
here I will select a rectangle tool
15:12
and create a rectangle and
15:16
now let's uh switch to the wireframe
15:21
view and
15:24
here we will create fillet select the
15:28
fillet and select this and this and this
15:31
and this and uh select this fillet and
15:35
this fillet and made it equal and uh
15:38
this is the R
15:41
1.5 select the radius and uh give it uh
15:46
1.5 and
15:48
now we will uh constrain
15:52
it so first thing which we will do is
15:59
to provide the position and the cut
16:03
depth cut depth is of 11.5 so we will
16:06
give it uh
16:09
11.5 position is of a 6 mm so we will
16:13
select this point this point and uh give
16:17
the 6
16:18
mm and
16:23
now this is unconstrained which is of 5
16:32
mm select the smart dimension select
16:35
this point and this
16:38
line 5 mm and
16:41
now let's uh switch to the isometric
16:45
view so now if you see we wanted to
16:49
create a
16:54
cut so now let's uh moves to this
16:58
position of the sections
17:04
go to the bottom view and now position
17:07
is of 3 mm so we will move it and we
17:11
will rotate our model and we will
17:14
project this diameter click on the
17:16
project and project this
17:19
diameter and uh from this point to this
17:23
point is of a 3 mm
17:33
so this is the cut profile and this 5 mm
17:36
is
17:37
approximately because I want this cut
17:40
profile outside of the body now we will
17:43
switch to the flat
17:45
lines so this 5 mm dimension is
17:50
approximate you can keep it 4 mm or more
17:53
than 5 mm our main intention is to
17:55
remove the material
17:59
now we will uh close our
18:02
profile and we will select the sketch
18:05
and click on the
18:07
cut and here I will click on symmetric
18:11
to the plane and set it true all and say
18:16
okay so you can see that uh this cut is
18:21
created and
18:24
now move to the next step
18:28
which is
18:29
to provide the chamfer chamfer of 1 mm
18:33
if we see here so here is a 1 by one so
18:38
I will select this H and uh click on the
18:41
chamfer and give it a 1 mm say
18:46
okay
18:48
now if
18:50
we see here here is a R10 is given so we
18:57
will uh select this age and give the
19:00
fillet of 10
19:04
mm say
19:07
okay and this R 1.5 we have given in the
19:11
sketch and now here is a chamfer
19:18
of.5 so select this edge click on the
19:23
chamfer and uh give here the
19:28
0.5 say
19:33
okay
19:35
and let's see what is the
19:41
remaining so we have completed this uh
19:45
model and let's switch to the isometric
19:49
view and isometric view of our reference
19:52
drawing so you can see that we have
19:56
exactly modeled this part in freead with
19:59
the help of uh part design workbench you
20:03
can uh refer this drawing and uh follow
20:06
the tutorials and create this model from
20:11
your end and this tutorial is designed
20:13
for the beginner user to get familiar
20:16
with the part design workbench and the
20:18
core feature of a modeling like extrude
20:21
revolve groove fillet and chamfers so
20:25
this is all about this tutorial thank
20:28
you for watching and thank you for your
20:30
valuable time
