hello friends welcome to Fria tutorial
0:03
and in this tutorial we will model this
0:05
part and you can see that uh I have
0:08
already modeled it and uh it is matching
0:11
with the isometric view of our uh
0:15
reference drawing we will create this
0:18
part from the scratch by referring the
0:20
dimension of the sections and front view
0:24
so I will uh close this file and uh
0:26
create a new file and for this tutorial
0:30
I'm using the frecad version
0:33
1.0 so you must have at least fread
0:37
version 1.0 or higher
0:39
version so let's close this file and uh
0:43
start this tutorial from the scratch you
0:46
can also visit my website
0:49
macexus.com where I write articles and
0:52
tutorials on a freecad and you can also
0:56
access my 3D part library of a free CAD
1:01
you can download the part from here and
1:04
you can use in your projects with
1:07
modifications
1:09
you can also access my 2D drawing
1:12
library where you can u download this 2D
1:17
drawings and uh you can create 3D models
1:22
with respect to these
1:24
drawings you can also support me on
1:29
coffi.com you can buy me a cup of coffee
1:33
your small support will uh help this
1:35
channels to grow and it will motivate me
1:39
to create more awesome content on uh
1:42
free cat you can find my Kofi donation
1:45
page link in a video description as well
1:49
as you can also see my Kofi page URL on
1:52
this
1:54
header so let's come back to our
1:57
tutorial
1:59
so here I have created a new file and uh
2:03
first thing which I will do is to insert
2:05
a body and then I will on the origin
2:08
plane and we will uh create our first
2:13
sketch so our first sketch will be the
2:16
revolve profile and uh as per our part
2:20
orientations we will create our first
2:23
sketch on a right plane so this is the
2:27
YZ plane and I will select the plane and
2:31
click on the
2:32
sketch and now go to the model tab press
2:36
the space bar and hide this origin and
2:39
now I will simply click on rectangle and
2:42
uh create a rectangle and here I will
2:46
give the smart dimension of uh 200
2:51
mm and
2:54
uh here this is of 50
3:05
mm our uh sketch is fully constrained
3:08
and now we will create this revolve
3:12
profile so come out of the
3:16
sketch press zero and now here we will
3:20
click on the
3:22
revolve and here we will revolve our
3:26
sketch with respect to y-axis and here
3:29
fread has choose the z axis so we will
3:33
select the
3:35
y-axis and uh you can see that uh our
3:39
part is revolved now say
3:42
okay now we will uh create a next
3:45
feature and for the next feature we will
3:48
create a DATM plane at a distance of
3:55
20 because our total width is of a 200
4:00
and this is a 160 so here 20 is given so
4:04
this face is a 20 mm offset from the
4:08
face so we will select this phase and uh
4:11
we will click on the create a datm plane
4:14
and uh here in a Z direction I will give
4:20
the 20
4:21
mm so here plane is going outside of the
4:25
body so we will change the sign instead
4:28
of a plus I will give the
4:30
minus and say okay now I will uh press
4:36
to the isometric view and
4:39
now we will create our
4:42
sketch which is this
4:45
one so select the datam plane and click
4:48
on the
4:49
sketch and here we will press zero to
4:54
set our model at right orientation so we
4:57
will uh select this
4:59
front and now here we will uh project
5:04
this
5:08
diameter and uh let's switch to the
5:16
wireframe and now we will select a
5:19
threepoint
5:25
arc so here I have a selected a
5:28
threeoint arc and uh I will create a arc
5:32
and I will merge this
5:36
center say
5:37
coincidence and now I will uh draw the
5:41
vertical lines select the line
5:44
tool and uh draw the vertical
5:49
line and I will select the vertical and
5:53
join this with
5:55
this and uh I will select a line
6:01
tool and uh make it
6:04
uh
6:06
horizontal and
6:08
now we will provide the
6:12
height and before that let's make it
6:16
symmetric these two points so click on
6:18
the symmetricity select this point this
6:20
point and this
6:22
axis and uh from here select the
6:26
horizontal dimension of
6:28
56 and from center to this point is of
6:35
156 and uh click on the close and now
6:39
here I will
6:41
uh hide this data plane and from here I
6:45
will switch to the flat lines now select
6:48
the sketch click on the pad and here
6:51
provide the distance of 20 mm but in a
6:56
reverse directions now say okay now we
7:00
will move to the next feature next
7:02
feature is to create this
7:04
profile so select the face and uh click
7:07
on the sketch press zero for isometric
7:11
view and right orientation
7:14
and
7:15
now click on the project geometry and
7:18
project this
7:20
diameter and
7:22
now create a threepoint
7:25
arc select this and this and create a
7:28
threepoint arc and let's create a
7:33
similar profile which is shown here so
7:38
we will select line tool and add a
7:41
vertical line
7:44
and
7:48
uh add a coincidence here now here if
7:53
you see this is the 16 mm is a given and
7:57
uh if we add the distance we will get a
7:59
height of this point from the center so
8:04
I will select these two points and add a
8:06
smart dimension which is a 56 +
8:12
16 and
8:14
now I will move this point to the town
8:18
now I will define the vertical height of
8:22
16 so select it and define the height 16
8:27
and here I will select this point and
8:30
this point and we will add the
8:34
horizontal constraint so here it took
8:36
the
8:43
vertical
8:48
now we will make this line
8:52
vertical and now let's see what is the
8:56
unconstrain so
8:59
here if you see this is the
9:03
projection line we have to project and
9:06
add a coincidence so we will click on
9:09
the project geometry and select this
9:12
vertical
9:13
edges and we will simply select this
9:17
projected edge and add a coincidence
9:21
select this and this and add a
9:24
coincidence so our sketch is fully
9:27
constrained now select the sketch click
9:29
on the
9:30
pad and from here we will select end
9:34
condition up to face and we will select
9:36
this face and say
9:39
okay now we will uh create the next
9:43
features next feature is to create a
9:47
DATM plane at a distance of
9:50
100 so select the face and click on the
9:54
DATM and in a Z direction provide the
9:58
100 mm and uh make it
10:04
reverse and say okay
10:10
now we will uh rebuild this and we will
10:14
mirror this feature on the other side
10:17
and uh we will use the
10:19
reference to mirror is our newly created
10:22
data plane so here I will press the
10:25
control key select this pad and pad
10:28
0001 and uh let's move this mirror tool
10:33
here and now we will uh click on the
10:35
mirror
10:36
option so you can see that uh our
10:40
selected feature is added here but we
10:43
will define our own reference select
10:46
reference and we will select this datam
10:49
plane so once we selected that data
10:52
plane our feature is got mirror on the
10:55
other
10:56
side now let's uh hide this data
11:03
plane now we will uh create this feature
11:07
on the
11:09
side so we will select the face and
11:12
click on the sketch press zero for
11:15
isometric view and now we will click on
11:19
the project geometry and
11:22
uh project this radius now switch to the
11:26
rear view and rotate our model and now
11:30
we will uh read the dimension here so
11:32
first thing which we will do is to
11:34
create a threepoint
11:36
arc so I will create a threepoint arc
11:40
here and uh add a coincidence constraint
11:43
between this axis and this uh arc
11:46
center add a coincidence and
11:50
now select radius tool and provide 25
11:55
dimension and now here I will again
11:58
create one threepoint
12:04
arc and now here I will select this and
12:08
this and add a
12:09
coincidence and now here I will uh join
12:14
these two points with line on both the
12:18
side select this and this and this and
12:23
this and now here I will add a
12:27
tangency on both the side
12:32
and now if you
12:35
see this angle is not defined so we will
12:39
define
12:40
it so here is a 63 so intersection we
12:44
will consider 63 here
12:48
so we will select a smart
12:51
dimension
12:58
and select uh horizontal dimension from
13:03
this to
13:05
this
13:07
let's software define whether it is
13:10
a horizontal or vertical so here is a
13:15
63 and uh I will give it a
13:20
63ide by
13:22
2 and now center to center distance is
13:25
of 88 which we can see here so I will
13:29
select the dimensions
13:31
tool and
13:41
uh let's make it
13:44
symmetric select this point this point
13:47
and this axis so here we are getting a
13:56
conflict so we will uh divide this by
14:02
two 63ide by 2 select this point and
14:08
this and add
14:11
88
14:13
now if you see
14:15
here so this constraint
14:19
got disturbs so I will add a coincidence
14:23
and uh let's see what is
14:26
unconstrained center is a fix but we
14:30
will make it
14:33
equal so our profile become constraint
14:37
now we will come out of the sketch and
14:40
uh we will create the pad of 50 mm which
14:45
we can see here so select the sketch
14:48
click on the
14:50
pad and uh from here select reverse and
14:54
say
14:56
50 and say
15:01
okay
15:03
now we will uh create this
15:06
feature so for this we require a datam
15:10
plane at a distance of
15:13
63 so we will on our origin
15:18
plane and we will select this top plane
15:21
and click on the datam plane and here we
15:24
will uh provide the Z direction 63
15:28
mm and here we will reverse the signs to
15:33
minus so that our datim plane get shift
15:36
on the other side say okay
15:40
now I will off the origin plane and I
15:43
will rebuild my DATM plane now on this
15:46
plane we will create our
15:50
sketch so for this we will uh rotate our
15:55
model and
15:57
here first we will project this
16:03
age and now I will switch to the bottom
16:07
view and from here I will switch to the
16:10
wireframe and
16:13
now I will create a
16:17
circle and this is of a diameter 40
16:26
and I will create two horizontal
16:31
line first let's off this data plane and
16:36
now let's create two horizontal
16:39
line one at a top and one at a bottom
16:42
and now I will select this and add a
16:47
tangency
16:48
select this and add a tangency now I
16:52
will use the trim tool to remove the
16:55
extra
16:59
geometry and also remove
17:03
this and uh select the line tool and uh
17:06
close
17:07
our
17:10
profile
17:13
now if you
17:16
see from
17:19
here this center to the age is of 60 so
17:25
we will uh click on the project geometry
17:28
and project this
17:30
radius and select smart dimension and
17:34
select this and this and add
17:38
60 our uh sketch is fully
17:42
constrained and now I will close
17:46
it and from here we will switch to the
17:50
flat
17:52
lines first switch to the shaded and
17:55
then flat lines now we can see our
17:58
sketch and model clearly now we will
18:01
select the sketch and click on the
18:04
pad and here we will select end
18:08
condition up to face and we will select
18:11
this
18:12
diameter and say
18:18
okay so our feature is created but if
18:22
you see in a section view there is a
18:24
revolve cut so here if you see that uh I
18:29
have a first did to add the material
18:32
addition operations so first you have to
18:34
do the material addition operation and
18:37
then material subtraction operation like
18:40
a pocket groove and at the end you must
18:43
give the fillet and chamfer at the last
18:46
so this is the right practice to create
18:48
a model now I will on the origin plane
18:52
and I will select this YZ plane and
18:55
create our sketch and uh I will switch
18:58
to the wireframe view and let's hide our
19:02
origin plane and now I will select a
19:06
polyline
19:08
tool and I will create first a rough
19:12
profile
19:21
and close our profile now
19:25
here if you see this point is not
19:28
attached and this line is not horizontal
19:31
so first we will make it horizontal and
19:34
we will project this
19:37
edge and here I will uh select this
19:42
point and line and add a coincidence so
19:45
this side is a constraint this side is a
19:47
constraint and now let's uh add a
19:51
diameter
19:53
value so first this is
19:57
of radius
20:01
35 and this radius is of
20:06
uh
20:10
37.5 and this is the
20:15
38 and uh this is of
20:19
87 and this line is not vertical so add
20:23
a vertical and here select this point
20:28
and this point and add a horizontal
20:33
constraint so we can see that uh our uh
20:37
sketch is fully constrained we will come
20:40
out of
20:41
it and here we will select the sketch
20:44
and click on the group
20:47
tool and now
20:49
here we will uh select our own
20:57
reference along the y-axis so groove is
21:01
created
21:04
now if you see our isometric model so
21:08
here is a hole whose detail is given
21:10
here which is of a diameter
21:12
25 so this is a clearance hole so I'm
21:15
not using the whole tool i will make
21:18
this with the pocket but you can also
21:20
use this whole tool which is a right
21:22
practice now let's select the face and
21:26
click on the
21:30
sketch go to the rear
21:33
view rotate and we will project this
21:37
radius so that we get a
21:39
center so project it we got the center
21:43
and now we will uh simply
21:49
click circle and uh give it a diameter
21:54
25 now here you can set it through all
22:00
click on the pocket and
22:03
here we can set it true all because
22:06
there is a no any material but I would
22:08
recommend to use up to face and limit
22:11
this condition up to this face say
22:16
okay
22:19
now there is a hole which is through
22:22
from the both the faces so I will select
22:26
the face and click on the sketch
22:29
press uh zero for isometric and here I
22:33
will
22:34
uh select a circle switch to the front
22:38
view and
22:40
uh this is the diameter of a 14 which we
22:44
can see here 2 into diameter 14 and its
22:47
position is given here
22:50
so select a diameter and give the 14 mm
22:56
and from center to this center is of
23:07
106 click on close so this hole is
23:10
through so we will click on the
23:14
cut and
23:16
uh say through say okay
23:22
now let's move to the section view and
23:25
there is a
23:27
fillet of a 2.5 r5 is wrong r5 will not
23:34
fit here
23:37
so we will uh press the control
23:41
key and select this internal edges
23:48
you can select the fillet and add the
23:51
edges now I will give the fillet of uh
23:57
2.5 say okay so
24:02
here we will give
24:05
the
24:07
2
24:10
499 now it will work so fillet is given
24:15
and uh we can see this fillet inside
24:21
here
24:23
now press zero now if you see from the
24:26
bottom so there is a one
24:28
hole which is of a diameter
24:32
16 to get the center we will select this
24:35
face and project this radius
24:38
so it will be easy for us so click on
24:41
project geometry and project this radius
24:45
select the circle tool and create a
24:48
circle and define the diameter
24:52
16 and now close it
24:56
now click on the
25:00
cut and uh we will set a depth to the 35
25:04
mm which is
25:09
approximate because our requirement is
25:13
it open in the free area so here I have
25:17
given the
25:18
35 say
25:22
okay now if you see the here there is a
25:26
fillet of
25:28
R12 so I will click on the fillet
25:32
tool define the value
25:36
12 and select this
25:40
age this age and
25:45
uh zoom and select this edge and say
25:51
okay so you can see that R12 fillet is
25:57
added so this completes our model and
26:02
here is also the fillet of
26:04
R12 which uh we can add
26:15
so this completes our model and we have
26:18
successively converted this orthographic
26:20
drawing into the 3D model let's save our
26:31
part
26:33
so this tutorial is designed for the
26:35
beginner user of a free CAD those who
26:37
have just started learning the free CAD
26:40
and uh this part will give you the basic
26:44
overview of the solid part modeling in
26:47
frecad and uh here we have used the pad
26:52
data plane pocket grooves and fillets so
26:57
this is all about this tutorial how to
26:59
model this part with the help of a part
27:02
design workbench thank you for watching
27:04
and thank you for your valuable time
