hello friends welcome to free tutorial
0:03
and in this tutorial we will uh model
0:05
this part and you can see that I have
0:08
already model it and uh our freet model
0:12
is matching with the reference drawing
0:14
isometric
0:16
view we will uh do this part with the
0:19
help of a part design workbench and uh
0:21
for this part modeling tutorial I'm
0:24
using the frecad version 1.0 so for this
0:27
tutorial you must have at least fread
0:30
version 1.0 or higher version if you are
0:33
using the development version
0:36
or weekly builds of a frecat so make
0:40
sure you must have at least 1.0 or
0:42
higher now I will uh close this file and
0:45
uh create a new file
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
so here I have created a new file and I
2:05
have activated my part design workbench
2:08
and and now here I will uh insert my
2:16
body and I will on my origin
2:21
plane and the first thing which we will
2:24
do if we see our isometric view so first
2:27
we will create this
2:31
profile and for this we will select this
2:34
exact plane and click on the
2:36
sketch and here I will of the origin
2:40
plane and
2:43
now if you see this section view so we
2:46
will create this profile from the
2:49
axis which will touch this axis so I
2:54
will select a polyline tool and draw a
2:57
line and
2:59
then I will uh create a
3:04
triangle and now here I will uh create a
3:08
fillet select this line and this line
3:11
and
3:12
now the angle between is of uh 12.11 so
3:18
we will select smart
3:20
dimension and
3:25
uh and now let's uh move our uh sketcher
3:31
dimension tool
3:33
here and
3:35
now we will fix this
3:38
center so select a smart
3:41
dimension and uh provide this dimension
3:45
45
3:50
and the radius is of R15 which we can
3:54
see here so we will also con constrain
3:56
the radius which is of 15 mm and now
4:00
let's uh move the
4:04
dimensions and uh we will come out of
4:07
the
4:07
sketch press zero for isometric so this
4:10
is our first profile and now we will
4:13
extrude it to the distance of 40
4:17
mm we can see this dimension here so we
4:20
will extrude it and uh we will make it
4:23
symmetric to this axis so we will select
4:26
the sketch and click on the pad and uh
4:30
give the value 40 and tick mark here
4:33
symmetric to the plane and uh say
4:36
okay and
4:38
now we will create a
4:41
cut so we will select this top face and
4:44
click on the
4:46
sketch now press zero for right
4:52
orientation and we will create a circle
4:56
and uh this is of a diameter 40 because
4:59
here is a radius is R20 so select smart
5:03
dimension and provide the 40 mm and
5:06
click on the close and we will simply
5:10
remove the material and we will set in
5:12
conditions through
5:14
all and now say okay so here we have
5:20
created this cut and now we will add the
5:25
material here here we have created the
5:29
cut and now we will add a
5:50
material now we will add a material so
5:53
we will again select this face and click
5:56
on the sketch
5:57
press zero for right
6:01
orientation and uh set our cube like
6:05
this and now here we will create these
6:08
two
6:09
diameter so first thing which I will do
6:12
is to project this radius i will click
6:15
on the project geometry and I will
6:17
project this and uh create a circle and
6:23
uh made it equal and uh we will create
6:27
one more
6:28
circle and uh the inside one is of a 30
6:32
mm here is a diameter 30 so I will
6:35
select smart dimension and give it a 30
6:40
so this is our sketch profile and uh now
6:43
we will extrude it to the distance of
6:47
120 because 105 + 15 is a 120 120 is a
6:52
total height which we can also see in a
6:54
side view so select the sketch click on
6:57
the pad and give the value 120
7:02
we are not seeing anything on the screen
7:04
because it is extruding in other
7:08
directions where there is a no material
7:11
so click on reverse so once you click on
7:13
reverse you will see it now we will say
7:19
okay now we will create this
7:23
cut whose detail we can see here so here
7:28
we will project this diameter 40 so we
7:30
will select this phase and click on the
7:33
sketch and
7:35
here we will press zero for right
7:38
orientation and we will set our model
7:40
like this and first thing we will do is
7:43
to project this uh radius uh we will
7:46
click on the project
7:48
geometry and we will create a
7:55
circle and uh we will make it
7:58
construction and now we will create a
8:00
threepoint
8:02
arc select a threepoint
8:06
arc and
8:09
here I will uh select a polyline tool
8:13
and close this
8:17
profile and now let's add the relevant
8:21
constraint for example this must be
8:24
horizontal
8:27
this should be also
8:29
horizontal so relevant constraint is
8:31
applied and now we wanted to remove the
8:33
material so we will keep this outside of
8:36
a body this line and uh we will make
8:40
this symmetric because our cut is of a
8:42
20 mm so I will select on a symmetricity
8:46
constraint select this point this point
8:49
and this axis and select a smart
8:52
dimension and uh provide it 20
8:56
mm and uh this dimension is
9:01
approximate so let's make it 50 and now
9:06
we will uh close it and we will select
9:09
the cut tool and we will say it through
9:13
all and say
9:16
okay now we will move to the next step
9:21
which is if you see in isometric view so
9:25
we will create this profile so for
9:31
this I will on the origin
9:35
plane and on origin plane we will select
9:39
this top plate and uh click on the DATM
9:42
plane
9:43
option expand it and create a DATM plane
9:47
and uh in a Z
9:50
directions we will provide a distance of
9:53
minus
9:57
11.5 so you can see that a datam plane
10:00
is created and now we will hide the
10:03
origin plane and here is a blue tick
10:06
symbol so we will write right click and
10:08
click on the recomp compute
10:10
object and now we will use this datam
10:14
plane to create this profile and here we
10:19
will use the single sketch but we will
10:23
do the two
10:24
extrusion so now I
10:27
will select the data plane and uh create
10:30
our
10:32
sketch and now here I will uh click on
10:36
the project geometry option
10:39
and I will project this radius and we
10:44
will switch to the wireframe
10:47
view and we will off this data plane and
10:52
now here I will use the threepoint
10:56
arc create one
11:00
arc select this and this and uh made it
11:04
equal and now I will create these two
11:09
horizontal line so select the line
11:16
tool draw the horizontal line and
11:20
now if you see here so this center to
11:24
this center distance is of 80 mm so here
11:28
is a radius of R25 and this is the 40 so
11:35
we will
11:36
uh create two
11:41
circle
11:43
and first thing which will be do we will
11:46
define this position 80 so we will
11:49
select smart dimension select this
11:51
origin to this and provide it 80 mm and
11:57
inner one is of a diameter 50 and outer
12:01
one is of diameter
12:05
80 and now here I can use the trim tool
12:10
and I can also use the coincidence tool
12:13
so here I will use the trim tool to
12:15
remove this geometry so
12:22
here
12:24
now we will
12:26
uh create a line and we will trim
12:30
this
12:31
so we will select a line tool and draw a
12:35
vertical line and select this line and
12:38
this point and add a coincidence
12:41
constraint and now let's click on the
12:45
trim and trim this half circle and also
12:49
trim this uh extra
12:52
line and
12:55
now this and this point is not merged so
12:58
I will select the both and uh add a
13:03
coincidence and now let's move this
13:07
dimensions to this
13:09
side and
13:12
uh so
13:14
here we will delete this line and uh we
13:18
will
13:21
uh draw the vertical
13:25
lines and
13:27
now let's see what is the
13:31
unconstrain so this is the unconstrain
13:34
so we will select this point and this
13:36
point and add a vertical line vertical
13:38
constraint and this and this and add a
13:42
vertical constraint so this is fully
13:43
constrained and now this line is not
13:46
horizontal so I will make it uh
13:49
horizontal so here we have the two
13:54
profiles but if you see here so we will
13:58
create one arc here to make this profile
14:04
independent
14:06
so what I will do I will select three
14:11
point arc and create one arc
14:15
here and select this and this and uh
14:19
made it equal so here is a one more arc
14:22
you will see and now let's come to the
14:25
out of the
14:27
sketch and now let's uh switch to the
14:31
flat lines
14:33
view and now we will switch to the top
14:36
view and uh we will create our extrusion
14:40
so we will first create this
14:43
extrusion whose thickness is of 11 mm
14:48
so I will press the control key and uh
14:52
select the
14:54
profile and now here there is a two
14:57
arc so we will zoom
15:00
it and we will select this arc
15:05
so this is the close profile I have
15:08
selected and uh now I will select the
15:11
sketch and click on the pad and here I
15:15
will make it 11
15:24
mm and now make it reverse
15:29
so here uh we have uh
15:32
created the datm plane so we will cross
15:35
check the dimensions of this datam
15:38
plane
15:41
so let's off this and from this to this
15:45
is of uh
15:48
11.5 but it should be 103 + 11 so
15:54
114 so we will edit the pad
15:58
and uncheck the
16:01
reverse and keep it symmetric to the
16:04
plane so now the total is of 120
16:09
mm so it should be 11 + 3
16:19
14 so this should be the 6 mm so that is
16:23
okay and now we will create one more
16:27
extrusion with the same
16:29
profile so here I will select this outer
16:33
radius inner radius and this two
16:37
vertical closing profile and click on
16:40
the pad and uh this is of a 15
16:46
mm and here I will click on symmetric to
16:50
the plane and uh say
16:54
okay now we will uh moves to the next
16:57
feature
16:59
next feature is to create a hole so here
17:04
I will uh select this phase and create a
17:06
cut
17:07
hole because it is a clearance hole but
17:11
uh you can also use this hole
17:14
feature so I will select the face and
17:17
click on the sketch and uh I will click
17:21
on the project geometry and project this
17:23
radius so that uh I will get a center
17:26
here
17:28
and now I will create a circle and give
17:33
the diameter of 12 mm and say
17:38
okay and now we will create a cut so
17:42
select the cut and I will select up to
17:45
face in
17:46
condition you can also set here through
17:49
all no issue because we do not have any
17:52
material here but uh my practice is to
17:56
limit the feature with respect to the
17:59
faces and
18:01
now we will
18:03
uh move to the next
18:06
feature which is if you see on a drawing
18:09
so here is a common fillet note of R2 so
18:14
we will provide a fillet of R2 so we
18:18
will click on the fillet and uh select
18:21
this age this one
18:24
this one so here is a face is selected
18:28
so we will remove it and we will zoom it
18:31
and select this edge similarly we will
18:34
select
18:35
this and
18:39
this and instead of two I will give
18:45
1.9 let's see what
18:47
happened so here is a issue so we will
18:51
check how much uh distance we have here
18:54
so here is a
18:56
two and here is also two so we will give
19:01
the fillet one by one we will press the
19:03
control key select this and this and
19:06
give the
19:08
fillet and here we will give the
19:13
1.9 and let's uh make it 1.99
19:21
okay and say
19:25
okay so uh the reason is that uh if we
19:30
give the round figure 2 mm then uh
19:33
radius age of this and this will get
19:36
merged which free does not allow that's
19:39
why we have given the
19:41
1.99 and uh same
19:44
way fillet is the most common issue in
19:46
free so we have to very carefully
19:50
understand how fillets works in freead
19:52
and now here I will give the one point
19:56
or here I can give the two because we
19:59
have the height
20:01
here say
20:03
okay so here let's uh give the
20:12
1.9 so here is a issue is there so we
20:17
will select the individual
20:19
edges and let's give the fillet of
20:26
1.9
20:28
okay so sometime it does not take the
20:30
two fillet combine so here is a 1.99 and
20:35
uh what if I do make it
20:38
two so it is working
20:42
similarly we will give the bottom
20:48
edge and
20:50
uh give it uh two
20:56
directly say
20:58
okay now press zero for
21:02
isometry so this is how we have
21:05
successfully modeled this part in a
21:08
freecad and you can see that our model
21:11
is a matching with the isometric view so
21:14
this is all about this tutorial and this
21:16
tutorial is designed for the beginner
21:18
user to understand the part design
21:21
workbench basic features like data plane
21:24
pad extrude cut fillet so this is uh all
21:28
about this tutorial
21:30
thank you for watching and thank you for
21:32
your valuable time
