Hello friends Welcome To freecat
0:02
tutorial and in this tutorial we will
0:04
model lead screw bracket in freecat and
0:08
for this we are going to use the part
0:10
design
0:13
workbench you can also visit my website
0:16
Mech nexus.com where I write articles
0:19
and tutorials on freead you can download
0:23
my tutorial source file from the here if
0:27
you like my method of teaching then
0:29
please support me on coffee.com you can
0:33
buy me a cup of coffee your small
0:36
support will help this channels to grow
0:38
and it will motivate me to create more
0:41
awesome content on
0:43
fread I will provide my website and my
0:47
Kofi donation page Link in a video
0:50
descriptions so let's come back to our
0:52
tutorial so first I will switch to the
0:55
part
0:58
design and then I I create a new file
1:01
and I create a body and then create a
1:06
sketch so here uh first we will model
1:10
this base
1:12
plate so for this I will select this top
1:17
plane
1:20
XY and now we will read the dimension so
1:24
we can see that it is a 200 by 230
1:32
so I will select a rectangle
1:36
tool and uh create a
1:39
rectangle now I give the horizontal
1:43
Dimension 200 and uh vertical
1:47
Dimension
1:52
213 now I move my
1:56
dimensions and uh I will come out of the
2:06
sketch and I select my sketch click on
2:10
the
2:11
pad and this
2:14
uh
2:16
thickness thickness if you zoom it we
2:19
can see that it is a 25
2:22
mm I will give
2:25
the 25 mm
2:27
value and I will say okay
2:33
now we will uh create a
2:37
cut if you see the backside
2:43
view I will select this top
2:45
face and create a
2:48
sketch and for better
2:53
orientation I will switch to the
2:57
isometric now
3:03
I will create a
3:11
rectangle and I
3:13
will select this age and project
3:18
it now I will select this point and this
3:22
line and add the coincidence constraint
3:25
and
3:27
now we will give the dimension ion
3:31
so if you see the back view then
3:34
orientation will be like this so This
3:37
Dimension is a 38 if you zoom it we can
3:42
see here 38 and
3:44
102 so this
3:53
point I will switch to the part my like
3:57
this and select this line and this point
4:10
Point select this point and this
4:15
point it is a vertical
4:21
Dimension
4:24
102
4:26
and this point to this
4:30
point this is
4:34
horizontal select this point and this
4:38
point is
4:43
38 now I will switch to the isometric
4:47
view now I will close my
4:51
sketch click on the pocket
4:54
tool and material I will say through
4:58
all
5:26
now we will give the fillet so
5:30
here fillet Dimension is on the back
5:33
side which is uh not given but we will
5:38
if you zoom here we can see here it is a
5:43
45 because this age and this age is
5:46
matching
5:49
so I will select
5:52
the first I will remove the material and
5:55
say through all say okay now I will
6:00
select this
6:02
age and click on the fillet icon and I
6:06
will give my fillet
6:08
45 say okay now switch to the isometric
6:15
view
6:18
now we will
6:20
uh create this profile so for this I
6:24
will uh select the face and create a
6:28
sketch
6:32
and now I will project this
6:39
geometry this also and this
6:41
also and now I select the
6:46
line again select the
6:55
line and
6:58
now I will select the three-point
7:08
Arc
7:09
and and I will make
7:16
it
7:26
March now this uh
7:30
thickness is a 19 mm so I will give the
7:34
19 mm
7:39
Dimension and this outer one will be the
7:43
45 +
7:45
19 so select the
7:48
radius 45 +
7:54
19 and
7:58
now
8:09
now I will delete this line for time
8:21
being let's select the line
8:28
tool and I join it
8:32
again and from here we have
8:38
also create this type of a rib so for
8:42
this I will project the geometry select
8:44
the line
8:47
tool
8:50
again
8:54
now this is the 64 now we will move it
9:03
and I will add the tangency relation
9:09
here and I will merge these two points
9:13
say
9:15
merge so if you see
9:19
here there is also the tangency is
9:23
required so for this I will move my line
9:26
like this and uh create a line
9:30
and join it and then I will add the
9:33
tangential
9:36
relation
9:38
now we will give the
9:43
dimensions and before that we will uh
9:47
add here The Coincidence
9:53
relation and now the we will give the
9:57
position so first
9:59
I will select the vertical
10:02
Dimension give it 19
10:05
first select the horizontal
10:08
Dimension give the 19
10:12
here and now I will move
10:16
it I will also move
10:19
it now I will first close this
10:23
profile so first I will close from
10:28
here and
10:30
uh
10:40
here here is a conflict so I will delete
10:45
it again I select the line
10:50
tool join
10:52
it let's
10:55
uh remove the
10:58
conflict once I complete my profile now
11:01
I will select all
11:04
this and I will say
11:10
delete so here we can see from the
11:13
center this is
11:16
35 so I will uh select a
11:23
point and this point will
11:27
be what vertical Dimensions so 19 / by 2
11:34
and now I will give this point to this
11:36
point Dimensions
11:41
35
11:43
35 now we can see that
11:47
uh this is not coincidence so I will
11:51
make it
11:53
coincidence and I will merge these two
11:57
points
12:00
here it is not vertical so first make it
12:07
vertical say
12:09
merge and this will be the
12:13
horizontal and
12:15
now I will select these two points and
12:17
say
12:18
merge and this Arc and this
12:23
one will be
12:25
equal now I move my dimensions
12:30
now
12:31
here if you see it is 83 so we will
12:34
insert one point
12:39
here and give the
12:44
dimensions 19 / by
12:55
2 19 / 2
13:01
I move it and now we can see that here
13:04
is a dimension
13:07
83 so now I will select the horizontal
13:10
Dimension select these two
13:13
points and give 83
13:16
Dimensions so you can see that uh we
13:19
have fully constrained our sketch and
13:22
let me move the dimensions so that you
13:24
can clearly see
13:27
it
13:30
now I will close it and total height is
13:33
a
13:34
76 so I will click on the
13:37
pad and I will give the height
13:42
76 and
13:44
now we will create the two
13:49
cuts of the maximum diameter which we
13:54
have so for this first we will select
13:56
this one and and uh create a
14:01
sketch I will prefer to the isometric
14:04
View and now I will create a circle on
14:08
this
14:12
face of uh
14:18
diameter it is a given
14:23
70 now I will select this and give the
14:27
diameter dimension
14:29
of
14:37
70 and
14:39
uh the position the position will be at
14:43
this 35 from the age so I will project
14:47
this age and I will select these two
14:50
points and give the dimension of
14:56
35 and uh from the Center Height we will
15:00
uh find
15:03
it let's zoom into the
15:07
drawing so these both are the
15:27
70
15:31
so if you see in a side
15:36
view so we can see that it is a 102 is
15:41
given so both the centers are one2
15:48
distance so I will select this point and
15:52
this point and give the vertical
15:53
dimension of
15:57
102 now I will close
16:02
it if you want to see the dimensions I
16:05
move it outside so it is a 35 from the
16:08
age which is this one diameter is a 70
16:11
and height of vertical position we can
16:16
say is a
16:18
102 so
16:20
now I will close
16:23
it select my sketch click on the pocket
16:28
and from here I will say true
16:31
all we will do the same procedure here
16:35
we will select the face and uh create a
16:41
sketch and here I will create a
16:46
circle and I will give the diameter of
16:49
uh
16:52
70 I will switch to the front
16:57
view
17:01
and now I will
17:07
uh give the dimensions which is
17:16
83 83 and height is
17:27
102 I move my
17:30
Dimensions switch to the isometric view
17:33
I will close it I will select the sketch
17:37
and click on the pocket
17:39
tool and I will say simply through
17:44
all
17:47
now we will create this boss now so for
17:51
this we will again select this pH and
17:55
uh create a
17:57
sketch
17:59
and here we have already made the cut
18:02
feature so we will project the
18:11
geometry so in
18:13
our inner
18:15
board we will uh see in a drawing as
18:18
drawing is not much more
18:23
clear so we can see that uh R 2 HS
18:27
38.2 so we will take the maximum value
18:30
which is a
18:32
38.2 select on
18:34
diameter
18:38
38.2 now I will move my dimensions and I
18:42
will close
18:43
it select the sketch click on the pad
18:48
option and here we are not seeing
18:51
anything on a screen so we will click on
18:54
the
18:55
reverse and it is a distance of
19:01
51 and say
19:04
okay now we will do
19:07
the same
19:09
for this
19:12
type which we have created a cut here so
19:16
we will do the same procedure select the
19:18
face and create a
19:20
sketch and now we will project the
19:23
geometry so I will select
19:26
this age and we will get the center Mark
19:30
here now click on the circle
19:36
tools and again click on the
19:46
circle so we can see here it is a two
19:49
holes
19:51
means inside circle is the same for the
19:56
both so I will say select diameter
19:59
option
20:03
38.2 now I move my Dimensions I close
20:07
it select the sketch and click on the
20:10
pad and click on the
20:13
reverse and it is a 114 so do the
20:18
value and say
20:22
okay so we have uh created these two
20:26
boss and if we look from the back
20:31
side so you can see that our back view
20:34
is also
20:35
matching
20:38
now we will uh create this four
20:42
holes so we can see that uh here on the
20:46
back side there is a two holes here if
20:49
we look
20:51
at look at from this
20:55
directions so we are looking from this
20:57
direction
20:59
s now I will select the phas and uh
21:04
create a sketch so this is a plain drill
21:08
hole I will click on the sketch of a 19
21:13
mm drill I will uh create the two
21:20
circles and now we will uh see the
21:24
dimensions so here it is a 16 from the
21:27
age
21:29
so I will select it and give the
21:31
dimension of
21:39
16 and
21:43
uh this Dimension is a little bit not
21:50
clear so I will look it from the back
21:57
side
22:02
first I will switch to the
22:05
isometric and
22:08
then I will move to the right
22:10
orientations and click on the cube here
22:13
so this is 16 and I will select this
22:16
point and this
22:21
point select this point
22:26
and
22:31
so we will give the 19
22:44
mm 19 mm and this seems to be
22:49
38 so I will select this and
22:53
this
22:55
38 and I will make uh equal
22:59
relation say
23:07
equal and now I will give the drill size
23:11
of 19 so I will give diameter of 19
23:18
mm and I will add the
23:23
relation so
23:25
here this dimension 38 is not
23:30
clear but it seems like that uh it is a
23:34
symmetric from the both the
23:38
site so we will uh make it approximate
23:43
because this whole pitch is not clear
23:46
here
23:52
so I will make it uh
23:56
45 and this I make
23:59
25 so that it should look as per our
24:02
image now I will close
24:05
it and you have the both the
24:10
options
24:12
either either we can use the cut tool or
24:16
we can use the whole
24:17
tool so here we will use the whole
24:24
tool let I adjust my
24:30
in the center so here the it is a drill
24:33
of 19 mm so I will you my diameter
24:39
19 so you can see that two hole has been
24:42
created and now I will again switch to
24:44
the isometric view so you can see here
24:49
we are getting the perfect orientation
24:52
of a hole
24:53
here so that means our modeling approach
24:56
is a perfect and we are seeing an
25:00
isometric now we have the two more holes
25:04
here so for this I will again create a
25:07
sketch and here we will Zoom it so it is
25:11
a
25:12
19 first we will create a two Circle
25:18
randomly and now we will project the
25:22
geometry which we required to give this
25:24
Dimensions so it is a 19 and 38
25:29
so I will Zoom it and I will
25:36
give let's give this Dimension is a
25:42
32
25:47
32
25:49
vertical
25:55
19 and I will make the and this
25:59
equal select this point and this point
26:03
and make it
26:09
vertical vertical and uh distance
26:14
between Center to Center is a
26:16
38 so vertical Dimension is a
26:22
38 now it is a drill of 19 mm so give
26:28
the 19 mm now I move my Dimensions I
26:32
switch to the isometric
26:34
view so you can see that we have created
26:38
these two
26:42
holes
26:44
now we will come out of the sketch
26:49
and we will select the sketch and click
26:52
on the whole
26:54
tool and our drill size of 9 19 mm so I
26:58
will give the diameter 19
27:02
mm I close
27:06
it so you can see that uh we have
27:10
converted this isometric drawing of a
27:13
lead screw into the 3D model with the
27:16
help of a part design workbench and
27:20
now if you see
27:23
the common not is that fillet and rounds
27:27
are the R3 so which means that uh
27:31
everywhere we have to provide the fillet
27:33
of R3 so just select the
27:37
age for example this three ede and click
27:41
on the
27:50
fillet select this
27:56
h
27:58
just zoom it if you have a selection
28:01
problem click on the
28:05
fet and
28:07
now add more
28:21
fillet select the
28:26
edges
28:36
Zoom
28:43
it and click on
28:46
okay so you can see that uh we have
28:50
added the
28:52
fet so radius is a
28:55
R3 updated
28:58
it so this is how uh you can add the
29:01
fillet at uh all ages
29:06
available and here we will refine the
29:09
features select this
29:13
uh last features and here is in part
29:16
design refine is false click on the
29:20
true so you can see that uh ages got
29:23
merged like our parts so this is how we
29:27
have have successfully converted this
29:29
lead screw bracket into the 3D model
29:33
with the help of a part design workbench
29:36
so this is all about this tutorial I
29:38
hope you have enjoyed this tutorial
29:41
thank you for watching and thank you for
29:43
your valuable
29:47
