friends Welcome To frea tutorial and in
0:02
this tutorial we will model this part
0:04
from the scratch as you can see that uh
0:08
I have already modeled it and I will
0:11
show you from the scratch how you can
0:13
model this part as you can see that uh
0:16
my model in freecat it is exactly
0:19
matching with this isometric view I will
0:23
show you from the scratch how you can do
0:25
the same so for this
0:27
tutorial I am using the freead version
0:31
1.0 and this is the rc2 release I hope
0:35
you have installed the latest version of
0:37
uh freat version 1.0 with respect to
0:41
your operating system either you are
0:44
using Linux Mac or Windows OS and if
0:47
you're using the windows OS then I have
0:50
already made a video on my channel how
0:53
you can run freeat 1.0 on windows so I
0:58
will uh close this file and uh create a
1:01
new
1:05
file you can also visit my website Mech
1:08
nexus.com where I write articles and
1:11
tutorials on freead you can download my
1:15
tutorial source file from here tutorial
1:17
source file page and you can also
1:21
support me by buying a cup of coffee on
1:25
kofi.com your uh small support will help
1:29
this channels to grow and it will
1:31
motivate me to create more awesome
1:33
content on freead I thanks to all my
1:37
supporter those who have supported me by
1:40
buying a cup of
1:42
coffee so keep supporting and uh it will
1:47
help me to grow this Channel and it will
1:51
motivate me to create more awesome and
1:54
useful tutorials on freeat so let's come
1:57
back to our tutorial
2:00
so here I have created a new file and I
2:04
have activated my part design workbench
2:08
so first thing which I will do I will uh
2:10
create a
2:11
body
2:14
and now I will start
2:18
sketching we will also read our
2:23
drawing and uh we will do the
2:26
according so
2:28
here first thing which we will do is to
2:32
create a right profile and make a 360°
2:39
Revolution for this profile 8 mm
2:43
thick and uh diameter
2:47
is of uh outer diameter is of 80 mm so I
2:53
will uh on my origin plane and uh select
2:56
this right plane and click on the sketch
3:03
and now I will switch to the model Tab
3:05
and hide this plane so here I will
3:09
select a rectangle tool and uh create a
3:14
rectangle and we will uh select the
3:17
dimension
3:20
tool give the dimension 8
3:23
mm and uh here is a diameter 40
3:27
so select a dimension to tool select
3:30
this point and this point and
3:32
uh provide the dimension
3:36
40 and
3:38
now here we will provide the ID so if we
3:43
see our drawing side view here is a
3:45
diameter 18 is given which means
3:49
that radius will be the 9 mm so here I
3:53
will give the 9
3:57
mm so we have a fully constraint
4:01
sketch I will come out of the
4:03
sketch here is the icon leave sketch and
4:08
here we will uh click on
4:11
Revolution and here freead automatically
4:14
took the Z AIS but we
4:20
want in y
4:23
AIS and uh click on
4:26
okay so this is the base feature and uh
4:30
based on this base feature we will
4:31
create our rest of the
4:34
feature now let's study our drawing now
4:37
if you see the front view and this
4:40
isometric view so we can see here the
4:47
Extrusion so we will
4:49
create this line This Arc this line This
4:53
Arc and this
4:55
one
4:57
for our isometric view which we can see
5:00
here if you have a difficulty reading in
5:02
a
5:03
2d so now I will select this pH and
5:07
click on the
5:09
sketch I will switch to the isometric
5:12
and switch to the
5:13
front and from here we will switch to
5:16
the flat lines so here if you see that
5:19
here is the diameter of a
5:23
62 and this is the tangent on the
5:27
diameter but this diameter will be the
5:29
construction
5:31
one so here I will uh switch to the wire
5:36
frame and uh select this and make it
5:41
construction select diameter and uh
5:45
provide the diameter of a
5:48
62 and uh we will also project this uh
5:51
inner diameter click on the project
5:54
geometry and
5:57
uh create a circle
6:00
select this and this and uh made it
6:04
equal and now we will uh project this
6:08
outer
6:09
diameter click on Project geometry and
6:12
project this outer diameter and
6:16
now we will create a
6:22
line angular line
6:26
here here and one line
6:30
at here so here basically we have create
6:33
this one this one and this one and if
6:36
you want to see in isometric so this is
6:39
this one this one and this one so our
6:42
whole idea is to create this profile and
6:45
exr to this distance which is of 12 mm
6:49
because if you minus 8 from the 20 this
6:52
is the 12
6:53
mm
6:57
now now we will uh
7:00
provide the angle so here the angle is
7:05
given
7:06
60° which we can see here so we will
7:09
select this and this and uh give the
7:15
60° select this and
7:18
this and give the
7:25
60° and now I will uh move this
7:30
angle
7:36
Dimension and here we will select this
7:40
and this and uh add a
7:45
tangency so we will move to the outside
7:49
of a diameter and then we will provide
7:51
the
7:52
tangency similarly here we will move it
7:55
to the outside select uh this and
8:00
this and this and add a
8:04
tangency same way here we will select
8:07
this and this and add a
8:11
tangency now we will create a
8:14
three-point
8:17
Arc so here we will go the arc by
8:21
3o select this point this point and here
8:26
we will select this and our construction
8:29
Di
8:30
and give here equal
8:32
constraint similar way we will create
8:35
here 3point
8:37
Arc select threep Point
8:42
Arc and
8:47
here select this and this and apply the
8:51
equal
8:52
constraint again select a three-point AR
8:55
so here is a shortcut also given
9:05
so my advice is rather than making it
9:08
equal make it unequal and then apply the
9:12
equal
9:14
constraint so our uh sketch is fully
9:17
constrained we will come out of
9:19
it and from here we will switch to the
9:22
flat
9:25
lines and now we will uh create
9:27
Extrusion of 12 mm so select the sketch
9:31
click on
9:32
extrude and uh provide the distance 12
9:35
mm click on okay now if you see our
9:39
isometric view we have made this Revol
9:42
profile and we have created this boss
9:45
now let's uh create a new feature and
9:49
now our next feature is to create a cut
9:53
at three locations so we will create one
9:56
and then we will make the polar pattern
9:59
so we will select the phase and click on
10:01
the sketch and set our model to the
10:04
right
10:05
orientation and switch to the flat
10:09
lines now here uh we will switch to the
10:15
wireframe so now let's uh read the
10:17
drawing so this is the at angle of 30°
10:21
and this is the R6 so first thing we
10:24
will do we will uh create a line and uh
10:29
we will make it a
10:31
construction and provide the 30°
10:38
angle and uh we will click on the
10:41
project
10:43
geometry and uh next thing is we will
10:46
use the trim tool to trim
10:48
it and
10:50
now here I will uh create a
10:55
circle and uh
11:00
we will use the radius constraint and
11:02
provide it
11:05
six and
11:06
now we will use the trim
11:09
tool and now we will uh close this
11:16
profile we will close
11:19
it and from here we will switch to the
11:23
flat lines first we switch to the Shaded
11:26
and then switch to the flat lines
11:31
now we will select the sketch and click
11:33
on extrude
11:35
COD and say reverse so nothing is
11:39
showing which means that there is a
11:42
problem with our
11:45
sketch so we will validate our sketch
11:48
select the sketch and click on this
11:51
validate sketch and
11:53
uh click on highlight troubleshoot vtex
11:58
so we can see here here two Vex are
12:00
highlighted here so we will close it we
12:04
will edit our
12:06
sketch we will delete it so we will
12:11
create a
12:15
line
12:18
and we will select this point and this
12:22
point and make it
12:24
coincidence select this point and this
12:28
point and make it coincidence
12:31
now we will select the sketch click on
12:33
the
12:35
cut now we will extrude it to the this
12:41
phase this phase here so we will set our
12:44
in condition set up to phase and select
12:47
this phas and click on okay now we will
12:52
uh select our cut and click on the Polar
12:56
pattern and from the axis we will choose
13:00
the Y
13:01
AIS and uh number of quantity we will
13:05
set three so you can see that this cut
13:09
got pattern at three
13:11
locations click on okay
13:15
now we will uh create our next
13:18
feature which is this
13:22
cut this one so we will again select the
13:26
phase and click on the
13:28
sketch switch to the
13:31
isometric switch to the front view and
13:34
click on the
13:35
circle and here I will uh select it and
13:41
uh provide the diameter
13:46
40 which we can see
13:50
here give the 40 and uh now we will
13:54
remove the material to the distance of
13:57
10 mm
14:00
select
14:01
cut and provide the cut depth 10 mm
14:06
click on okay now we will move towards
14:09
the next feature so next feature is to
14:14
create this cut at three locations so
14:17
for this we have to create a tangent
14:22
plane so to create a tangent plane we
14:25
can create a tangent plane or we can
14:28
simp simply create a a datm plane at a
14:33
distance of 40 mm because our diameter
14:36
is 80 so when we on our origin plane and
14:40
if you select this plane and create a
14:43
plane at a distance of a 4 so it will
14:47
automatically tangent to this outer
14:49
surface so we will click on the datam
14:52
plane and in a z directions I will
14:55
provide the 40
14:56
mm so you can see that it is perfect
14:59
tangent we will say okay and
15:03
now we will uh off our origin plane and
15:06
we will select this datam
15:08
plane and before that here is a tick
15:12
mark is showing which means that uh we
15:14
have to rebuild our model now select the
15:18
data plane and click on the
15:20
sketch and for better sketching press
15:23
the space bar to hide this dat temp
15:27
plane and now
15:29
we will uh
15:31
create the cut profile which is given
15:35
here
15:36
so first thing which we will do is to
15:40
project this edges and
15:44
now we will create a
15:47
line so we can see that it is a 16 mm so
15:50
we will use the symmetricity constraint
15:53
select this point this point and this
15:56
axis select smart dimension
16:00
and uh provide the 16
16:06
mm and
16:09
now I will draw the two vertical
16:13
line one this side and one this
16:18
side and this is of a distance of a
16:21
2.5 so I will uh give the distance here
16:27
2.5 select
16:30
this this line and this line and uh made
16:33
it equal and
16:36
now I will draw the two horizontal
16:39
line let's move it
16:42
inside and for better visibility I will
16:45
switch to the wireframe so that you can
16:47
clearly see it what I am sketching now I
16:50
will draw the two horizontal line at
16:52
both the
16:54
side and uh I will provide this symmetri
16:58
constraint
16:59
so use the symmetricity constraint
17:01
select this point this point and this
17:05
axis select Dimension select this point
17:09
and this point and this will be the 18
17:12
mm which we can see
17:14
here and
17:17
now here it is a 3 mm two vertical
17:21
lines so select a line
17:24
tool draw the vertical line
17:29
and make it
17:31
vertical select smart
17:34
Dimension give this one 3
17:37
mm select this and this and provide it
17:43
equal and now here is a 12 mm which
17:47
means that we draw a two horizontal
17:50
line select a line
17:53
tool create one horizontal line and
17:56
second horizontal line so this is not
17:58
horizontal make it
18:00
horizontal and let's uh close our
18:10
profile and make it
18:13
vertical so now here it is a 12 mm so we
18:16
will make this
18:18
symmetric so click on the symmetricity
18:21
select this and this and this
18:25
axis and select smart Dimension and Prov
18:30
it 12
18:36
mm and uh total is of uh 9 mm so we will
18:41
select this and this and uh give it a 9
18:48
mm so this is the
18:52
cut profile now we will come out of the
18:56
sketch and now we will uh
18:59
create a cut and before that we will
19:02
switch our model to the isometric View
19:05
and let's switch to the flat line as
19:07
well so here is a bug if I am clicking
19:11
on the flat lines it is not getting flat
19:14
lines view so first we will switch to
19:16
the Shaded View and then again switch to
19:18
the flat lines
19:21
now select the sketch click on extrude
19:24
Cut and uh provide a distance of 30 mm
19:29
so this 30 mm distance is approximate so
19:32
that it open here no material is
19:37
there click on okay and now we will
19:42
polar pattern it at three locations with
19:46
respect to our isometric image so select
19:49
the pocket and click on the Polar
19:53
pattern and occurrences is
19:57
three and and we will select y
20:03
AIS so you can see that it got polar
20:06
pattern at relocation click on okay and
20:09
now let's uh move to the next feature
20:14
which is to create this
20:16
hole at three
20:19
locations so we will select the
20:22
face and uh click on the
20:25
sketch switch to the isometric
20:31
switch to the flat lines and now here
20:35
instead of doing the polar pattern we
20:37
will directly create a hole at a three
20:40
location of diameter
20:45
8
20:47
now we will uh switch to the wireframe
20:50
view here and project this three
20:53
Arc click on the project geometry select
20:57
this this and this
20:59
and create a circle at three locations
21:02
you can also use the polar pattern no
21:09
issue now select the
21:12
diameter and uh provide the 8 mm and now
21:17
I will uh select uh all three circles
21:22
this
21:24
one this one and this one and and apply
21:29
the equal
21:31
constraint close the
21:37
sketch and now we will uh create a cut
21:41
at a three locations as it is
21:44
a drill hole of M8
21:48
so if you see
21:51
here so it is M8 hole so we will use the
21:54
whole wizard tool to create this hole so
21:58
here we will select the whole
22:00
Wizard and from here we will select
22:03
isometric regular profile and from the
22:06
sizes here we will select the 8 mm and
22:09
the distance we will select the through
22:14
wall and it is the
22:20
threaded so hold depth and here is a
22:23
thread
22:26
class click on okay
22:32
and let's create a next
22:35
feature which is this one these three
22:38
holes which is of a size
22:41
M5 so we will select this interface and
22:45
uh click on the
22:47
sketch set our model to the right
22:50
orientation and select the front view
22:53
and here first we'll create a
22:56
construction diameter of a 20 8 select
22:59
the circle and uh create a construction
23:02
diameter of a 28 select smart
23:06
Dimension provide the
23:08
28 and uh never forget to make this
23:12
construction because it is a PCD Circle
23:15
and here we can see that uh this M5 hole
23:18
has a 30° so we will uh again create a
23:24
line and select smart dimension
23:29
and give it angle of
23:35
30 and this will also be the
23:39
construction and uh click on the trim
23:42
and uh trim the extra geometry here now
23:47
we have got the point here we will
23:50
select a
23:51
circle and give it a dimension of 5 mm
24:00
now click on
24:02
okay press zero for isometric select the
24:05
sketch click on the
24:07
ho and from here we will select
24:10
isometric regular profile size we will
24:14
give the
24:15
M5 and it is a through
24:19
all so clearance is standard we do not
24:23
go much in uh This Thread class click on
24:26
okay
24:28
now we will uh polar pattern this whole
24:32
so click on the Polar
24:36
pattern and uh occurrences we want
24:42
three and here we will select the Y
24:46
AIS and click on
24:48
okay so you can see that this hole is
24:51
got pattern now let's uh move towards
24:55
the next feature
24:58
which is again to create a hole of M6 at
25:02
three
25:04
locations so we will now select this
25:07
phas and uh click on the
25:11
sketch press zero for isometric and
25:14
switch to the front select the
25:18
circle and create a circle so this is
25:21
the PCD Circle so we will make it a
25:24
construction and select Dimension option
25:27
and uh provide the dimension of uh 60
25:32
mm and
25:34
now we will uh create a
25:38
circle which is of a size of M6 so
25:42
simply uh give here the
25:45
6mm and uh now I will select this and
25:48
this PCD Circle and provide the
25:51
coincidence
25:52
constraint click on close and now we
25:56
will create a M6 hole through
25:59
so select the whole
26:01
tool
26:04
and as uh we have it for previous ho
26:08
select isometric regular profile here is
26:11
a size select m6 and distance through
26:15
allall click on okay now we will also
26:19
polar pattern it select the ho and click
26:23
on the Polar
26:24
pattern and as usual we will select the
26:27
y axis
26:28
is our axis of
26:30
rotations and du the occurrences three
26:35
so you can see that this has been
26:37
updated at three locations click on
26:42
okay now now we will provide the chamfer
26:46
so if we go to our drawing so at this
26:50
hole we have the chamfer of for 1 to 45
26:54
so I will press the control key and
26:57
select all three edges and click on the
27:01
chamfer and here is the 1 mm click on
27:04
okay so chamfer is
27:07
applied
27:09
now let's uh do the chamfer at here as
27:13
well if you see the isometric view here
27:17
is a chamfer of 1 mm so I will select
27:20
this
27:21
H and this
27:24
age and click on the cham for
27:29
and give the 1 mm so
27:32
basically role of the chamfer here is
27:35
that it is the entry chamfer because it
27:38
is a circular profile so some shaft will
27:42
go to the inside so that's why this uh
27:44
entry chamfer is
27:47
provided
27:49
now this completes our
27:52
model and you can see that uh I have
27:55
shown you from the scratch how you can
27:57
uh model this part from the scratch and
28:00
this is all about this tutorial thank
28:02
