welcome to fre tutorial and in this
0:02
tutorial we will model this uh gear
0:05
cover as you can see that uh I have
0:08
already model it and I will show you
0:11
from the scratch how you can model this
0:13
gear
0:15
cover so here I am using the
0:20
freead version 1.0
0:23
rc2 and I hope you have this free cat
0:27
version
0:28
1.0 if you have not it then um go to the
0:33
free.org install it so let's start our
0:37
tutorial I will uh close this file and
0:41
create a new
0:43
file so here I have created a new file
0:47
first thing which I will do is uh insert
0:50
body and I will on my origin
0:53
plane and uh we will read our drawing
0:56
and if you see our drawing so we will
1:00
create our first sketch on a right plane
1:03
so we will select this YZ plane and
1:05
click on the
1:10
sketch and we will go to the model Tab
1:13
and off the origin plane and now we will
1:17
uh select the polyline
1:19
tool so click on the polyline and uh we
1:23
will create a rough profile
1:33
so this is the rough
1:39
profile let me move my icons so that I
1:44
can get um more space now so this is the
1:49
115 so I will select this line and uh in
1:53
a freet 1.0 all Dimension are here
1:56
combined in a one so here I want
1:58
horizontal dimension
2:00
so I will give the horizontal Dimension
2:06
115 and uh vertical Dimension is also
2:12
115 you can directly click on here so
2:15
that free cat automatically detect
2:19
whether it is a vertical Dimension or
2:21
horizontal Dimension so give it
2:25
115 and this one is of uh
2:31
25 and we will give this
2:34
angle which is of
2:40
45 and
2:43
now here you can see that our sketch is
2:46
fully constrained so we will come out of
2:49
the
2:52
sketch go to the task and close
2:56
it now the next feature is to extrude
3:00
this
3:02
profile we will switch to the isometric
3:05
set the select the sketch click on
3:08
extrud and here we will give the value
3:12
130 and click on the symmetric to the
3:15
plane click on
3:20
okay and
3:23
now here is a fillet so we will give the
3:27
fillet of a
3:28
65 so I will uh select these two edges
3:32
by pressing the control key and click on
3:34
the fillet and here is a fillet of 65 so
3:39
we will give
3:43
64.99 and click on
3:48
okay and
3:51
now we will rotate our model and uh we
3:55
will uh remove the material because this
3:59
is the follow from the
4:01
inside so I will select this phase and
4:05
uh click on the shell
4:12
tool thickness and here I will provide
4:16
the thickness value of a
4:23
5mm and click on okay bottom
4:28
face and we will put project the
4:42
geometry let's switch to the flat lines
4:46
and now we have selected this outer phas
4:49
so we will click on this project
4:52
geometry select this age this
4:56
age this age
5:03
this H and this
5:07
H
5:11
now we will uh create a profile equal to
5:26
this select a three-point Arc
5:32
select this
5:33
point this point and this one click on
5:38
close go with
5:40
it and select up to pH and select this
5:44
phas and click on
5:48
okay so when I did the first time I was
5:51
I was seeing some pH here which was the
5:53
graphical issue
5:56
now press zero for uh isometric
6:00
and
6:01
here we will uh create a datm plane at a
6:05
distance of 5
6:07
mm so we will uh select this
6:11
pH and uh click on the datm
6:14
plane and in a z directions we will
6:18
provide the value of 5
6:21
mm click on
6:25
okay and on this phas we will uh create
6:30
this
6:32
tab now here is a Blue Tick so we will
6:36
rebuild it and select this datm plane
6:39
and click on the
6:41
sketch and we will go to the model Tab
6:44
and hide the datm
6:46
plane click on the project geometry and
6:50
project this
6:53
age switch to the flat lines and
6:58
here I will create a
7:01
rectangle we will delete this and select
7:05
three
7:09
point
7:11
and we will provide the
7:14
tangency
7:16
tangent
7:18
and
7:20
tangent and from here we will switch to
7:22
the wireframe and we will make this
7:27
symmetric so here is the symmetricity
7:29
constraint select this point this point
7:32
and this
7:35
axis and
7:37
uh from this point to this center point
7:42
we will provide the vertical
7:45
dimension of 70
7:52
mm we will move it and this
7:56
one is of uh 26
8:03
and this one is of uh
8:10
30 so here the dimension which is 70 I
8:15
given it is not from here it
8:19
is it is from the this
8:24
s so we will uh click on the project
8:27
geometry and project this
8:30
H and now I will select
8:34
this and
8:35
this
8:38
and provide the vertical dimension of a
8:41
70 mm
8:45
now from here we will switch to the flat
8:51
lines and uh we will create this
8:55
Extrusion which will be up to face of
8:58
this bottom bom one
9:02
so I will come out of the sketch select
9:06
the sketch click on next rot and from
9:10
here select up to face and we will
9:13
select
9:14
this bottom phas as our uh end
9:19
condition click on okay press
9:25
zero
9:27
now here is our hole so we will select
9:32
this phas and click on the sketch and
9:35
you can see that uh freeat set this
9:38
phase normal so we will uh click on this
9:41
project geometry and project this
9:45
age select the
9:50
circle and from
9:56
here select this point and this
10:01
point and provide the vertical
10:09
constraint edit
10:20
sketch and this is of uh 60
10:25
mm and
10:27
uh diameter of the
10:30
70 click on
10:34
close and we will switch to the flat
10:38
lines and we will remove the material
10:42
select the sketch click on exclude
10:48
cut click on okay we can also use the
10:51
through all no
10:54
issue and
10:56
now we will create this tab
11:00
here so we will select this bottom phase
11:03
and click on the
11:10
sketch switch to the
11:18
isometric you will project this
11:20
age click on the project geometry
11:29
rotate our
11:35
model and
11:38
now also click on Project geometry and
11:41
uh project this
11:43
age and here we will select a
11:46
three-point Arc create an equal Arc with
11:51
respect to our projected Arc
11:55
now create a line
12:01
and
12:03
uh this is
12:07
horizontal this is
12:09
horizontal select a three-point
12:14
Arc select this and
12:17
this and set a
12:21
tangent select this and this set a
12:26
tangent and this is of a diameter 26 so
12:30
we will prefer to give the radius which
12:33
is of
12:36
13 and we will select horizontal
12:40
Dimension select this and this and
12:43
provide the dimension of
12:50
82.5 now let's see what is the
12:53
unconstraint
12:59
so if you see that
13:02
uh this is the unconstraint because we
13:06
will make this
13:08
point and this
13:11
point will have the horizontal
13:14
relation click on
13:16
close and we will uh create a pad of uh
13:21
10
13:23
mm we are not seeing anything here so we
13:26
will click on reverse
13:29
and click on
13:32
okay and
13:35
now we will mirror this on the other
13:38
side so we will select this pad and
13:41
click on the
13:43
mirror and from here we will click
13:46
option of a select reference and we will
13:48
select this mid
13:51
plane and
13:53
here click on transform body and you can
13:57
see that our feature is got mirror we
14:00
will set
14:03
okay now press Z for isometric View and
14:07
now we will uh create a hole of
14:15
10.5 select the
14:17
face click on the sketch so here is a
14:20
10.5
14:22
drill so we will click on the project
14:26
geometry we can also make with a whole
14:28
feature but as it is a drill hole so I
14:32
will make uh with
14:34
the material removal
14:37
feature select a smart Dimension and
14:41
provide it
14:43
10.5 click on
14:46
okay select the skage click on extrude
14:51
code say it through all say
14:55
okay now select the face and click on
14:59
the
15:01
sketch click on Project geometry and
15:05
project this to
15:08
Arc select
15:18
circle
15:20
now select this and this and uh made it
15:25
equal select a smart Dimension and uh
15:30
give it uh
15:33
10.5 click on close select the sketch
15:36
click on extrude
15:39
Cut and from here say it through all say
15:48
okay and here is a common fillet of R3
15:52
which you can
15:54
provide on this age so I will select
15:58
this
15:59
this this this this Edge this one and
16:05
this hedge select
16:09
fillet it is uh
16:14
2.5 but uh we will queue it around to
16:17
three let's
16:20
see click on
16:23
okay you can provide the filler to the
16:26
inside like we have provided out website
16:30
so this is all about this tutorial how
16:32
to model this uh gear cover in
16:35
freeat thank you for watching and thank
16:38
you for your valuable time
