Hello friends welcome to fre tutorial
0:03
and in this tutorial we will learn
0:06
sketching in
0:08
freead in this tutorial we will learn
0:11
how to read a drawing sketch and uh how
0:16
to start because starting is a very
0:19
important while creating any part sketch
0:23
if you read the dimension correctly then
0:25
you can save your lots of time but if
0:29
you just start by seeing the sketch not
0:33
study it properly then it will take lots
0:36
of time to create an sketch so mastering
0:40
the sketch in a freead is a must have
0:43
things if you want to design the part
0:46
within a less span of a
0:49
time you can also visit my website Mech
0:52
nexus.com where I write articles and
0:56
tutorials on freead you can download my
0:59
my tutorial source file from the here if
1:03
you like my method of teaching then
1:05
please support me on coffee.com you can
1:09
buy me a cup of coffee your small
1:12
support will help these channels to grow
1:14
and it will motivate me to create more
1:17
awesome content on
1:19
fread I will provide my website and my
1:23
Kofi donation page Link in a video
1:26
descriptions so let's come back to our
1:28
tutorial so here I'm not going to use
1:32
the Sketcher workbench I'm going to use
1:35
the part design workbench
1:38
because it is very easy to create a part
1:43
but in this tutorial our scope of
1:46
learning is to the master the sketching
1:48
in
1:49
freead so here I will uh activate my
1:53
part design and I create a new file and
1:56
create a body and create a sketch I will
1:59
select this this exit
2:01
plane and now we will read our drawing
2:06
so we can see that here is the ellipse
2:09
portion is
2:11
here which we are not going to cover
2:14
because we are not going to make the 3D
2:16
model we will draw this profile and how
2:19
we can draw it in Optimum way with a
2:23
less time consumption so if it start
2:28
from the right hand side then we we can
2:30
see here we have the different radius
2:33
like R34
2:35
R50 and here is a
2:39
r64 so we have the three radius if you
2:42
try from here then it will take time so
2:46
why not start from the left hand side
2:49
and draw the sketching from left to
2:53
right if we draw from the left hand side
2:56
then we can see
2:58
here we we have the dimensions 32 if we
3:02
draw from here then we will get this
3:05
radius 64 which means that we will get
3:09
one point
3:11
here and then merging this r64 R50 and
3:17
R30 will be much
3:19
easier so our Center will be the
3:24
our part Center here spanner Center so
3:29
we will see here the dimension given
3:32
305 and here is a
3:35
R32 so we will simply create a
3:40
circle and select this point and this
3:44
point and provide horizontal
3:48
relation now I will go with the diameter
3:52
dimensions and I will give it
3:55
uh
3:58
64
4:01
and I will make it as a construction
4:05
geometry now I will draw the two
4:12
lines and add the tangency
4:19
relations again add the tangency
4:23
relation
4:25
now I will trim the geometry which are
4:28
not required
4:31
now I will select a three-point
4:36
T and draw the
4:39
approximate
4:41
now we have the two options either we
4:44
can give the tangency or we can give the
4:47
equality I will give the
4:50
tangency so you can see that both the
4:52
tangents added here
4:58
now the we will again select a
5:00
three-point
5:04
AR on both the
5:07
side and in this case I will make these
5:11
two
5:15
equal and select this point and this Arc
5:19
and add the tangency
5:21
relations similarly we will do
5:25
here and I will give the radius
5:30
Dimensions
5:42
64
5:46
now we will give this 305 Dimensions
5:49
from this Center to this
5:53
Center give it
5:58
305
6:00
and I move it
6:08
down and now we can see
6:12
here this is the
6:15
unconstraint so we will move it here
6:19
because this Center Point is not
6:22
defined but it will be get defined once
6:25
we create this
6:28
profile so let's go ahead so here we can
6:32
see that radius
6:34
R32 so we will again create a 3point
6:40
Arc
6:42
and one 3point arc on the other
6:46
side and I will make this and this
6:52
equal add the tangency
6:57
relation similarly here
7:02
and
7:04
now we have the center
7:07
here now I will select a
7:12
line and I will make it
7:16
construction and I will add The
7:18
Coincidence
7:21
relation and I will click on angular
7:27
Dimension so this is a 15 de which uh we
7:30
can see here so I will give 180 minus
7:37
15 so it will be
7:40
165
7:42
now here is a width is a
7:45
38 so I will select the
7:48
line draw the two
7:53
lines now these two lines will be
7:58
parallel similarly this and this
8:04
parallel and
8:08
now I will add The Coincidence relation
8:12
here similarly here as
8:19
well and now I will uh trim the
8:22
unnecessary
8:27
geometry this and this
8:30
this and now I will select this I will
8:34
select symmetricity
8:36
constraint select this
8:38
point this point and our construction
8:43
geometry now give the dimension of a
8:55
38 and here is a R22 so we will select
9:00
the
9:06
circle give it a diameter dimension of
9:14
44 and now we will again trim the
9:18
unnecessary
9:28
geometry
9:36
so this will be the our inner
9:50
profile
9:51
now let's give the dimension which is
9:54
the
9:58
R34
10:07
now we will move
10:18
it and now here is a R50 so I will
10:25
select this point
10:28
and this
10:33
point and give the radius of
10:36
uh
10:42
R50 and
10:44
here I will add the tangency
10:55
relation select this Arc and this Arc
10:58
and add the
11:07
tangent this and this is
11:10
equal so now you can see that we have
11:13
still degree of freedom
11:15
because this point and this Center
11:19
Point is not
11:22
merge it is not merging because we have
11:25
given the dimension
11:27
now we will say this two and say
11:32
merge now I will give the radius
11:35
dimension of
11:54
50 so you can see that
11:56
uh this is also not much merch so we
11:59
will click on it and say
12:09
merch so
12:13
here this Center points and this Center
12:17
points will be the
12:25
vertical and
12:27
here we will also at the tangency
12:35
relation and
12:56
now this is R35
13:05
4 and now here we
13:13
will we will see here R34 Center is not
13:17
defined so we will keep as it is and now
13:21
this two points
13:27
positions we will
13:29
fix it by creating a
13:32
line let's join these two lines and uh
13:35
make it
13:36
construction and let's use some
13:40
Dimension to lock its angular moment
13:43
let's say
13:46
15° and now if we try to
13:54
move so it is not
13:56
moving and now we will will again select
13:59
a three-point
14:06
Arc add the tangency
14:09
relation so here is something is
14:11
overdefined which we will find here and
14:14
we will delete
14:24
it so
14:27
here
14:29
this Center our existing Center and this
14:33
Center will be the
14:36
vertical
14:40
now here this position is
14:48
a here we we can see that there is no
14:51
any tangency relation so what we will do
14:53
we will just simply select this point
14:55
and line and make it coincidence const
14:59
screen now we will move our Dimension to
15:02
the outside and come out of the
15:08
sketch so
15:11
here here we can see that it is not as
15:14
per our sketch so we will again go to
15:17
the
15:18
sketch and
15:20
uh delete this
15:26
constra and uh we will give some
15:30
horizontal
15:31
Dimensions to fix
15:35
it let's see 3
15:42
mm or say 1
15:54
mm on Q2 mm so it looks like a
15:59
approximately now we will come out of
16:01
the sketch so that is how we have uh
16:07
created the sketch of a spanner in
16:10
freead and you can see that uh this is a
16:15
very logical how to create a sketch with
16:18
a
16:20
less time consumption if we have a
16:23
started from the right hand side then it
16:25
might take a longer time but we we have
16:29
did the sketching and we have a fully
16:31
constrained it with the help of
16:35
uh available constraint in freead but if
16:38
we have tried it from the right hand
16:41
side then it was very difficult to match
16:43
it so it is better to always try from
16:47
the easiest
16:50
side so more or less we have created the
16:53
sketch of a spanner in freead I hope you
16:56
have enjoyed the sketching in
16:59
sketching in free cand I hope you have
