Hello friends welcome to Free care
0:02
tutorial and in this tutorial we will
0:06
model this sheet metal part in a free
0:09
card with the help of a sheet metal
0:11
workbench and I will show you from the
0:13
scratch how you can do it in freead you

description so first I I will create a
1:01
new file and uh I will create a
1:04
body and before starting the tutorials
1:07
we will read our drawing so if you are
1:10
feeling difficulty to see the dimensions
1:13
then do not worry I will provide the
1:15
source file and 3D model in the video
1:18
descriptions so
1:20
here we will read our drawing so first
1:23
we will make this base
1:25
flange and and we will build our feature
1:30
from bottom to
1:33
top and at the last we will make this
1:37
hole so let's start so I will create on
1:42
the sketch and I will switch to the
1:44
autographic and then isometric and I
1:48
will select this top
1:50
plane and uh I will draw a
1:56
rectangle and I will switch to the is
2:00
ometric so as per our part
2:04
orientation this is our side
2:07
view and this will be our front view so
2:11
according to that we will give our
2:17
Dimensions so I will click on the
2:21
dimensions and I will give it
2:25
48 and this one is a 56
2:33
now I will move to the top and I will
2:37
make it
2:38
symetric so I will select this
2:41
point this point and the center
2:45
point and I will come out of the sketch
2:48
so this is the our base sketch now we
2:51
will switch to the sheet metal
2:57
workbench and we will go to the tree
2:59
View and and select our
3:02
sketch and we will click on make base
3:07
wall now our base feature has been
3:10
created if you want to see it property
3:13
then click on the features and go to the
3:15
property view then you will see that uh
3:18
the radius and thickness of our base
3:21
feature
3:23
now we will make this flange one at a
3:27
left hand side and other on the right
3:29
hand side
3:30
so this uh flange length is a 78 mm so
3:34
we will select this H and this H and
3:38
click on the
3:41
flange now you can see that uh its
3:45
direction is the opposite what we requir
3:49
so click on the bend go to the property
3:53
manager and in property manager you will
3:56
see an option of invert here so you can
4:00
see that invert is false so just click
4:03
on the
4:05
true so you can see
4:08
that flange has been reversed but we
4:12
want our flange length at a
4:14
78 so click on the flange go to the
4:17
property view click on the data and here
4:21
you will see the length is a 10 mm so I
4:24
will change it to the 78 and click on
4:28
the graphical area so you can see that
4:32
flange has been
4:33
modified now we want to create one more
4:37
flange at
4:41
this so which is
4:43
the radius is given the r six so we will
4:47
change the radius
4:51
later so we will give the 6 mm flange so
4:54
I will select this one and this one H
4:58
and click on the
5:00
make
5:01
wall so it has been in opposite
5:04
directions so we will repeat the same
5:07
procedure click on the bend go to the
5:09
property click on the data
5:14
and go to the
5:17
invert and make it
5:24
true so flange length we want 6
5:28
mm so I will go to the
5:31
length and give here 6
5:36
mm so before that we will go to the our
5:41
first
5:43
feature and go to the property and then
5:48
data and here radius we will make it 6
5:52
mm because as for our drawing it is a 6
5:57
mm now
6:00
go to
6:02
the second Bend go to the property and
6:05
let's
6:06
check radius is 1
6:09
mm give the
6:14
six on
6:20
it go to
6:22
the third one go to the property and
6:27
data and radi is 6
6:40
mm so in this
6:44
case radius is a 6 mm from the outside
6:49
but our sheet metal thickness is a 4 mm
6:53
which we have
6:56
not concluded uh while we
7:00
starting but as free is a parametric
7:03
part so do not worry so we will go to
7:05
the our base features and uh click on
7:10
the thickness and give it 4 mm so if our
7:14
outer radius is a
7:18
6+ 4 so our sheet
7:23
metal thickness is a 4 mm outside is a
7:28
R6
7:31
so
7:34
inside inside radius would
7:40
be 2
7:42
mm so we will go to the our base
7:46
features go to the property and data and
7:49
we will give 2
7:53
mm
7:55
now we will on our second Bend go to the
8:00
property data and radius we will give
8:03
the 2
8:09
mm on it and then third bend on it and
8:14
uh go to the
8:18
property and
8:20
uh radius
8:25
here Give It 2 mm
8:32
okay so now we will go to do our preview
8:37
select this H and this H and we will
8:43
give our flange
8:45
length click on the flange and select on
8:50
the bend go to the property and then
8:53
data
8:55
and say inot true
9:02
so total height is uh
9:06
117 +
9:08
15 so it is a 132 Total
9:12
1 so 132 -
9:18
78 so we will go to the
9:21
flange go to the length and here we
9:26
can give 13 2 -
9:35
78 so here we have got our final
9:40
height now we have uh
9:44
made this
9:47
shape as per our
9:52
drawing now we
9:56
will remove the material so so for the
9:59
material removal we will switch to the
10:02
part design workbench select the ph and
10:05
create on the
10:08
sketch
10:11
now we will project this
10:18
age project this age and
10:25
then I will draw a line
10:30
so as this uh at this point is not given
10:33
in a drawing so we will uh take it
10:39
approximately and uh now I will uh
10:43
project this age
10:46
also and I will select threo
10:51
Arc and I will draw the three-point AR
10:55
and I will make the tangent
11:00
and I will also make it the
11:06
tangent and this uh Arc position is a 15
11:11
mm from The Edge so I will select this
11:14
Edge and I will
11:17
select this
11:19
point this
11:21
point and I will give the horizontal
11:24
dimension of 15
11:27
mm
11:31
and now I will fix the position so I
11:35
will select this point and this point
11:38
and give my vertical
11:39
Dimension I would give approximate 50
11:48
mm and then I will give my
11:52
angle so I will give select here angular
11:55
and I
11:56
will give dimension
12:02
say
12:08
155 say
12:11
170 or
12:19
165 now I will uh Tri
12:24
it and uh I will close the profile
12:33
so instead of this
12:38
Arc I will uh create a circle which will
12:42
be tangent to this two
12:44
line as we see our
12:47
image so I will delete it and I
12:52
will create a
12:55
circle and I will make it a tangent
13:02
okay and I will also select this line
13:05
and this circle and I will make the
13:08
tangent and I will select this and this
13:11
and I will make the
13:15
tangent but we will make this circle as
13:18
a
13:20
construction and now we will remove this
13:23
unnecessary
13:25
geometry and now we have the point here
13:29
so I will simply draw a three-point
13:35
AR and I will make this and this
13:40
equal and let's see what is the
13:50
unconstraint I will select this and this
13:53
and I will make the tangent okay now all
13:56
we have to close the profile and remove
13:58
move the
14:00
material so I will select the line I
14:03
will join this point and this
14:06
point and this and this point now we are
14:11
seeing some conflict here so I will
14:13
simply delete the
14:15
dimension what is the
14:17
conflicting so this constraint
14:20
13 and uh now I
14:25
will close
14:27
it and I will go with a
14:32
cut and I will simply say through
14:36
all and I will say
14:38
okay so now we will see our
14:44
model so somewhat we have achieved our
14:48
profile
14:49
now we have to remove the
14:53
material at uh this portion we want to
14:57
cut this material
15:00
so for this we
15:02
will select the face better to select
15:05
the outer face this one and uh click on
15:10
the
15:11
sketch and I will project this
15:17
Arc and
15:19
now I will uh
15:23
simply project this to H or I
15:27
simply draw a circle that would be much
15:32
easier now I
15:35
will make this
15:38
construction now I will project the
15:40
H now I will select the three-point
15:49
T and now I will make it
15:56
tangent first I will make it
16:01
equal and this point is UNC
16:05
unconstrained so simply I can make it
16:08
this two point
16:10
horizontal now we have to remove the
16:12
material so we will close the
16:21
profile now here some dimension on the
16:24
conflicting
16:27
so
16:39
I will make this and this
16:46
vertical okay
16:51
so better I will delete the
16:55
circle I will merge it
17:03
merge it and I
17:05
will
17:13
project and I will make it
17:20
coincidence all constraint has been
17:23
broken I don't know
17:27
why
17:30
so now we have again constrained it now
17:33
we will close the
17:35
sketch and simply go with the extrude
17:39
cut and I will say through all I will
17:43
say okay so you can see that uh cut has
17:47
been
17:49
adapted
17:51
now we
17:53
will make this diameter 30 cut on our
17:57
base feature
17:59
here so better I will
18:03
select top pH or bottom phas in this
18:06
case no problem so I will select this
18:08
top face and I will create a
18:11
sketch as our part is symmetric so I
18:14
will
18:17
select the origin point and draw a
18:20
circle and now I will give it
18:23
a diameter
18:26
30 I will close it
18:30
then go with a
18:32
cut and I will simply say through
18:40
all now we have to make this counter
18:45
board
18:48
holes so for this uh I think uh we can
18:53
go with a counter board or we can go
18:56
with a simple cut so I will select the
19:00
face and I will create a
19:03
sketch so here I will not use the whole
19:07
feature I will simply use the cut
19:09
operation so I will project the
19:13
H I will uh draw a
19:17
circle the OD is at 20 so I will select
19:22
this and I will give the
19:27
20
19:31
and is a depth is a
19:34
1.5 so I will close
19:37
it go with a
19:39
cut and I will give it
19:43
1.5 and
19:46
then inside diameter is a 14 so select
19:49
this pH and I will create a
19:52
sketch
19:54
sorry I will uh select this pH create a
19:59
sketch I will project the
20:04
circle
20:06
and draw a circle of
20:10
uh diameter 14 so I will select this and
20:15
give the diameter
20:17
14 and I will close
20:20
it and I will go with a
20:24
cut and I will say it to
20:29
face and I will say okay so why I have
20:33
not used the whole features because it
20:36
is a very simple type of a
20:40
hole and now I will mirror this pocket 3
20:45
and
20:47
four so for this I will click on this
20:49
mirror
20:51
command I will select pocket three and
20:54
four click on
20:56
okay and as we have made our part
21:00
symmetric so we will mirror it with
21:03
respect to the exit plane so here I will
21:05
select exit
21:08
plane so you can see
21:12
that mirror feature
21:15
created now I will switch to the
21:23
isometric so as you can see that we have
21:27
a successfully converted this sheet
21:31
metal
21:33
drawing into the 3D model with the help
21:36
of a sheet metal workbench in free CAD I
21:41
hope you have liked this tutorial if you
21:42
like this tutorial then please like
21:45
subscribe and share my channel one thing
21:49
which uh we have to understood that here
21:52
we are seeing the radius
21:54
difference so we will go to the our
21:57
again this
22:01
flange this Bend 002 and go to the
22:05
properties and give the radius 2
22:12
mm okay now we will go to the our last
22:17
feature yes so this is how we have
22:21
converted the sheet metal orthographic
22:23
drawing into the 3D model
