Hello friends welcome to Free care tutorial and in this tutorial we will do modeling and assembly of a C
0:08
clamp and as you can see that I have uh model all the parts like a clamp screw
0:15
bar Bush and cap and I have assembled it and my assembly view is matching with my
0:21
isometric view so to create this assembly I have
0:27
used the default assembly workbench which which is very convenient with respect to the a2+ and assembly
0:36
4 I will model each and every part in this tutorial and I will show you from
0:41
the scratch how you can do the modeling as well as assembly for this I am using the freead
0:49
uh version 1.0 and it is a release candidate 4 I hope you have installed
0:54
the latest version of a freead on your system if you are a Windows user then I
1:00
have already made a video on my YouTube channel how you can run freead 1.0 on
1:07
windows so I will uh close this file and create a new file and I will show you from the
1:15
scratch you can also visit my website Mech nexus.com where I write articles
1:21
and tutorials on freead you can download my tutorial source file from here
1:27
tutorial source file page and you can also support me by buying a cup of
1:35
coffee on kofi.com your small support will help these channels to grow and it
1:42
will motivate me to create more awesome content on freead I thanks to all my
1:48
supporter those who have supported me by buying a cup of
1:53
coffee so keep supporting and uh it will help me to grow this channel Channel and
2:01
it will motivate me to create more awesome and useful tutorials on freeat
2:07
so let's come back to our tutorial so here I have created a new
2:12
file and uh I will switch to the part design workbench and here I will create a body
2:20
and then create a sketch the first part which we will model is a clamp so clamp Dimension is
2:29
given here now we will start our
2:35
sketch so with respect to the orientation of our clamp so we will
2:42
select the right plane and uh create our sketch so we will select the right plane
2:48
and say okay and now here we will read the drawing so what we
2:55
will do we will first create this profile and we will create this outer
3:02
profile as a construction so let's uh start our
3:08
sketching so I will create a
3:16
rectangle and I will uh delete this
3:21
line and I will select all this line and make it
3:27
construction and provide the fillet of R30 at this locations and this locations
3:33
so now click on the fillet provide the fet here and here and
3:41
I will select this line and this point and uh make it
3:46
coincidence and now I will uh make it this and this point
3:52
symmetric so first give the radius of uh
3:57
30 and this one also
4:04
30 and I will use the symmetricity select this point this point and this
4:11
axis and select a horizontal Dimension and uh provide the dimension
4:20
120 and uh provide the height which is of 98
4:27
mm similarly here
4:34
so now this is the outer profile which we have made and now here is a two
4:42
radius one is the R30 which we have a made and one is a r10
4:50
so what we will do we will select the polyline tool
5:01
and uh create a rough
5:18
profile now let's uh give the
5:25
constraint so first thing which I will do is to make it a horizontal
5:30
select this and this and add a horizontal relation select this and this
5:37
and add a horizontal relation and
5:43
now I will uh create a fillet at all the sides so click on the
5:49
fillet select this this this and
5:55
this this and this
6:01
now I will uh merge the center of this radius merge it similarly this and this
6:10
merge it
6:31
5 mm and this outer one is of 10
6:37
mm now I will move the dimensions so you can see
6:44
it so R5 and r10 and now uh for the
6:50
representation purpose we will uh select a line and uh close this
6:58
profile and and uh do not forget to make it construction select these two and make
7:05
it construction so here our profile is uh fully constrained if you see here so
7:13
this is the 8 mm and this outer one is of 20 mm so if
7:21
you see in model here so that will be maximum of the 20 mm which is a maximum
7:28
dimension so select the sketch click on the
7:34
pad provide the 20 mm and uh never forget to make it symmetric to the plane
7:41
click on okay and
7:47
now let's uh move to the isometric view so we can see here the fillet if we go
7:53
in a drawing so here is a r10 fillet is there so we will select this age and
8:01
this age and click on the fillet and provide the fillet of
8:08
99.999 now we will create this pad here so for this we will select the phase and
8:14
uh click on the
8:19
sketch click on the project geometry project one of the
8:25
radius and uh select a line
8:32
tool project the edges and then create a line so select the line
8:41
tool draw one line here one line here and uh create a three-point
8:48
Arc select this point this point and this one and uh
8:56
select a line tool and uh
9:01
provide the horizontal Dimension and now I will fix this uh length select a
9:10
smart Dimension select this point and this point and uh provide it
9:15
23 click on close and now create a pad of 20 mm click on close it select the
9:24
pad and uh provide the 20 mm click on
9:30
okay and now we will create this mid feature if you see in a Right View which
9:38
is of 8 mm thickness so we will on our origin plane and we have the plane as a
9:46
center which is a YZ plane so we will select this YZ
9:51
plane and click on the sketch and hide our origin plane and now
10:00
first I will use the project geometry project this age this age this age this
10:06
age this one and this one so better to place our model at a
10:13
wireframe so that we can see our projected line
10:19
now we will create a exact line and
10:24
Arc with respect to the our projection so select the line tool
10:30
select this and this and select a 3point
10:41
Arc select line tool select this and select a three-point
10:51
Arc so rotate our model if you are facing difficulty you
10:58
can also create get a sketch in a isometric view but I prefer in
11:04
a normal to the my screen so that I can pick the point easily now we will rotate
11:12
it and let's see what is unconstraint so this is the unconstraint because it is not equal
11:21
apply the equal constraint similarly here let uh find out here is
11:28
also same
11:39
issue so we have uh created a profile with respect to our projected geometry
11:46
and now again we will select a line tool
12:00
and uh make it horizontal and uh we will create a
12:05
fillet on both the sides so click on the fet select this and this
12:13
this and this and
12:18
now select this and this and add a coincidence so here
12:34
here it is a some issue now let's select this and this and
12:42
add a conidence yes so let's uh move to the
12:50
nearby and select this and this and add a coincidence yes so you can see that
12:56
our profile is fully constrained and we will switch to the flight lines and uh
13:02
this rip or we can say that this features which is seems to be like a plate having
13:10
the thickness of 8 mm so select the
13:20
sketch and uh we will move to the pad options to create a pad
13:31
so select the sketch click on the pad give the 8 mm and uh make it symmetric to the plane
13:39
click on okay and
13:45
here we have created uh overall shape of the clamp and now move to the next
13:53
feature our uh next feature is to create a hole
14:00
which is of M12 so we will select the face and uh
14:05
click on the sketch and we will rotate our model click on Project
14:13
geometry and uh create a circle of 12
14:22
mm 12 mm and uh move to the whole Wizard
14:27
and from here select uh isometric regular profile and in a drop- down
14:33
select M12 and from here select the dimensions
14:42
25 no issue this is the just open to the other side and click on
14:50
okay now our next feature is to create a cut which we can also see in here in our
14:58
uh 2D drawing so select the phase and uh click on the
15:03
sketch click on Project geometry project this and
15:09
this select line
15:17
tool select a smart Dimension select this and this and provide it to 30 mm
15:33
now click on close and uh click on
15:39
Cut and say here through all say
15:52
okay so here we have a created a model of a clamp
15:59
and let's apply the color so select the last feature and uh click on
16:07
appearances and here click on the custom references and click on diffuse color
16:13
and let's select the color click on
16:22
close so here we have created a model of a clamp now we will uh create a model of
16:29
this screw now we will create this screw and
16:36
if you see in assembly so this is our
16:44
screw so here I have inserted my body and activated the part design workbench
16:50
and now I will uh switch to the right plane and uh create our sketch
17:01
go to the model Tab and hide it and now I will uh select the polyline
17:06
from
17:24
here select it and add a vertical and now we will give the
17:31
dimension select the dimension
17:39
tool this is 3
17:44
mm and this is the 6
17:52
mm and total length is of 130 which we can see here
18:00
here so provide the 130 and this is offer
18:09
22 and this uh diameter of a 20 so provide the radius
18:15
of 10 mm
18:20
and this is of 12 mm so this is a very simple part this
18:28
our screw which we will made with a single Revolution so come out of the
18:37
sketch select the Revol tool and uh select reference and Revol
18:44
around the Y AIS click on okay so our base feature is created and
18:53
now we will uh create the whole
18:58
because this bar will insert here so we will set our model to the
19:04
isometric and we will on our plane and uh select this plane and click
19:11
on the sketch and from here I will switch to the
19:17
wireframe and let's uh hide the the template and now here I will
19:23
create the circle of a 5.5
19:30
and I will project this
19:36
age select the smart Dimension select this and this and uh provide the 12
19:46
mm and we will come out of the sketch and from here we will switch to
19:53
the flat lines select the sketch and we will click on the cut and
19:59
we will uh make it uh through all and keep it symmetric to the plane so our
20:07
hole will become through now let's uh move to the next
20:17
feature which is to provide some approximate color and here if we see our
20:25
screw so here it is a M12 tra and if we go in our model so we have
20:32
provided this uh diameter 12
20:37
so I have a macro called a cosmetic thread I will go to the micro and uh
20:47
let's execute it and select
20:55
it cosmetic trade so you can see that a cosmetic threade is
21:03
inserted even though this is not uh very
21:09
perfect so I hope in upcoming release some
21:15
cosmetic thread options will come like solid was as of now I will delete it and
21:21
uh let's view color so here
21:29
uh let's apply it Chrome because it is shiny and uh from
21:36
Custom
21:42
appearance click on Okay click on
21:49
close now we will Moder our next part which is a
21:55
bar so I will save it as a screw
22:06
here I have a save my part as a screw click on Save and uh let's model this
22:13
bar so I will close it and I will go to the new file and insert my
22:20
body and uh On the Origin
22:26
plane and here it is a very simple part so I will select a right plane and click
22:31
on the sketch go to the model Tab and hide it and
22:41
uh it is off a 96 of diameter 5 so give it
22:49
2.5 and this is of 96
22:58
now close it I will revolve it and revolve around
23:05
to the Y AIS click on
23:11
okay so if you see our model so this is a bar so we will
23:18
provide some minor entry Cham
23:24
for Let's uh give it 0.5 click on
23:30
okay now I will save
23:40
it let's I give the
23:46
name now I will close it and let's move to the next
23:52
part which is to create this bush so so here I will create a new file
24:00
again and insert my body On the Origin
24:06
plane so here I will select the right plane again and click on the sketch go
24:13
to the model Tab and uh hide the origin plane so here I will select a polyline
24:23
tool and uh create a rough profile
24:53
so this is our basic profile and now we will uh constrain it with the
25:00
dimension but here I will uh create as it is with respect to our
25:08
uh 2D view because here is a flat face of 2 mm so now let's uh give the
25:16
dimensions select the dimension tool and uh this is of 2
25:24
mm and this two this uh Center
25:29
so radius will be the 7 mm because it is a 14 and now I will uh move it and provide
25:38
this one as a horizontal overall it is 20 so from here to here it will be
25:49
10 and let's move it and it is a 11 mm so it will be
25:56
5.5 select this and this and provide
26:04
5.5 so here is it is a 2 mm and outer one is of
26:11
a 3 mm so I will make it 3 mm and let's move the
26:18
dimension and uh again select the dimension tool select this and this and
26:24
uh it is of a diameter 7.6 so it will will be 7.6 /
26:33
2 and uh let's define the overall length which is of 16 mm which we can
26:40
see here so let's uh cross check all the
26:45
dimensions so we have provided the 14 our radius is of a
26:50
7 7.6 16 everything is correct and our sket is also fully constrained so we
26:57
will come up out of the sketch now select the Revol and from
27:03
here we will select the Y AIS and click on okay so here we have
27:12
uh made this
27:17
bush and let's apply the color switch to the
27:25
isometric and go to references and uh from here I will select the
27:32
Chrome because it is shiny and uh from here uh let's uh select some different
27:41
color for this part let's see how it is look okay now I will uh close it and I
27:51
will save it as a bush so click on Save
28:03
here I will the push underscore
28:09
app and now the next feature we will create is a cap which is a very simple
28:21
part so here if you see this is the four number is of a
28:31
cap now let's uh close the current file and create a new file and we will insert
28:38
the body and On the Origin plane and we will
28:45
select this right plane and click on the sketch go to the model Tab and hide the
28:51
origin plane and now here I will again select the poly line
28:58
and uh create a rough
29:09
profile so we have created a rough profile now let's uh give the dimension
29:14
select the smart Dimension and inner one of the
29:20
six or our length is of 9 and uh this is of a diameter five so
29:27
from here to to here it is of uh uh
29:34
2.5 and uh outer one is of uh 4
29:45
mm and let's uh move it to the
29:51
inside now here we can see inner diameters of the file 5 mm and
29:59
this is the six and we have to Define this one here
30:05
so here if you see it is a close so we will select uh this Arc and our origin
30:11
point and uh make it a
30:17
coincidence let's move the dimension now select this line and this
30:23
and add a coincidence relation now we will close it and uh we
30:30
will revolve it and from here select y
30:35
AIS click on okay so here is a 8 mm it is a 7 mm means
30:42
uh. 5.5 chamfer so provide the
30:53
chamfer click on okay and here is our cap is completed
30:58
Let's uh give some random color and uh click on
31:22
save so we have created all four models
31:27
and now now we will uh start our
31:33
assembly now we will uh create the assembly as we have created the model of
31:39
clamp screw bar cap and Bush and here I have created new file
31:46
and uh I will first save this file
31:58
so here I have a save my files and uh I will use the
32:05
default workbench so I will switch to the
32:10
assembly and here you will see that uh tools are the different with respect to
32:17
the assembly 4 and a2+ so here first option is that create a
32:24
assembly so here I have a inserted the assembly now here is the options to
32:31
import component and click on open file and uh first component which will
32:40
we insert is a
32:45
clamp now select this body and here it
32:51
is asking whether you want to the first grounded part your first part will be
32:57
the get grounded so I want yes click on okay so as my first part is
33:06
a grounded so you can see here the lock symbol and uh if you go here under the
33:12
joints you will find that grounded point and you can hide it if you do not like
33:18
it and now the second component which will be
33:23
insert is the screw so click on insert component click on open
33:30
file and we will insert our
33:36
screw here screw is inserted select the body click on okay and
33:44
now here it is inserted at a body so I will uh select it and press f2 rename it
33:53
and I will give it a clamp and press f2 and uh give it
34:02
screw and I will refresh it now I will
34:08
use the transform tool click on okay now I will insert my
34:16
screw in this clamp so
34:22
here you can see the icons icons are inactive because I have not activated my
34:29
assembly so click on the active object now it is activated now here we have the multiple
34:37
options so we will use this create a cylindrical joints so I will select
34:46
this and this by pressing the control key and
34:52
click on this constraint so you can see that it is inserted and here is also
34:58
option of a flip but I want as it is click on okay
35:07
now I will uh short my browser here and
35:14
uh update it now I will uh click on the
35:19
transform and I will rotate my model little bit click on okay now
35:28
I will On the Origin plane of
35:33
my screw and here I will place it as the
35:39
isometric and now I will On the Origin plane of the assembly now I will select
35:45
this and this and I will apply the parallel constraint so here my body is not active
35:53
so first I will activate it and now I will select This Plane
35:59
and this plane and here is a parallel
36:06
joint and click on okay so best thing about this uh new assembly workbench is
36:14
that we can give constraint with respect to the plane to plane and now here I
36:20
will off the origin plane and here distance is not that much
36:27
important but to fix my part
36:33
to fully constrain my part I do not want any degree of Freedom should be left so
36:40
I will select the this pH and uh this phase of my
36:47
screw and here is a distance constraint and here I will give some
36:53
approximate distance let's say 20 mm or uh you
37:00
40 and I will set it to the isometric
37:07
now I will uh insert this uh F number part so I will uh go in insert
37:15
click on the [Applause]
37:23
open and here is my bush
37:31
now I will rename
37:38
it now I will uh move my wsh to the
37:44
outside of the body and now here I will press the control
37:51
key and first I will uh select this inner cylindrical f this and this
37:59
one and here uh first I will activate it select
38:06
this and this and apply the same constraint cylindrical joints and click
38:14
on okay now we will uh use the transform tool to
38:22
move little bit outside now select this face
38:29
and this face and we will apply the
38:37
constraint select this and this and
38:44
here we will use the distance joint and we will keep the distance
38:51
zero now let's switch to the isometric view now we will uh insert this bar
38:59
which is item number three so I will go in uh insert component click on open
39:07
file and we will go to the bar and insert
39:12
it so here is my bar which is inserted here click on okay now I will give it a
39:21
ring Name by pressing the F2 and give it bar and let's collapse
39:34
it now I will uh use the transform tool
39:39
to set my bar in the position actually it doesn't matter but
39:45
uh it is my practice activate the
39:50
assembly and press the control key select this and this and use the
39:58
cylindrical constraint click on okay now switch to the this View and uh
40:07
let's uh give some distance constraint approximate distance so use
40:16
the distance and let's give it uh 35
40:21
mm or 45 yes it is looking symmetric from the
40:28
both the S side now switch to the
40:34
isometric and now we will insert the two
40:40
caps now C go to the insert click on open
40:45
file and here is a cap
40:54
and where it is inserted so cap cap is here click on body insert it is and uh
41:03
rename it to the cap move it
41:08
outside and also rotate it now select this and
41:18
this and uh we will use this constraint but we will uh activate our
41:25
assembly and Let's uh select this inner surface this inner
41:39
surface and uh we will say okay and now we will move
41:47
it let's see it is a reverse or uh yes so we will reverse it so now we
41:56
will go to the assembly and go to the joints and this is the cylindrical joint and here we will flip
42:03
it click on
42:09
okay now we will uh move our cap to the
42:19
outside select this
42:28
and here we will provide the distance
42:37
constraint so you can see that uh it got assembled
42:43
now again click on insert and click on the cap so one more
42:51
cap is inserted give it a name again cap
43:00
now I will move it to the outside of a
43:06
body and now here we will uh
43:19
transform first activate the
43:25
assembly and and click on this cap
43:31
and rotate it and now here what we will do first we will select the this inner
43:44
face select this interface and this
43:53
face and uh here we will use the distance M and give it
44:00
zero click on okay and uh
44:08
here we will use this distance M and we will flip
44:15
it and you can see that uh it got perfectly made here we have a reduce one
44:23
constraint which is of a cylindrical constraint so now if we switch to the isometric
