Hello friends Welcome To freead tutorial
0:03
and in this tutorial we will learn
0:06
assembly in
0:07
freecad we will use A2 plus workbench in
0:11
freeat
0:13
to create assembly here I have a did an
0:18
assembly of a syringe pump with the help
0:22
of A2 plus workbench and I will show you
0:24
from the scratch how you can do the same
0:27
in freeat you can also visit my website
0:30
Mech nexus.com where I write articles
0:33
and tutorials on freeat you can also
0:36
download my tutorial Source Prime from
0:39
the here you can also support my work by
0:43
buying my free cat crash course for
0:45
beginner it is a very basic level course
0:48
for the beginner user where a beginner
0:51
user can Master the free
0:54
Cad and you can also support my work on
0:57
coffee.com you can buy me a cup of of
1:00
coffee you will get my website link and
1:03
my Kofi donation page Link in a video
1:08
description so I will close this file
1:11
and before starting this tutorial first
1:13
we have to install the E2 plus workbench
1:16
to install the a2+ head over to the tool
1:19
and then addon
1:21
manager and here in a drop down select
1:24
the workbenches and type here
1:28
a2+ so you will see here
1:31
a2+ select it and install it and after
1:35
installation of a2+ restart your
1:40
freeat now I will create a new file and
1:45
from here drop down I will switch to the
1:49
a2+ so you can see that uh tools of a2+
1:53
workbench has been
1:56
activated now I will save this assembly
2:05
I will give it a syringe pump
2:09
A2 and I will save it so you can see
2:13
that uh name has been updated
2:17
now here we have the options of uh a2+
2:23
and from here we will add part to the
2:27
assembly so first part we are going to
2:29
add is a body so from my folder I will
2:34
insert the
2:36
body so body has been
2:39
inserted now I will insert
2:45
holder and I
2:47
will place it now we will give
2:52
constraint between this body and
2:54
holder so press the control key select
2:58
the bottom face and the top face of the
3:02
body and once you select on the two
3:05
faces freead will show you the possible
3:09
constraint here now we will select this
3:13
uh add plain coincident
3:18
constraint so you can see that uh
3:21
constraint has been placed
3:24
but I want Direction
3:27
opposite I will accept it now I will
3:32
rotate my model by pressing roller and
3:37
right side button of my mouse at the
3:40
same time now I will select this face
3:43
and this
3:45
face and I will
3:49
place plain coincident
3:51
constraint and I will accept it now it
3:55
has the one degree of a
3:58
freedom if you click on DF degree of
4:02
Freedom so you can see that uh our base
4:05
is
4:06
fixed but this object having the one
4:09
degree of freedom in y direction as per
4:12
our
4:14
UCS
4:15
now I
4:18
will make it a distance constraint from
4:21
this
4:22
face I will select this pH and this pH
4:28
and give the incidence constraint and
4:31
here I will give the distance 23
4:35
mm and I will give it
4:39
minus and I will accept
4:45
it now the next part we are going to
4:48
constrain is a
4:51
wall so I will click on ADD
4:55
part and from my folder I will select
4:58
wall
5:06
now I will select this face and top face
5:09
of my body and place coincidence
5:13
constraint now I rotate my model I will
5:17
select this pH and this pH and again
5:21
Place coincidence
5:23
constraint now it has the 1 degree of
5:26
freedom in y
5:28
direction
5:31
so it is also a 23 mm so I will select
5:35
this
5:36
phas and this
5:39
pH and give the
5:42
constraint and I will give it 23
5:46
mm
5:49
minus and I will accept
5:53
it
5:55
now our third part fourth part will be
5:58
the
6:00
Rod which will be passed through the
6:03
through the hole from this hole to this
6:08
hole so we will assemble four part 1 2 3
6:12
4 which will connect this body and this
6:16
body so I will go to the add part and
6:19
select on rod and insert
6:24
it
6:26
now I will select this face
6:30
and inside
6:35
face and I click on coincidence
6:43
constraint and I will accept it now I
6:47
will select the surface of my
6:50
rod and surface of the
6:56
hole and here free CAD is suggested in
7:00
it is a axis constraint so I will select
7:03
it so you can see that uh Rod has been
7:07
perfectly placed
7:10
from this body to this body similar
7:14
way we will assemble other three Rod so
7:18
go to the
7:20
rod insert
7:22
it and do the same
7:28
process
7:35
click on coincidence constraint accept
7:39
select on the
7:40
surface select on the whole surface and
7:44
give Excel
7:46
constrain now again we insert one more
7:51
Rod
7:57
insert I will select the
8:02
face I will select the inside
8:06
face
8:10
and face has been
8:18
selected let me select the face
8:28
again
8:33
coincidence
8:34
constraint
8:36
accept and select
8:41
surface select surface and give Excel
8:45
constraint now one more Rod is remaining
8:48
we will assemble
8:54
it I will select this
8:58
pH
9:02
and this face give coincidence
9:07
accept select surface and select this
9:11
surface and give XL
9:13
constraint so we have assembled all four
9:20
Rod so you can see that uh it is a very
9:23
similar to the solid works or autod Des
9:26
inventor if you have used those software
9:30
a2+ is very easy to
9:33
use now our uh next part is a
9:38
pusher next part we are going to
9:41
assemble is Pusher so I will click on
9:44
ADD part and I will select The
9:49
Pusher
9:50
now I will
9:53
uh select this whole surface and this
9:56
Rod surface and give the XL con con
10:02
straint apply and I will select this and
10:06
this
10:09
surface and I will select on angle
10:14
plane and from here I will
10:18
give
10:20
0° and I will accept it now I will click
10:25
on my Pusher and click on the transform
10:29
and I will move it now I will give the
10:32
distance constraint between these
10:36
two now I will select this phas and this
10:41
phas and I will give the plane
10:43
coincidence constraint and I will give
10:46
distance
10:50
4.29 I will give it uh
10:53
minus and I will accept
10:58
it
11:00
now we will uh move to the next
11:04
step next step
11:07
is we will insert the
11:11
barrel so I will go to the add part and
11:15
select my
11:21
Barrel I will select the outer face of
11:24
the barrel and this surface and give
11:29
Excel
11:30
constraint now I will flip my
11:34
direction and I will accept it now I
11:38
will select this face and this face and
11:42
make coincidence constraint
11:45
accept next part which we are going to
11:48
assemble is a
11:50
plunger I will select on ADD
11:54
part and select the
11:57
plunger
12:04
now I will uh select my plunger click on
12:07
the transform tool and I will uh rotate
12:10
it as per my
12:13
orientation and I will accept it now I
12:17
will uh make the concentric relation
12:21
with this and uh inside
12:27
face
12:30
accept it now I will give the distance
12:34
constraint first I will switch to the
12:37
isometric and I will give the distance
12:39
constraint between this face and this
12:42
face so I will select this face
12:46
and this face and I will give the mate
12:50
and distance I will give the 15 mm but
12:53
in uh minus
12:56
Direction and I will accept it it now I
13:00
will switch to the isometric
13:02
view so this is how we have made the
13:06
syringe pump assembly in
13:10
freead now uh we will uh see some tool
13:14
of uh E2 plus
13:16
workbench so here uh we have the first
13:19
options to add the part if you click on
13:21
this you can uh browse your folder to
13:24
assemble the part which we have seen in
13:26
this tutorial now from here you can uh
13:30
add a shape from external
13:33
file and uh this is
13:36
the options to edit the constraint if
13:40
you want not to edit any constraint just
13:42
double click on it it will be get
13:45
activated and you can edit your
13:49
constraint at the top you are seeing
13:52
this uh solver constraint if you have
13:55
any conflict with a constraint then
13:58
click on on this the solver this solver
14:00
will solve the your
14:03
constraint it is like a rebuild tool in
14:06
a solid
14:08
works now we will uh see these options
14:12
known as a show only selected elements
14:15
for example if I select the plunger or
14:18
my barrel and if I click on this option
14:21
so it will isolate this
14:24
object if you again click on it so this
14:27
is the basic
14:29
isolate tool of a
14:34
freead
14:36
now if you see any constraint for
14:39
example this coincidence constraints if
14:42
you got any assembly in a free CAD from
14:45
your client but how would you find out
14:48
that this constraint given with which
14:50
faces so select on a constrain
14:54
and click on this magnifying glass so
14:57
you will find that uh this constraint is
15:00
given between this body and this
15:04
body if you select on those constraint
15:07
it will get
15:09
unselected and here is a toggle
15:12
transparency of the assembly if you
15:15
click on this your assembly will be get
15:18
transparent and you will be able to see
15:21
the internal feature of your
15:27
assembly and here is a degree of Freedom
15:30
if you click on it so you can see that
15:32
the red one is a
15:35
fix but this Rod having the one degree
15:39
of Freedom which is a rotational degree
15:42
of Freedom which is not much more
15:44
important so from clicking on the doof
15:47
tool you can find out that uh which part
15:52
is movable in which direction and how
15:54
many degree of Freedom it has so every
15:57
part having the degree of
16:01
Freedom
16:04
now you can also create a part list in a
16:09
freead for
16:11
this if you're using A2 plus workbench
16:15
then click on the part list so it will
16:18
show you save before generating the part
16:21
list save now so click on S yes so you
16:25
can see that a part list has been
16:27
created and if if you double click on it
16:30
your bomb will be created here so here
16:34
uh you can
16:36
modify uh anything you want as for your
16:39
bomb requirement like uh sizes
16:42
material uh any uh special requirement
16:46
like surface finish Etc but here you can
16:48
see that uh here is the item number and
16:51
here is a quantity so body is a one
16:54
quantity holder is one quantity wall is
16:57
one quantity but but this Rod is four
17:00
quantity which we can see in our
17:02
assembly this four rods so a basic bomb
17:05
has been created you can copy this bomb
17:09
into the Excel and uh uh create more
17:13
simplified
17:15
bomb so this is how you can use A2 plus
17:20
assembly workbench in free CAD to create
17:24
an assembly so this is all about this
17:26
tutorial thank you for watching Ing and
17:29
thank you for your valuable time
