hello friends welcome to freekate tutorial and in this tutorial we will model this part and uh you can see that
0:08
uh I have already created this part by reading the orthographic uh views of
0:15
this part and uh if you see the isometric view so you can see that uh our free CAD
0:24
model is matching with a reference isometric view of our drawing
0:30
so this is a very interesting model for the pro user how to create such type of
0:36
a complex part in a free CAD and uh this
0:41
uh part having the lots of features which uh enhance your
0:48
the confidence of uh modeling such type of a part in freead and uh I'm very you
0:56
know very excited to see that free is a capable to model the art like uh like
1:05
other proprietary advanced software can do like uh solid works Autodex Inventor and
1:13
uh you can see that uh how Fread can create such type of a complex model and
1:20
uh it is a very you know uh beneficial for the small scale industry those who
1:27
cannot afford the costly licenses of proprietary softwares ers and
1:34
u they can reduce their uh overall project and operation cost for
1:43
uh to replace the their proprietary softwares and switch on the free I'm not
1:49
saying that the free is very stable there are the lots of bugs which are the
1:56
developers are working as it is a frecad 1.0 zero which is a official
2:03
release and when the upcoming release of a freecad will come then we will see the
2:09
more interesting features inside of the frecad so for this uh tutorial I am
2:16
using the free version 1.0 so you must have at least 1.0 or higher version of a
2:23
free so now uh we will close this file and I will uh show you from the scratch
2:29
how you can step by step read the dimensions because reading a dimensions
2:35
is also an art it's require the lots of a practice to read the dimensions and
2:43
uh if you are very good in a reading dimensions then you can create a 3D
2:49
model like this uh technical manufacturing part in a less span of a
2:55
time so I will not only create this model and I will also explain you how to
3:02
read the dimensions so let's uh start by closing this file so let's close it and
3:09
uh I will uh show you from the
3:15
scratch if you want to learn free CAD from the scratch then you can buy my
3:20
complete free course from zero to expert this course also available on Udemy but
3:27
uh problem is that uh UDMI only give me the 37% of a core selling you can see here
3:35
user had paid $15 but I have only got $5
3:42
so after minus of taxes I get the pennies on each course
3:49
selling if you wanted to see the review of my course you can go to the Udemy and
3:56
s search for the free CAD and you will see my course complete free course from
4:01
zero to expert and this course is took by the more than 2,000 students and I
4:08
have got the rating of a 4.1 for the demo lectures you can expand
4:15
it and uh see the demo lectures and the course structure but I will uh request
4:22
you if you found my course interesting and the reviews of the other student on
4:30
Udemy then I would request you to buy my course from the my coffee shops because
4:39
if you buy from here it will help me a lot so once you buy my course you will be
4:46
redirected to the Google drive and here is the my course complete free course
4:52
from zero to expert go inside and uh the
4:58
sections I have shown you on my Kofi shop page so exactly same lectures under
5:06
the section is created for example section one is a introductions to free
5:13
1.0 and what is new in a freecad 1.0 so if you go to the section one so there
5:20
are the 18 lectures and if you go inside of the sections one you will find the 18
5:28
lecture total and once you go to the lecture one you will find a video file
5:34
which you can download to your system and you can watch it and this course is
5:41
updated on a equal interval of a time once the new feature is came and uh once
5:48
you purchase the course you have the lifetime access to the course and in the
5:54
case of any doubt any query you can mail me at admin at the ratem
6:00
nexus.com at the end you will find one uh video which is a promotional video
6:07
you can watch the video and uh take the whole overview of the course you can
6:12
also explore my shop where you can uh download the tutorial source file and
6:18
some interesting projects on free CAD you can find my course link on my

6:45
purchase will uh help me to grow this channel and it will also motivate me to
6:52
create more awesome content on free CAD so please check out my course on free
7:00
CAD from 02 expert and now we will come
7:06
back to our tutorial so here I have created a new
7:11
file and I will insert my body and on my
7:17
origin plane so now if we see our part orientation so we can see that
7:25
uh this part is symmetric with the mid plane so we will select this uh front
7:33
plane and uh create our base sketch and
7:38
now we will off the origin plane and uh
7:43
we will uh move to our autographic view so now if you see
7:49
here there is a radius of uh 240 so first thing which we will be do we will
7:56
create a circle and uh select a smart dimension and uh we will provide the
8:05
diameter which is of uh twice of the radius
8:10
480 so now we will uh make this as a
8:16
construction because we are going to create our this geometry on this construction circle so first thing I
8:24
will do I will uh select a threepoint arc and uh create one
8:30
arc and now this arc is equal to the our
8:37
construction one and now we will create one more threepoint
8:44
arc and uh if you see here so there is a thickness of 9 mm is given so we will uh
8:53
select a smart dimension and give the a rough dimension
8:59
and now first thing we will do is to provide the coincident relation and now
9:06
this is of 240 and here is a thickness of 9 mm is given so this radius will be
9:13
the 249 so we will uh edit it and
9:18
provide the 249 and now here we will uh create one
9:26
approximate profile so for this we will uh use the polyline
9:33
tool and uh create a rough
9:41
profile and now let's select it and provide the
9:46
horizontal dimension and uh this also make it
9:52
horizontal and now let's make uh this as a vertical so
9:59
now here if you see so basically we are creating this portion and now let's uh
10:07
constrain it so if you see here so from the origin to this top point dimension
10:14
is 173 is given so we will select this and this and uh provide uh dimension of
10:24
173 and here is a thickness of 16 mm so provide
10:31
the 16 mm and now let's uh constrain it to the bottom
10:39
side so let's provide this dimensions 20 mm and now here we will create a fillet
10:48
so let's move now if we see our uh drawing so here is R5 is given so first
10:56
we will select a fillet tool and provide the fillet and uh select a smart
11:02
dimension and provide it R5 and
11:08
now let's uh constrain the other sketches so if you see
11:15
here here is a open loop so we will uh select a line tool and create a line and
11:23
uh make it vertical and now if you see here in our drawing so we can imagine
11:31
that uh this uh axis or we if we draw the line it will match here which means
11:38
that uh we will provide a coincidence constraint with this axis and
11:46
now if you see here so this is the
11:52
unconstrained so let's select a smart dimensions select this point and this
11:57
axis and provide it a 256 why 256 because this dimension is
12:06
given and uh this age is on the axis and now let's see what is the
12:13
unconstrained So here are the points let's uh select it and delete it
12:22
so you can see that our uh sketch is fully constrained and now we will
12:29
extrude it to the distance of 200 mm which we can see here now let's uh close
12:36
it and uh make it uh fit
12:42
all and let's also place this to the isometric view so here if we compare
12:48
with a isometric view so basically we have created this profile and now we
12:54
will extrude it to the distance of 200 mm but we will
13:01
make it symmetric to the plane so select the sketch and uh click on the pad and
13:07
here provide the 200 mm and at the same times make it symmetric to the
13:14
plane and now we will uh create a datim plane to
13:22
create this feature so for this we will
13:29
uh select this face and click on the DATM plane and uh create a DATM plane at
13:35
a distance of 70 from the Z direction so you can see that this is going outside
13:42
of a body so we will simply provide the minus symbol so that it will get
13:49
reverse so now let's check the validity of this plane
13:55
so if you see here so here it is a 140 mm is given and
14:04
it is from the mid plane so we will redefine our plane we will go to the
14:10
attachment editor and we will delete it and go to the model tab and on the
14:16
origin and now here we will define the 70 mm from the mid plane and now here
14:25
let's remove this minus sign so here nothing is wrong you can also take this
14:33
face for the DATM plane but it is not a right practice when you are creating a
14:39
data plane then also always provide the reference from the the main data plane
14:47
of our part because whatever you are going to model the inside this origin
14:53
planes will be remain as it is so if you wanted to provide the datam plane from
14:58
the face then you have to subtract the distance like uh 200 minus uh
15:05
140 and then 30 30 mm you can provide it now let's move to the data plane and
15:16
uh select reference is a exit and 70 mm and say okay so our data
15:26
plane is created and we will off the origin plane and we will right click it
15:31
and recomputee it there is a simple shortcut for this go to the edit and
15:37
there is a refresh option and shortcut is also F5 so you can use the birth
15:44
now let's uh create our sketch and if you see the isometric view so now the
15:51
datam plane which we have created now we will create this profile so select the
15:56
DATM plane and click on the sketch and for the better visibility we will off
16:02
this uh DATM plane now our first job is to project this uh edges so it is very
16:12
simple click on the project geometry project this edge this edge and this
16:17
edge now you are not seeing the projected geometry so better to we will switch to
16:24
the wireframe and if you rotate it you can see that it is created now we will
16:29
create our geometry on this construction one now let's uh select the line tool first
16:39
create a line by joining this point and this point and then we will use the
16:45
threepoint arc select this and this and here we will select this and
16:53
this and uh at a tangent and
16:59
now we will create one arc so we will select a threepoint arc select
17:06
this and this and uh select this and this and add a
17:14
tangent and now if you see our
17:20
uh front view so here is a radius of R15 is given but first we will create this
17:28
vertical line and this horizontal line so we will select the line tool and
17:37
uh create a rough profile and now we will uh select this point and
17:44
this axis and add a coincidence constraint and uh from the origin it is
17:50
a 284 so select uh smart dimension and uh
17:58
constrain this point to the distance of uh
18:04
284 and now we will uh select this point and
18:11
this point and provide it a 30 because this radius is R15 so diameter will be
18:19
30 and now I will uh simply select this point and this point and go here and
18:26
provide the horizontal constraint now we can create an arc which will be tangent
18:32
to this edge and this edge so select the arc
18:39
tool and uh make it tangent
18:45
so now if you see here our uh sketch is fully constrained and we will come out
18:52
of it and uh let's switch to the flat line for
18:59
preservability so here if you see this uh profile is not closed so we
19:06
will again go to the sketch this happens because this axis is there so I missed
19:14
that it is open so it is very simple just uh create a line and uh select this
19:22
point and this point so now come out of it so we have a
19:29
fully closed profile and now select the sketch click on the
19:35
pad and here if you see we have created our
19:41
plane here so material direction will be on other side so we will click and we
19:48
will say reverse and provide the thickness of 16
19:54
mm so to cross check it we can on the origin plane and switch to the top view
20:01
so we can see that uh this part is within the limit of this data
20:07
plane now switch to the isometric
20:13
view now we will provide the fillet so if you see here the diameter is of 50 is
20:22
given so we will provide a radius of 50 mm so select the age and click on the
20:28
fillet and uh this is of a diameter 50 so provide the radius
20:34
25 and say okay and now as in a isometric view we
20:42
can see that this feature is the same on the other side so we will uh simply
20:47
mirror it so first we will press the control key press the pad and then fill
20:54
it and uh click on the mirror
20:59
and now you can see that frecat took this y z reference which is wrong we
21:06
have to define along the xz so we will go here and uh click on the select
21:11
reference and select it and say okay so you can see that this feature is
21:18
mirror on the other side with fillet and now let's uh create one more data plane
21:28
this DATM plane will be on this face so we will uh select it and uh DATM plane
21:35
we will define the distance 9 mm say
21:41
okay and we will create our next sketch on this data plane so
21:48
here we will rebuild our data plane and select the data plane and click on the
21:56
sketch and now here we will hide it and we will simply
22:03
project this radius which we have created in last step so when we project
22:09
it we get a center so we will uh click on the circle and create a circle and
22:16
here I will simply select this and this and add a coincidence and let's come out of the sketch and
22:25
uh we will uh create the pad which will
22:31
be go from here and come outside of the our second pad feature so how to do this
22:39
select the model select the sketch and click on the pad and here
22:47
we will click on the reverse so you can see that
22:52
uh it got reversed but here our aim is to go to the face and we will select
22:59
this face and at the same time we will define
23:05
the face to offset so we can see that uh this is a 200 and this is a 140 and here
23:13
is a 21 which means that uh this is to this is of uh 30 and this is the 21
23:21
which means that this is the 9 mm so here is a offset we will provide the 9
23:27
mm so you can see that how you can uh use
23:34
the up tophase with a phase 2 offset and now click
23:40
okay and now on the same data plane here we will
23:46
uh create the sketch which is the this one so we will select the data plane and
23:54
uh click on the sketch now we will uh select the plane and
24:01
click on the sketch and here is the profile which we want to create so
24:08
let's hide the datam plane and here we will click on the project geometry and
24:14
uh project this uh outer radius and project this horizontal edge and now I will
24:22
select a rectangle and I will create a rough rectangle and I will uh delete it
24:29
now I will select this point and this arc and add a
24:35
coincidence select this point and this arc and add a coincidence and
24:42
now here is a 30 mm dimension so I will give it a
24:49
30 and now you can see that uh it is got a
24:57
constraint so let's press Ctrl Z and it is got constrainted to the
25:05
midpoint so we will go here and uh
25:13
let's delete it
25:19
delete
25:26
it delete it
26:00
now we will uh click on project geometry and project this radius and this horizontal edge
26:07
and uh we will uh switch to the wireframe and uh we will create a
26:15
rectangle and we will delete this line and here we will use the trim tool so
26:22
trim the extra geometry and now let's constrain the position select a smart dimension and uh
26:31
provide this 30 mm and we will also project this horizontal
26:37
age select a smart dimension and uh provide the
26:46
140 and uh move it and now select the threepoint
26:53
arc select this and this and
26:58
here we will select this and this and made it equal
27:03
so our sketch is fully constrained we will come out of
27:09
it and now let's uh switch to the flat
27:17
lines and now we will uh extrude it select the sketch click on the
27:23
pad and uh
27:29
here we will uh provide the length of 24
27:35
mm first select up to face and select this
27:41
face and here offset 24 so you can see that uh it is created
27:50
as we can see on our drawing and we will say okay and now if you see the isometric
27:58
view this feature is same on the other sides so we will select the pad click on
28:04
the mirror and uh select it and select this uh exit
28:12
plane and click on the mid plane to mirror it
28:18
and now we will uh create this hole so for this we will select the face and
28:25
click on the sketch we will uh click on the project
28:31
geometry select the circle and here provide
28:37
the diameter 30 click on close
28:43
select the sketch and we will uh create it with the whole feature so click on
28:50
the whole wizard and if we see our drawing so here is a drill of 30 mm so
28:57
here diameter I will provide 30 and I will uh put in conditions through wall
29:04
and say okay now press zero for isometric
29:10
view and now we will uh create this cut so for
29:16
this we will uh select the face and uh click on the sketch and
29:22
now we will uh create a rectangle and uh then we will uh create
29:32
a line and now I will use the trim options to trim it
29:41
and now I will uh delete this line and I will create a threepoint
29:48
arc which will coincident with this center so let's create a rough
29:54
threepoint arc and first let's uh merge the
30:00
center say coincidence and here we will also delete this line and now I will make this and
30:09
this coincidence this and this
30:16
coincidence and now let's uh constrain the dimensions select a smart
30:22
dimension say 60 and uh move
30:29
it and we will project this age click on the project geometry and select a smart
30:44
dimension and uh provide the dimension 15
30:49
mm and provide the horizontal dimension of a
30:54
20 and now let's uh constrain this radius so
31:00
this is of 264 and let's move the dimensions so
31:05
that uh you can clearly see it and now here 264 is a addition of 15 mm to this
31:14
radius say close and now we will create a cut which will be the through wall
31:21
select the sketch click on the cut and from here say it through all say
31:30
okay now we will uh provide the R5 fillet so click on the
31:38
fillet give the value 5 mm and
31:45
uh select it select
31:53
it select it and select it
32:02
select this
32:08
edge select
32:14
it select it and select it so all the edges is
32:21
selected which are added here if you wanted to remove any edges you can
32:26
simply click on remove option and we will say
32:33
okay so you can see that fillet is created now move to the next feature
32:39
next feature is to create this cut so we will place our model to the isometric
32:44
view and we will uh select this face and click on the
32:50
sketch and uh let's create a
32:57
rectangle and now let's provide the dimension select a smart
33:02
dimension and uh give it uh 85 and uh let's also project this
33:11
age select a smart dimension select uh this and this and uh provide it of
33:20
55 and uh the cut depth is of 5
33:27
mm which you can see here now click on close and now we will uh make it a
33:35
through all cut so select
33:40
it and from here say it through all say
33:47
okay and now we will uh provide the fillet as a depth is of a 5 mm so if we
33:56
provide the exact fillet of 5 mm frecad will not take so we will select the
34:03
fillet and select it select this
34:09
edge so here you can see that by mistake face is got selected so we will simply
34:15
remove it and select the
34:22
age now select the other two edges this one and
34:29
uh this one so now here if I cue the 5
34:34
mm fillet it will fail because this is an bug of a free cat so
34:42
we will uh provide the fillet 4.99 and say
34:50
okay so you can see that a fillet is created so why it was not taking 5 mm
34:56
because these two edges will be get merged therefore we have given
35:01
4.999 which is a very very very close to the 5 mm so now let's uh move to the
35:09
next step in the next step if you see our isometric view so there are the
35:15
fillet so we will provide the fillet to the four corners here here here and here
35:24
so let's select a fillet and here we will set the value 5 mm and let's select
35:33
the
35:39
ages here face is got selected remove it so when you are facing a problem in
35:45
selection then zoom it and then select it same way on the other
35:51
side zoom and then select let's select on the other
36:02
side and also keep in point that the edges you are selecting it must be get
36:08
added here now select this
36:14
edge and uh select this
36:27
edge select this edge
36:36
select this age and uh just cross check
36:42
by rotating the model that uh all ages are selected now say
36:51
okay so you can see that uh fillet is created with respect to our
36:57
model and now if uh some fillet which you cannot
37:03
see here you can add it now uh we will uh create this
37:09
hole so select the face and uh click on the sketch and it is very simple to
37:16
create whose detail is given here so first thing which we will do is to
37:23
project this vertical edge and uh select the circle and
37:31
uh give it a 15 mm and from the position to this
37:45
point and uh provide the 15 mm And uh
37:50
from this age to the center position is of a 15
37:59
mm let's make it a 15 because here is a 30 given so this is under
38:05
the center of this 30 and now we will close
38:10
it and now select the sketch click on the cut
38:17
or you can also use the whole vizard
38:23
tool let's say through all say
38:29
okay and now let's move to our isometric
38:34
view we can see the cut here whose detail we can see here so for this we
38:41
will press our model to the isometric view and here we will on our origin plane and
38:49
uh we will select this top plane and click on the sketch and
38:56
here we will switch to the wireframe view and hide the origin plane now
39:03
here I will uh select a rectangle and uh here we will provide
39:11
the dimensions which we can uh see here so first we will uh make it uh
39:20
symmetric so click on the symmetricity and uh select this point
39:27
this point and this axis and now select the smart dimension and I give the
39:34
dimension so here if you see so this is the 80 mm so provide the 80 mm
39:41
dimension and uh this is of a 35
39:46
so provide it 35 and here there is a fillet of R5 so we will
39:54
create inside the sketch click on the fillet select this
40:01
and this edge similarly this and this edge and here I will select a smart
40:11
dimension say 5
40:19
mm and uh click it equal now let's come out of the
40:28
sketch and uh let's switch to the flat lines
40:36
and uh select the sketch and uh click on the
40:47
cut and from here say it through all so we are not seeing the cut here so
40:54
we will reverse the direction so you can see that a cut is
41:01
created now say
41:08
okay now let's move to the next feature so if you see the top view and side view
41:16
so we can see here the hidden lines which means that uh there is a cut
41:22
so we will switch our model to the isometric view and we will rotate our model and uh create a
41:31
sketch and here I will rotate my model to the right orientation which is the
41:36
left one and now here I will project this horizontal edges so click on the
41:45
project project this and this and uh select
41:51
uh rectangle and now we will uh make it symmetric select this and this and this
42:01
axis and uh select a smart dimension and uh give it uh
42:09
92 and uh provide the position from this
42:17
edge and uh click on
42:23
close and select the sketch click on the cut and uh provide the cut depth of 4
42:37
mm let's give here 4 mm value say
42:45
okay and now let's uh provide the
42:52
fillet so if you see here there is a
42:57
fillet so we will click on the fillet
43:03
tool select this
43:08
and this and here we will provide the fillet
43:13
of uh 4 mm let's
43:21
see so fillet is created and
43:27
now move our model to the isometric view so now if you see our isometric view so
43:34
there is a cut so we will select the face and uh
43:40
click on the sketch and here I will
43:47
uh click on the project geometry
43:52
and uh select a rectangle
43:58
tool and here we will project this edge because if we go to the our uh view this
44:09
and this line are the collinear
44:16
select this and this and uh press the
44:21
horizontal constraint and now we will select the sketch click on the
44:36
pocket and let's wait because this model is heavy so some of the operation might
44:42
take time so have the patience and say okay and now there is a fillet of R15
44:54
now we will uh press control key and select these two age and directly click
44:59
on the
45:04
fillet and provide the R15
45:12
fillet and say
45:17
okay and now let's uh see the next
45:23
operation so if we see our uh isometric
45:29
view so it is approximately matching and we will also provide the
45:37
color to make it a perfect and uh there are some minor
45:43
things which you can do like uh providing the fillet of R5 to these
45:50
edges so let's also do it and then we will apply the color
45:56
so here I have selected the fillet tool and uh I
46:01
will select here and select this edges select this
46:10
one this one and uh this one and this one and
46:20
provide here 5
46:31
mm say okay so this completes our model
46:37
so let's uh see our model in a isometric view now you can see that uh our model
46:45
is uh completely matching with our uh reference drawing and uh this is not
46:52
only the end we will provide the color as well and there are the some fillets which I
46:59
am not going to give it because tutorial will be too lengthy so you can provide
47:05
the fillet like I have provided here and now let's give the color to give the
47:13
color select the body and go to the appearances in appearances section
47:19
scroll down and here you will see the option of current appearances click on it and uh here we will select the red
47:27
color and we will drag our color to
47:33
match with our reference one so I think that this is the good color and we will
47:40
say okay so you can see that
47:46
uh color is applied but at the same times we can see that this and this phases having the different color so
47:53
there is also method to do this so for this there is a feature in a part
48:00
workbench which is a known as a face feature so if we click on the any face
48:06
so this tool get highlighted so let's select this phase and uh activate it and now here we will
48:16
select the phase so once you select the face this is the face number 100 which is got added here and now press the
48:24
control key and select the faces which you want to add so as you can see that I
48:30
am uh adding the faces and this is going to be added here 185 32 43 73 and uh
48:40
let's select this surface and this surface and
48:47
now go to the custom appearances and instead of a red we will give here white
48:53
color click on the close so now our free CAD model is a
49:00
exact replica of our reference one so this is all about this tutorial how you
49:08
can model this complex part and uh this part is a very good example for the pro
49:15
user of a free those who wanted to create a complex model with the help of
49:20
a free part design workbench and the beauty of a free is that uh you can use
49:26
the multiple workbenches to create a part for example we have created a part
49:33
in a part design workbench but for giving the colors we have used the part
49:39
workbench so that is the benefit that you can use the multiple tools of
49:44
multiple workbenches to make your awesome parts so this is all about this
49:50
tutorial thank you for watching and thank you for your valuable time
