Hello friends welcome to Free care tutorial and in this tutorial we will uh model this part as you can see that uh I
0:08
have already modeled it with respect to this uh orthographic View and you can
0:14
see that uh our freead model is matching with the isometric view of the
0:20
drawing I will show you from the scratch step by step how you can model this part
0:27
in freead with the help of uh part design workbench for this tutorial I'm using
0:35
the freead version 1.0 you must have at least 1.0 or higher version of a
0:43
freead so I will close this file and create a new
0:51
file you can also visit my website Mech nexus.com where I write articles and
0:58
tutorials on freead and you can also access my 3D
1:04
part library off a freead you can download the part from here and you can
1:11
use in your projects with modifications you can also access my 2D
1:18
drawing Library where you can uh download this 2D drawings and uh you can
1:26
create 3D models with respect to this draw drawings you can also support me on
1:35
kofi.com you can buy me a cup of coffee your small support will help these
1:41
channels to grow and it will motivate me to create more awesome content on uh
1:48
free cat you can find my Kofi donation page Link in a video description as well
1:55
as you can also see my Kofi page URL on this hiter
2:01
so let's come back to our
2:07
tutorial so here I have created a new file and I have activated the part
2:13
design workbench and I will create a body and On the Origin plane so as per
2:20
orientation of our part we will uh select this top plane as our first plane to create a
2:28
sketch select it and say
2:33
sketch and now we will switch to model tab select the origin and press the
2:39
space bar to hide it and now I will select a
2:46
rectangle and now I will uh make this point and this
2:52
point symmetric so I will select this uh
2:57
constraint symmetric then select this point this point and this
3:04
axis and now select a smart Dimension and uh this is the
3:12
140 and uh vertical is of uh
3:21
170 now close the
3:27
sketch now select the sketch click on the pad and give the pad distance 14 mm
3:34
which we can see here say
3:40
okay now switch to the isometric
3:45
view now we will uh select a mid plane and uh create the pad select the origin
3:55
plane and select this mid plane and say sketch
4:00
go to the model Tab and hide the origin and now from here we will switch
4:07
to the wire frame and we will click on the project geometry and project this
4:13
age and now I will uh
4:19
create a rectangle and now select smart dimension
4:30
this is the
4:36
51 and total height is of a
4:44
140 this Dimension is of
4:49
74 so our uh sketch is fully constrained and now we will uh create
4:56
extrude of 120 mm and keep it simp metric to the plane so come out of the
5:03
sketch and from here switch to the flat lines select it and click on the
5:11
pad give it 120 and make it symmetric to the plane
5:17
say okay and
5:23
now we will create this uh soft solid profile at the
5:30
back side so we will select this pH and uh click on the
5:36
sketch press zero for isometric View and now here I will create a
5:46
circle and let's switch to the rear view and now let's uh constrain
5:54
it so from the origin at the bottom it is a 95 so select smart Dimension select
6:02
this and this and give it a
6:08
95 and here give the 60 and say close and
6:17
now let's add the material to the circle so select the sketch click on
6:23
extrude and uh give this Dimension 61
6:31
now we will uh create this cut so for this we will select this backside View
6:38
and click on the sketch we will click on the project geometry and project this uh horizontal
6:46
and vertical and now we will uh draw the horizontal and
6:53
vertical line and here
7:01
we will click on the project geometry and from here we will uh switch
7:07
to the wireframe
7:12
now we will delete this constraint and uh move this
7:18
point or we will delete it and create one Fresh
7:24
Point now select this point and this origin point and and say it
7:30
horizontal select this point and this point and add it the vertical
7:38
constraint so these two lines are the fixed now uh we will create one
7:46
Arc which will be tangent to this say tangent so here our profile is
7:54
closed now we will switch to the flat lines
7:59
one switch to the Shaded and then switch to the flat lines so
8:05
now we will uh remove the material to the distance of a 42 select the sketch
8:10
click on the cut and from here give it 42 say
8:16
okay now we will mirror this pocket on the other side so click on the pocket
8:24
and click on the mirror and from here select reference
8:30
and uh select this mid plane and say okay so now you can see that uh this
8:38
feature is created in our fread model now let's uh move to the next step
8:47
so in a backside view if you see in these sections there is a rib so we will
8:53
create that D so for this if you see our model orientation we
8:59
will uh select this backside face and click on the sketch and from here we will uh switch
9:07
to the wireframe view and now we will project this bottom IM click
9:14
on the project geometry and at the same time also project
9:20
this diameter so when you tilt it you can see it and now let's uh select a
9:28
rectangle and now let's uh delete this and uh we
9:36
will uh make this thickness of the rib symmetric so for this we will uh use the
9:42
symmetricity constraint select this point this point and this axis so you
9:48
can see that two symmetric arrow is created now select smart Dimension and
9:54
uh give it a 10 mm thickness and now use the trim tool to trim this extra
10:02
geometry and now to close our profile here we will create an arc which will be
10:08
equal to our projected diameter so here I will select a three-point Arc and I
10:16
will uh create an approximate Arc and now select this construction diameter
10:22
and our newly created 3o AR and made it equal so you can can see that uh our uh
10:31
sketch is fully constrained and now we will come out of the
10:37
sketch let's switch to the flat
10:42
lines and now we will uh extrude this profile up to this phas so we will
10:48
select the sketch and click on the pad and from here we will select up to
10:54
phase and select this phase and say okay
10:59
so you can see that a rib has been created now there is a
11:05
cut so we will on our origin
11:11
plane so we will select this mid plane which is y z to create our cut profile
11:22
at this locations so I have selected the plane and now I will click on the sketch
11:29
and and uh from here I will switch to the wireframe and
11:35
now I will click on the project geometry I will project this and this
11:42
and here I will uh create a triangle to remove the material so select the line
11:50
tool draw the horizontal line draw the vertical line now
11:59
if you see that uh I cannot move it because it is got constrained so this is
12:04
the constraint I will delete it so that uh I can move it here and I will select
12:12
this and this and add a coincidence now let's uh create our triangle by joining this
12:21
point and this point and now if you see
12:29
this is the dimension 35 so we will from this point to this
12:35
point select smart Dimension and uh give it
12:43
35 and here I will select this point at this
12:48
point and add a coincidence now click on
12:55
close of the origin plane
13:01
now we can clearly see the sketch is on our mid plane select the sketch click on
13:09
the extrude cut and from here say it through
13:15
all symmetric to the plane so cut is
13:20
created now as we have a created a cut at the mid so here material is also got
13:28
remove moved now we will create a sketch on this phas and create the profile and
13:36
we will extrude it to the this surface so that material get fill up in this
13:42
area so for this we will uh select this face and uh click on the
13:51
sketch now we will uh rotate our
13:57
model and here we will again use the project geometry we will project this uh
14:05
radius and this and now I will switch to the rear view and
14:13
from here I will switch to the wireframe
14:18
now let's select a line tool and create a
14:24
line and uh then select a threep point Arc select this and
14:30
this and uh made it equal so our sketch
14:36
is fully constrain now I will switch to the flat lines so
14:42
that you can clearly see
14:47
it so this is our sketch now we will select our sketch and uh click on the
14:56
extrude and from here I will select up to phas and I will select this phase so you
15:03
can see that uh material got fill up here say
15:09
okay now we will uh move to the next
15:14
feature which is if you see here in a section A there is a rectangular cut
15:21
which we can see so let's uh save our model now
15:28
switch to the isometric View and now we will uh rotate our model and select this
15:34
bottom phas and click on the sketch switch to the isometric View and
15:43
now we will uh project this age click on the project
15:49
geometry project this age and now here I will select a rectangle and
15:58
uh create a rectangle and width of this rectangle
16:03
should be symmetric to this
16:09
axis let's switch to the flat line so that
16:15
uh you can clearly see it here now I will select the symmetricity
16:22
select this point this point and this axis so this
16:28
is symmetry now I will select smart Dimensions give it
16:35
100 and from this line to this one is of
16:41
15 mm and this is of the
16:52
48 close it and now we will create a cut
16:57
of 30 mm select the sketch click on uh
17:03
extrude and say it 30
17:10
mm now you can see that cut has been created but if you see in the section AA
17:18
there is a no material inside which means that uh we have to create a
17:24
revolve cut profile so for this uh we will on the origin
17:30
plane and we will select this YZ plane and
17:36
click on the sketch now we will uh switch to the
17:42
wireframe view and uh we will uh create the Revol cut
17:49
profile so first thing we will create a
17:55
line and we will make this line as a construction and position of this line
18:02
from the origin is of uh 95 so select this and this and give it a
18:11
95 and now we will uh click on Project geometry
18:17
and project this and uh this and we will select a polyline
18:24
tool to create our profile
18:29
so we will first create a rough profile and then we will constrain
18:40
it so this is the polyline tool which we have created and
18:47
now let's uh create a vertical line and close our
18:53
profile so we will uh select a line tool create a EXA line and
19:01
now I will uh select a line tool and join these two points and
19:08
select it and uh made
19:15
it so here we will make it
19:23
vertical and now select this point and this point and
19:30
add coincidence so our profile is uh closed now we will uh give the
19:38
dimensions so select smart Dimension select this and this is the
19:44
45 and from same point to this point is of uh
19:52
50 and uh this is of 16 mm and this is of uh
20:02
48 and this of 20
20:07
mm let's move the dimensions so that uh you can clearly see it and you can read
20:14
this Dimension here now we will uh close
20:20
it off the origin plane and now we will remove the material so we will use this
20:27
uh group feature and here fread automatically took the access
20:34
so we have to define the our exis so we will select here and click on select
20:41
reference and we will select this line and say
20:46
okay so you can see that uh group feature is
20:54
created and now let's uh mve to the next step
20:59
next step is to create a rectangular cut
21:04
so we will select this pH and click on the sketch we will uh switch to the
21:12
wireframe and click on the project geometry project this vertical
21:19
edges and
21:25
now we will give the height which is off of 16 mm select this and
21:32
uh give it a 16 mm click on close and from
21:41
here switch to the flat lines and now here we will remove the material to the
21:48
distance of a 5 mm select the sketch click on the
21:53
cut and Define the depth 5 mm
21:59
and now if you see in a isometric view here is a cut so we will select this stop face and
22:07
click on the sketch so we are on the right
22:14
orientation now we will select a rectangle and create a rectangle and uh we will make this point
22:22
symmetric so click on the symmetricity constraint select this point this point
22:27
and this axis and select a smart Dimension and give it a
22:35
60 and this height is of uh 30
22:41
mm click on close now select the sketch click on
22:47
Cut and from here Define it through all say
22:54
okay so we can see that overall shape has been a achieved here now we will
23:01
proceed to The Next Step which is to add a material at the
23:09
top so for this we require a datm
23:15
plane and here from the bottom bottom of the plane
23:21
we will create a datm plane at a distance of 120
23:31
8 to the distance of uh 128 and you can see that
23:46
uh now we will uh create
23:51
this boss here so for this we require a data plane
23:57
so we will select this uh bottom plane and click on the datm plane here
24:06
and create a datm plane at a distance of 128 and say okay and now we will off the
24:14
origin plane now switch to the isometric View and we will create our sketch on
24:21
this datm plane so select the sketch and click on the sketch and now here we will switch to
24:29
the wireframe and let's also hide this datm plane now click on the circle and create
24:38
a circle on this axis and here we will project this
24:44
Edge so that we can Define this position select smart Dimension select this and
24:52
this and give it 32 and here
24:59
this diameter is off 22 now we will uh close it and here we
25:07
will uh switch to the flat lines view now we
25:13
can clearly see the sketch so first we will select the sketch and click on the
25:21
pad and here we can see that uh we are
25:27
not seeing our pad add so click on here reverse and from here select up to phase
25:34
and select this phase so you can see that pad has been
25:40
created with respect to our isometric view
25:46
now we will uh create this uh counter board holes on a base
25:52
plate so for this we will select the phase and click on the sketch
25:58
and uh we will switch to the wireframe view and now
26:07
here I will uh select a twoo rectangle and uh create a rectangle now I will uh
26:16
select all the lines of a rectangle from draging from right to left and make it
26:27
construction and now we will uh create four
26:40
circles on these four points so select the
26:45
circle and create a four circles at Four
26:56
Corners and now now we will Define the diameter so this is the counter board
27:03
holes of Dia 14 through so select a smart Dimension and give it
27:11
14 and now press control key and select all the
27:18
circles and made it equal now we have to define the
27:24
positions select smart Dimension from this this to this is of 18
27:33
mm and Pitch is of
27:41
104 and this is the
27:49
134 now let's see what is the unconstraint so here this 104 is of a
27:57
symmetric so we will click on the symmetricity select this point this point and this
28:04
axis so our hole is created
28:11
now we will create a counter B holes and here we will use the whole visard tool
28:17
so click on the whole visard option and our through di is of
28:25
14 and depth is of for through all and now here we will select a counter board
28:32
and counter board is of a 22 and depth is of three so some of the
28:39
dimension is uh not given in this drawing so we will assume those
28:45
dimensions and we will uh create a lookl like model our main concern is to
28:51
understand the feature of a freeat like how pad extrude ho fillet
28:57
work box now I will say okay now if you see here there is a
29:07
tapped tole whose position is not given but we
29:14
will do the approximate so select the this front face and click on the
29:20
sketch and now we will project this
29:26
diameter and and here we will select a
29:31
rectangle and create a rectangle and here we will switch to the
29:38
wireframe and now we will do the same thing we will select all and made it
29:45
construction and here we will create a hole of a diameter 6 because we will
29:53
create a tapped hole of M6 but before that
29:58
Let's uh make it symmetric so we will click on the symmetricity select this
30:04
point this point and this origin and uh vertical Dimension is of
30:12
100 and this is also 100 so we will make it equal now we will create a four
30:19
Circle at Four Corner points of this Square so select the
30:25
circle and uh create for
30:36
Circle and now we will uh select a smart Dimension
30:42
and give it six and now press the control key select this this this
30:50
and this and uh made it equal now close
30:55
it now here we will switch to the flat
31:02
lines which is our shaded View and now here we will create a M6 tapped tole
31:11
select the sketch even though detail is not given here so we will click on the whole
31:17
Wizard and here we will select the isometric regular
31:22
profile and from here I will Define the size of M6
31:28
and uh depth I will give the 8 mm and say okay now we will switch to
31:37
the top view and rotate our model to check this tapped
31:42
hole to do that we will switch to the wireframe and we can clearly see
31:49
here the tapped tole is
31:54
created now let's uh move to the next feature feature our next feature is to
32:00
uh provide the required flet as our model is uh approximately done so we
32:08
will provide a fillet at a ages so click on the fillet and
32:16
uh once you select the age it will be get added here so I will select this age
32:22
this age this age
32:28
and this age and provide the fillet of 5
32:34
mm say okay so here this fillet is not taking
32:39
so we will uh remove it and we will say
32:47
okay so you can see that fillet has been
32:53
created now let's provide the fillet on the other
33:02
side so click on the fillet select
33:08
uh this H this H this
33:19
H this this and uh this and let's give the
33:27
size of for
33:32
5mm so you can see that fillet has been
33:39
created so here if you see there is uh one
33:45
hole which is of uh diameter 10 so we will create that hole on this face so
33:53
select the phase and uh click on the sketch switch to the isometric View and
33:59
uh we will simply project this diameter so that we can get a center to Define
34:07
our diameter so here I will uh create a circle select smart
34:13
Dimension and uh give it a diameter 10 and uh click on
34:19
close and now we will uh simply create a
34:25
cut and we will uh Define the
34:31
hole so that it opens in this open area
34:36
so just I will increase the value so that it will come
34:47
out okay so here you can see that uh hole has came out here
35:02
let's say okay you can keep it
35:08
some minimum distance like a 20 mm and say
35:18
okay now press zero for isometric view now you can see that uh here at 4
35:27
edges there is a radius of r18 so we will again select a
35:33
fillet and uh we will select this Edge this
35:41
Edge this Edge and this hede and give the fillet of 88
35:48
mm say okay now press zero so we have a
35:58
successfully made this model in freead with with the help of a dimension given
36:03
in orthographic View and our view is matching with the isometric view now we
36:09
will give the same color with respect to this isometric view so we will select the last feature go to the
36:16
appearances and here we will see the custom appearances option and here is a
36:23
diffuse color and here I will select
36:29
my
36:34
color and I will move
36:40
it so more or less it is a same color and now I will
36:49
uh close it it is not exact color Let's uh again
36:56
change it go to the princess
37:15
here say okay and close it so more or less we have
37:24
given the color symmetry to the our isometric view so this is all
37:31
about this tutorial and in this tutorial we have learned the fundamentals of a
37:37
part design in freead and we have used the so many features here like a whole
37:43
data plan Groove mirror Etc so this is all about this tutorial thank you for
37:50
watching and thank you for your valuable time
