hello friends welcome to Fria tutorial and in this tutorial we will model this part and you can see that I have already
0:09
modeled it with respect to the orthographic uh view and uh you can also
0:15
see that uh our uh frecad model is uh matching
0:20
with the reference isometric view we will uh create this part from the
0:26
scratch in frecad and for this tutorial I am using the frecad version 1.0 so you
0:34
must have at least fread version 1.0 or higher for this
0:40
tutorial now I will close this file and we will create this part from the scratch
0:47
so here I have created a new file and uh part design workbench is active and
0:54
now I will create my first sketch so for the first sketch we will create this uh
1:02
circular profile first and for that uh we requires a body
1:07
so we will insert our body and on this origin plane and I will select this top
1:13
plane and click on the sketch and now I will hide this origin plane
1:20
and select a circle tool create a
1:29
circle and now provide the dimension which is of 100 mm which we can see here
1:37
select a smart dimension and provide this 100 mm
1:44
and now we will extrude it to the distance of a 40 mm if you see in a side view so we can
1:50
see here dimension 40 and now I will come out of the sketch select
1:56
the sketch click on the pad and uh give the distance 40 but here
2:04
we will make our part symmetric because we want our mid plane at the mid and uh
2:12
we have to create this uh both the faces so here click on symmetric to the plane
2:19
and say okay now once you've made it symmetric to the plane so
2:25
we can see that our uh top plane is at the mid and uh this two features will come
2:33
on this plane now I will off the plane and we will move to the next feature
2:41
so as we have uh made the symmetric so we will select
2:46
this top plane and click on the sketch and uh
2:52
here we will uh create this profile and here we will uh create this
2:59
outer boundary and then we will extrude it and
3:05
after that we will create a cut so let's read the dimensions and uh create this
3:11
sketch so I will off the origin plane and for better visibility I will switch
3:17
to the wireframe from here or shortcut is V3 so we can press the shortcut as
3:27
well now for right orientation I will go to the isometric view and select this
3:34
top and now I will create the profile so first thing we will do is to create two
3:42
diameter which will be the construction geometry and we will first fix that and
3:48
after that so this diameter is on the same axis with origin so here I will
3:56
create a circle and uh center to center distance is 110 so I will select a smart
4:04
dimension and provide 110 and here we can see that this
4:11
diameter is a 60 so provide the diameter and now we
4:16
will create this circle and here we can see the angle of
4:24
51° but before that let's select this diameter and made it construction and
4:29
now first we will create a
4:34
line and uh select the smart dimension and uh provide this angle which is of
4:43
51° and uh we will make it a construction and alliance dimension is
4:49
of 127 so we will select our dimension and uh provide
4:58
127 and here I will move this angle and now here
5:04
I will create a
5:11
circle now here instead of giving a diameter dimensions I will select this
5:18
and this and uh made it equal and at the same times I will make it
5:24
construction so this is the positions and around this we will uh create our
5:33
profile so here we see that here is a radius of
5:38
R12 so we will create first four tangent line and uh we will also project this
5:47
outer diameter click on project geometry and project this outer diameter and now
5:53
we will create four tangent line so let's first create two inclined line on
6:00
both the side and select this and this and uh provide the tangency
6:08
select this and this and provide a tangency let's move it to the
6:16
here and
6:22
now here is a tangent and tangent now we will uh use the trim
6:30
tool trim the extra line and
6:35
here we will provide the tangency so we will select this line and arc and uh
6:42
provide the tangent and uh click on the
6:49
trim and now here if you see if you move this
6:56
point it is uh fully constrained and we will keep this point as a free and now
7:05
we will uh draw the tangent line on both
7:10
the side to this diameter so create a two incline line and now select this and
7:18
this and add a tangent select this and this and add a tangent and here I will extend this line
7:26
and select this and this and add a tangent
7:33
now here I will select this point and this point and add a coincidence
7:40
constraint and here same way we will uh trim the extra geometry trim this
7:46
extended line now make this normal same way also
7:53
trim here now we will uh close our
7:59
profile so for this let's uh create a threepoint
8:05
arc go here and select a threepoint arc select uh these two points and uh create
8:14
a arc and here provide the tangency and
8:21
uh make the center coincidence and let's move this point
8:28
same way we will create a threepoint arc here and uh before
8:37
that so here let's uh create an arc and then we will constrain
8:45
it now first thing which I will do is to make the center coincidence and now this
8:53
point is a free so we will uh give one reference
9:01
dimension between this and this and make it a reference and we will
9:11
make this end and this angle same so here we will give the same
9:16
angle 9 0606
9:23
7 and here we will uh use the fillet tool to create a
9:30
fillet so click on the fillet and select this and this we will constraint this
9:36
radius with R12 select it and uh provide radius of
9:48
R12 like here we have given the angle and now here we will do the same thing
9:54
we will uh select the angular dimension and uh give the dimension and
10:01
make it reference so it is a 10.4757 we will do the same
10:07
thing and we will give it uh 10.47 57 so our uh sketch is fully
10:18
constrained but here is a one loop is open so we will uh create a threepoint
10:26
arc select this point this point and select this and this and add a tangent
10:34
so our sketch is fully constrained and now we will come out of the sketch and
10:41
here we will create the pad of a 22 mm so here is a dimension is given and both
10:48
the side it is of a 22 so select the sketch click on the
10:55
pad and here we will uh make it symmetric to the
11:01
plane and uh give it a dimensions 22 and say
11:09
okay now let's uh move to the next feature in the next feature we will uh
11:16
create this cut which we can see in isometric so let's switch to the
11:23
isometric and select this face and click on the sketch and now
11:28
here I will project this radius click on project geometry and project this radius
11:34
and this radius as well and now we will uh create a
11:41
construction diameter which will be equal to our projected radius select this and this
11:48
and uh say okay select it and uh made it construction same
11:58
way we will uh switch to the wireframe at this location this is the
12:04
diameter already projected so we do not need a construction geometry and now if
12:09
you see the wall thickness so here 10 mm is given so for this we will create a
12:16
wall thickness 10 mm from this age from this edge and this edge so let's uh
12:23
click on project geometry and project this edge and this edge and now here we
12:30
will create a two arc and join with the
12:35
line so let's select the threepoint arc and create one arc same way again select
12:44
a threepoint arc and uh create a threepoint arc and
12:50
now we will uh create a line by joining these two points select the line tool
12:55
select this and this and join it select this and uh this join it and
13:03
now we will select this and this and add a parallel constraint similarly this and
13:09
this and add a parallel constraint and now we will uh select a smart
13:18
dimension and uh provide the 10 mm select this and
13:24
this and uh provide 10 mm and now
13:31
here here is R5 is a fillet so we will also create this
13:37
fillet inside of this sketch
13:43
so let's select a fillet tool create a
13:50
fillet select this and this so four fillet is added on the four corners and
13:57
now we will select a smart dimension and make one of the fillet and
14:05
we will select this fillet and press the control key and uh select all four
14:11
fillets and uh made it equal so now let's see what is the
14:17
unconstraint let's select the radius so here we can see that center is not
14:23
coincidence so we will uh rotate
14:29
it and we will select this and this and uh made it
14:36
equal and select the center and add a coincidence
14:42
similarly select this radius and here we will first made it uh
14:51
equal and let's select the center and made it
15:01
coincidence so our sketch is fully constrained here you can do one thing you can create a rough profile add a
15:08
fillet and uh then add the dimensions so we will come out of the it we will uh
15:15
create uh cut tool and give the depth 6
15:22
mm and now say okay
15:30
now we will create one more cut on the other side with the same method we will
15:37
select the face and click on the sketch and here we will same way project this
15:43
uh outer radius select a circle tool and create a circle and here we will make it
15:51
as a construction circle and we will again project this outer one and uh we
15:58
will switch to the wireframe view for uh better visibility and here we will uh select
16:07
threepoint arc tool and uh create an arc on here
16:15
and here and same way we will
16:21
uh move this point move this point and uh create a
16:30
line select this and select uh this and
16:36
now let's add the four fillet of
16:42
R5 so why I'm making the fillet in inside the sketch because uh freet
16:48
fillet issue is very common so avoid that i am creating the fillet inside the
16:55
sketch but uh you can also give this fillets at the end now I will select a
17:01
fillet tool and select this line and arc select this line and arc select this
17:07
line and arc here and here now wall
17:12
thickness is 10 mm from the age so we will click on the project
17:20
geometry and uh make it parallel select it and uh select it and uh make it
17:27
parallel and now let's constrain one of the
17:35
radius make it 5 mm and now let's select
17:41
uh all the radius and
17:46
uh made it equal now here center got shifted so we
17:52
will add and make it a coincidence and then we will made it
17:58
equal same way we will select this and this and add it equal and we will add a
18:09
coincident now let's add the wall thickness of a 10 mm select the
18:16
dimension and give it a 10 mm similarly select this and
18:23
this and give it a 10 mm so you can see that uh sketch is fully constrained and
18:31
now we will create a cut of a 6
18:39
mm say okay now this cuts which we see
18:45
on our top view is the same on the bottom side so we will select this both
18:50
the pocket and click on the mirror option and from here we will uh click on the
18:56
select reference and select this our mid plane and we can see that uh it is
19:03
successfully mirror on the other side and say
19:09
okay now here we see the
19:17
hole which is 4 mm depth so we will uh create this
19:25
hole so for this we will select this phase and click on the sketch and now
19:31
here we can see the distance is a 20 mm so on the same axis here so we will
19:38
select a circle and uh create a circle and its diameter is of 44 which
19:45
we can see here select a smart dimension and provide the diameter
19:52
44 and uh again select a smart dimension and from center to center is of uh 20
20:04
mm now let's move the dimension this is the 20 and this is the 44 come out of
20:11
the sketch and make this 4 mm depth cut select the sketch and click on the pocket
20:21
tool and here give the depth 4 mm and say okay
20:28
now we will uh mirror this cut on the other side because we can see that 4 mm
20:36
depth at the top and bottom so select the pocket and uh click on the mirror
20:43
tool and from here click on the select reference and uh select this top
20:51
plane and say okay
20:56
now press zero and now we will create a
21:01
hole and we will polar pattern
21:09
it let's uh select this face and uh click on the sketch and now here we will uh switch to
21:18
the wireframe view and we will project this diameter
21:23
because we are going to make this polar pattern with respect to axis of our cut
21:31
so click on the project geometry and project it and here we can see that a
21:37
PCD of 30 mm so we will select a circle
21:43
select smart dimension make it 30 and uh we will make
21:51
it a construction because it is a PCD diameter and now we will create this hole which will be the coincidence on
21:58
this diameter and this axis so we will select a circle and
22:04
create a circle here and uh this is of a diameter 8
22:10
mm provided 8 mm and now we will make first coincident with the axis and then
22:18
other coincidence on this arc so this is
22:24
the sketch is fully constrained and now this is the simple drill hole so I am
22:30
going to make with the cut but you can also use the whole wizard tool
22:36
now I will say it through all and say okay now we will polar
22:43
pattern it so select the pocket and click on the polar
22:49
pattern and now here number of hole is of seven so give
22:56
the quantity seven and here we will select uh
23:01
reference and we will select this
23:07
diameter and uh say okay so you can see that the polar pattern hole is created
23:14
now we will create this cut here and for this we will uh select this
23:20
top face and click on the sketch and now here we will uh read the
23:27
drawing so here we can see the dimensions 10 mm so let's uh first switch to the
23:34
wireframe view and uh draw a horizontal line and now give the 5 mm dimension
23:42
from the center select smart dimension select this axis and point and give the
23:48
5 mm and now we will create a threepoint arc
23:55
which will be concentric to this diameter so for this uh I will uh select
24:02
diameter and now I will uh select a threepoint arc and uh create an
24:10
arc and uh let's
24:15
uh let's make a coincidence and now this is of R 25 so select
24:23
dimension and provide it 25 and now we will create one more arc
24:31
select a threepoint arc and uh create a arc and uh this center will be
24:38
coincident to our origin and uh set it coincidence
24:45
now let's uh position it and
24:51
now we will uh provide the radius we will uh create a
24:57
threepoint arc here and uh we will create a fillet here so let's first
25:02
create a fillet between this and uh let's create a threepoint arc here
25:12
and let's provide a tangency set tangent set uh tangent and
25:21
now select a radial dimension constraint radius and uh provide a 5 mm and now
25:30
select this and uh this and uh made it equal and here also provide the
25:39
fillet select these LEDs and simply select this radius and this radius and
25:46
made it equal and now let's see what is the unconstrain so
25:53
if we move it so we can see that uh it is a
25:59
freely to move so now here if you see the wall thickness is of a 10 mm is given and
26:06
this is of a diameter 100 so radius will be 50 so this outer radius will be of 40
26:14
mm so select the radius tool and provide the 40 mm so that we get
26:21
a 10 mm wall thickness and now click on the close and uh switch to
26:28
the flat lines view and now we will create a
26:33
cut which will be the through wall
26:40
now select the sketch and uh click on the cut because this cut is through all
26:46
and from here set it through all and say okay and now select the pocket and
26:53
select the mirror and here if you see we will use
26:59
this exit plane
27:06
select reference and select this exit plane and uh say
27:12
okay now let's uh move to the next feature next feature is to create a
27:20
hole select the face and click on the sketch and now here we can see the
27:27
diameter 30 we will click on the project geometry and uh select a
27:33
circle select the smart dimension set it 30 and click on close
27:41
select the sketch click on cut and uh set it through all so here it
27:49
is a plain drill hole that's why I have used the cut tool you can use the hole
27:54
as well and now same way we will create this diameter 21 hole so select
28:02
the face and click on the sketch click on the project
28:07
geometry select the circle and create a circle and uh
28:13
provide this 21 and uh click on close select the
28:19
sketch click on cut and uh set it through all
28:32
now this completes our model and there are some common note about the fillet if
28:38
you see here so there is a R2 fillet on the both the side so we will uh click on
28:45
the fillet tool and uh select this edge select uh this edge and
28:53
uh select this edge so here is a face is selected
28:59
remove it select the H and select the H and
29:05
provide here fillet of
29:14
R2 now press zero for isometric and let's switch to the
29:20
isometric of our drawing so this completes our model and we have
29:26
successfully modeled this part from a scratch by referring the dimension of
29:33
sections and top view and uh we have successfully converted and if you want
29:39
to apply the colors to the part like our reference color go to the
29:47
appearances and uh from here go to the custom appearances and here you can uh
29:54
choose your desired color so here I'm giving the approximate
30:00
color say okay say close
30:06
so this is all about this tutorial thank you for watching and thank you for your
30:11
valuable time
