hello friends welcome to free tutorial and in this tutorial we will model this part and uh you can see that uh I have
0:08
already modeled it and uh it is matching with the isometric view of our uh
0:13
reference drawing i will show you how to model this part and uh I will show you how to
0:22
read the dimension of this orthographic and we will create this part this
0:28
tutorial is uh very simple and uh this is designed for the beginner user of a
0:33
free CAD now I will uh close this file and create a new file and I will uh show
0:41
you from the scratch if you want to learn free CAD from the scratch then you can buy my
0:48
complete free CAD course from zero to expert this course is designed from the
0:55
scratch to the advanced tools and advanced modeling in free so here if you
1:02
visit this course page then detailed course description is given and what you
1:07
will learn user will be easily to switch from a paid software to the open-source
1:13
fread generating 3D model and skillfully design mechanical parts
1:19
master Frecad you will acquire the proficiency in a tools function and
1:26
interface and uh you can create a complex model in a free CAD and hands-on
1:33
project exposure and uh if you scroll down you will find the
1:39
course content like in the first sections I have a explain the free CAD
1:45
introduction and what is the new feature in 1.0 0 so you can see the lecture
1:51
inside this section second section is to getting started with the free CAD 1.0
1:57
and how you can customize and third section is a fundamental of a sketching to understand
2:04
the sketching and constraining in free CADs fourth section is a fundamental of a
2:11
part design where I have a detail explain the all essential tools of a
2:17
part modeling then fifth one is dedicated to the mechanical part
2:22
modeling and here I have took the practical examples of a mechanical part
2:29
like a gear cover offset guide anchor bracket bend pipe socket form
2:34
lower lever bracket etc next one is a mixed part modeling in frecad where I
2:42
took the example like a modeling of a coffee mug smartphone etc next is a working with a frecad
2:49
assembly and here I have explain how to create an assembly in freead next
2:55
section is a free CAD drawing where I have a explain how to create a technical
3:03
drawings in a free CAD and here I have a manufacturing point of view i have
3:08
included the topic like how to create part list add welding add surface finish symbol how to add the GD&
3:16
next one is a advanced tutorial in FRECAD where I have also took the FE
3:22
analysis in Frecad 3D printing and uh how to use
3:27
the Python tools in freead next one is a productivity enhancement tool in frecad
3:34
where I have explained many tools in a freead which will save your time
3:41
and you can create the complex model or
3:46
a complex task within a less span of a time by using this productivity
3:52
enhancement tool next section is advanced part modeling in freead here I
3:58
have a took the complex example like a gearbox housing enclosures and a cover
4:05
shaft covers so these are the complex part modeling in a free CAD next one is
4:11
a advanced drafting and detailing in a free CAD here I have took the complex
4:17
drawings and I have created the model and also created the drawing and these
4:23
are the lengthy tutorials of more than 30 minutes 40 minutes or 45 minutes and
4:30
uh last one is a projects on a free where I have took the example of a clamp
4:38
modeling and assembly in a free cat from the modeling to the assembly
4:44
everything is included under the project on a free modeling to assembly
4:52

4:57
is the my course complete free course from zero to expert go inside and uh the
5:06
sections I have shown you on my Kofi shop page so exactly same lectures under
5:15
the section is created for example section one is a introductions to free
5:22
1.0 and what is new in a freead 1.0 so if you go to the section one so there
5:29
are the 18 lectures and if you go inside of this sections one you will find the
5:35

7:16
so please check out my course on uh free CAD from uh 02 expert and now we will
7:26
come back to our tutorial so here I have created a new file and uh
7:33
now I will insert my body and uh I will create a sketch and
7:39
now as per the part orientation we will uh select this YZ
7:45
plane to create our waist profile so
7:52
select the plane and now we will uh read the dimensions
7:58
so here I will select a rectangle tool and I will create a rectangle and now we
8:05
will make it symmetric so here I will use the symmetricity
8:11
constraint and uh make it symmetric and now let's give the
8:17
dimensions select this horizontal dimension provide 54 and uh select this
8:24
vertical dimension and provide 128
8:29
so our uh sketch is fully constrained and now I will close
8:35
it and now we will uh create the pad of 40 mm if you see in a side view here we
8:44
can see so we will uh select the sketch click on the pad and here we will click
8:50
on symmetric to the plane and uh provide the 40
8:58
mm now we will create our next feature so if you see the isometric view so here
9:05
we have a circular profile and here is a one more pad feature which is a similar
9:11
on the other side so we will create it on the left hand side and we will use the mid plane to mirror on the other
9:18
side so let's select this face and click on the sketch and here our model is
9:24
rotated so we will rotate to the right orientation and now let's uh click on
9:31
the circle tool and create a circle select a diameter option and provide it
9:36
a 30 mm and now close it and select the
9:44
sketch click on the pad and uh provide the value of uh 37
9:51
mm you can find out this distance with a
9:57
reference dimension shown in a front and top view
10:02
now let's uh create this profile and for this we will
10:10
uh select the face and uh click on the
10:17
sketch now let's uh rotate our model and now here we will switch to the wireframe
10:25
view and let's uh start creating our sketch so first thing we will do is to
10:32
select a circle tool and we will create a circle and if you see our drawing so
10:38
this is the diameter 50 so we will create a circle and uh constrain it with
10:44
the diameter 50 and uh select it and uh make
10:50
it construction and now we will uh create a threepoint arc
10:59
on the both the sides so let's uh select a threepoint arc
11:05
tool and here let's create a threepoint arc and
11:11
uh select it this and this and add a coincidence constraint and now here we
11:19
will uh constrain this point so for this we
11:25
will uh select a line tool and uh create a line and uh we will make
11:34
it coincidence relation with our construction diameter and uh make it a
11:41
coincidence so here select a coincidence select the diameter and this point
11:48
similarly create one more line and uh add it coincidence or we can
11:55
use the trim tool as well and now select this and this and add a
12:03
coincidence select this and this and add a coincidence now here angle is given is
12:11
of 40° so this will be our uh construction line
12:16
and we will select the smart dimension select this and this and here we will
12:22
provide the 20° let's give the first dimension on
12:29
the left hand side and give it a 20
12:36
and now we will uh make this
12:42
angle dependent on this so here we will give the name as it is a angle dimension
12:50
so we will represent a for angle and give the 20 so angle 20° say okay and
12:58
now we will uh select a smart dimension and give the
13:03
angle as if I change this angle that should be changed so we will link it so
13:10
here you will see the option of equation and here type
13:18
constraint once you select this fread will automatically show you so here I
13:24
want to link with the A20 which is the angular 20 dimension select it so once
13:30
it is successful you will see the result 20° and say okay now you can see that uh this is a
13:38
dependent dimension on this so if I change this angle to 30 then this will
13:44
be changed so this is how you can link the dimension and if I again make it uh
13:50
20 it will be get 20 now constraint this arc so for
13:58
this we will uh provide the radial dimension as it is a diameter 36 which
14:06
is shown here so we will uh select a smart dimension and uh provide
14:14
it 36 so here R36 is a diameter so here
14:20
we will make it uh 18 mm so you can see that uh we have
14:25
defined the radius we have defined these two points so that our this first arc is got fully constrained now we will create
14:34
this two arc of R8 so we will uh select a threepoint arc and uh create a arc and
14:43
provide here tangency relation tangent and we will create one
14:50
more arc here select a three point and uh select this and
14:57
this and uh say the tangent and
15:03
now r8 is given so we will select dimension and uh provide it R8 now here
15:12
we can do the two things we can link the dimensions like this or we can select
15:19
both and uh made it equal so once I change this value this
15:24
and this having the equal relation so if I modify this radius this will be changed so you can see that all three
15:31
arc are the constraint and now we will create a similar profile on the other
15:39
side and now here you might think that we can why we cannot use the mirror so
15:47
if I select this and uh this and use the mirror tool it will be get mirror but
15:53
problem with this mirror that uh it does
15:59
not make a relations like the relations the coincident tangent is given here if
16:04
I mirror it yeah but uh if I try to move it so you can see that center is not a
16:11
coincidence so we need to coincidences if we are using the mirror tool so as of
16:18
now this is a problem with the frecad mirror tool until and unless we have to wait that uh
16:26
apart from the mirroring the profile free also apply the constraint here so
16:33
because of this issue we will create our profile from the scratch like we have
16:38
created on this side so let's uh select a threepoint arc and we will uh create a
16:45
arc and here I will uh make it uh
16:51
coincidence and now we will move it and we will similar
16:57
create a two line of uh 20° on the bottom side so select a line tool and uh
17:07
create a line and now select the both and
17:14
uh make it a construction and here we will use the trim
17:20
tool let's trim the extra geometry and now select this and this and add a
17:27
coincidence select this and this and add a coincidence now here we will uh
17:35
provide the dimensions and here we will link the
17:42
dimensions go to the equation option and type the constraints and here we will see the A20
17:50
say okay so we will do the same thing here and we
17:56
will add a dimension of uh same and here we will go to the equations and
18:04
now type constraint and here is a
18:10
20 say okay so now we have the three dependent dimension on this 20 if I make
18:18
it a 25 so everything will be 25 so try
18:24
to link the dimension as much as possible if if a profile is like a
18:33
mirror so here is a mirror profile so now instead of giving a
18:39
dimensions to this radius I will uh simply select the both and uh made it
18:48
equal so you can see the constraint and now we will create these two
18:54
radius so select a threepoint arc select this and this and uh same on the other
19:04
side and now provide the
19:10
tangency select this and this and provide the tangency and here we will use the same method instead of providing
19:18
dimension we will use the equal so try to avoid the dimensions and uh
19:26
try to add the relation as much as possible like equal
19:31
symmetricity parity and now here we have created the
19:38
profile and now we will uh project this age which we are seeing
19:45
so let's uh go to the project geometry and project these two edges and now here
19:51
I will uh draw two vertical line on the both the
19:56
side and now here I will select this and this and add a
20:03
coincidence and uh select this and uh this and add a
20:10
coincidence and now let's select this point and this point add a coincidence
20:16
you can also use the trim option now I will make it
20:21
coincidence similarly here make it a coincidence and uh make it a
20:29
coincidence this is also constraint now we will uh select a threepoint arc and
20:36
uh create arc here and here I will place my arc very close to this construction
20:44
diameter and uh here I will use the tangency you can also use the equal
20:50
constraint now again I will select a threepoint arc select this and this and
20:57
place it and uh make it a tangent now same on the bottom side we will
21:05
do select the threepoint arc and
21:11
uh provide the tangency similarly on the this
21:17
side select it and uh here let's make it a tangent
21:29
select this and this and uh add a tangent so you can see that uh our
21:36
sketch is fully constrained and now we will close it and let's switch to the flat
21:47
lines and now create a pad and provide the value 12
21:55
mm say okay now we will mirror this uh pad one and pad 002 so here order of
22:03
selection is very important while mirroring so press control key and press
22:09
the first feature pad one and then press the control key and click on the pad 002
22:16
and now click on the mirror now here logic is that uh order of selection is
22:22
important so it will be get added in a same way and now here we will click on
22:28
the select reference and here we wanted to define our reference along the XZ
22:34
plane so you can see that our feature is mirror on the other
22:43
sides now we will uh provide the fillet as a isometric view we can see that
22:49
there are the four fillet at four corners whose detail we can find here in
22:55
a front view so we can see that there is a fillet of R14 so we will click on the fillet tool
23:03
and here we will select the edges and we will add the ages
23:11
so best part with the fillet is that uh once we select the age it is get
23:18
added here and we can uh remove if any age we have are wrongly
23:25
selected so here now provide the value 14 mm and say okay so our fillet is created
23:35
and now we will create this cut profile so for this we will uh simply select
23:42
this uh face and uh click on the sketch and here we will uh switch to the
23:49
wireframe view for better sketching and now here I will use the polyline tool to
23:58
create a rough profile
24:09
let's create a rough profile and then we will provide the relevant
24:26
constraint and now we will provide the relevant constraint so starting from the one end
24:34
so this line is not vertical i will select it and make it vertical so here
24:40
it is horizontal it is vertical this is horizontal vertical so we have attached all the
24:48
relations and now let's define the positions of this line and for this we
24:54
will click on the project geometry and project this age select a smart dimension select this point and this
25:02
point and provide the dimension 8 mm which we can see here and
25:12
now this to this is of a 70 so we will select the line tool and uh provide it
25:20
70 mm and here we will make this 70 mm
25:25
dimension symmetric to the axis so we will click on the symmetricity
25:32
constraint click on constraint symmetric select this point this point and the
25:38
axis so now this has got a constraint and now we will uh click on the project
25:46
geometry options so let's click on the project
25:52
geometry and also project this age
25:57
so now here we will select the smart dimension and uh provide the dimension
26:04
of 38 and uh here we will use the symmetricity constraint select this and
26:11
this and set axis and now we will uh select this and this and
26:18
uh made it equal and uh set it horizontal so here
26:24
sometimes it took the wrong constraint so we will specific select it and
26:29
provide the horizontal and now let's select this point and this
26:35
point and provide the horizontal constraint and now let's define this point to the 40 mm
26:44
from the edge select this and this and
26:49
provide 40 mm and now let's see what is the
26:57
unconstrained so we can see that this is the
27:04
unconstrained and this line is constraint so we will select this and this and uh made it equal so here we are
27:12
seeing the conflict so we will uh make it uh control Z and now we have a four
27:19
degree of freedom which we can see that and we will make it
27:25
zero so here bottom position is of 8 mm same way we will uh define from the top
27:32
to this point is of 8 mm and now let's see what is
27:40
unconstrained so here if you see this line so it should be also symmetric with the
27:49
axis so let's click on the symmetricity constraint select this point this point
27:56
and the axis and now select this line and this line and made it equal and now
28:04
select this point this line and this line and made it equal so our
28:09
uh sketch is fully constrained
28:15
now we will create a cut so let's switch to the flat lines view it is not working
28:21
so first switch to the shaded and then switch to the flat lines so here is our
28:28
sketch we can also validate our sketch so we can select it and click on the
28:33
validate options click on highlight troubleshoot work sets so nothing is highlighting after
28:41
clicking on uh highlight troublesome works so our sketch is
28:47
fine it is a common practice you must follow for the every sketch select the sketch and uh click on
28:55
the cut and here we can say through all or we can define end condition up to
29:02
face say okay now let's uh move to the next
29:08
feature next feature is to provide the fillet if you see here in a front view
29:15
the R six fillet is given which means that all four fillet at the bottom and all four fillet at the top are having
29:23
the same R six but the problem is that if you provide the exact 6 mm fread
29:28
fillet will fail so press zero and click on the fillet and uh let's first select
29:36
the edges now select this edge on both the
29:45
side if you are facing a problem in a selection then simply zoom it for easier
29:51
selections same way on the bottom side select this edge and this edge so here by mistake
30:00
face is selected so we will simply remove it do not cancel this we can easily remove it if any unwanted is got
30:09
selected now select this edge and let's select the bottom two
30:18
edges so everything is selected so instead of 6 mm we will provide 5.99
30:28
so you can see that a fillet is created and now let's move to the next
30:35
feature so if you see the isometric view there is a drill
30:40
hole of 15 mm so we will uh simply
30:45
select the face and uh click on the sketch option and here let's rotate our
30:54
model and uh click on the circle tool and create a circle select a smart
31:01
dimensions and provide a 15 mm click on close select the sketch
31:08
click on the cut and from here say it through wall and say
31:17
okay now let's uh move to the drawing and also place our model to the
31:24
isometric view now you can see that uh we have
31:29
successfully modeled this part and our freet model is matching with our
31:35
reference isometric view so we have learned how to model this
31:41
part with the help of a part design workbench and we have learned how to add a relations between the dimensions we
31:50
have learned the mirror we have learned the fillets basic tools of a free CAD
31:55
modeling with the part design workbench so this is all about this tutorial thank you for watching and uh thank you for
32:03
your valuable time
