Hello friends welcome to free CAD tutorial and in this tutorial we will do the free CAD
0:06
sketching exercise. So this is the very basic sketch and we will create this in free CAD
0:15
and we are not going to create a 3D model we will just create a 2D sketch and we will
0:21
learn the constraint and dimensioning in free CAD. So here for this tutorial I am using the
0:29
free CAD version 1.0 so you must have at least 1.0 or higher version of free CAD
0:37
you can also visit my website macnexus.com where I write articles and
0:43
tutorials on free CAD and you can also access my 3d part library of a free CAD
0:52
you can download the part from here and you can use in your projects with
0:59
modifications you can also access my 2d drawing library where you can download
1:07
this 2d drawings and you can create 3d models with respect to this drawings you
1:17
can also support me on coffee.com you can buy me a cup of coffee your small
1:25
support will help this channel to grow and it will motivate me to create more
1:31
awesome content on free cat you can find my Ko-Fi donation page link in a video
1:38
description as well as you can also see my Ko-Fi page URL on this header so let's
1:47
come back to our tutorial so first I will create a new file and I create a
1:54
body and we will select the front plane and we will switch to the model tab and
2:03
now let's create the sketching so before creating the sketching we will
2:09
understand the part if you see this sketch so we can find that this is the
2:17
important area so we will keep our part origin here so let's read the dimensions so here
2:26
we can see that we have a two diameter one is of a diameter 50 and other is of a diameter
2:33
100 so we will simply select a circle tool and create a two circle and first we will constrain the outer one select a smart dimension and provide the
2:54
100 mm and select the inner one provide the 50 mm now let's move it and now we
3:06
will create this bottom line so we can see that this is the 120 plus 25 so it is
3:16
145 so we will select a line tool and create one horizontal line and we will
3:25
fix its position and provide the vertical dimension so here to avoid any
3:35
confusion we can use the dimensional constraint as a calculator as well so 120 plus 25 you can add
3:47
and subtract value so it is 145 and now let's constrain this length so we can see the 96 plus
3:59
10 and 10 so we will select a smart dimension you 96 plus 10 plus 10 so it
4:09
is a 116 and now we will create these two vertical line so select a line tool
4:20
and create a two vertical line and let's constrain this with a 10 10 mm select a
4:31
smart dimension you the 10 mm move it and similarly on the other side select
4:43
this and this and provide the 10 mm now we will create one arc of R45 which
4:57
will be the tangent to this diameter 100 so we will select here create an arc by
5:06
three points so we will select our first point here second point on this arc and
5:12
and we will create a approximate one now let's first thing which we will do
5:19
is to constrain the radius provide the value 45 and let's drag this radius and select this and this and provide the tangential constraint and now select this line and this line and provide the tangential constraint here we have a
5:42
added 120 plus 25 which is the bottom one so here we will do one thing we will
5:51
select a line tool and draw a line and we will use the trim options
6:00
to trim this extra geometry and now we will select the two vertical line and
6:06
connect it select this and this now we will make it vertical and we will make it
6:21
vertical and now here we will again give the dimensions 10 mm and here also give
6:35
the dimension 10 mm and here 145 and this is of a 25 so let's also constrain
6:47
this vertical line with over 25 and let's move this 10 mm dimension and now
6:57
here is a radius 150 so we will create an arc the way we have created for r45
7:07
and we will make it tangent so simply go to the three point arc and select this
7:13
point this point and here first we will add a tangency and select this line and
7:23
this arc and add a tangency now if you see here this 10 mm dimension if you draw
7:34
a line so this is in a position with collinear so we will move it and we will
7:48
provide the vertical relation we can imagine from the drawing that this
7:56
construction line is a you know collinear with this 10 mm dimensions so
8:02
you can see that we have given the vertical relation and now if you see
8:10
here this point and this tangential point will be in a horizontal position select
8:16
this and this and apply the horizontal now let move the dimension and now let check this dimension R50 so let provide so sometimes if you select a smart
8:36
dimension it will not pick the correct dimension so in this case just press
8:42
escape and specific select the radius dimension so here is a 149 0 8 7 so we
8:54
will make this dimension reference so we want this dimension 150 so in this case
9:01
we will delete this horizontal dimension and we will uncheck this reference and
9:08
we will provide it 150 so so these and these are not a horizontal because this
9:19
is not given here because center is missing so as a drawing reader you have
9:26
to imagine some of the things while creating a technical drawings now let's
9:31
Let's move the dimensions so that you can clearly see it
9:40
Let's move this radius also and now let's move this and this
9:47
Now here we will go to the sketch and here let's hide all the constraints
9:54
So you can see that we have a successfully created 2D sketch with respect to our drawing
10:04
So this is the very simple exercise to understand the sketching in a free cat
10:12
And now if you want to on the dimension just press this eye so the dimension will be on
10:19
now we will come out of the sketch and let's switch to the isometric view
10:28
or we can switch to the front view so you can see that
10:32
it is exactly matching with our reference drawing so this is all about this tutorial how to create 2d sketch and the best part is
10:42
that you can select this sketch and export it to the dxf format you can select here dxf format and you can use other 2d editing tools
10:57
like autocad so you can see that our part is a fully matching with our 2d drawing so this is all
11:07
