Hello friends welcome to FreeCAD tutorial and in this tutorial we will
0:04
model this impeller in FreeCAD and we will model this with the help of a
0:10
part workbench and I will show you from the scratch how you can do the same in
0:16
FreeCAD you can also visit my website macnexus.com where I write articles and
0:22
tutorials on FreeCAD you can also download my tutorial source frame from
0:27
the here you can also support my work by buying my free cad crash course for
0:34
beginner it is a very basic level course for the beginner user where a beginner
0:40
user can master the free cad and you can also support my work on coffee.com you
0:47
can buy me a cup of coffee you will get my website link and my Ko-Fi donation
0:53
page link in a video description so I will close this file and I will create a new file
1:05
so we are going to made with a part workbench so these are the tool which we are going to use
1:13
inside the part workbench so first we will switch to the sketcher and create our sketch
1:19
so here on plane option we will select this xy plane and we will create our
1:27
sketch so first we will create a rectangle like this and then we will give
1:41
the dimensions so for example this point and this point I will give the horizontal
1:47
constraint and from this point to this point it is 15 mm I will move this
1:58
dimension outside and I will select horizontal dimension and I will give this
2:06
ET and vertical dimension will be 5 so our sketch is fully constrained we will
2:20
close it switch to the isometric view and now we will create one more sketch by
2:33
copying the existing sketch so we will select on copy and then we will go to
2:40
the edit and then click on the paste so you can see that we have the two sketch
2:47
overlapping to the each other now click on the second sketch and on here
2:56
property of the sketch go to the placement and we will rotate this sketch
3:09
so we are going to give angle 30 angle 30 and position under the position we
3:22
will give the Z 24 so you can see that our sketch is rotated by the 30 degree
3:34
and if we see our sketch from the front plane and it is moved to the 24 mm now
3:45
we will switch to the isometric and axis option will be remain X 0 Y 0 and Z 1 so
3:57
this is the angle 30 Z 1 and Z 24 now we will move to the our next step next step
4:09
is we will select the sketch 001 go to the edit and copy and then edit and then paste
4:21
so you can see that sketch 001 and 002 are the overlapping to the each other and now we
4:28
we will switch to the click on the sketch 002 and angle we will provide here the 50 degree
4:43
position will be the 40 mm 40 and axis will be the z1 now if you see from the top so we are seeing our
5:06
profile like this so now if we see our sketch 001 so rotation angle is a 30 so
5:16
we will make it 25 so that it looks good and the distance Z is 24 and we will make it 20 and now for sketch 2 distance is 40 and angle is 15
5:38
So here we have the 3 profile which is made with first profile and rest of the two sketches
5:46
we have made with a copy, rotation and distance. let's move to our next step our next step is that we will switch to the part workbench and we will
6:00
use the loft tool so here we will click on the loft so here we will select on first sketch click
6:09
on add click on the second sketch add and third sketch add and now here we have the three options
6:19
here create solid create rule surface or closed so we can create a loft surface
6:26
solid we have both the options so it is a impeller plate so we will click on
6:33
create solid and we will say ok so you can see that a loft has been created
6:41
with our tree profiles now we will switch to the next step and in the next
6:52
step we will use to the draft workbench polar array so I will select all this
6:59
sketch and press the spacebar we will hide it and now we will switch to the
7:05
draft workbench so now on here draft workbench you might see here the grid click on here to off it
7:21
now for polar LA select the loft and click here and click on polar array so here on the polar array
7:33
we are seeing the polar angle and number of elements so number of element will be
7:39
the 8 and now we will keep this X Y and Z 0 angle 360 and number of element 8
7:54
and press enter so you can see that our blade is got polar pattern and now we
8:05
will switch to the next step before going to the next step if you click on
8:10
this polar array so number of count you can increase or decrease from here polar
8:21
array option here if I make here the six and press enter so you can see that a
8:28
number of blade got reduced from 8 to 6 so we will keep the 8 now we will move
8:35
to our next step our next step is we will create a sketch with the help of a
8:43
sketcher so we will switch to the sketcher click on the sketch and click on
8:51
the exit plane and now here we will switch to the model tab and click on this
9:02
array and press the space bar to hide it now we will create our profile for this
9:11
I will use the polyline tool or line tool so I will select the line
9:41
So this is our profile and now we will constrain it
9:56
First we will constrain this line. So I will select this point and this point and give the horizontal dimension of 10 mm
10:09
this point to this point I will give the vertical dimension of 10 mm and I will
10:17
move it to the outside and this dimension I will give the 10 mm and I
10:27
will select this and I will give the vertical dimension of 55 I will move to
10:35
the outside and now I will move this line little bit outside this line I will take inside and this is the 71 71 and
11:09
and this line dimension I will move to the top side now I will give this line
11:15
dimension 9 mm and this will be 15 I will switch to the isometric and then
11:31
front this is 15 I will move the dimension outside so that it will be
11:47
clearly visible and this line would be this vertical line would be 5 mm so here
12:02
is our sketch is complete you can see the all the dimension clearly now we will
12:11
come out of the sketch switch to the isometric and now we have the blade if we
12:23
on our model here so we will give fillet So we will give the fillet here so for this we again off it and go to the sketch and we
12:46
will click on the fillet option. Fillet select this line and this line and now we will give fillet of 35 mm so we will
12:58
select radius and I will give it 35 and now we will revolve it I will close it
13:10
and again switch to the part workbench and we will use the revolve tool which
13:20
you can see here click on it so here our last sketch was sketch 003 we will
13:30
keep X 0 Y 0 Z 0 everything 0 and from here we will click tick mark on a create
13:38
solid and we will click on the ok so you can see that a revolve feature has been
13:44
created and now we on our blade so you can see that blade is interfering with
13:52
our revolve features so now here we will use the boolean operations so here we
14:04
have the two bodies so we will use the boolean operations to combine these two
14:11
bodies to make it one complete solid for this I will select the array and revolve
14:20
and from here you can see the option of a union so click on it so it is a
14:29
combining the two features now we have the fusion one is a final body so this
14:37
is how to model the impeller now we will render our this impeller blade using the cadres in my
14:47
previous video i have already explained how to install the cadres using the website opencascade.com
14:57
so here i have a open the cadres all you have to do is visit the google and search for the
15:06
cadres download and you will get a zip file and run it so here is a cadres is a
15:17
launch now I will select my body and go with the export option and save my file
15:25
as a step file and I open the cadres I will go to the file sections and then
15:34
click on import and I will import my blade so here I will select my blade and
15:46
go on the material tab and give the material chrome
15:56
and now you can see that our impeller blade is rendered you can tweak the
16:08
settings to get the better rendering image and after the rendering as per
16:15
your choice you can adjust the light colors and camera and you can go to the file section click on the save image so that your rendered body will be saved as a image this is how we have learned model of impeller blade in
16:37
a free CAD and render it using the cadres so this is all about this tutorial I
