hello friends welcome to free cat tutorial and in this tutorial we will
0:05
learn the revolve tool under the part design workbench revolve tool is
0:10
basically used to create a circular object it may be shaft or flange or
0:16
anything else which is circular in a shape you can also visit my website
0:24
macnexus.com where I write articles and tutorials on FreeCAD you can download my tutorial source file
0:33
from the here if you like my method of teaching then please support me on coffee.com you can buy
0:42
me a cup of coffee your small support will help these channels to grow and it will motivate me to
0:49
create more awesome content on free cat I will provide my website and my Ko-Fi
0:56
donation page link in a video description so let's come back to our tutorial so if
1:04
we see the this image here a is a profile b is a axis and this profile
1:14
revolved with respect to axis and here is a circular object created so we will
1:22
see the what are the others options in a revolve tool if you have used the any
1:30
other CAD software like SolidWorks Autodesk Inventor CATIA UG or Solid Edge
1:37
then you may have a go through this revolve tool this tools having the different name in a different software here in free cat it known as a revolutions so for this we will understand how to use
1:58
it under the various options available so first I will create a body and I have
2:09
activated the part design workbench now I will on my origin plane and here we
2:21
have the three planes so we will create sketch on any of the plane but I will
2:27
select this yz plane and create a sketch and I will go to the model tab press the
2:33
space bar and off my origin plane now here I will select the polyline tool and
2:42
create a rough profile and now I will give the dimensions so before giving the dimensions I will
3:03
select a line tool and I will draw a horizontal line and I will make it a
3:09
construction I will select it and I will make it a coincident relation and now I
3:17
will give the dimensions I will select this one and do some approximate dimension
3:25
let say I give 10 mm and now I will give the total length I will select it and give
3:37
the horizontal let's see I give it 60 and from origin point to this point
3:46
vertical one give the 15 and now I will select this top points and origin points
4:00
and give the dimension of let's say 45 now I will give this horizontal dimension
4:09
of 10 mm so our sketch is fully constrained I will switch to the isometric
4:19
view now I will close my sketch now we will select our sketch and click on the
4:32
Revolve tool so here FreeCAD automatically took this Z axis if you see with respect to our UCS
4:42
so when we Revolve FreeCAD automatically took some axis but here we can select our own axis
4:52
for example here we have the construction line which we have created in our sketch
4:59
if you select it then you can see that the shape has been changed apart from that you can select
5:07
any axis like x y or z so if it is revolve is not possible with respect to x so it will not be revolved but if I select the z it has been selected and we have one more options which is known as
5:28
select reference if you click on the select reference then you can click on your own reference
5:36
so here possibilities is that this part may be revolved with respect to z-axis or with respect
5:41
to y axis so here I can select my own axis so we have a multiple options here
5:49
available now if we go here we have the angle options this is a 360 degree
5:57
revolve but I want it half so I can give the angle 180 so you can see that it has
6:06
been revolved 180 degree now if I keep the symmetric to the plane then it will
6:13
consider this z or y-axis plane and it will make it a symmetric if I uncheck it
6:22
then it will be unsymmetric and we can change the angle as per our requirement
6:28
either we want half quarter or full so this is how you can use the revolve tool
6:38
in free CAD so now I will keep it 360 degree and always check on this update
6:47
view and click on ok so this is the very small tutorial how to use the revolve tool
6:54
in free cat I hope you have liked this tutorial thank you for watching and thank
7:00
you for your valuable time
