hello friends welcome to free CAD tutorial and in this tutorial we will
0:04
learn extrude feature of a free CAD so here I have launched my free CAD and I
0:10
will create a new file you can also visit my website macnexus.com where I
0:17
write articles and tutorials on free CAD you can download my tutorial source
0:24
file from the here if you like my method of teaching then please support me on
0:30
coffee.com you can buy me a cup of coffee your small support will help these
0:37
channels to grow and it will motivate me to create more awesome content on
0:42
free cat I will provide my website and my coffee donation page link in a video
0:49
descriptions so let's come back to our tutorial and before starting let's
0:57
understand the concept of body and this part so body is a anything which we made
1:08
in a free cat and part is work as a container for example I create a body
1:16
here I create one more body and now if I click on the part then part get inserted
1:25
in my browser and now I can simply drag my body inside the part so you can see
1:37
that this part is work as a container so it is your choice you use this part or not but it is recommended from my end it is very useful to store the multiple bodies so first insert a part and then create a body now let create
2:05
a new file and to understand the extrude features I will simply select a body and
2:12
now you can see that nothing is visible on our user interface so click on origin
2:25
and press the spacebar so that datum planes and datum axis will be visible now
2:33
here you will have the options to select the plane I would prefer the front plane
2:39
I will select it and click on the sketch now go to the model tab and press the
2:47
spacebar to hide the datum plane and axis now to understand the extrude
2:55
features I will simply create a rectangle and I will make it symmetric so I will
3:04
select the symmetricity constraint select this point this point and origin point now our rectangle is symmetric now I will select the line select on
3:18
horizontal dimensions give the 200 dimensions I will select the vertical line and give the vertical dimension of 100 say ok so our sketch is fully
3:30
constraint and it turns into the green now I will go to the task tab and here I
3:38
can see the constraint and here I can see the entities of my sketch now I will close it now I will click on the pad so once I
3:52
click on the pad you can see that the pad length so that here I can you my
3:58
length let's I give it 60 so you can see that it is extruding in one direction
4:05
only I can make it symmetric so click on symmetric to the plane and now go to the
4:13
model and on the origin plane so you will see that now our extrusion is
4:19
symmetric and if I uncheck it then my extrusion will be in one directions and
4:28
now I will say ok now here we will understand what is up to face and two
4:41
dimensions so two dimension is used when you want to give the unsymmetric length
4:49
length for example in one directions I want 100 and in other direction I want
4:57
500 so you can see that this is the unsymmetric extrusion now let's
5:05
understand what is up to phase so for this we will go with dimension and make
5:12
it symmetric to the plane of a hundred mm and say ok now to understand the up to face extrusion
5:22
I will on my origin plane and I will select my front plane and click on the datum plane so here
5:31
on direction in Z directions I will give the 250 distance so you can see that a datum plane is created and I will say ok off my origin place by pressing the spacebar now you can see here blue tick
5:50
symbol it is a for the rebuild so click on refresh icon or press the f5 from
5:57
your keyboard now I will create a sketch on my datum plane so select the datum
6:04
plane and click on the sketch and now here I will create a circle and select
6:15
the circle and give the diameter dimensions let's see I give it 80 and I
6:22
close it now I will off my datum plane now I will select my circle and click on
6:32
the pad so you will see that you are not seeing anything on a screen for this
6:39
click on the reverse and from here click on up to face so here the face I will
6:49
give this face so you can see that this extrusion go up to the disk face here
6:58
you can see that selected face is a pad f6 so if I wanted to change my face then
7:07
I can also select my back face so extrusion goes up to the that back face
7:17
now this is the very basic introduction about the extrude features so this is
7:27
all about this tutorial extrude feature in free cat thank you for watching
