In the challenge or the practice activity we agreed that we are going to create a complex shape like
this and rotate rotated in a certain way.
You know one is rotating the other direction one is rotating the opposite direction of the other fine.
So how will we create that.
Let's not just shootings.
First of all we notice that we have the gears here or the protrusion we have 12 of them and at the start
we have five corners on three or five spikes and we have a certain dimension he has certain thickness
for the good fun that's all I can notice here.
The most important for me is the 12 and how that cutoff.
You notice how they are cut off pretty heavily here.
Fine.
So we have a new composition here which is completely empty.
Let's start by adding For example our start to click anywhere or in the middle and open so I'm getting
a very funny side.
That's pretty good.
That's not important.
First of all what you want is to come over to the point and make them 12.
That's one.
Then I want the inner radius to be bigger than this.
Fine so you know this now if I can over here what will happen.
So you want to know exactly how much of the spikes you are making bigger then the outer radius.
Let's make them a bit bigger.
OK that will work.
We don't mind if it comes out of the composition because we are going to trim it of course.
So let's go to the transform here and put the position at 0 and another zero here.
So it's quite in the middle.
Fine.
This is done.
What do I have.
I have a content inside it there is a polystyrene so I will come to the police side inside the police
start here and I add in elipse that's it.
So I have my lips here which I cannot see at all.
So let's see if we move it make it bigger and bigger.
Oh that's OK.
It's fine.
And we want to get it somewhere.
But I can see how fine.
So while I do I will select stroke and add a most part.
So this most pass comes above the stroke.
Now this while we want maybe to use substract is not working let's use intersect while intersect is
working.
You really want to try you really want to understand how these things are working.
You don't have to have the solution.
You want to understand how to do it now very fast.
Now also I need to carry it over here.
If you remember so it seems to me that the spikes are not very.
They need to be bigger.
So I will increase the outer radius is not working so I will increase the radius.
Yes that is working fine.
That's OK I think.
OK.
Now we had our star we have our most path and we want to add another piece.
I will add another elipse that will be the trimming elipse now not is that it's game above the past.
That's not good for me I'm going to put it under.
I can see my lips and see it make it bigger.
Let's stop it over here.
OK that looks good.
And then what I need is another most bath I will come to stroke to put the most part above the stroke
just under the lips too.
And here we are we add another path.
It's not happening.
Put it under.
Could I guess this one will leave it to.
Or we can use merge to make it one single one.
I would leave it to.
That will be OK.
Then I need to add the other lips.
Another eclipse here I will add another eclipse.
I will take it under the most path that my lips has 100 by 100 make it bigger.
So I want the borders.
It will be over here.
I will now in numerous path and that's going to be maybe a obstruct.
We'll see how it's going to happen.
We opened the third pass and we say subsect or here to.
You know this will happened that the Mersch passed to here made them all one.
Right.
It became one element and the substracted is substracting least three from the Halmos path and now we
have a small problem here.
The lips is a bit small so we're going to make it or it's big.
We are going to make it bigger so we don't see this Poynting outside.
Good.
So everything is fine now.
Now what I want to create is the inner wheels or the police style that will be a star.
OK.
And it has only five sites.
So I will create it within the same shape there.
Of course.
I'll click on the star come in the middle click hold shift and make it bigger OK it has five sides that's
OK with me.
Make it touch a bit.
And now it's on top here.
That's not good.
We are going to put it under you.
So now you have two major groups here.
I will come to the Pollstar.
I will open the police start here and make the register in a radius bigger.
That's cool fine.
And actually it's very good.
Now also what I want to do is to add after the pollen inside the police here.
I want to add an ellipse.
I would click on ellipse.
I make sure their lips is under police stuff too.
And of course on to the Mersch path.
And this time I'm very sure it's going to be subcircuit.
Oh cool.
It happened.
Then I'll go to elipse wireline and make it bigger as much as I need.
That's very nice.
So it's working.
It's perfect.
So I can name this one group one for example or out of here and this one and group two that I can do
that I could have also created these groups.
I moved everything inside.
So the feel here I will change the feel to read or actually is the outer one that is red.
So Group Two is red.
So I would come to the field and change it to read something like this cool.
So I have it all working now I need to animate it which is pretty simple here.
If you're not very well I work differently from the other one when you can download the file you will
notice that I work quite differently but still I have some good results so I need to animate so outcome
to group 1 and I have the transfer and only the stroke I'm going to deleted and transform here.
I have rotation out keyframe the rotation go to three seconds that's good enough.
I make it one.
So now the outer one is rotating the inner one is not rotating yet I will come to group two of course
I will do the stroke I like it here I will go to transform group 2 and keyframe it a three second and
right minus one come back to the beginning and give it the zero area.
Let's turn our animation and see what's happening.
Cool.
That is fantastic.
It stops.
So what you are going to do is to come to the player press you.
We have all keyframes misplaced.
I will take this one and put it here.
Take the first keyframes.
Select them and copy them using Control C and go to the and we press and to go to the end and we make
control V.
Let's see what's happening now we go back to the beginning and our rotation.
I think it's working very fine.
You'll notice how the copy happened.
I just looked at the previous one and tried my best to make it as it is.
Now the great experience that you have here when you will download the file is that the gear challenge
the way I've done it here is different from the one I have done just now.
You've not just now the feel are inside the groups and not outside the group.
This is because firstly I created the police and outside the poly star I created the path.
The other one and the path what I have done here is in the group 1 I created the Pollstar and inside
the police started this was said if you remember I created the that path.
So it's a bit different but yet I'm having the same result and I'm sure if you did that exist size you
would also have the same results with different method.
This is to show you that there are similar ways to do certain things at certain complex shapes and yet
we get the same results.
Thanks very much for listening.
I will see you in the next lecture or in the next section.
