Hello people and welcome to

this new class in where we are going to

learn how to use the rotate tool in a sketch.

So these Rotate tool,

it is here in the transformation panel.

And thanks to this tool,

we will be able to rotate in

a very precise way and we will

even be able to rotate and copy.

During this class, we will use

this chest bone that we drew you in a previous exercise.

So I'll ask you to open it.

Once we have it here,

we can check that this chest bone is what we

call free geometry because we can touch the geometry.

It is not inside a group.

We could place this geometry inside the group or not,

doesn't matter for using these Rotate tool.

The thing that we have to do is select

the elements that we want to

rotate as far as this geometry,

not inside the group,

I will make a selection box,

then Rotate tool and

a protractor will pop up in the screen.

The color of that protractor is the key for the rotation.

Now the color is blue,

which means that we are working in

the plane perpendicular to the blue axis.

The rotation will occur in that plane,

but we can change that plane just by

clicking and holding down the left button of our mouth.

So let's choose that first point

which is paramount for the rotation.

It is paramount because that first click will be

a point that will work as an anchor of the rotation.

So that first point should be placed

on any point of that baseline, right?

Let's say e.g. here in these midpoints.

So click and hold down,

and I move around my mouth.

As you can see, the colors of the protractor are

changing and then I have to choose the correct one.

This time, I want the red color,

which means that we are working in

the plane perpendicular to the red axis.

Once the red color is on my protractor,

I released the left button of my mouse and that color,

that protractor, that plane is already fixed.

Now it gets app is asking me for that second point.

We already fixed first point.

And with this second point,

what we're gonna do is to create an axis,

an axis for the rotation.

So it's not that important if that point is

here or here because we are creating kind of an axis.

Let's say here, second point, click and release.

And I move. Now is the time for the angle.

We can precise that angle graphically

just by moving the mouse and clicking for the third time,

or typing in that angle in

the measurements bar e.g. Nike.

And here we are basically on one click outside,

the rotation is finished.

Let's repeat it again.

This time I will make a group right button.

Now the chest bone is inside the box.

Rotate, I select the first point,

the one which is going to work as an anchor, e.g.

here, click and hold down,

I select the color of my protractor.

This time it should be blue. Here we are.

I released now, I need to assign

the second point for creating that new axis.

Second click, e.g.

here, I move my mouse around,

time for the angle, let's say 90 degrees this time,

I will do it graphically.

Third, click on the rotation is finished.

As you can see, we will need three clicks.

First one, click and hold down,

then click and release for creating an axis.

Then thirdly, four, assign

the correct angle based on my experience,

if it is the first time that you are using this tool,

it can be a little bit tricky,

but I can assure you that you will get it.

Let's go now with

another option of these to rotate and copy.

I will move first of all,

this geometry to the region.

Then I will move it along the red axis and imagine that

now I want to rotate that just bone around.

But in addition to rotate the figure,

I want to make some copies. How can I do that?

Well, first of all,

I have to select

my geometry one-click because it is a group.

Then again, rotate tool and the first point,

remember that it has to be like the anchor point.

The anchor point this time will

be placed on the origin and

then time for fixing

the planning where the rotation is going to happen.

Blue color is correct.

So I released now till here,

everything is the same as before.

Now second point for fixing the new axis of rotation,

let's say any point of the red axis.

Then I move the mouse time for the new angle on here.

At this very moment is when we have to tap Control key.

If I tap Control key,

you can see that we have created

a copy exactly the same way as

when we were using

the Move tool and we wanted to create a copy,

we fixed that new angle,

let's say 45 degrees enter and we

have that copy and that rotation already done.

The copy is still selected.

So as we did with the Move tool, now,

we could tap arteries and say how many copies we

want using that angle of rotation.

Let's say e.g. for Arthur is four.

And we will create four copies instead of

1,123.4 as we did when we

were using the Copy tool here with the rotate tool,

we can use the asterisk for copying thing or

that inclined bar above number seven control set.

I select my chest palms, rotate,

anchor point, click and hold down.

I select the correct color.

I really second point for

fixing the new axis of the rotation.

I move the mouse around,

I tap Control key for making a copy,

third fleet for fixing the position of that copy.

And this time still when that copy is selected,

inclined bar and number of copies that I

want to have between the original geometry.

First copy, Let's say e.g.

six Enter here we have 123456 copies,

seven in total with the original one.

So as you can see,

we can be super precise using the rotate tool.

So time to say goodbye now,

and in the next class we will go through the scale tool.
