Hello everyone and welcome to this new episode

in where we're going to talk about the arcs.

We have four tools for the arcs.

The most important ones without any doubt,

or the first two,

this one and this one.

And in my opinion,

this second one is even more important.

So I will leave this tool for the end of the class.

Let's start then with the arc from

center and two points. One-click here.

Then it appears that protractor, in my case,

with the blue color due to

the position of my camera here,

pay attention because if we normally click and release,

we have the protractor on the screen.

It means that we have the possibility about

changing that color by clicking and dragging.

So if I click here and I drag,

I am keeping hold down the left button of my mouse.

Then I will be able to change

the color of that protractor.

And by doing this,

I am choosing where I want to draw that arc.

Let's say here in the red one,

then I have to release the plane

and the center of the arc is already 2AM.

And then SketchUp is asking me

the length of that arc from the center.

And of course, I can type in

that length in the measurements bar.

And I can choose as well, the direction.

Let's put it on the ground floor and

I will type in 3 m length,

enter the second point of

the art is already chosen as well.

It Mrs. just the third one.

And as long as I'm moving the mouse,

we can see it already on the screen, right?

Let's do a quarter cycle or we can even type in

again the angle measurements by third click and release.

And here we have our arc

drawn on the plane perpendicular to the red axis.

And with all of the specifications

we have been deciding

together during the drawing process.

If I go closer to the arc,

we will see that as it happened with the right call,

this arc is Sharpie made by different actors.

So it doesn't give us the feeling of a curve.

The reason of this is because when we choose

the tool first option that we can

change is the number of sides.

By default, we have 12 sites

for the arcs and that is at all,

we were to change that number to at least 24.

The double I alluded to before Enter.

Then I will repeat the same operation.

Click and drag, read protractor,

I released second point,

third point, creating a quarter cycle.

Here we are.

And now this arc is much more smooth.

If we want more sites, of course,

we can do it depending always

on the level of our drawing.

Let's jump now into this next tool, Pi,

which is exactly the same as this previous one,

but the tool will generate a surface.

Once we have finished our arc,

I will show you, I will repeat the same arc.

Click and hold read.

Protractor released on the green axis, 3 m length.

I move my mouse quarter cycle.

Third click here we are our arc.

But at the same time,

this tool generated the surface

because we have of course,

those two lines for closing

the surface and create this way,

this kind of quarter.

Alright, nice.

Let's jump now to this next option, three-point arc.

To be honest, I have barely

use this tool in my work experience,

but I have to show you.

So thanks to this tool,

you will be able to draw an arc through three points,

which all of them are part of the same circumference.

Click and release. Click and release.

We have two.

Then the circumference pops up and we have

just to click again for the third time.

In this example, again,

we find our arc very sharp P.

So we could go back to the tool,

check the number of sites that we are using.

Once we have changed That number of sites,

the file will remember,

and we will not have to do it again

just in case that we open a new file.

In that case, yes.

Let's go finally over these main Arc tool to point arc.

One-click.

I will move here till this side and I will draw

my first arcs on the ground floor, one single click.

I will hold myself on the green axis.

Second click, and then I move my mouse and I

can choose to draw along the red axis.

Or if I move the mouse along the blue one.

Besides, I can type in the lens or do it graphically.

Let's do it graphically this time.

So third click, and here we are easy to draw.

But the most important thing here is that we can keep

drawing Arts in a continuous way and then create a more,

let's say, sophisticated curve.

Let's do it again.

But this time, fixing the number of sides of

our arc space key for going to the selection tool.

Then I go back to these specific two-point Arc tool.

I can check that the number of sides is 12th.

Let's say 24.

Enter one first, single click,

second single click, third, single click.

Now let's continue the curve.

First.

Single click on the nth point.

And then when I move my mouse around,

you will see that the color of the arc now is

the meaning of this is that that arc

is tangent to the previous curve,

to the previous arc.

Tangent here is a very,

very important word because

if you know a little bit about the geometry,

when we have two curves,

tangent between each other

means that the curve is continuous.

So we read to have a complex curve, not a polygon.

Now, just 1 s. Click e.g.

here, and look what is going on here.

The second click was correct.

But then the tool is asking me

again for the length of this high.

If I want that arc to be tangent to the previous one,

then I have to look for that cyan color.

Click again.

Here we are.

Actually I can do it easily if I click twice.

In my second click, when I am here,

I will show you control set for going one step back,

then first click, second click.

And if I don't move,

either need to be fast.

But as soon as I move the mouse,

then I lose my color and I have to find it again.

But if I don't move it,

second click, click here,

we are a perfect curve.

To finish this class,

we will practice this tool,

but this time inside our rectangle.

Because here I will show you

another thing to point arc tool.

Then my first click here at any point along the line.

And look what is going on.

Again, the CRM color,

which means that this arc,

this curve is tangent to the x.

What ads?

The ads immediately behind the arc?

This case, this EDS,

I am pointing out,

the arc is automatically done

the end that S. And furthermore,

if I move the mouse still this next Ed's,

then I can find this another color, this magenta color.

The meaning of this curve is that the arc,

the curve is tangent to both edges.

The one behind the arc and the one in front of the arc.

Of course, if I move my mouse,

I can easily lose that color.

So second click here.

And again, if I don't move

the mouse and I click for the third time,

the arc is already drawn tangent to both edges and

automatically SketchUp erased that left corner.

So let's repeat this same operation on this corner.

First single click.

Then we have our arc tangent to that.

Behind us.

We choose the second click,

always alone, this another EDS.

And then we move the mouse till we find

the imagined color once we are here, second click.

If we move the mouse here,

we lose the color,

but we can find it again

with a little effort. Here we are.

Once we have the color search click on,

the arc is already drawn.

This time this gets up,

didn't erase the left corner.

This is something that is SketchUp does randomly.

So don't, don't take it seriously.

And if we want to erase this corner,

we can do it by ourselves.

Just hit the selection tool and we can relate this easy.

So time to say bile.

We have already feelings

all the drawing tools placed here.

And in the next class,

we will see this toolbar called styles.

And thanks to it,

we will be able to have more control about

the aspect and the properties of our surfaces.
