Hello people and welcome to this new class in

where we're going to see the saddles trip.

It is already expanded and we have as well

a toolbar called Show Hide settles.

Here.

We have the main options,

but if we move to the tray shadows,

as you can see, we'll find here many more options.

So let's start from the beginning.

We have this button, so hide shadows.

It is the same as this one.

So if I hit,

then I am switching on the sun.

In a sketch, we have now

these cast shadows on

the ground and thanks to these, sliders,

will be able to adjust

time and the day and a specific day,

which will change the position of the sun

and then it will make change as well, the cast shadows.

So e.g. if my time is 12:00,

I mean, it is known and we change the month,

moving the slider to our summer months,

not a winter month,

the cast shadows will be very short

as it happens in our normal life.

On the contrary, if we are still using the same time,

12:00, but our month is, let's say e.g.

November, the cast shadows

will be much more longer, right?

We have to control these settings in

order to make the best of our project.

Anyways, we have here more oxygens.

It is the light.

Now we're not talking about the cast shadows.

We are talking about the light.

So we can make that light lighter here, e.g.

or we can make that light more bright.

The next slider is talking about this time,

years, about the cast shadows.

We can make them lighter or darker.

This another option called use sun for

saving makes sense if this button,

the first one, so hide Santos is turned off.

So let's do it.

We don't have cached silos anymore,

but we are still using the SketchUp some

because this oxygen is already marked, right?

That means that we have some faces

illuminated while others are not, right.

E.g. this one, the difference is that

we are not using cast shadows,

but we are still using the position of the SketchUp son.

If I unclick this option we have is still

an artificial light because some faces are eliminated,

but not all of them with the same intensity.

But right now, as we are not using this upsilon,

that artificial light has nothing to do

with the SketchUp sun and then with this slider.

So this option, in my opinion,

it is not very useful and important.

Anyways, we can mark it.

Let's turn on so high shadows.

Let's check these other options on faces,

on ground from edges.

To understand better this option,

I will draw here a cylinder.

Then we will see how we have cast

shadows on the faces of this cylinder.

If I turn off on faces,

then you can see how

our cast shadows is not

affecting the phases of the ceiling.

So to be more realistic,

I recommend you to use this option on faces on ground,

as you can imagine already,

is going to allow us to cast shadows on the ground.

If I turn off this option,

we don't have Saddles anymore on the ground,

but pay attention here because it can seem

obvious that we will need to use

all the time this on ground epsilon,

but it will depend on its case, e.g.

if I have this kind of situation

in where I have a hole like this one,

Let's draw it and then I turn on,

on ground, I will move.

Don't read the data slider.

And the time, you can see that here we can

find a kind of error, right?

Because this cast shadow from

the queue on the ground is turned on,

is going through the whole plane as a horizontal plane,

and it is not going inside the hole,

is not working in a realistic way, right?

So how we can resolve this problem?

First of all, we have to turn off on ground,

then we have lost the cast shadows on the ground.

Obviously, in that case,

we will need to create our own ground.

So I will select this x

and I will make this phase much more bigger.

I will reverse phases.

And then if I move the sliders,

now, I don't have that problem, right?

My cast shadows are working in a normal way.

We're not creating that horizontal plane.

I will turn on,

again on ground as it happens here, right?

So on round is not

always an option that we have to mark here, e.g.

it is better to create

our own ground and unclick this option.

Finally from this will allow us

to make cast shadows from an egg.

Individual ads, e.g. I.

Will draw here a vertical.

Now this is not making any shadows,

but if I click from edges,

you can see that now we have this x.

Let's jump now to these projects.

A Greek temple, and let's use the subtle Stray here.

First of all, we have to turn on the shadows.

Here they are.

And now through these sliders,

we will control the position of our cast shadows.

E.g. here could be okay.

We will use this example for

explaining another important tool.

When we are working in a project like that,

maybe we want some elements to have

an specific behavior in

terms of cellulose, e.g. the roof.

Sometimes maybe we don't want to

cast shadows or to receive shadows.

If we want one element to behave in a specific manner,

we have to select it,

go over Entity Info,

and then we have these two options.

One is called Dawn receive shadows,

and the other one is called Don't cast shadows.

So e.g. this roof,

it is already selected.

If I hit, don't receive shadows,

it will not change now because we don't

have any cast shadows on it.

We have just the light of the sun.

But if we hit,

Don't cast shadows, then it will change a lot.

What is happening inside

the building because this element,

this roof, is not casting shadows anymore.

We could do the same with this.

Another roof don't cast shadows and then create

inside the building another effect

with more and more light.

Of course we are,

Let's say that we are cheating a little bit or a lot.

But sometimes could be very useful in

order to put some more light inside

our interior and being able to tell

our client or whoever

our ideas in a better way in a sketch.

My last advice here is that you have to be

aware that when we are using the saddles in SketchUp,

we're consuming a lot of resources of our computer.

So just turn them on when you really need it.

The rest of the time when you are working,

just modelling, my advice is to turn those off.

So we finished the episode here,

and I will see you in the next

one in where we will continue

modelling our Barcelona Pavilion using our new skills.
