Hello people and welcome to this new class in where

we're going to talk about a very important,

useful, handy earn, a little bit complex tool.

It is the eraser, it is here,

eraser and you can read

erase often or smooth entities in the model.

But actually, it can do even more things.

So it will allow us not just to erase.

Here, we have a list of things that this tool can do.

Erase, select, Hide, soft and smooth.

And a part of this,

it is related with a tray called soft edges.

So we will see all of these things.

I will make you think a little bit so be ready.

First of all, we can erase.

This is the main thing that

we will do with this tool, of course.

So let's practice with

this cube letter E for

heating the tool using the shortcut.

And then you will see that the tool has

a tiny circle near the rubber.

And actually that little circle is the one which matters.

With that little cycle.

We will erase things. Here.

The mechanism will be click

and drag, not click, unreleased.

I click drag.

And then when I go over

any edge and I said It's not surface,

ads will be illuminated or better said, selected.

And then when I release,

I have just erased that.

And pay attention here because the only thing that

we erased was this EDS.

But as we saw in another chapter when we

talked about lines and surfaces in SketchUp,

these EDS, this line is holding two surfaces,

the one on the right side and the one on the left side.

And I point out this because you have

to understand that this tool is going to delay it.

Just lines or edges, not surfaces.

I can click and drag over this surface,

e.g. and nothing happens.

But when I move the mouse over any ads,

then all of them have been selected.

And when I released, they are delighted.

And then the surfaces they were

holding our delighted to hear e.g.

now I have just these leftovers which are lines.

They are not holding any surfaces.

So if I click and drag and I really,

only that, it will be delighted.

Right?

Let's jump now into the next option.

Select.

This is a very interesting property of this tool,

which just few people know.

It can be super, super useful.

So if I tap letter T, again,

I hit the tool and then I

repeat the same process as before.

Click and drag.

I move the mouse over different edges.

They are selected.

And we know that if I release now,

they will be delighted.

But if instead of relief,

I tap the space key,

then I maintain the selection

and they haven't been the later, right?

So I have used the eraser for selecting these edges.

I can assure you that it is

a very handy way for selecting things.

Imagine e.g. that I have to do

it just by clicking and clicking,

using Shift and clicking and clicking.

I will always have to be super

precise because I have to click on the line,

not on the surface.

So in my opinion,

this way for selecting things is much more easier,

faster, and even relaxing.

I repeat, you just have to click and drag,

go over the idea is you want to

select and before release,

tap the space key,

time to jump into the next property.

Hi, with the eraser,

we will be able to hide entities in a SketchUp.

Actually hide is a tool that

we can use apart from the eraser,

it is, let's say independent.

We can find it if we go over edit, hide, and unhide.

First of all, we need to choose

what we want to hide, e.g.

let's say this entire 3D model.

So I make a selection box,

edit height if I want to unhide this element,

again, edit, in this case unhide.

And we can choose if we want to unhide

the last entity or all,

let's say e.g. last.

Doesn't matter.

And now let's do it using the eraser letter E.

And then I have to hold down Shift while

I click and drag over the edges I want to hide.

Because again, the eraser is about edges,

is not about surfaces.

So e.g. I.

Am hiding all of these ideas I released.

And then you can see

the 3D model with those edges hidden,

not all, just the ones I selected.

If I go over edit, unhide,

all they will appear again on the 3D model.

Furthermore, if I make R group here,

I select all the elements,

right button, make group.

If I feed the eraser again and I go over the element,

you will see that I am selecting not just one,

but the entire books.

So now it is up to me either if I

want to delete the entire books

or just hide it by holding

shift this time I decided to hide it.

So if I go to Edit unhide, it will appear.

Let's move now to the next option.

So often and smooth.

This time for soft ten and smooth,

we will have to hold down Control key.

Remember that you can check all of

this information on the files attached with a course.

In this case, you better go to the shortcuts episode.

You will find there this J peg here.

If you go through the eraser,

you will be able to check all of these shortcuts.

Control for soft and smooth sift,

for hiding, Sift plus control and soften and smooth.

What soft and smooth do in SketchUp?

What is the purpose of this tool?

Well, so often is super,

super similar or better said,

it is exactly the same as high,

we will be able to hide edges of our model.

But this time we can say that it is a kind

of property for the Ed's

while we were using hide for hiding different elements,

groups, components, even surfaces if we choose it before,

the software tool is

just an internal property of the SDS.

So if I select it and I go over Entity Info,

here, I will find information about this.

Ed's the texture, the tag,

the length, and two boxes, soft and smooth.

Because soft and smooth are properties of the LTS.

If I select a surface,

these properties will not be here

because the surface is something different.

So coming back to the ED,

if I click on the soft box,

this element will disappear.

And it is actually like it is hidden,

but actually it is not.

If I go to Edit and hide all,

it will not appear because we are

working now with a property of the Ed's.

The meaning is the same.

This property is hiding the edge, yes,

but they are both different categories.

So if I want to recover this Ed's, how can I do it?

Because now I can't select it again and

go over Entity Info and unclick that box.

So I should go over view hidden geometry.

If I show the hidden geometry,

then that will appear under this new aspect.

Now it is adult line.

You can find here

different hidden geometry in which this curve,

this arc is based on.

Anyway, what matters to us now is

that if we focus on these ads,

just on this, now,

I can select it again.

And once it is selected,

I can go over Entity Info and unclick the soft box.

Now it is not so often anymore.

So if I go again over view and I unclick,

hidden geometry is again here with us.

I think it is clear.

So let's jump into the next property of the edges.

Smooth.

I'll go over view hidden geometry.

Then I will select

these different vertical lines

in which this curve is based on.

Because in a SketchUp,

you better know that curves,

perfect curves don't exist.

They are all the time,

many different straight lines

altogether creating this way the filling of a curve.

And that is the key for understanding

the concept under this smooth tool.

Smooth tool is created by SketchUp

in order to render the different shapes.

In a way in where we can believe that we

are watching a curve and organic model,

not a 3D model,

based on different polygons.

So if I select this hidden geometry and I will do it

using the eraser as we have already learned, space key.

And then I check the entity Info.

We will see that these Haydn geometry

is soften and smooth.

Of course, it is because it is

an example of a curve in a sketchy.

But if I unclick a smooth

and I unclick hidden geometry as well.

We can appreciate perfectly the different straight planes

even when the edges are hidden or soft and better set.

But the problem now is that the edges

are soft but not a smooth.

If I wanted to smooth them,

I should go to View Hidden Geometry.

Select again this geometry,

and this time I will do it using the selection tool,

clicking and clicking again,

then go to entity Info and say a smooth, here we are.

I can unclick hidden geometry and now I have

this curve again rendered in a very smooth way.

Finally, to finish this episode,

I would like to just mention

this soft and add yes tray that we

can find here on the Default tray.

If you don't have it, then you should go

to Window Default tray.

Here you will find soften edges using these Default tray,

we will be able to soften and smooth

all the ideas of any object in a very rapid way.

Imagine e.g. this cylinder.

We already know that the heat and

the geometry is soft and smooth.

And if we wanted to do the same

with the rest of the entire model,

we should select it and then go into

stuffed and edges and play with this bar.

By playing with this bar,

it is like if we are clicking on

those both boxes so often and smooth,

sometimes we can find

some leftovers inward is not working the tool,

and then we better click on this soft anti-coplanar box.

Now my cylinder is completely soft and smooth.

But maybe you are wondering yourselves

why we have still this around.

And you should have the answer as well.

Because in the previous class,

we saw that in Sketch tab we have two different lines,

AD DS and profiles.

This line is like the term of the element.

It is the profile.

Here we are playing just with the head. Yes.

We should go to Styles, edit,

settings, and switch off profiles.

This is another reason for

not working with the profiles on.

If I go now over view hidden geometry and

I select any of the edges of this 3D model,

then I go to Entity Info.

You can be surprised if you don't find here those boxes,

those soft and smooth boxes.

And the reason is just because this entity is a cycle,

is not an ad.

It has actually 24 segments.

24. Yes.

Although it is soft and smooth,

it doesn't appear here on its properties.

We should explode the curve,

right button, explode curve,

and then we have here 24 edges

with those boxes already marked.

Anyways, the result is the same.

We have all these entities, soft and smooth.

This is something that we will use in

the future when we work mainly with the reins.

Time to say goodbye now.

And in the next episode,

we will start doing our first exercise in where we

will practice many of

the tools that we have been learning till now.
