All language subtitles for 613241-22 - Eraser - The definitive SKETCHUP course. From beginner to expert.en-US

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.
