All language subtitles for 613241-16 - Reverse faces - The definitive SKETCHUP course. From beginner to expert.en-US

Hello everybody and welcome to

this new episode in where
we are going to talk

about another concept which
is called Reverse Faces.

Well, when you are
drawing in SketchUp,

you will see many times
that your faces are colored

either in white or this
kind of gray or blue color.

This is because, as
you already know,

SketchUp is facing modeller,

not as solid Modeller.

So it is treating each
phase individually.

And we can say that its
phase has two sides,

the front side, the backside,

by default, the
front side is white,

this one, and the backside is
this kind of gray or blue.

If I select any phase and
I go to Entity Info tray,

you will see here
those thumbnails

representing those two sites.

The first one for the front side

and the second one
for the backside.

Right now, they are both the

same because it is selected
this default style.

But if I apply any color,

I go to materials, select.

I go here and I say
colors, and I choose e.g.

this pink, I apply this pink
to this backside phase,

then as it is still selected,

you can see here that
color for the backside

and this another default
style for the front side.

Here it is represented
those two colors,

the white and that blue
color for the backside.

So the thing here
is that it's very

common that when we are
drawing a sketch up randomly,

Our Faces take the
backside color when we

actually want that
front color towards us.

And then is when we
have to use that to

call reverse phases,
Let's do it.

E.g. here with the cube.

On the left side, we
have this cube with

all the phases using
the front color.

And on the right side,

we have just the opposite
example, my advice here,

and you will see
during the course

that I will do it every single

time is to fix this
situation immediately.

So it will become like

a habit for you to
reverse the phase.

Place the front color
to us, the camera, e.g.

here, if I click on this
face and I say right bottom,

and I go to reverse faces,

then this phase
is already fixed.

Then I should do the
same everywhere here.

I select all the faces,

right bottom reverse phases.

Here we are. Maybe you are

thinking what is the
reason for doing this?

Firstly, is because
it is very good

to have your drawing organized,

but at the same time,

having the backside color to us,

you might have bad consequences

in terms of performance
when you are

exporting your SketchUp file to

our rendering software
or our 3D printer.

Both of them use that
information for pointing

a normal vector towards the
interior or the exterior.

So it could end up in an error

here in a SketchUp actually
doesn't matter so much.

E.g. if we are applying
materials and I

will recover those
backside phases.

And now I'm going to
materials select.

Let's pick up e.g.

this brick antique texture.

I will select with three clicks,

all the entities connected here.

Then letter B for the Paint
Bucket Tool, one-click.

Here we have this texture
applied to the cube.

I can do exactly
the same to this

another queue and there
will be no differences.

So we can think that it is not

needed to do this reverse faces.

But as I already told you,

the problems will
appear when we export

this cube to our rendering
software or a 3D printer.

In my experience, not always
those problems will ACU,

but it does exist the
possibility of the error.

Another tool related with

this Reverse Faces is called
orient faces. Here, e.g.

in this cube, we can check

how this phase is
currently oriented,

but the rest are not.

Instead of choosing

every single wrong
phase and fix them,

I can choose the correct one,

right bottom orient faces.

And then the program
is intelligent

enough to recognize
all the phases

connected to our
selection and orient

them in the same direction
as our reference.

Finally, if I go to Styles,

I will collapse the entity Info.

Here, you will
find, first of all,

a thumbnail about the
default style with

those color I told you the
white and the blue one.

But my tip here is going to

Edit and here go
to face settings.

Here you will be
able to change and

customize that front
and back color,

creating your own style or

modifying the one you are
using at that moment.

So I'll click on

this color and I will
change e.g. this red.

Or I can go to the
color wheel and say

that I want this
red all the time

with the purpose of making

that backside color much more

different than the front color.

Furthermore, if I go to style
and I click this option,

displays said that
he using all same,

which can be found here as well.

Then you will be able
to spot Where are you

using that back side
color and then fix it.

E.g. in this cube,

where we applied
that brick texture,

three clicks, pattern,
reversed faces,

it is already corrected.

And then I can go back to this,

say that with textures option.

Now that brick texture
is applied inside

the queue for spotting this
backside color's faces,

we will be able to use as well.

And let's say automatic tool,

which is not native
from SketchUp,

it is an extension.

It is called solid inspector

and then it will be
easier and faster.

But we will see that when
we talk about plug-ins.

Now, it's time to say goodbye.

In the next episode,

we will jump to another block of

information and we will start

drawing in SketchUp using

the line tool and freehand tool.
