Hello people and welcome to this new class in where

we're going to talk about a very important tool.

It is the pool tool.

We will find it here.

It is part of the transformation tools and

one of the most important tools

without any doubt in SketchUp,

as you can imagine, it will help us to extrude

our 2D surfaces in order to achieve 3D models.

So we will need all the time to work

with surfaces, not with lines.

Here we have a queue.

This cube is based on different surfaces.

So we could double letter P,

that is the gut.

And then if I hover the mouse over any of these surfaces,

we will see how these surfaces become full of dots.

In that very moment,

I can click and release,

move my mouse and extrude my surface.

I could type in the length as

well in order to be more precise, e.g.

let's say 1 m wave of the queue was 3 m.

And now we have 4 m, that is E3.

And we can call this extrusion

positive because we increased the volume,

but we have as well negative extrusions, e.g.

if I draw a cycle on this phase,

in order to be more precise,

I will use the guidelines

to find the center of this surface.

One parallel here across this mid point.

The same in the opposite direction.

We have the intersection here,

then letter C for the cycle,

one-click and the radius,

let's say 1 m e.g.

now we have this surface inside

the cycle and this another surface outside the cycle.

If I use the Post poll tool now,

I select first the surface,

post pool, one-click and release.

And I move my mouse,

we could either extrude in a positive way,

that surface or in a negative way.

Because now we are subtracting volume.

If we wanted to create

here a perfect hole through this Q,

we should extrude this cycle till this other side, right?

Till the other side of the cube.

So we could choose as our reference,

any point of this side of the cube, including the edges.

So I recommend you when

you are here and you want to create a

whole instead of orbit around the cube,

you can choose any point of

that side using the address e.g.

here, click and you know that the hole has been created.

This is like that because as you already guessed,

the push-pull tool is working through

the orthogonal vector of any surface, e.g.

if I incline this side of the queue,

we will be able to appreciate this orthogonal extrusion.

More clear, let's draw the perpendicular

first with the line tool,

one click and release.

And then I check where is that perpendicular here in

this pink color perpendicular to

face here we have this orthogonal vector,

which is the one that the Post poll tool is using.

Here we can see it.

Let's erase the guidelines and let's talk now

about another function that we can use with this tool.

We have positive extrusions.

We have negative extrusions,

and we have a third option in where we will be

able not to increase the volume,

but at another volume letter P,

I select the surface, click and release,

and in one moment I have to tap Control key.

Then the plus icon will

appear next to our post poll tool.

And then we can say that this extrusion is independent.

Second click here, and we have generated

independent surfaces which can be extruded as well.

Imagine e.g. that we are

working with the room of a house.

We have this first volume and we want now to

create a kind of rock and then play with it.

If I extrude this surface in a positive way,

we are increasing the volume and

the surfaces in a continuous way.

But if I click Control key,

then from that surface as a reference,

we'll start a new and independent volume,

which will be our rod.

This time, I will type in here the length of this rod,

Let's say 0.5 m.

And then I can select any of the surfaces of

this new volume and continue extruding it, e.g.

for creating here a cantilever.

Here we are.

Anyways, we will practice with this tool

during all the course and we will

learn more functions about

this boost pool tool when we

go through the plugins episode.

Because I have to say that there is a very,

very well-known plugin which will allow us to

extrude things in a very creative way,

not the AST playing with these orthogonal vector.

Anyways, we have to

muster this native push-pull tool from

SketchUp in order to use in

the future that interesting plugin.

We finish this class here and in the next one,

we will start learning about this move tool,

which actually, apart from moving things,

is able to copy things.

So we can say that it is the move

and copy to in SketchUp.
