Original subtitles

In this episode, we will talk about the navigation.

So first of all,

we have to understand

these three axes that we can see on the screen.

One is blue, another one is green,

and the last one is red.

They are representing the three-dimensions

that we have in this space.

The blue one, a vertical dimension,

most of the times represented by the letter set.

And then we have these two ones,

the green and the red for

representing the horizontal dimension.

The letter for the green one is the letter Y,

and the letter for the red one is the letter X.

So as you can imagine,

this axis will be all the time.

Our references for don't be

lost when we are orbiting e.g.

because at the end it is like if we are astronauts into

space and then we have to

be patient in order to be able to,

let's say, control our movements

or the movement of the camera as to prefer,

in a very accurate way.

I would like to add as well that

every axis continue after the region,

which is this point I am marking right now with mouse.

So this lines, this axis continue with a dotted line

which represent the negative part of that dementia.

Furthermore, if we look further,

we will see the line of the horizontal.

Above that line, we have

the sky in a blue color right now.

And below that horizontal,

we have this gray color.

All of the canvas at the end is representing a sphere.

At this very moment,

we don't have color for the plane of the ground.

Right now, that plane is completely transparent.

So we can see that semi sphere

below the horizontal in that gray color are,

we can see that another semi sphere

above that horizontal line in that blue color.

In the next episode,

we will talk about the templates and in a very rapid way,

I will teach you how to change

those colors in case that you don't want it.

But continue with this lesson

in where we are focused on the navigation,

we have to pay attention to this group of buttons we

have here where we can find

this first option called orbit,

which actually I am already using it without clicking on

here because I am clicking on whole the will of my mouth.

Then I click I hall and I moved for

understanding better these movements of the camera,

I will draw a queue.

Once we have this cube as a reference,

if I click a whole,

the will of my mouse and I move my mouse to the left.

What is happening is that we are actually

looking at the right side from

my point of view of these Q, right?

So if I move now the mouse to the right side,

the other side of this cube is visible.

Besides, if I move the mouse now to the top,

as you can imagine,

what is visible now is the ground floor of this cube.

So the opposite all the time.

And if I move my mouse down,

then I am Watson at the top of the queue.

So I recommend you to draw this cube.

It is very easy.

You just use a rectangle

and use the extrusion, push and pull,

and be very conscious about how this orbit tool

works in a sketch will help

you a lot for the next lesson.

Apart of this orbit tool,

which is very, very important,

we have this pan tool,

the shortcut for the pen tool

is the letter H in your laptop.

And then what I'm doing is not

rotate the camera as I was doing before,

but moving the camera vertically or horizontally,

but I am keeping more or less the angle of the camera.

Next option is the soon using the wheel of my mouse,

I can scroll in or scroll out.

But if I want it to be more precise,

then I could use these two tools.

The first one called soon, one is clicked.

If I use the left button of my mouth,

I click and hold,

and I move the mouse,

I will get closer,

but in a very soft way,

softer than if I am using the scroll of the mouth.

So sometimes can be useful.

Next option, Zoom window,

will allow us to create a window clicking and holding.

And then I will assume that

content inside that window when I released,

then I have some that specific area.

I will do it again.

With this woman, I create this window around her.

And when I released,

then you can see that we have

some the woman at her maximum size in our screen.

Next option for a good navigation

is this button called zoom extents.

This is a very useful bottom in my opinion

because it will help us a lot to recover our,

let's say, perspective drawing

when we are quite lost, e.g.

imagine that we are here now, maybe too close,

and we want that perspective in

where we can see everything.

So we can click on here.

And then the camera,

we'll capture the complete drawing at its maximum size.

That is very, very nice because e.g.

if I have another object,

let's say a line here and we were just

pointing this woman and I use again this zoom extents.

What the camera is going to do is to capture

all the drawing at

its maximum size, as I told you, right?

So you can see here how our drawing

now is not that big because the camera

has to go farther in order to get

that line which was hidden under these Default tray.

But it is there so many times.

If you click on the Zoom extent and you

realize that the camera goes so far,

it is saying to you that something,

it is drawn and maybe you can't see it.

Anyways, I will erase

this element and let's jump to the next option,

which is called Previous.

These previews is kind of undo,

but just related with the movements of the camera.

So we will go one step back in our camera history.

I click on it and you can see

our previous step was here pointing this woman.

Finally, it is important to

point out here in this episode

that we have this toolbar which is called views.

I wouldn't put it here.

Now, which is going to be super,

super helpful for navigation.

I mean, we don't have to all the time try to place

the camera manually using

these tools that we have just learned,

like orbit or pan or zoom extents,

we have this automatic positions

of the camera right here in this toolbar.

And the first one is the isometric view of the model.

Click on here, then we have this isometric view.

As always, we will have to

keep in mind the position of the axis.

Then we have this another option called top in where we

will be able to what our model from the top one-click.

And here we are.

Then we have front,

right, back, and left, e.g.

if we start clicking on front,

you can see how the camera

moves exactly to this position.

And again, pay attention to the axis in

order to know where exactly are you.

If I go to right,

then the movement of the camera

has been towards the right side,

then back, we continue moving to the right and then left.

So this is going to be super helpful as I told you.

I'm finally we have this another option which is

just select one face of the object right button.

And then we have this option called Align View.

If I click here,

then the camera is going to be aligned with

that phase Following that orthogonal line.

To finish with the navigation,

I would like to mention

another tools that we can find if we

move over a camera here we will find these two option,

parallel projection and

perspective when we're navigating.

It is very, very interesting and

useful to switch between these two options.

Normally, we will be working on perspective.

But if I select parallel projection,

you will see that everything is like if we are

working in a dihedral system.

So if I use e.g.

this top view, all the measures will be real.

I mean that it is like if

we're doing a planned floor here,

we don't have perspective at all.

All the lines are parallel between each other.

So this could be very interesting for generating,

as I said, gland floors or elevations, e.g.

if I move to this front view, etc, etc.

If I go again over camera,

we will find here a third option

called two-point perspective.

But this upsilon, Let's say

that it's not that important for

the navigation and we will see it in

a more advanced stage of the course.

Good, we will finish the class here.

We will talk more about navigation.

This is the beginning.

And of course,

practice will make you more and more wetter.

And at some point,

you will not have to think is like

driving a car and the movements of

your fingers and your mouth will be

super accurate even without thinking.

Time to jump to the next episode where we're

going to learn how to use the selection tools.
