Hello everybody.

In this class we will talk about

another important concept in

SketchUp as groups and components.

So first of all, you can see on

the screen that we have a rectangle and a circle.

We know that both of them are based

on surfaces and lines as concerns.

So let's just start choosing e.g.

this circle and moving it following

the red X for keeping that cycle on the ground floor.

And eventually I will place that cycle on the rectangle.

Both of them will be occupying the same plane.

Here we are. And what is going on here?

We have an intersection between both sets.

So now we have an independent surface here,

another one in the middle,

and the last one here,

the three of them are independent,

so we can choose it and create 3D models from each one.

The same thing happens with the lines.

All of them have been cut and now are independent. Okay?

This is something that sometimes will be helpful for us,

but other times could be very

annoying and we will not want that to happen.

So the question here is,

how can avoid these to happen?

If I click Control set for undo this movement,

and then I select the cycle and

I say right button make group.

Then you will see this box

around the figure, which means that,

that geometry has been placed

inside a kind of transparent box.

We have to think about groups as boxes,

transparent boxes in where our geometry is

protected to blue with

the rest of the geometry in our drawing.

So now, once the circle is selected,

I click M for moving this entity.

One-click here, I move the cycle along

the red X tilde the corner

exactly the same as I did before.

Another click here.

Here we have the cycle placed

on the same plane as the rectangle.

But now if I select the selection tool and I

try to select those surfaces and lines.

As you can see, the result

now is completely different because

the cycle is protected and

then it is not blue with a rectangle.

So I can move that charcoal

independently without the fear

about create

intersections between the different geometry.

Our cycle is independent inside that box

and our rectangle remains untouched.

So this is the main purpose about creating groups.

Furthermore, if we wanted to apply

changes inside our groups,

we should go to the group selected.

You will see how our box is now made by a dotted line,

which means that we are already

inside the box, inside the group.

So we can touch our geometry and we can work

use while making the transformation

or the changes that we want.

E.g. here I stood that cycle

in order to create a cylinder.

And then the box is adapting to that new geometry.

If I wanted to go out from this box, from this group,

then I would go to

the selection tool and I click out of the group.

And here we are.

What about components?

Components is like a group with more properties.

So our geometry will be protected by a box as well.

But it will have,

as I said, more properties.

Let's create a polygon, e.g.

this hexagon.

I will click on the surface right button river

faces because I want this white side towards me.

We will talk about this in another class,

and then I will place this geometry

inside a component or say it in another way.

I will transform this geometry into a component.

For doing this, I will select my geometry right button.

And instead of saying make group,

we can say make components.

We have this option here as well.

The main toolbar, which is

exactly the same Make Component.

Then we have this menu create

components in where we can write a definition,

name, description, and we have more different options.

We will see all of them in

a specific class about components.

But now I will say just create.

Once the component is created,

you will see as it

happened with the groups, this box around,

which will protect our geometry from

intersections with other geometries till now,

exactly the same as with the groups.

So if I move this element to this corner,

again, the rectangle will keep untouched.

As it happens with our hexagon.

But we have here a component and not a group.

And the main property about components is that

if I copy any of them, Let's do e.g.

three copies and I make any change in any of them.

It doesn't have to be that change in the original one.

Let's do a change, e.g.

in this second copy, I go in,

I select the surface,

I click for post and pull, click unreleased.

And I create this 3D model.

As you can see already,

these changes inside this component

is affecting the rest of the copies.

So now I will click Space key,

one-click outside of the components.

Here we are.

As you can imagine, the use of components in

SketchUp is going to be key for drawing,

let's say in an intelligent way.

Because many times we will find

modeller elements and we will need

that our changes will be

applied not just in that geometry,

but in all the elements similar to them.

I'm talking about windows,

frames or doors or bathrooms, PLRs, etc, etc.

So we will finish the class here.

And in the next episode,

we will talk about another important concept,

as it is the outliner Default tray.

We will find that here.

And it will help us to understand

better the structure of our drawing.

And I'm talking about

these three elements that we have seen already.

The first one would be simple geometry or free geometry.

It is free because it is not inside any box, e.g.

this rectangle we have here.

And other elements would be groups.

And the third element would be components.
