Hello people and welcome to this new class.

Inward, we're going to see a very,

very powerful tool which is called Follow me.

We will find it here in

the transformation panel under this icon, Follow me.

The description says follow

a path with asset-backed that phase,

but actually it has much more functions and features.

So let's start here with this model

in where we can see a path and a face.

So basically the tool is going to

extrude our surface along the path.

We have two ways for doing this.

The correct one and the incorrect one.

The incorrect one would be to hit

the tool and then go directly to our surface,

one-click and release and move our mouse along the path.

As you can see, we can do it using this way,

but we can find some kind of

problems when we want to turn the corners.

And the more complex the path is,

the more difficulties we will find.

The best way is to select first our path,

then hit the tool,

one click and release.

On our surface, everything will be done in 1 s.

We can see how this tool makes these 3D model

merging everything together perfectly in the corners.

And this is a very huge time-saver because MIN,

if we wanted to do this by ourselves,

we should add and remove material here.

And it could be very problematic.

In addition to this,

we have to take into account that

this tool is not working The asked

when our path is in contact with our surface like before,

but we can use it as

well when there is no contact at all.

Like in this example,

we have this path,

we have this surface,

and they are not in contact between each other.

So the mechanism will be the same.

We have just to select the path firstly,

then hit the tool and go to the surface.

One-click.

As you can see, that surface,

that kind of ring we had before has

been extruded along the path,

creating this kind of hold,

this kind of pipeline, right?

But this tool is not working just with linear paths,

but with circular paths as well,

or better said, closed paths like e.g.

this one, we have this,

we have this Eds,

we have this EDS,

and we have this Eds.

We have a square here and one profile I drew before here,

using this tool, we will be able to extrude this profile,

this shape, along this path.

First, we select the path.

Then we hit the tool on

one click on our say, here we are.

We can create these complex shape very easy.

And as you can see again,

on the corners, everything is

merged in a very smooth way.

However, we can use this tool as well without

using the atheists but using their surfaces.

I mean, control set when a step back.

And then if I want to select those edges,

that path, in order to do the same function,

I could click just on

the surface heat the tool

SketchUp will know that we want to

select the edges on the perimeter of

that surface and then one click on the shape again,

we have the same result.

In addition to these,

apart of adding material,

we can remove material using these.

Follow Me too.

Again.

I select the surface,

then I hit the tool.

One click on this surface, what is going to happen?

The extrusion along the path is going to remove

the material along these square one hit.

And here we have the result.

This is very interesting because

we can do this kind of stuff.

E.g. I.

Will use the Arc tool now,

one-click, hear, one-click here.

Let's say that our sales will be more or less like that.

We have the surface,

then we can again select

this surface in order to get the perimeter as a path.

Then we hit the tool.

One-click here.

We have here this another example in where we will do

exactly the same but working in another plane,

I will click the surface.

I will hit the tool.

One click on my profile.

We can create this kind of relief for,

let's say, a window.

Imagine that this surface, e.g.

is not solid, is glass.

So I go to material less and minerals,

translucent glass tinted, e.g. one-click.

And we have then this window with

this kind of sophisticated frame.

In addition to this,

we can create that frame around this perimeter

even when our profile is not in contact with that,

as we said before.

So one-click on the surface,

we hit the tool, one click on our profile.

And here we have that frame,

which is keeping that distance to that perimeter.

Finally, another feature of

this tool is the possibility to

create what is called surfaces

of revolution, e.g. a. Cone.

Say, imagine that we want to create a cone shape.

We can't do it by using the extrude tool.

Because if I want to do it,

I just can create this kind of triangle in 3D.

So we need this.

Kind of profile to turn around this circular path.

That is the definition of a surface of revolution.

So again, we select first the path.

It could be this surface.

If we want to select the circumference,

then we hit the tool one click on our profile,

and here we have our condensate.

Sometimes you will find that e.g.

here, it is not closed the ground floor of this comb,

then maybe we have to do it by ourselves.

I just have to draw with a line tool

one diagonal and then erase this line.

Now I could reverse phases.

Here we are.

However, when you are using this tool,

you can find some time some difficulties because e.g.

here we have these two cycles.

They are not in contact at all.

And we will use this cycle

on the ground floor as a path and

this cycle above it as the surface

that we want to extrude along the path.

So I select surface,

I hit the tool,

one click on my sake.

And here we have this sphere.

This is a very nice way for creating an atmosphere.

On this another example,

we have the same both cycles,

but the position between each other is different.

If we repeat the same process,

we select this cycle as a path.

We hit the tool and we click on this cycle in order

to extrude this cycle

along the path we don't have here on a sphere,

but we have this kind of ring along this cycle.

This is because of the relative position

between each other on this another example,

the center of the cycles not aligned along the blue axis,

as in the first case with the sphere.

And they are not aligned neither along

the red axis as in the second example.

If I repeat the same process,

I select this surface for

selecting the circumference as a path.

I hit the tool,

one click on my safe,

then you can see here

this new shape that we have generated.

If you wanted to understand better how this

safe or why does this say is like that?

We can go one step back and then use

the tool directly to our say, one-click and release.

Then we move the mouse along the path.

We can see how this path is being generated.

In this case, it is a little bit strange, in my opinion.

To finish this class, we will use this follow

me tool with this chest bone.

Remember that we worked with

this just pond in different episodes before.

You can use it now in order to create the 3D model.

Because again, if we just extrude this poem,

the result will not be good enough.

If I use the Post poll tool here,

one click and release,

we will create this kind of orthogonal extrusion,

which actually is not correct, right?

So we need to create here again,

a surface of revolution.

Furthermore, we have here a group,

the chest bone is inside a group box.

But even when our geometry is placed inside a group,

we can use the follow me to

the mechanism is more or less the same.

We have to select our path.

Secondly, we hit the tool and

then if we move the mouse to our sake,

we will find this forbidden icon because

the geometry is placed inside that group.

But then we click the right button,

edit group, we are already inside the group.

Follow me to remember the path we had selected.

So now one-click and release on the cycle e.g.

and we have the sphere.

The thing now is that we can't do it over and over again.

We need to go out from the cycle and

start again from the beginning, select the path,

hit the tool right button, edit group,

and one click again on the next surface.

Here we are.

And we should repeat this process three more times.

Once we have finished our chest poem,

we can delay to the surface

because we don't want the path anymore.

And here we have the result of

our chest bone modelled in a very nice way.

As you can see, this tool is super powerful,

much more than many people used to think.

I strongly recommend you to use it.

Practice with it with

different geometries because it is a little bit tricky.

And in the next episode,

we will see the last tool of the transformation panel,

which is this offset tool.

It is much more easier but useful as well.
