Hello people and welcome to

this new exercise in where we're going to practice

our drawing skills by modelling

this kind of drill that we have here.

So first of all, let's analyze

this image which is attached with the course.

And we can find that we have on the upper part,

our ground floor of this that say industrial object.

Then on the bottom of the image,

we have a profile section plane.

And here at the right side we

can see an axonometric view.

We have measures, so we have

everything we need to model it. Here.

Of course, it is.

You how to draw it.

I will do it in one way,

but there is a lot of them.

Maybe you can find one even more better or maybe worse.

So feel free to follow your intuition.

Maybe you will make some mistakes and you have to

go back and then draw it again.

But that is a good process for getting better and better.

So me, I will start by

drawing the plant floor, first of all,

but before any step,

I will re-scale this image

in order to be more comfortable.

We know how to do it perfectly.

Tape measure tool, letter T for the shortcut,

if we find that icon of the guideline,

we tap Control key.

We don't want it right now.

We can go over camera, parallel projection,

top view, I will use this measure 50.

It seems that here it is talking about

millimeters because this piece seems to be kind of small.

But I will work during

all the exercise in meters, not millimeters.

And at the end, when it is already done,

then I will re-scale.

I will resize the object into millimeters.

This is because if we are working in millimeters,

SketchUp can have some kind of difficulties or errors.

So it is better the way I just told you

work in meters and then re-scale at the end.

So first click here, second click here,

we introduce the correct measure,

50, and you want to resize the model.

Yes, zoom extense, and we

have the image now in the correct size.

I will move it.

Let's start. I'll use some guidelines.

This is not needed and you can

draw your drill wherever you want.

But I think it is a little bit

easier for being, let's say,

organized to follow with the guidelines are plants.

And now if I check this floor plan,

I can see that I have 50 here.

Then we have here a radius of 15.

And here this distance is

again 15 because of this radius.

So 15 plus 50 plus 15 total API,

we have a rectangle, 80 m long,

ten plus ten plus ten, 30 m width.

This will be my first drawing. Rectangle.

One-click AT semicolon.

Here we're now letter T for the guidelines.

I can check here that we have ten,

then a whole and ten again,

this whole is this hole here.

So one click on the green axis,

I type in 10 m.

And again, 10 m. Perfect.

Now this hole, it seems that ends here.

And the distance, the depth of this hole is this radius.

Multiply it by two, right?

So if we have here 15 m radius,

then we need 30,

the diameter more than the radius.

One-click here.

I type in 30.

Perfect. Now we are ready for

deleting this piece of the drawing.

I can use the rectangle again to be faster.

One-click, one-click letter E for heating the eraser.

And I delayed this phase.

This side of the drill,

the right side is already done in my plant floor.

Let's go with the left side.

We have here a cycle, this cycle.

This cycle.

If we are looking at a piece from a top view,

I will draw here a guideline for you.

In order to understand better the drawing,

we need to be able to mark the center of the cycle.

Because actually we have cycles.

We have this little one and we have this big one.

The distance from this margin to

the center of the circle is the radius 15.

And it seems that it is placed just

in the middle of the width of the piece, right?

So we have everything we need guideline,

one-click 15 m enter.

I didn't draw a guideline,

but a point is a point.

I don't want a point,

so I can select it and delete it.

And let's repeat this axial letter T,

one click and release 15.

Here we are.

And then here another guideline,

one click and release.

And I look for this mid point,

perfect, here in this intersection.

We have the center of our cycles.

Let's check the drawing again

because we have a big cycle,

15 m radius and then this little one.

And we know that the radius is going to be

five because it is one-half of ten, right?

The diameter would be ten,

this diameter, but we need the radius.

So the radius is one half of 105.

Okay, let's draw it.

Cycle sites 50.

Let's start with the little one.

One-click unreleased.

We said that the little one is 5 m radius,

five enter and the big one is 15.

We can introduce the measure or we can do it graphically.

We know that the radius is going to be

tangent to here and here and here.

So second click Space key,

and now is high time for erasing the left overs letter E.

And one click on this.

And this is the relaxing part in where I

delayed everything that I don't need.

Pay attention that I have to delete as well.

This phrase, because here we have

a hole and this half of the cycle as well, letter e.

Once I have the floor plan perfectly drawn,

I would say that it is time for Extrude my drawing.

Letter P for Post poll tool,

I can orbit one-click unreleased.

And what is the height

of this model for knowing the high,

I have to check,

not the floor plan,

but the profile, right?

The section plane.

This section plane is talking about

this phase that we can see in the axonometric view.

So if we trust the radius,

we know that the height is going to be 30 m,

the diameter, again, know

the radius and the height would be the diameter.

So again, pause, pull, one-click, unreleased.

And I type in 30 m,

I can erase these guidelines.

I don't need them anymore.

And now I will rotate my image because I

want to pay attention to

the section plane nodes to the ground floor.

I selected Rotate, tool,

one click and hold down.

I select the correct plane for the rotation.

The red color for the protractor is okay.

I released second click and I type in 90,

90 degrees than selection tool move.

And I can move this image in a position in where I

feel comfortable for drawing

because I need to check the measures.

It could be there. This is up to you.

So we have a cycle here, kind of hole.

This hole is this hole which goes

through all the width of the piece.

And then we have here a kind of bite,

which is gonna be a little bit more complicated.

You will see because we will have to

use here the solid tools.

So let's start with this EC part.

We need to draw this cycle.

When we draw a cycle,

first thing we need is the center of the cycle.

The center is going to be separated

of this margin by 15 m,

the radius, and it is placed

in the middle of the height of the piece.

So it is easy to draw guideline, one-click here, 15,

another guide line parallel to this line,

we look for the mid point,

and here in the intersection,

it displays our center.

We have here again two cycles,

a little one and a big one.

The little one, the diameter is ten,

and the big one, the radius is 15.

So let's start with

the little one letter c For the cycle 1-click,

the radius is going to be

five and the big 11 click on the center.

And we can do it graphically because we know

that it should be tangent to this side.

Perfect time for Post poll tool P,

when this face lights up, one-click and release.

And we know that if we move now

to this right side, look what happens.

We are creating a kind of cylinder,

but this is not what we really want.

We want to create a hole in

this kind of leg and another hole in this,

another leg of the piece, right?

So let's do the whole once at a time.

Then my second click should be e.g.

here, in any point of this phase,

and the hole is created now with a push-pull selected.

If I hover over these phases,

you can see how this face lights up.

So one-click here and I'll do

a negative extrusion because

this piece of geometry is not needed at all.

So I can delete it, doing,

as I told you, this negative extrusion.

So we are done with this leg and we

need to do exactly the same here.

We could repeat the same process

by looking for the center,

draw with the cycles and so on.

But maybe it's more intelligent to copy

the geometry that we have already drawn.

So I could select this half of the cycle.

I could add to my selection this cycle as well.

So I hold down shift key,

one click on this cycle.

The selection that I want to copy them.

Letter M for moving,

I select e.g. this point.

And this is very important because you

will need a point which is repeated

there in this and other leg in order to place

my selection exactly in the same position.

So one-click here, then look that I am moving

my selection and my geometry is distorting a lot.

But when I click Control key,

I'm doing a copy and the copy is not

glue with the previous geometric.

So I move this copy to this another point,

these twin point of this,

another leg, second click and release.

Here, our geometry drawn in a faster way. Right?

Now we have the US to repeat

the negative extrusions letter P.

And look that this surface is perfectly marked.

It is separated, isolated,

so we can do that and negative extrusion.

Let's do it.

But this inner cycle is not isolated.

I could say that it is a kind of error of

a SketchUp because we did everything right.

This is something that can happen time to

time and we just need to find solutions.

So we need to delete

this cycle and we can try to repeat it again.

Letter M, one-click control for doing a copy.

And now it works.

If it doesn't work,

don't panic because we have

many ways for drawing in SketchUp control set.

And I will do it in another way, e.g.

letter T for the guideline,

one parallel to this line.

Second click here.

Then I have here the intersection point for

my center letter C, one-click here,

5 m. And we have

this face drawn in a completely different way,

then letter P, one click and release.

And we know that that hole has to finish exactly on this,

another phase of the piece.

So here we have the whole perfectly done.

Let's erase all the guidelines in

order to sort out our drawing.

We don't need this half of the cycle neither, okay?

Um, the only thing missing now is this hole, right?

This kind of rectangular hall,

which if we check the axonometric view, is this part.

For doing this whole,

as I told you before,

we will need to use the solid tools.

First question would be why?

And the answer is because we

have a complex geometry here.

We have a kind of curve we have here.

So if we try to do here and negative extrusion,

like we did with this whole,

we will find that is not possible.

A SketchUp won't allow us to do it.

But first of all, let's use

the guidelines in order to be precise.

We know that this height is 1,010.10,

and here we have 30 m width.

Let's move this image down here.

Letter t, one parallel 10 m distance,

another 10 m. Perfect.

And then we have this 30 m,

15 from the center.

So from here, 15 front view.

And we already looked at here,

I committed a mistake because

those guidelines are not touching this phase.

This is because when I was using this front view,

my guidelines were taking from the red axis.

I did something like that.

So be careful with that.

When you are using the top or the front view,

I will erase them.

This vertical guideline, it seems that it's okay.

And then I will draw again this horizontal guidelines,

letter T, 10 m, 10 m, perfect.

Now, if I use a rectangle,

you will see that I can

make that extrusion push-pull tool.

And as you can check,

It's not possible to do

this kind of negative extrusion here,

not even here, because I will find

that hope that vertical cylinder.

So I need to work here with solid tools.

So let's go over this upper bar, right button.

We look for solid tools,

one click and release.

Here we have its two set.

So we need now to solids to interact

between each other and create this kind of bite.

One of those solids will be this piece and the

other solid will be a kind of 3D rectangle,

which I will use in order to bite this first solid.

So first thing is to create here a group right button.

Make group one.

Click in any of these buttons, e.g.

here, subtract.

And if I hover over this piece,

I can find a number,

which means that the tool is

recognizing this group as a solid.

It doesn't have any kind of error.

Okay, then let's draw the second solid here.

We have perfectly marked with

these guidelines the height of that rectangle.

So I will use them letter P.

I will create this 3D model

when this kind of graphic errors

appears in SketchUp normally is

because we are using the parallel projection view.

And then the graphic card has some kind of problems.

Sometimes if we go over perspective,

you want find these problems.

So that's work now with the perspective mode.

We have that rectangle, three clicks,

right button, make group.

Let's check now if the solid tools

recognize this element as a solid, it does perfect.

Now I have to place

this rectangle in the correct position here.

Now I have to move it along the real axis.

Here. Perfect. All is ready for doing the subtraction.

I need this rectangle to bite my drill, right?

Then I need that rectangle to disappear after the bite.

So the tool that I need is subtract,

subtract first, saw it from

second and keep only the result in the model.

This is exactly what I need.

So I hit substract here.

The order is very important.

The one who bites is the rectangle.

So first solid, the rectangle, one-click.

Second solid, the drill.

Here we are.

It worked perfectly and the drill is finished.

We just need to erase these guidelines.

And here we have a group with this drill perfectly drawn.

Now, the last step is to place this drill on the origin.

So letter M one-click here origin and resize,

rescale this drill because

we were using during all the exercise meters.

So letter T, one-click here,

Control key if it pops up the guideline icon,

second click the lens.

Of course, it is 80 m and it has to be 8 mm.

So we have to type in a t and the unit is millimeters.

You want to resize the model?

Yes, it seems that the real disappeared,

but no, the thing is that now is very, very small.

We can use the zoom extents.

And here we have our drill perfectly resides.

We can measure it 0.08 m,

which is the same as 80 mm.

Our image was resides as well.

So this exercise is done.

I know that the difficulty increased quite a lot,

but I am totally sure that you are able to be

successful if you have any doubt or any problem,

don't hesitate to leave

a comment and I will respond to you as soon as possible.

And we will continue in

the next episode with another exercise.
