- We're going to take a look now at rotating and scaling
in our AutoCAD drawing.
So we're staying in our office layout drawing,
I've left it in the same state as it was
at the end of the last video.
And I'm going to zoom in now on this little office here
where we've got the desk, the chair and the computer.
So I'm just going to get the cross arrow over the middle there
roll up on the wheel a bit
so that we can see what we're doing.
Now, I'm just going to zoom out one click there
so that we've got a little bit of space
around what we're doing as well.
Now, we're going to do some rotating first.
Now, you'll notice that the chair
and the computer are kind of facing the wrong way.
That's one of those really old-fashioned computers
by the way, with the CRT monitor,
for those of you that remember them.
Now, what I'm going to do, is make sure
that my Polar Tracking is set to 45 degrees.
There's Polar Tracking, click on the little fly-out arrow,
make sure you're using the 45-degree increments
like I am there.
And then I'm going to select the computer first
and then it's a right-click again,
I'm using the right-click a lot at the moment
and Rotate is there on the shortcut menu.
Now, the base point I'm going to use,
is that midpoint snap there, like so.
And I'm just going to bring this round
and can you see, as I hit each 45-degree increment,
the little red computer there, is rotating quite happily.
So when I hit that increment there,
can you see the computer is now facing away
from the desk towards the chair?
I left-click and I've rotated that
through increments of 45 degrees.
Now, I didn't even need to know the angle,
the Polar Tracking did that for me
and I know that this angle here on the desk
is 45 degrees as well.
So that computer now lines up nice and neatly.
If you haven't got it dead center, just click on it,
it's a block, you can click on the grip
and reposition it slightly if you need to like that.
I don't need to, so I'm just going to hit Escape to deselect.
We're going to do the same with the chair now as well,
we're going to do a little rotate on that one.
So I'm going to select the chair like so,
again move away from the chair, right-click and Rotate.
So I click on Rotate like so,
base point this time, I'm going to go for the midpoint
on the back of the chair there
and then using Rotate
I'm just rotating the mouse in a circle
and getting those increments of 45 degrees.
As I come down to the right here,
you'll see the Polar Tracking kicks in
and it's an angle of 315 in this case,
left-click, there's the rotation.
Now, the chair isn't exactly positioned
the way I would want it to,
so again, click on the chair, click on the grip,
just move it slightly up.
Again, I'm using a 45-degree angle line there,
which is quite useful
and I'm going to click there like so.
It doesn't have to be perfect
but you just want it facing the desk.
I'm just going to hit Escape to deselect the chair now.
Now when we zoom out slightly, you can see now
that we've got an entirely spaced, neat and tidy computer,
desk and chair.
Now, over in the bottom left corner,
ideally what I should be doing,
is now selecting the computer and the chair, like so,
right-clicking and copying, using Copy Selection
and I'll use this corner of the desk here as the base point,
take it down to this corner of the desk here
and click there, Enter to finish,
I've quickly and easily copied
my rotated computer and chair.
Quick and easy to do.
So now, we need to have a little think about scaling.
Now, I'm going to utilize some little tricks here,
I'm going to use Copy
and I'm going to use a bit of Object Snap Tracking as well
before I scale the plant in the office.
So I need to copy the plant first.
I'm going to select the plant, like so
and I'm going to right-click
and I'm going to Copy Selection off of the shortcut menu.
I'm going to click in the middle of the plant,
normally an intersection and then I'm going to come up here,
now, I'm going to Pan and then roll up on the wheel
a couple of notches so that you can see what I'm doing.
I'm going to hover over the midpoint snap there,
the midpoint will come up
and then I'm going to hover there
over that midpoint snap there.
That's object Snap Tracking, I'm not clicking yet.
And as I come up can you see, when they intersect
I get two object tracking lines,
polar tracking lines kicking in?
And you can see the cross there with the green, dashed line.
So what I'm going to do is left-click, Enter to finish
and I've done a copy there
but my plant is too big for my desk.
This is where Scale comes in.
So I'll zoom in again, just select the plant
and again, I can right-click, Scale is on the shortcut menu,
select Scale, again, a base point.
Go for the center point there,
it's normally an intersection, left-click
and then as I move the mouse,
can you see I can make it bigger and smaller?
Now, the scale factor I need is going to be note, 0.6.
I'm making it basically 60% of its original size.
Press Enter and you'll see there after I've done that,
it fits nicely there on the desk.
I'll roll out on the wheel, a couple of notches to zoom out.
So now I've got a nice, small plant, a desk plant
on the desk.
So I'm going to select the smaller plant
and again, right-click, Copy Selection,
go for the base point in the center, the intersection
and then what I'll do here, is maybe put that down here.
Now, hang on a minute though,
that means I've got to mess around
using Object Snap Tracking.
There has to be a quicker way.
Just hit Escape a couple of times, select the plant again,
right-click, Copy Selection and use an easier point
as the base point, a corner of the desk.
There's the endpoint snap, left-click,
there's the endpoint snap there,
the corresponding one on the other desk, left-click.
Enter to finish, like so.
Now there's one more rotate that we need to do.
We need to allow somebody to use this desk
without having to climb over the desk, to get to the chair.
So we need to rotate all of this in this particular corner
of the office.
Now, we're going to look at that using some of the commands
as we work through this particular chapter.
There's one particular command
that is just extremely useful for that.
So let's move on to the next video
and that now covers in a nutshell, a lot of copying
but also rotating and scaling in your AutoCAD drawings.
