- [Instructor] We're staying in our officelayout.dwg file
and we're going to take a look now
at the mirror and offset commands in AutoCAD.
Now I mentioned previously
in previous videos that we're going to look at a way
of freeing up this desk here
in the bottom left corner,
because at the moment somebody needs
to hurdle the desk to get access
to the chair and sit at the computer.
So we'll look at that one second.
What I'm going to do is show you a simple mirror first
to fill up this cubicle here top right.
So we're going to select the plant,
the chair, the desk and the computer like so.
Make sure you select all four objects.
We're then going to right click
and have a look at shortcut menu.
And you'll notice that Mirror is not
on the shortcut menu in AutoCAD.
So we have to physically go up
and click on Mirror in the Modify panel.
So just hit escape once,
that'll close the shortcut menu
and keep the object selected.
Then pop-up to the Modify panel.
It's on the home tab on the ribbon,
and there's Mirror right there.
We've already got the object selected.
So when we click on Mirror,
it'll prompt us for the first point of our Mirror line.
So we need to zoom in a little bit here.
So get the cross here over this bottom area
of this internal wall here.
And we're going to go down to this little midpoint snap there,
the midpoint snap of the internal wall.
Left click.
And as you come vertically upwards
and zoom out maybe a couple of notches on the wheel,
you can see as you come vertically up
that polar tracking line,
all the way past the external wall there
keeping the tracking line going,
there's the tracking line there.
You can see that our mirrored objects are appearing.
Left click on the polar tracking line somewhere
for the second mirror line.
You'll then be prompted,
do you want to erase the source objects?
In this case, no I don't.
So select no on the menu and there's our mirrored,
obviously desk, chair computer and plant.
So we've occupied that top right area of the building.
Now, what we need to do here you'll notice,
is mirror this desk and chairs
in the bottom left corner.
Zoom in by positioning the crosshair like so,
and just roll up on the wheel a couple of notches.
Now we need to mirror this particular desk in situ.
We haven't got a wall to mirror it about.
So we're going to select the plant,
the desk, the computer and the chair like we did previously.
It's then a right click and recent input this time
because remember we've used the mirror command
or I could just use repeat mirror.
Either of those would work.
I'm going to go to repeat mirror at the top there
and there it is click.
It'll now ask for the first point of the mirror line.
Now I've been a bit savvy here
when I've created this drawing for you.
This line of the desk is actually halfway
along that wall there.
So if you use that endpoint snap there and left click,
and then come down to that endpoint there and left click,
you'll see that it's mirroring exactly
into the opposing corner of the cubicle.
Now when you are asked to erase the source object
you're going to say yes this time
and you've mirrored the objects
but you've got rid of the original objects.
Now people can get to the desk you'll notice.
Last but not least with the mirror command
what we're going to do,
is we're going to mirror into this cubicle here.
It's going to be a repetition of what we did up here.
So desk, chair, computer, plant, like so.
Right click.
And again we can repeat mirror or recent input,
either will work.
I'm going to use recent input this time.
And again remember to use
that little midpoint there on the wall.
Click drag horizontally through
to the left using the polar tracking,
click on the polar tracking line
for the second point of the mirror line,
erase source objects?
No.
And now we've completely occupied
our little office with our desks,
our chairs and our plants.
So that's using the mirror command.
Make sure now in the Layers panel on the layer dropdown,
you are using the walls layer.
It's down near the bottom.
Click on the word walls,
and we're just going to draw some lines coming off
of this top left corner
and we're going to utilize the offset command a little bit.
Now, what I'm going to do is draw a line.
So there's the line command on the draw panel.
And I'm going to come off of this corner,
click and go horizontally all the way
across there to the left.
Again make sure the polar tracking kicks in.
So, you know the line is horizontal
and type in 2400 as the length
and enter to finish like so.
You can see the line there,
it's coming out that far.
We're then going to come vertically downwards like so,
making sure the polar tracking kicks in again.
Type in 2400 again and press enter
and then press enter again to finish the line command.
See we've started to create a new wall
in that top left corner.
We're now going to use the offset command
to get the thickness of the wall.
So we're going to go up to offset here
on the modified panel there's offset.
Click on it,
come into the drawing area
and it requires an offset distance.
I'm going to type in 150 and enter.
I'm then going to select this line here,
click on it and notice it goes a blue color.
And I can then choose which side I want to offset on.
I'd like you to offset to the inside
so the brown line will be on the inside.
Left click to confirm that direction.
We're going to do the same with the top line here,
click on it,
come down which you want it inside
as you can see outside wouldn't serve any purpose.
Come down here like that for direction,
left click again and then enter to finish.
We now need to just quickly tidy up those lines.
This is a little bin store for the outside of the office,
so we need to do a bit of trimming.
So we'll go to the Modify panel,
just click on trim there,
and you're just going to pick
these two little line segments here,
one and two like that.
Enter to finish.
One more little line to draw,
click on the line command,
and we're going to go endpoint snap, endpoint snap
and enter to finish.
There's our little bin store added
to our little office set up there in our AutoCAD drawing.
