- [Instructor] We've got a slightly different drawing
for you now in this chapter,
it's now Office Layout_3.dwg.
When you open it up in the model tab
and zoom to extend you'll notice it looks subtly different
to previous Office Layout drawings that we've been using.
There's a little bit more information on the drawing.
And we're going to take a look at some of the modify commands
available in AutoCAD.
In this particular case
we're going to look at Trim and Extend.
So you'll notice up here
on the sort of top area of the drawing,
there's a green circle and some horizontal orange lines.
Now they're on a hard standing layer
and what we're trying to do,
we're trying to create a decking area
in this garden area outside the little office building.
What we're trying to do is create a little sort of area
of planting and hard standing
so that people can utilize it on a break, on a lunch break.
When the weather's fine
you can perhaps have a business meeting outside
in the fresh air.
For example, after the last few years of the pandemic
it would be fantastic obviously to get out
and enjoy the fresh air with your colleagues, for example.
So let's zoom in on the area
get the cross here over the area and roll up on the wheel
a couple of notches like so.
Now what we want to do with this particular
sort of hard standing is these lines represent
some decking blanks.
And what I want to do is I want to extend them across
to this spline here,
so that we've got this nice curved bit of decking
just to sort of take the sharp edges off, so to speak.
And we also need to trim back the decking here
because this circle will form a bit of concrete,
hard standing and we'll have some planting
going around it as well.
So let's have a look at the Trim and Extend commands.
They're on the Home Tab, on the ribbon, in the modify panel.
And if I come up here and click on the Flyer,
I've got Trim and Extend.
We're going to use the Extend tool first.
So there's Extend there, like so.
And we're going to use this spline here.
Now, in order to do that in AutoCAD 2023, the latest version
and also the last two previous versions
you do need to right-click first
and select your boundary edges, like so.
And then I select that as my boundary edge and click.
I then press Enter to confirm that selection,
and I get prompted now to extend or Shift + select to trim.
Now, I don't want to trim, I want to extend to this spine,
to get this nice curvy edge of the decking
for the hard standing.
What I can do though, is I can type F for fence
which is quite handy,
rather than having to extend every single horizontal line.
If I now press Enter,
I can just click down here,
put my fence through those lines.
Can you see them previewing?
And then click up here.
Press Enter to finish.
And that's our extend done.
And our decking has extended beautifully to that spline.
So what I'm going to do now is I'm just going to
press Enter to confirm our extend and that's done.
Now, let's go back to the modify panel
and click on the Flyer again, but select Trim.
Similar workflow, we're going to right-click again
and select cutting edges.
Our circle is going to be the cutting edge this time.
And then I'm going to press Enter to confirm that selection.
Now we're prompted to select the object to trim
or Shift + select, to extend.
So you'll notice I can Shift + select
between trim and extend and they're kind of interchangeable
if I want to use that function.
What I'm going to do a again, like I did for the extend
is I'm going to type F for fence and press Enter.
And then I'm just going to come down here
and get my point just here
in between the two lines of the decking,
click and drag upwards.
Can you see they're all trimming?
And then when I get near the edge of the circle there
just click again, press Enter to finish.
And there's my trimmed decking
ready for my circular concrete outstanding.
I'm going to press Enter there now just to finish.
And one last thing you may have noticed
we seem to be missing a decking line.
Now, if that's happened, that's fine.
Don't worry.
We can do a little bit of extending again.
No problem at all, but we need to offset first.
So what I'm going to do
is I'm going to offset this line here.
So I'm going to go to the Offset command on the modify panel
and we need an offset distance of 100.
Trust me, I know these things.
And we're going to just click on this line here,
move upwards, click once and then Enter to finish.
Now you'll notice the line here.
If I zoom in on the end is not quite touching the spline.
So if I get in real close, you can see the gap.
So we just go up here and we just go to Extend.
I'm not going to select a boundary edge this time.
In the newer versions of AutoCAD,
I can just click on that line and it extends.
If I come out a bit now, roll back on the wheel
and pan across a little bit.
You'll see here, I also need to extend again.
So I just click on this end
and extend and press Enter to finish.
When I zoom out
you can see our deckings all nice and neatly lining in
with that circular bit of concrete hard standing.
So as you can see, Trim and Extend,
extremely useful in your AutoCAD drawings.
