- [Instructor] We're staying in our Office Layout.dwg file.
And we're going to take a look
at the Break and Join commands available to us in AutoCAD.
Now we've worked up to this point
with our Office Layout and somebody
in their wisdom has decided to move the door opening
which is at the moment bottom right.
We need to mirror it to the other side of the office
and we need to lose this desk here.
So after all that work of mirroring the desk
to make sure it was accessible, the company have decided
that we don't need that desk there anymore,
but we do need to move the door.
Now we're going to utilize a few commands here
but we're also going to utilize Break and Join.
Now you'll notice that the walls are hatched
and there's a hatch pattern there.
So if you just touch on the hatch pattern,
can you see it highlights like that?
Just click on it, like so, and it goes blue.
What I'd like you to do is just click
on the grip in the middle, like so,
just click on it and move the hatch away from the office.
So if you need to zoom out a bit,
maybe pop it over here to the left.
As soon as you do that,
the hatch pattern obviously is highlighted
over on the left-hand side.
Just hit Escape a couple of times to deselect it.
Don't worry about it at the moment, we'll rectify the hatch
once we've done the breaking and the joining.
Now, we need to zoom in again a bit,
and we need to get rid of this plants, this chair,
this desk, and this computer.
So just click on each of them to select them,
right click and on the shortcut menu, click on Erase.
So that clears the space for our little door here
to come over to this side.
Now, we're going to mirror the door.
Now there's four parts of the door.
There's the arc, the line there,
and there's two little lines, one and two,
that form the opening as well.
So make sure you've selected all four objects.
We're then going to go up to the Mirror command
on the Modify panel, click on it
and come back into the drawing area.
Now the first point of the mirror line is going to be a
really super-duper little object snap.
Hold down the Shift key on the keyboard and right click.
That brings up your snap overrides.
Select Mid Between 2 Points.
And we're going to select this outside corner here, left click,
and go over to this outside corner here, left click.
That gives us the exact midpoint of the wall, you'll notice.
Can you see that?
So now the door is mirroring to the left hand side.
So what we're going to do is we're going to bring that upwards.
So we've got the first mirror line point,
just come up the polar tracking line,
anywhere on the polar tracking line, just left click.
Erase source objects?
Yes, please.
Click on Yes.
So what you'll find now is you've got a gap
where the door was, and you've also got lines here
that we need to break.
So we need to join the gap here and break over here.
Let's zoom in on the gap here and use the Join command.
That's on the Modify panel,
so we click on the little flyout next to Modify
and pin it open, like so.
And you'll see, we've got various break commands
and there's Join right there.
Looks like two little arrows kind of butting heads.
So click on Join, and you're going to select this line
and this line, press Enter to confirm.
That joins the lines together and forms one line,
as you can see.
Just hit Escape to deselect that line.
Join again on the Modify panel,
and now I'm going to click here, one there, one there,
press Enter to confirm, joins that one as well.
You can do that with arcs too
but they have to be colinear,
following the same linear path.
I'm just going to pan across now to our doorway.
Zoom in on our doorway a little bit here
and we need to do some breaking.
Now we've got two choices.
I've got, Break here,
which breaks the selected object between two points
or I've also got Break at Point.
We're going to do one of each.
So let's do Break at Point first.
So I select Break at Point
and click on it and select object.
I'm going to select this line here.
And the break point is going to be there.
So I've broken it into that line and also that line there,
but I need another break here for the door opening.
So I'll just hit Escape to deselect.
I go to Break at Point again
and I select this line, like so,
and then I click on that break point there.
So now I've got one, and two, and three, three lines.
I need the middle segment here,
so I click on it, right click and Erase, that one's gone.
Let's use Break between two points now, which is this one.
So there's Break there.
Breaks the selected object between two points.
Click on that one, come into the drawing area
and we're going to select the lower line.
Now it assumes that where I'm selecting the lower line,
can you see?
Is the first break point.
So I need to right click
and go First point and select that point there.
Then it'll prompt me for the second break point,
which is that point there.
Click again, and that one breaks and leaves a gap.
So it's actually a little bit quicker to use that one
rather than Break at Point, that one there.
But they're both cool break commands
that allow me to tidy up and modify my drawing.
So I'm now just going to double click on the wheel
to zoom extents, like so,
and we need to put our hatch pattern back in place.
Very quick and easy.
We're on the walls line already.
We just need to go to Hatch here on the Draw panel.
So click on the flyout there and select Hatch.
We don't need to worry about any of the Hatch settings.
We just select Match Properties up here.
So we click on Match Properties, like so,
and we select this hatch pattern here, like that,
and we just come in here,
pick an internal point inside the walls,
click again, and press Enter.
And you can see that sorted that out
with the new door there, it's all around the new door.
This hatch pattern you can just select
and you might get prompted
about nonassociative hatch boundary grips,
don't worry about that.
You just need to right click
and Erase the old hatch pattern.
Double click on the wheel to zoom extents,
maybe roll back on the wheel one notch,
and there's our finished door move
with Break and Join in AutoCAD.
