- [Instructor] In this movie, we'll duplicate
the two lines that we've drawn so far,
in order to create these ridges
along what will ultimately be the top of the factory.
And along the way,
I'll show you a few different things
that you can do with the black and white arrow tools.
So I'll go ahead and switch over to these lines.
You can see that they're both selected,
but if you're working along
and they're not selected for you,
then you can just partially marquee them
with the black arrow tool.
And because I'm working with the black arrow,
no matter what, I'm going to select the entire objects.
Now what I want to do is move these lines,
and you can do that by dragging on either one of them,
like so, and so of course if you just drag them
and then drop them into a new place,
that's where they're going to land.
There's other ways to work, however.
Let's say for example, that you want to duplicate the paths.
In that case, instead of just dragging and dropping,
you would drag them,
and then you would press and hold the Alt key,
or the Option key on the Mac,
and notice at that point, I get a double arrowhead cursor,
which tells me that I'm going to create a duplicate.
So again, you go ahead and press the Alt key
or the Option key on the Mac after you begin dragging,
and then hold it until after you release,
in order to duplicate those paths' outlines, like so.
I want a little more control, though,
I want to go ahead and just move these lines horizontally,
so I will press Control-Z, or Command-Z on the Mac,
to once again undo that move.
And then this time, as I drag,
I'll press and hold the Shift key,
which will constrain the angle of my drag
to some multiple of 45 degrees.
So that way, I can drag directly up, I can drag diagonally,
or I can drag horizontally, like, so.
But what I really want to do
is duplicate these lines horizontally,
and I want them to snap into alignment.
So I will once again press Control-Z, Command-Z on a Mac,
and this time, I will drag by this anchor point right there,
so again,
your bounding box needs to be off for this to work,
otherwise, you're going to scale your lines,
which is not what we want.
So go ahead and drag by this lower anchor point,
while pressing the Shift key, until you see a snap,
right there at that location,
as indicated by that white arrowhead cursor,
and then you also want to press the Alt key,
or the Option key on the Mac,
at which point you're going to get a double white arrowhead,
telling you that you're going to snap a duplicate into place.
So again, I've got the Shift and Alt keys
down here on the PC,
that would be Shift and Option on the Mac.
Hold those keys down, release your mouse button,
and then release the keys.
All right, now I want to create yet another duplicate,
and so, I could of course replay that operation,
but there's an easier way to work,
and that's to go up to the Object menu,
choose Transform, and then choose this very first command
at the top of the sub-menu, Transform Again.
Or, better yet, use the keyboard shortcut
that makes a heck of a lot more sense,
which is Control-D, or Command-D on the Mac,
the D being for duplicate.
And so essentially,
you're going to replay your last duplication.
Again, Control-D, or Command-D on the Mac will do.
All right, now I want to draw a vertical line
going downward from this point right here.
So I'll go ahead and switch to my line segment tool,
which again, you can get
by pressing the Backslash key if you like.
And I want the line to start at this point right there,
but if you get this behavior when you drag the line,
that is to say you end up moving that selected point,
then just undo that movement,
and then go up to the Select menu,
and choose Deselect once again,
or press Control-Shift-A or Command-Shift-A on the Mac.
And now, you should be able to drag a line down, like so.
I want this line to be absolutely vertical,
so I'm going to press and hold the Shift key as I drag.
And I'm looking for a distance value
of about 300 points, let's say,
so I've got a devalue of 300 points
in that heads-up display, I have an angle of 270 degrees,
because I'm dragging down with the Shift key down as well,
and then, I'll go ahead and release the mouse button,
and then release the Shift key.
All right, now what we want to do
is extend this line right there,
so it aligns to the bottom of the line we just drew,
and you can do that by switching to the white arrow tool,
which you can get either by selecting
the second arrow up here at the top of the toolbox,
and don't worry if you don't see a tail
on your white arrow icon,
the tool still works the same as it ever has.
Or you can just press the A key, for arrow.
Then, go ahead and click
on this so-called anchor point right there,
which is located at the bottom of this right hand line.
And notice, if you will, if you look closely,
that the selected point is now filled in,
it happens to be red, because we're working on a red layer,
and the top point is hollow,
indicating that it is not selected.
So now, if I go ahead and drag this point down like so,
and I press the Shift key,
just to make sure that I'm constraining
the angle of my drag to exactly vertical,
if you have smart guides turned on,
you're going to see these intersecting lines
that are telling you that you have a match.
So you want to make sure you're seeing that bottom,
in my case, pink line.
It might be green as well,
depending on what version of the program you're working on.
But you want to see that intersection,
at which point you can go ahead and release,
knowing that these two points are absolutely aligned.
All right, finally what I want to do
is move these ridges downward,
and I'm going to do so by marqueeing
all of these top anchor points.
So notice, whenever you drag
in an empty area of your document,
you're going to create a dotted marquee,
and then anything that falls inside that marquee
is going to become selected, because after all,
unlike the black arrow tool,
which always selects entire path outlines,
the white arrow tool is going to allow you
just to select those points that fall inside the marquee.
So make sure that you draw the marquee
around all the top points, like so.
And then, go ahead and drag any one of them downward,
while pressing the Shift key,
just to make sure that the angle of your drag
is exactly vertical,
until your cursor snaps into alignment
with that horizontal guideline,
and you'll know you have a snap,
because for one thing, you can feel it,
and then for another,
your cursor will change to a white arrowhead.
At which point, go ahead and release the mouse button,
and then, release the Shift key.
And that is how you both move and duplicate
entire path outlines, as well as independent anchor points,
here inside Illustrator.
