- [Voiceover] In this movie, we're going to,
expand these green shapes in order to create this white one.
And we're gonna do so using a special scaling function,
known as offset path.
So, I'll go ahead and switch over to my base star flower.
And just to demonstrate why the scale tool,
is not the solution is not the solution in this case,
I'll go ahead and select one of these green shapes.
And then I'll go up to the control panel,
and click the Select Similar Objects icon,
in order to select all of these guys.
And, if for some reason that doesn't work,
then you can click this down-pointing arrowhead,
and choose All or Fill Color.
Either one's gonna be fine.
Alright, now that I've selected all of the green paths,
I'm gonna go ahead and duplicate them onto this back layer.
So, you know what?
I'm just gonna go ahead and unlock that layer,
pull open the layer and lock the rectangle instead, like so.
Alright, now to duplicate these paths,
I'll just go ahead and Alt or Option drag that red square,
until it becomes an orange square on the back layer like so.
And you can see, now we've got a bunch of green shapes.
I'm gonna make 'em light so we can see the difference,
by clicking on the first color swatch up here,
in the control panel and changing it to white.
That's not going to make any difference on screen right now,
because the white shapes are covered up,
with the green ones.
Well, we'll be able to see things in just a moment,
after, I select a Scale Tool from that same fly-out menu,
that contains the Shear Tool.
Or, you can just go ahead and press the S key.
Alright now, just to make sure I'm doing things properly,
I'll twirl this back layer closed,
and I'll turn the guises layer back on,
so I can see my center guise right there. And,
I'll Alt or Option click at the intersection of those two
center guides to bring up the Scale dialogue box.
And then I'll start with the uniform value of 100 percent.
And I'll press Shift, Up, Arrow in order to,
increase it to 110 percent. And you can see that,
this does not give me the right effect at all.
We're getting this kind of tapering right here,
in the corners. And then the shapes expand,
at the tips of each one of the five petals.
If what you really wanna do is,
expand the path outlines uniformly,
then you need to switch to the Offset Paths command.
And, let me show you what that looks like.
I'll go ahead and cancel out.
And, I'll press the backspace key,
or the delete key on the Mac, in order to get rid,
of those duplicate paths. And,
I'll press the V key to switch back to my black arrow tool,
click on one of the green paths once again,
and then click on a Select Similar Objects icon,
up here in the Control Panel, to select all five of 'em.
Now you wanna go to the Object menu, choose Path,
and choose this guy right here, Offset Path.
So, it's a hard command to find,
and it's not arranged with the other,
Transformation functions.
And that's because, as the logic goes,
it's more of a Stroke function. So notice we have,
Outline Stroke, which does just that.
It takes Stroked outlines,
and it converts them to Field Paths.
The other option, though,
is to build a kind of Stroke on the fly,
using the Offset Path command. So,
go ahead and choose that command,
and then enter an Offset value. And, by default,
you're gonna see an Offset of 10.
Go ahead and turn on the Preview check box and you'll see,
how the Path builds outward, 10 points, like so.
If you wanted it to go inward instead, you could enter,
a negative value such as negative 10,
and that'll move the edges inward.
The value I'm looking for, however, is 24.
So, I'll just enter an Offset value of 24 points.
We don't care about the Joins, by the way.
They're all Miter Joins as things stand.
You could round them, if you want to,
by selecting Rounds. And notice that goes ahead and rounds,
all of those corners. But, Miters are gonna work out,
just fine. Don't need to worry about the Miter limit,
because we're not getting any beveling. So,
I'll just go ahead and click, OK, in order to,
apply that effect. And what's just happened there,
by the way, if I press the backspace key,
or the delete key on the Mac,
in order to get rid of the new shapes.
You can see that the old shapes are still intact.
And that's because the Offset Path command,
always scales a duplicate. Alright, I'll go ahead,
and undo the deletion of that duplicate.
And, I'll change the Fill color to white, like so.
And now, I'll go ahead and move these guys,
onto the back layer, by dragging this little red square,
on the right side of the Layers panel,
down to the back layer. At which point,
it'll turn gold and you'll see those white shapes,
moving behind the green ones. Alright,
we still have some holes here and there.
And we have too many intersecting paths. So,
let's clean things up by bringing back up,
the Pathfinder Panel, which I can get,
by clicking on this Pathfinder icon right there.
And then, I'll unite everything by clicking on,
the very first icon, in the first row.
And that's gonna result, by the way, in a compound path,
as we could see in the far, left side of the control panel.
Alright, I'm gonna go ahead and hide the Pathfinder panel.
And, I will dissolve the Compound Path because,
after all, I don't wanna see any of these holes;
by going up to the Object menu, choosing Compound Path,
and then choosing release.
And then finally, what you wanna do is just Shift, Click,
on this outside Path to deselect it.
And press the backspace key or the delete key on the Mac,
to get rid of all the internal Paths. Alright,
now I'm gonna hide the Guise Layer,
once again, because it's distracting.
And, I'll select this, outer-most Path,
and then I'll go up to the Effect menu,
choose Stylize, and choose Drop Shadow,
to bring up the Drop Shadow dialogue box.
These are the default settings by the way.
Mode set to Multiply, it doesn't really matter.
Capacity is set to 75 percent.
Both X and Y Offset are seven points,
and the Blur is five points. That works out just fine,
for me. So, I'll just turn on the Preview check box,
in order to see that shadow form in the background.
And then I'll click OK to accept that effect.
And I'll click off my Paths in order to deselect them.
And that folks, is how you uniformly,
scale a shape. Either to make it smaller,
with a negative value, or larger with a positive value,
using the Offset Path command,
here, inside Illustrator.
