- [Instructor] In this movie,
I'd like to show you some techniques
for creating logos that radiate from a center point.
In my first example,
I want to use a live effect called transform.
So effect, distort and transform, transform.
This is a very powerful dialog box.
We can scale, move, rotate,
and make multiple copies.
In this instance,
I'd like to scale my selected hexagon to 92%.
Let's turn on the preview.
It's scaling from its center point.
I also would like to rotate it,
an angle of 80 degrees.
I'll press the tab key to update the preview.
And then I would like eight copies.
Each of those copies is at 92% of the previous instance,
and each one is rotated 80 degrees
from the previous instance.
In a similar vein here,
I'm going to once again,
come to my distort and transform.
This time, I want to increase the scale to 110%,
and the angle will be 15 degrees.
But I want the rotation to take place
from the bottom left hand corner.
Let's turn on the preview
and I would like three copies.
Now in addition,
I need to change the transparency,
so with my one object selected,
and when you make a transformation like this,
they are all derived from this one object,
and it's not until you expand that object
that you'll have access to the individual shapes.
But for now, I want to keep it as a live effect.
I'll come to my appearance panel
and click on the opacity and then change that to multiply,
and then we get that really nice interior shape effect
created by the overlapping elements.
I'll then come back to my effects.
I could either go to the effect menu
or since I'm on the appearance panel,
I can come to the effects drop down,
and distort and transform, twist,
and I'll twist this through 60 degrees.
Now in this example,
you might think that we could use the same approach,
and in fact, we can't,
and the reason is that these transformations all take place
around another object,
and that other object is the circle,
which is a guide circle in the center.
A shortcoming of the transform dialog box
is you can only transform elements around themselves.
You can't rotate them or transform them
around another object.
So I'm going to begin by drawing myself a small circle.
And then I'll convert this to a guide,
Command or Control + Five.
And I think I actually want to slightly move that down
so it's somewhat overlapping.
With my petal selected,
I'll now come and press R
to choose my rotate tool,
and mouse over the center of the circle
and Alt + Click.
Now in this case, I want 18 petals.
So that's 360 divided by 18,
which is at an angle of 20 degrees.
I'll copy,
and I already have the opacity set to multiply,
so we get this overlapping effect right away.
Command or Control + D
to repeat that transformation
until I get back to the top.
Now in this example,
I want to create this sunflower effect,
and once again, we need to make the transformation
around another object.
That object being the center circle,
so I'll draw myself a circle
and press Command or Control + Five
to convert it to a guide.
Now I'll come and choose my line tool.
Let's deselect,
and then from the top of the circle,
I'll draw myself a line,
and I'm going to give that a stroke.
Now I want the strokes to be dotted.
So I need to come to my stroke property
and check dashed line.
Now the key here is to make the dash value zero.
The gap determines the spacing between the dots,
and the weight determines the size of those dots.
I said the key was to set the dash to zero,
but that's only half the story
because we also have to check rounded cap.
So when I've done that,
and I've chosen the appropriate size of dot,
I'm going to go for a weight of four points,
let me just zoom in a little bit here.
And then I'll choose my rotate tool,
Alt + Click on the center point.
Now once again, I want 18 copies.
That's at an angle of 20 degrees.
Copy, Command or Control + D
to repeat that transformation.
Now I'm going to come back and select my original line,
return to my rotate tool,
and rotate this through 10 degrees,
making a copy.
And I would just like to shorten this line,
so with my direct selection tool,
I'm going to pull it down to about 2/3 of the height.
Now back to my rotate tool,
and once again, I'll rotate around the center point,
but I need to make sure I have the whole of that line
and not just an individual anchor point selected.
And we'll set the rotation angle back
to 20 degrees and copy.
Command or Control + D.
Now I need to select all of these lines
and group them together.
Then I'm going to come to the effects menu
and it has to be twist that we're after,
so I'll choose twist
and I want to use an angle of 135 degrees,
but when we do that,
we see that the whole effect goes haywire.
I'll click okay to that,
and now come to my appearance panel.
And the solution here is I need to change the position
of the twist effect on the appearance panel
so that it affects the contents of the group.
So if I drag this down underneath the word contents,
then we get the result that we're after.
So those are some of the considerations
and some techniques for creating logo symbols
that radiate from a center point.
