Interlocking
Hearts in Illustrator CS By Sara

Drawing the heart
Step 1. With Valentine's Day just around the corner I
thought hearts would be appropriate. First we'll draw the perfect heart in a few
steps, then we will see how to interlock two hearts. To begin, start a new
document.
- Turn on the Rulers (View > Rulers). Right click on the
ruler to set the unit of measurement and choose pixels. I chose pixels since
we are working for the web.
- Now go to Edit > Preferences > Guides & Grid
and set Gridline Every to 36 px and
Subdivisions to 1.
- Turn on the Grid (View > Grid) to use as a visual aid.
- Go to View > Snap to Grid so the tools will snap to
the grid. This will make it easier to be accurate while we draw the heart.
- My colors are set to the default white fill and black stroke.
Step 2. Select the ellipse tool from the tool box. Place the
cursor on an intersection point of the grid. Hold the option key (Mac) or alt
key (Windows) and click once to open the ellipse options. Holding the opt/alt
key will make the circle draw from the center; the center of the circle will be
exactly where the cursor was when you opened the ellipse tool options.
Enter 288 for both width and height, then click OK. Because we chose pixels
for unit of measurement, Illustrator will use pixels automatically. A 288 px by
288 px circle will appear on the page. You now have four anchor points joining
curved line segments.
If you want to see the center point you will have to turn it on. To do this,
go to Window > Attributes to open the Attributes palette,
and click either the Show Center button or the Don't Show Center
button . This is a matter of preference.

Step 3. In the pen tool flyout, choose the convert point
tool. Right now you have four curved points. We need a couple corner points
instead to make the circle into a heart.

Step 4. Click the bottom anchor point of the circle once
with the convert point tool to covert it to a corner point. If you have Smart
Guides enabled, when you hover the cursor over the point a small label will
appear that indicates it is an anchor point. Smart Guides are a lot of help but
they can also be annoying so you can turn them off and on at anytime using
View > Smart Guides.

Step 5. Change to the Direct Selection tool (A) and click on
the top anchor point and drag it down two squares. It might be easier if you
have the fill turned off. To do this, make sure fill is the active square in the
color boxes on the toolbox (that is, the fill square is on top), and click the
none button under the color boxes. It's a white square with a red line across
it.

The anchor point has two handles extending from it. Moving these handles will
adjust the curve between the the top and side anchor points. (The two vertical
handles extending upward in the screenshot are from the side anchor points.)

Step 6. Hold the option key (Mac) or alt key (Win) and grab
the right handle of the top anchor point and drag it upward three squares.
Holding the option or alt key lets you turn this anchor point into a corner
point with two handles that move independently of each other. Because
Snap to Grid is on it will "snap" to the intersection of the
grid.

Step 7. Use the Direct Selection tool (A) to drag the left
handle up three squares. You should have something similar to this at this
point.

Step 8. Click the left anchor point with the direct
selection tool so you can see the handles extending up and down from the point.

Step 9. Click the bottom handle of the left anchor point and
drag it right toward the heart one square to reshape the bottom of the
heart.
Step 10. Click the right anchor point with the Direct
Selection tool to show both anchor points. Click the bottom handle of the right
anchor point and drag it left toward the heart one square. Save the file.
Step 11. Go to Window > Stroke to open
the Stroke palette. Change the stroke to 15. Choose another stroke color if you
wish. Now go to Object > Path > Outline Stroke.

Interlocking the hearts
Step 12. Duplicate the heart by holding the option key on
the mac or alt key in windows and dragging away from the heart, then release the
mouse to drop the new heart on the artboard. Now you should have two hearts.
Turn off Snap to Grid (View > Snap to Grid) so you can move
the hearts freely without the snap. Position them so they overlap, and give the
second heart a different fill color. Notice that before we changed the color of
the heart by changing the stroke color, and this time I told you to change the
fill color. That's because when we outlined the stroke, we turned the heart into
an object.

Step 13. Click one heart, hold the shift key and click on
the second heart so both are selected and open the Pathfinder palette
(Window > Pathfinder). Click the Divide
button. This will make separate pieces of the hearts wherever they overlap.

Step 14. Ungroup the hearts (Object >
Ungroup).
Step 15. Use the Selection Tool (V) to select the part of
the top heart you want to go behind the back one. I decided to link them at the
bottom, so I selected the small area of the pink heart where it overlaps the red
one.
Step 16. Change the color of the selected object's fill to
the same color as the back heart. Now it looks like the hearts are interlocking.
We could stop now, but we won't!

Step 17. Click one part of the back heart, hold the shift
key, and click the other two heart pieces that are the same color. You will have
three pieces selected, two large heart pieces and the third is the small piece
that we changed the color of before. Group them (Object >
Group). Select the three parts of the second heart and group them as
well.

Step 18. Click once on the back heart to select it. Go to
Effect > Stylize > Inner Glow so we can add some shading
to give it some dimension. Change the mode to Multiply and the color to a darker
shade of your heart color. I left the opacity at 75%, and set the Blur to 6
pixels. Make sure you check the Preview box so you can see the effect on the
heart while you experiment with the settings. Click OK when finished to apply
the glow.

Step 19. Click once on the second heart to select it (or
techincally its group) and apply an Inner Glow with the same settings, except
change the color to a darker shade of the second heart's color.

Variations
On step 11, make the stroke thicker. This one is 30 pt. Go to Object
> Path > Outline Stroke and then continue with steps 12 through
17. On step 18, here are some alternate settings for the Inner Glow. Follow step
19 to finish.
