Ai Part VI: Creating Symmetrical Curves

This is the sixth tutorial in the Illustrator Beginner’s series. We’ve already covered placing sketches, using the Pen tool, tracing sketches with the Pen tool, making symmetrical vector files and using the Ellipse tool. This lesson covers creating symmetrical curves by making the smiling mouth.
Here’s my sketch. You can either work on the same layer as your other shapes or create a new one to work on for the mouth. If you want a refresher on using layers, you can refer to the first tutorial.
Start by drawing one half of the smile using the Pen tool. Start your first point at the corner of the mouth and make the second one near the middle of the mouth. Hold down the Shift key while making the line curve. If you need a refresher on the Pen tool, check it out here.
The reason for holding down the Shift key is it makes your curved line end pointing in a straight line or parallel to your page edge (instead of being angled up or down).
Next, draw the crescent shape for the cheek. Start by making the top curved line with the Pen tool, then click off of the line. Remember you can hold down the Command/Control key to quickly switch between the Pen and the Selection tools. Now, start drawing again by hovering your mouse over the last point you made. When you see the slash next to the tooltip, click on the point. Then complete the shape by hovering over the original point until you see the circle. Click on the point and pull out your curve.
Note: If you try to restart your curve on the first point you made, you’ll probably have trouble with trying to make the right shape (you end up with a distorted blob). If this happens to you, undo the last line (Command/Control Z) and start at the opposite point instead.
Now, select the two parts of the mouth to make a copy. To select multiple objects, Shift click on the second object or draw a box around all the objects you want to select with the Selection tool. Now that your objects are selected, hold down the Option and Shift keys while dragging the objects to the right. You’ll want to press the Shift key after you start dragging, otherwise you’ll deselect the shapes.
With your copied half mouth selected, double click on the Reflect tool.
A dialogue box pops up. Select Vertical and click OK.
Your mouth should have flipped. You may need to move it around to get it to line up with your sketch.
Now connect the two mouth halves with the Pen Tool.
Open up your Stroke palette. Go to Window > Stroke.
The Stroke palette pops up and I set my stroke to 2 pt. This will thicken up your line a little.
Now, let’s make your line into a closed shape. Select just the mouth and not the cheeks. Go to Object > Path > Outline Stroke. You’ll notice your stroked line is now a closed shape. I usually don’t do this step until the very end, so I can change the stroke weight if I want.
You can also outline your stroke by using the Flatten Transparency. Flatten Transparency will also convert dashed lines and brush effects which the Outline Stroke doesn’t do. Go to Object > Flatten Transparency to use it. Move the slider to 100% Vector.
Finally, select the cheeks and the smile and use the Add to shape area from the Pathfinder palette. Again, I probably wouldn’t do this step until the end. Just in case I wanted to change something, but I figured it was good to show for the tutorial.
Here’s my final mouth. I was originally going to do the stem in this tutorial too, but this one ran long. So, it will get done in the next one.

Ai Part V: Using the Ellipse Tool

This is the fifth tutorial in the Illustrator Beginner’s series. We’ve already covered placing sketches, using the Pen tool, tracing sketches with the Pen tool and making symmetrical vector files. This lesson covers using the Ellipse tool to make eyes.
Here’s my sketch. You can either work on the same layer as the leaf shape or create a new one to work on for the eyes. If you want a refresher on using layers, you can refer to the first tutorial.
Select the Ellipse tool from the Toolbar.
Next, draw an ellipse. Click on the starting point of your oval and slowly pull your mouse down until your ellipse is about the same size and shape as your sketch.
Many times, I’ll just use the oval as is, but let’s make it a little more difficult by using the Direct Section tool to adjust the curves. You may want to zoom in on your oval to adjust it. Z on your keyboard will bring up the Zoom tool. If you click on the artboard with the Zoom tool, it will zoom in a set amount. This is kind of tedious, so I usually use it by clicking and dragging a box around the area I want to zoom in on. I think this is a much easier way to use it. To zoom out, hold down the Option/Alt key. You’ll notice the tooltip changes from zoom + to zoom -. Again, this will only zoom you out in increments. I like to use View > Fit in Window or Command/Control 0.
Alright, back to the Direct Select tool… I click on the line of the oval with the Direct Selection tool. The line lights up and I can see all the anchor points and handles. I start by clicking on the left middle anchor point and pulling it down a little. This makes my eyeball a little more bottom heavy and egg shaped. Next I grab the top left handle of the top anchor point and move it in or closer toward the anchor. If I hold down Shift while I’m moving it, it will only move in one direction. Then, I do the same with the right handle.
For a more precise way to move anchor points and handles, you can use the arrow keys on your keyboard. Select the anchor point or handle you want to move and click on the arrow key to move it in an incremental step.
You can adjust the distance the point moves by changing your settings. Go to File > Preferences > General. A dialogue box pops up and the first box is keyboard increments.
Next, draw the pupil with the Ellipse tool. Holding down the Shift key while you draw an oval will make it a perfect circle.
Now to flip the eye you just drew, so you can have a symmetrical second eye. Select both the eyeball and the pupil with the Selection tool. Next drag them to the right like you were going to move them, but hold down the Option/Alt key and the Shift key. You’ll want to press the Shift key after you start dragging, otherwise you’ll deselect the shapes. Holding down the Option key will make a copy of the shapes while you drag them and holding down the Shift key will make sure that you only move the shapes left and right and not up and down.
To flip them, double click on the Reflect tool while they are selected.
A dialogue box pops up. Choose Vertical and click OK.
You’ll probably have to move the eye a little after it flips to get it in position. Hold down the Shift key when you move them like before, so the eye only moves in one direction. Or you can use the arrow keys to nudge it over. Here are the eyes with the leaf shape. Next, it is on to the mouth and the stem.

Ai Part IV: Symmetrical Objects

This is the fourth tutroial in the Illustrator Beginner’s series. We’ve already covered placing sketches, using the Pen tool and tracing sketches with the Pen tool. This lesson is about making symmetrical vector files. The best way to make sure your file is symmetrical is to draw half of it and flip it.
In the last tutorial, I traced over my placed sketch with the Pen Tool. Since the stem isn’t symmetrical, I’ll draw that later.
Next, I want to use the Reflect Tool. It usually hides under the Rotate Tool, so click and hold the Rotate Tool to see it.
With your leaf half selected, double click on the Reflect Tool. A dialogue box will pop up. Set the Axis to Vertical and click copy.
This will make a copy of your leaf facing the opposite way.
Next, you’ll want to make sure your Smart Guides are on. Go to View > Smart Guides or use the keyboard shortcut Command/Control U. If you’d like to know more about Smart Guides you can see a brief tutorial about it here.
With your Smart Guides on, you can roll over your lines and they light up and say things like path or anchor. Now, you’ll need to line up the two edges of your leaf halves. Roll over straight edge of one of your leaf halves. When it says path, click on the line and drag it towards the other half’s straight edge. You’ll want to hold down Shift while dragging the half. Holding down Shift constrains your object to moving on only one axis. In this case, you want your object to move right and left, but not up and down. When the leaf half line that you’re dragging hits the other leaf half’s line, the line will light up and it will say intersect. That means they are lined up and you can stop dragging.
If for some reason your two halves aren’t top aligned, you can use the Align palette to align them at the top. Open the Align palette by going to Window > Align.
Now that your leaf halves are lined up, you’ll need to join them.
You can use the Pathfinder palette to join them. If you don’t have your pathfinder palette open, go to Window > Pathfinder. Select both halves using the Selection tool in the Toolbar. To select a second object, hold down Shift and click on the second object.
With the two halves selected, use the Add to shape area on the palette. It is the first button on the top row. Click Expand to finish joining the objects. Now, you have a symmetrical object.
As with any time your working in Illustrator, if you make a mistake use the Undo. Go to Edit > Undo or Command/Control Z.
Since your leaf shape is complete, we’ll move onto the eyes in the next tutorial.

Ai Part III : Tracing with the Pen Tool

This is the third part in my Adobe Illustrator Beginner’s series. This tutorial is about tracing over your pencil sketches with the Pen tool. The first part of this series was about getting your sketches into Illustrator and the second part was about using the Pen tool. If you missed the either part, you can check out the first one here and the second one here.
Here’s my placed sketch.
Select the Pen Tool and the color you want to draw in from the Toolbar. I like to draw in a bright color like red, so I can see the lines over my sketch.
Start by clicking on the bottom of the leaf in the middle. Next, click on the top in the middle. Hold down the Shift key when you click. Holding down the Shift key will make your line straight.
Now, you want your line to curve to follow the shape of the leaf. Make your next point, at the end of the curve, but don’t release the mouse button. Instead, slowly move your mouse down. Notice it is making a curved line. When you get the curve correct release the mouse button.
After making a curved line, you’ll want to click off your line to avoid the recipricol curve like in the last tutorial. Hold down the Command/Control key to get either the Direct Select or the Selection tool and click off the line on the empty artboard. Then, release the Command/Control key and continue drawing with the Pen tool.
Now you want to continue drawing with your line. With the Pen tool selected, hover your mouse over the end of the line. A small black slash mark will appear next to pen tool tip (or the part where your pen meets paper). This means that you are over the end point of the line. Click on it. If you miss just undo. Go to Edit > Undo or Command/Control Z.
Next, click on the next point you want your line to continue to. This line is a straight line, so you won’t have to click off of it to draw the next one.
Continue following the contour of the leaf by making the line curve and go straight. When you come to the end, you’ll want close the shape. If you remember from the last lesson, to close a shape hover over the first point you made. You’ll know you’re over the point when a small circle appears next to your pen tool, then click on the point. Your line or path is closed.
You have just drawn half the leaf shape. The next lesson will show you how to flip the shape and join it, so you have a symmetrical object.

Ai Part II: Pen Tool Basics

This is the second part in my Adobe Illustrator Beginner’s series. This tutorial is about drawing with the Pen tool. The Pen tool is Illustrator’s workhorse. It takes time to learn how to use, but is one of the key drawing tools in Illustrator. Once you master the pen tool you will be able to use it in projects you send to online printing services. The best way to learn the Pen Tool is to trace over sketches. Before we get to that, this is a basic overview of the pen tool.
Before you start using the Pen tool, you’ll want to set your colors. Illustrator has two color options the Fill color (the color inside a shape) and the Stroke color (or the outline color). I like to draw with a Stroke color and no Fill color. You can change the colors of the Fill and Stroke on the Toolbar using the Swatch palette. To get the Swatch palette, go to Window > Swatches.
After your Swatch palette is open, click on the color you want. I chose black. Notice you are editing either the Stroke or the Fill based on which one is on top on the Toolbar. To edit the other one , click on the one underneath (either the fill or the stroke). It will move to the front, then click on a swatch in the Swatch palette for that one. The white swatch with the red line through it is no color.
Now, on to the Pen tool. This is the pen tool on the Toolbar.
The pen tool works by placing anchor points down and drawing lines in between them. Click on the artboard (the area of the file you draw on) with the pen tool selected. You’ll notice a point appears.
Now click on another place on the artboard. Another point appears and a line is drawn between the two points.
Next, make a third point.
Finally, conect the third point to the first. To do this you’ll need to click on the original point. Hover your tool tip or mouse pointer over the original point. You’ll know you’re over the point when a small circle appears next to your pen tool, then click on the point. Your line or path is closed.
Congratulations, you have just made a shape with the Pen tool. Look out Picasso! You’ve created a lopsided triangle.
Let’s make a curved line now. Make your first point. Then, make your second point, but don’t release the mouse. Instead, drag the mouse downward or upward slowly. You’ll notice the line starts to curve. When you get the curve you want, release the mouse button.
Now make another point. You’ll notice Illustrator makes a recipricol curve.
Let’s say you aren’t happy with that curve. You can go to Edit > Undo Pen to delete the last step. Or maybe you change your mind, go to Edit > Redo Pen and it is back.
That curve still doesn’y look right to you, so let’s manually adjust it. Go to Toolbar and select the Direct Selection tool (it’s the white arrow).
You’ll notice that whenever you make a curved line it has a little blue handle (or other layer color) that comes off of it. You can use this to adjust the curve. Click and grab the point at the end of the handle and move your mouse around to adjust the curve. Once you get the curve right release the mouse button.
After all that, you still hate your curved line, so let’s delete it. Select the Selection tool, the black arrow on the Toolbar and click on your curved line. Then hit Delete on the keyboard. It should be gone. You can always Undo it if you want it back.
To make your life easier, I have a list of keyboard shortcuts for the Toolbar tools here.
Finally, let’s make a line that curves then goes straight. Make a curved line like you did before.
Instead of making another point, click on the Direct Selection or the Selection tool and deselect your line. To deselect your line, just click on a blank spot on the artboard using one of the Selection tools.
A good trick to switching between the Pen tool and your last used Selection tool is to hold down the Command (Apple) key on a Mac or the Control key on a PC. Try it out. Select the Pen tool on the Toolbar. Now hold down the Command/Control key. You’ll notice the tool tip change from the Pen to the Selection tool.
Back to your curved line. To restart drawing on the same line, hover your mouse over the end point like you did when you were closing a shape or path. This time instead of a circle beside the Pen tool tip, you’ll see a slash mark. This means you’re over the point. Click on it and then make your next point and your line will continue. You should have a line that curves then goes straight.
Well, that’s it for my Pen tool basics. There’s more to the Pen tool, but that’s enough to get you started. The next tutorial will be applying all of this to the leaf sketch from the first tutorial in the beginner’s series.
