00:00:33  Notice that my pen cursor, once again, has an asterisk

00:00:36  to show me that I'm about to create a new path outline.

00:00:38  I'm going to do so by clicking and dragging.

00:00:42  So the point at which you click,

00:00:44  that determines the location of the smooth point,

00:00:46  and as you drag, you're going to draw forth control handles.

00:00:49  One, under your cursor,

00:00:51  and the other, opposite the cursor like so.

00:00:55  And now notice that my rubber band preview is curving

00:00:58  to show me that I'm going to create a curving segment,

00:01:01  but it's not entirely accurate.

00:01:03  What we're seeing is a preview of what would happen

00:01:05  if I were to click in order to create a corner point.

00:01:09  But you don't want to do that because if you do,

00:01:12  you'll have just one control handle associated

00:01:15  with this segment, and that's generally a no-no

00:01:17  because you end up with this curving segment

00:01:19  that ends with this kind of flat tire.

00:01:22  So I'm going to go ahead and press Control Z

00:01:24  or Command Z on a Mac.

00:01:25  What you want to do instead, is drag to create

00:01:28  another smooth point like so.

00:01:30  And now notice that the control handle under my cursor,

00:01:33  and my cursor is located downward by the way,

00:01:36  has nothing to do with the segment that I'm about to create.

00:01:40  Instead, it's the opposite control handle

00:01:43  that's informing this segment

00:01:45  while the control handle that I just made

00:01:47  will affect the next segment I draw.

00:01:50  So now I'll go ahead and drag down here

00:01:51  to create another control handle,

00:01:53  and notice that I have established a pattern.

00:01:56  So I started dragging from the top here

00:01:59  in a counter clockwise direction,

00:02:01  which means that I need to continue

00:02:03  in a counter clockwise direction.

00:02:04  If you start clockwise, then just continue clockwise.

00:02:08  So you can draw in either direction you want,

00:02:11  but what you don't want to do is now start dragging

00:02:14  in the wrong direction because you'll get this big loop.

00:02:17  Alright, a couple of other things to note here.

00:02:20  If you press and hold the Spacebar as you're creating

00:02:23  a smooth point, then you can move that point on the fly,

00:02:26  and as soon as you release the Spacebar,

00:02:28  you'll continue changing the curvature of the segment.

00:02:32  You can also press the Shift key

00:02:34  if you want to constrain the angle of your control handles

00:02:37  to the nearest 45 degrees.

00:02:39  But, you cannot do both at the same time.

00:02:42  And so if I were to add the Spacebar

00:02:44  while I have the Shift key down, then I would just continue

00:02:47  to constrain those control handles,

00:02:49  I will not move the anchor point.

00:02:51  So if you want to move that smooth point,

00:02:53  you need to release the Shift key,

00:02:55  then move the point to where you want it to be,

00:02:57  go ahead and release the Spacebar,

00:02:59  then hold the Shift key once again.

00:03:02  A final option that's available to you

00:03:04  is to press the Control key or the Command key on the Mac.

00:03:07  Right now, notice when I don't have any keys down,

00:03:10  that both of my control handles are absolutely symmetrical.

00:03:14  They're both moving along with my cursor.

00:03:17  But if I press the Control key or the Command key

00:03:19  on the Mac, just the control handle under my cursor moves

00:03:23  and the opposite one remains the same length.

00:03:26  I can move around to change its angles,

00:03:28  but its length remains the same.

00:03:30  But if at any time, you release the Control or Command key,

00:03:33  then your control handles are going

00:03:35  to be the same length once again.

00:03:37  Alright, finally, let's say you want to close the path.

00:03:40  I'll go ahead and move my active cursor that has no asterisk

00:03:44  over the first point in the path.

00:03:45  We now see a circle which tells us that we're about to close

00:03:48  the path, but if I were to just click, I'll get

00:03:51  this flattened segment that we're seeing in the preview.

00:03:54  That's not what I want, so in order to get a nice smooth

00:03:56  point at the end, you want to go ahead and drag once again.

00:04:00  Now the good news you'll find as you become

00:04:02  more experienced, is that you're only affecting

00:04:05  the opposite control handle.

00:04:06  You're not affecting the one that's over here

00:04:09  on the left side of the shape, in other words.

00:04:11  It's remaining the same, so that gives you a little more

00:04:14  latitude and control when you're closing the shape.

00:04:17  You also have the option of pressing and holding

00:04:19  the Spacebar to move that closing point on the fly like so.

00:04:24  And when you get it where you want it,

00:04:25  you can release the Spacebar once again

00:04:28  and continue dragging.

00:04:29  So I'm going to go ahead and release to create this shape.

00:04:32  Alright, now let's say you want to make some modifications

00:04:35  because it's not really the smoothest shape

00:04:37  I've ever created.

00:04:38  In that case, go ahead and press and hold the Control key

00:04:40  or the Command key on the Mac to get the lasso arrow tool

00:04:43  on the fly, unfortunately for me, that's the black arrow

00:04:46  tool, which does allow you to drag control handles around

00:04:50  incidentally, so you can move control handles

00:04:52  with the black arrow tool, you just can't move anchor points

00:04:55  because if you click on an anchor point,

00:04:57  you'll end up selecting the entire shape.

00:04:59  You'll also select the entire shape if you click

00:05:01  on a segment, which means I can't see

00:05:04  the control handles down here.

00:05:06  So I need to switch to the white arrow tool by pressing

00:05:08  Control tilde here on a PC

00:05:10  or Command Option Tab on the Mac,

00:05:13  then I'll click on this segment to see its control handles.

00:05:16  Notice the segments just aren't quite long enough,

00:05:19  they should be a little longer in order

00:05:21  to get a nice smooth arc.

00:05:23  And notice if I make them too long like so,

00:05:26  then I'll end up with this kind of rounded corner effect

00:05:29  right here, and if you really go far enough with it,

00:05:32  you'll get the segment to loop around.

00:05:34  Whereas, if you make your control handles too short like so,

00:05:38  then you'll end up with a flattened segment.

00:05:40  So keep in mind that rule of thirds,

00:05:43  which says that the control handles together

00:05:45  should add up to about two-thirds the length

00:05:47  of the curving segment, which is a problem up here.

00:05:50  This guy's too flat, so I'll go ahead and click

00:05:52  on this segment and drag these control handles

00:05:55  out just a little bit like so.

00:05:58  Alright, you can also draw open path outlines if you like,

00:06:01  but you don't want to start dragging on the path outline

00:06:03  because it's selected.

00:06:05  So if I were to click on a selected curving segment like so,

00:06:09  then I will not only see the plus sign next to my pen cursor

00:06:12  but I will also add a smooth point.

00:06:14  So any time you click on a selected curving segment

00:06:17  with the pen tool, you add a smooth point.

00:06:19  Alright, let's say I don't want to do that.

00:06:21  I'll just press Control Shift A or Command Shift A

00:06:23  on the Mac in order to deselect that path outline.

00:06:26  And now, I'll just drag a bunch of times in order to create

00:06:30  some more smooth points, and I'll use the Spacebar

00:06:33  in order to get that guy into a better position.

00:06:35  By the way, you can always edit the points as you're working

00:06:38  just by pressing the Control key

00:06:40  or the Command key on the Mac.

00:06:41  Go ahead and click an anchor point,

00:06:43  adjust its control handles, do whatever you want to it.

00:06:46  You can even move points around incidentally

00:06:48  without deactivating the paths, so notice, as soon

00:06:51  as I release the Control key or the Command key on the Mac,

00:06:53  my path is still active as I can see by the lack of asterisk

00:06:57  and the fact that I have a rubber band preview.

00:07:00  But, if I try to nudge a selected point

00:07:03  using the arrow keys on the keyboard,

00:07:05  the second I press an arrow key, I will deactivate the path

00:07:07  as you're seeing here.

00:07:09  So to reactivate it, you don't want to click

00:07:11  because you're working with smooth points.

00:07:13  Instead, you want to drag and then you can continue dragging

00:07:17  to add more smooth points to your path outline.

00:07:21  Then, once you get the desired effect like so,

00:07:24  and I'll just go ahead and Control-drag or Command-drag

00:07:27  that control handle inward a little bit,

00:07:29  then you can deactivate the path outline just as you can

00:07:31  when you're creating corner points

00:07:33  by pressing the Escape key or the Enter key

00:07:36  or the Return key on the Mac, it's entirely up to you.

00:07:39  Now I'm going to press the V key to switch back

00:07:41  to my black arrow tool, and I'll click off the path outline

00:07:44  to deselect it.

00:07:46  And that's how you create smooth points with a pen tool,

00:07:49  by dragging in a consistent direction, remember that,

00:07:52  here inside Illustrator.
