آموزش تصویری ایلوستریتور Illustrator CC Drawing freeform path outlines

 

 

00:01:47  all the way over to the right and click okay,

00:01:50  and now if I draw the path, even if

00:01:53  the preview's looking pretty chunky,

00:01:55  I should expect to see smoother results.

00:01:58  And sure enough, as soon as I release the mouse button

00:02:01  I see a very smooth shape indeed.

00:02:04  Now, the one unfortunate problem with it

00:02:06  is that it's an open path outline instead of a closed one.

00:02:09  Notice if I press the A key to switch to my wide arrow tool

00:02:13  and I click on one of these points up here

00:02:15  at the top of the heart, the two points

00:02:18  are not joined together by default.

00:02:20  Now you can join them, just by moving

00:02:23  one directly on the other like so,

00:02:25  and then marquee-ing those two points

00:02:27  in order to make sure thy're both selected

00:02:29  and then just going up to this option right here

00:02:31  connect selected endpoints, and that'll

00:02:33  go ahead and fuse those endpoints together,

00:02:36  in order to create a closed path outline like so.

00:02:39  So that's one way to work, the other is to

00:02:41  redraw the shape, subject to a different setting.

00:02:44  And to demonstrate that, I'll press the backspace key

00:02:46  a couple of times here on a PC, that would be the delete key

00:02:50  on the Mac, in order to get rid of that shape,

00:02:52  and I'll switch back to my pencil tool once again

00:02:55  and I'll press the enter key, or the return key

00:02:57  on the Mac, to bring up the dialogue box.

00:02:59  Now this dialogue box has been in a high state

00:03:01  of transition, so you may see different stuff.

00:03:04  But currently we have this checkbox

00:03:06  "Close paths when ends are within", however many pixels,

00:03:10  by default it's set to fifteen, so in other words

00:03:13  you need to make sure that you end your

00:03:15  path outline within fifteen screen pixels

00:03:18  of where you begin it, and so I'm

00:03:20  gonna go ahead and turn that checkbox on

00:03:21  and click okay, and now I'll go ahead

00:03:24  and draw the shape once again,

00:03:26  but I want you to note the cursor

00:03:27  see how the pencil has a little asterisk next to it?

00:03:30  That tells you that you're creating

00:03:31  a new path outline, like so, but notice

00:03:35  as soon as we arrive at the very first point

00:03:38  inside of the shape up here at the top,

00:03:41  that we're gonna see a circle next to the cursor,

00:03:44  which tells us that we're gonna close the path outline.

00:03:46  Now the one problem with it, at this point

00:03:48  is that it's rounded off, so the closed points tend to be

00:03:53  what are known as smooth points, as opposed to corners.

00:03:56  If what you want is a corner, then try beginning

00:03:59  the draw at a different location.

00:04:02  So for example, I'll just go ahead and

00:04:03  press the backspace key there, and again

00:04:05  that's the delete key on a Mac,

00:04:06  and then I'll draw the hump of the heart,

00:04:09  and then I'll come back around

00:04:11  and draw the center of it, like so,

00:04:14  and then I'll go ahead and connect those endpoints

00:04:16  In order to create a nice, clean, smooth, fluid shape

00:04:19  complete with corners at the top, and the bottom.

00:04:23  Alright, now I'm gonna make my shape a little bigger

00:04:26  by clicking on the word transform up here

00:04:28  in the control panel, or again if you don't see it

00:04:30  click the X, Y, W, or H and I'm gonna make sure

00:04:34  that both the values are linked together,

00:04:36  that is both the width and height values,

00:04:38  and then I'll change the width

00:04:40  value to, let's say 500 points.

00:04:43  And next, I'll go ahead and give the shape

00:04:45  a thicker line weight by taking that

00:04:48  stroke value up to eight points,

00:04:49  and I'll click on the fill icon, which is the first stroke

00:04:51  up here in the control panel, and I'll change the color

00:04:54  to the shade of red, Rx237 Gx28 Bx36

00:04:59  in order to create this final effect here.

00:05:02  And that folks is the basics of how you use

00:05:04  the best free-form drawing tool in the business,

00:05:07  the new and improved pencil tool here inside Illustrator.

از سحر محاسبات شخصی، بشر به دنبال وسیله ای است که شما فقط می توانید آن را جلب کنید. شما می دانید، مانند زمانی که شما با یک مداد 20 سانتیمتر یک قطعه کاغذی یک سنت را قرعه کشی کنید. به جز اینکه می خواهید این کار را با یک میلیارد دلار خرج کنید به جای استفاده از رایانه، این رویای ما حدود 27 سال فرار کرده است، که شوخی نیست. طول زمان دقیق آن است. اما اکنون یک واقعیت است و آن ابزار Pencil است. نه، واقعا. ابزار مداد مورد استفاده قرار گرفت وحشتناک بود، اما حالا عالی است. بنابراین، خوب، این را تماشا کنید. این چیزی است که به نظر می رسد زمانی که شما با ابزار Pencil Tool Draw می کنید. این یک خراب شدن قطار کوچکی است، درست است؟ من واقعا آن را خراب کردم. اما پس از آنکه دکمه ی ماوس را آزاد کردم، واقعا، من با استفاده از این ماوس رسم می کنم، این تبدیل به این می شود. دوباره آن را می بینم. در اینجا من نقاشی می کنم و این بعد است و شما می توانم این کار را هم انجام دهم. می دانم، از یک طرف فکر می کنم، "واقعا؟" من باید صدها دلار در سال برای یک مداد پرداخت کنم؟ "اما از سوی دیگر، این یک مداد است که می داند آنچه شما در نظر داشتید برای رسیدن به لحظه ای که آزاد می کنید. این مثل یک مداد هوشمند است، حتی دقیق تر.

  just so we can really see what's going on.

00:00:59  All right, now I want to make a copy of this guy,

00:01:01  so I'll go ahead and drag it by its center point

00:01:03  over to the other side of the door,

00:01:05  and then I'll press the Alt key or the Opt key on a Mac,

00:01:08  and drop it into place in order to create a copy like so.

00:01:12  And I just want to make sure that this guy is

00:01:14  the same distance from the door as the other rectangle,

00:01:18  as the other window, and notice, now, did you see that,

00:01:20  just a second ago?

00:01:21  Boy, it kind of went away there.

00:01:23  There it is.

00:01:24  We have new Smart Guide action in this most recent version

00:01:27  of Illustrator, so we're seeing that the two windows are

00:01:30  the same distance from that door,

00:01:33  which is exactly what I want.

00:01:35  All right, now, I want to subtract these windows

00:01:37  from the house, so I'm going to click off the house

00:01:39  in order to deselect it, because any time you're doing

00:01:42  these combinations, you want everything deselected

00:01:45  inside the illustration, and then just go ahead

00:01:48  and scribble inside each one of the windows.

00:01:51  And you want to keep your scribble inside there.

00:01:54  You don't want to start out and go in like that,

00:01:57  because that's going to end up combining

00:01:59  those two shapes together, so I'm going

00:02:02  to undo that change and just scribble inside

00:02:04  of here once again.

00:02:05  All right, now, at this point, it's difficult

00:02:07  to tell if what we have are rectangles

00:02:09  that are filled with white, or whether they're transparent,

00:02:12  so I'm going to make a couple of changes here.

00:02:15  First, I'm going to click inside this window,

00:02:17  and notice I can't get to it, and that's because

00:02:19  it is a hole, so I'm not clicking on anything.

00:02:21  I need to click on its outline to select it,

00:02:24  and then I'll Shift+click on this guy

00:02:25  to select him as well, and now I'll go up here

00:02:28  to the Control Panel and increase that line weight value

00:02:31  once again to six points.

00:02:33  And now I'm going to draw a straight line,

00:02:35  don't make it a zigzag, just draw a straight line.

00:02:37  That is not a horizontal line, however,

00:02:40  so I'm going to try again by dragging more horizontally,

00:02:43  and then I'm going to drag vertically as well,

00:02:47  in order to create a vertical line.

00:02:49  All right, now I'll click on one

00:02:50  and Shift+click on the other to select them both,

00:02:53  and I'll go up here to the Control Panel,

00:02:55  make sure Align to Selection is active,

00:02:58  and then click on the second icon,

00:03:00  Horizontal Align Center, and then click on the fifth icon,

00:03:03  Vertical Align Center, in order to align those guys

00:03:06  with each other.

00:03:07  And then I want to make sure that they're centered

00:03:09  inside the window, so I'm going to press Ctrl+Y,

00:03:11  or Cmd+Y on the Mac, to switch to the Outline mode,

00:03:14  and that way I can see that center point,

00:03:17  right there in the center of the rectangle.

00:03:19  And I'll go ahead and drag these guys into alignment,

00:03:22  so that they more or less snap, not really necessarily

00:03:24  getting any snapping action,

00:03:26  but I can see that's close enough.

00:03:28  And I'll press Ctrl+Y, or Cmd+Y on the Mac,

00:03:30  to switch back to the Preview mode,

00:03:32  and I'll increase the line weight value

00:03:34  to a whopping 10 points, let's say, and for some reason,

00:03:38  I'm ending up with round caps, and if that bothers you,

00:03:41  obviously you can click on the word Stroke

00:03:44  and change them back to butt caps.

00:03:46  Doesn't really matter, but I want you to see that behavior.

00:03:49  And then, I'm going to switch back to the Black Arrow tool,

00:03:52  up here at the top of the Toolbox, and I'm going

00:03:54  to grab these guys like so, click on one,

00:03:56  Shift+click on the other, and then drag them over

00:03:59  until they intersect with the center of the other window.

00:04:02  I've got the Shift key down, I'm adding the Alt key,

00:04:05  or the Opt key on the Mac, in order to create a clone

00:04:08  of those lines like so.

00:04:10  And now go ahead and Shift+click on the other guys,

00:04:13  the originals, and I'll right-click anywhere

00:04:15  inside the document window, choose Arrange,

00:04:17  and choose Send to Back, and you can see

00:04:20  that we are now seeing through the windows

00:04:22  to those panes.

00:04:24  All right, now let's say I want to recolor the roof.

00:04:27  In that case, I'll go ahead and select my Shaper tool

00:04:29  once again, and instead of clicking inside the roof,

00:04:32  I'll double-click in it, in order to select

00:04:35  just that triangular path outline,

00:04:37  and then I'll Shift+click on the chimney to select it.

00:04:40  Shift+clicking, even with the Shaper tool,

00:04:43  is going to select multiple path outlines,

00:04:45  and then I can change the Fill color

00:04:47  up here in the Control panel to, let's say,

00:04:49  this darkish shade of blue over here.

00:04:51  And notice what happens if I now click off the paths

00:04:54  and deselect them.

00:04:56  I have managed to change the color of the roof and chimney,

00:04:58  but I have lost any stroke between the two.

00:05:02  So I don't have a stroke, as you can see here,

00:05:04  and that's just the kind of stuff that you can do

00:05:06  with Dynamic Shaper Groups here inside Illustrator.

00:05:10  I want you to also notice that, even though we've called

00:05:12  for mitered joins where our strokes are concerned,

00:05:15  we end up with round joins at the path intersections.

00:05:20  So, for whatever reason, that is something

00:05:22  that Illustrator goes ahead and does.

00:05:24  So let's say I want to bring back a stroke

00:05:26  along the roof line.

00:05:28  Well, the easiest way to do that is to zoom out

00:05:30  by pressing Ctrl+0 or Cmd+0 on a Mac,

00:05:33  and now I'm going to switch back

00:05:34  to my Black Arrow tool.

00:05:35  Now, of course, if I were to click on that path,

00:05:38  I'm going to select the whole darn thing,

00:05:40  as indicated by these red outlines here,

00:05:43  because, after all, I'm working on a red layer.

00:05:45  If you had the Bounding Box turned on,

00:05:47  you could see it as well.

00:05:49  I don't want to edit the entire house, however,

00:05:51  so I'm going to switch to the Group Isolation mode

00:05:53  by double-clicking on the roof.

00:05:57  And so, now notice, because I double-clicked

00:05:59  I'm seeing that I'm working inside the Shaper Group

00:06:02  up here in the upper left corner of the window,

00:06:05  and now, what that means is I can click on the roof

00:06:07  to select it independently, Shift+click on the chimney

00:06:10  to select it independently as well,

00:06:12  and then I'm just going to Shift+drag these elements up,

00:06:15  so that they're no longer intersecting the green house,

00:06:18  and that restores the stroke, as you can see.

00:06:20  And now, if I drag these guys back down,

00:06:23  we have managed to reinstate that stroke

00:06:26  along the bottom of the roof.

00:06:28  All right, that's a little low, however, so I'll probably

00:06:30  Shift+Up Arrow in order to nudge the roof

00:06:32  up a little bit, and then, now that I'm done

00:06:35  modifying the roof, I'll go ahead

00:06:36  and press the Esc key in order to escape

00:06:39  out of that Group Isolation mode,

00:06:41  at which point, if I were to click on the house,

00:06:43  I would end up selecting the entire thing.

00:06:45  I don't want it selected, however,

00:06:47  so I'm just going to click off the house

00:06:49  in order to deselect it, and then I'm going

00:06:52  to hide my Guide lines by going to the View menu,

00:06:55  choose Guides, and choose Hide Guides

00:06:58  to turn them off.

00:07:00  And that's how you subtract paths in order

00:07:02  to create the windows, as well as split paths

00:07:04  in order to create this independent roof and chimney

00:07:07  using the new Shaper tool here inside Illustrator.

آموزش تصویری ایلوستریتور Illustrator CC Combining paths with the Shaper tool

 

 

 

00:00:38  But notice when I release the mouse button

00:00:41  that I end up getting a small equilateral triangle.

00:00:45  So every time you create a triangle with this tool,

00:00:48  all three segments are the same length.

00:00:51  Alright now I'll go ahead and click on the triangle

00:00:52  to select it,

00:00:54  and notice that it is a smart polygon,

00:00:56  as indicated by the word polygon over here

00:00:58  on the far right side of the Control Panel,

00:01:00  which means that I can drag this Plus-Minus widget

00:01:03  in order to add or delete sides.

00:01:06  Of course, I still want three sides,

00:01:08  so I'll leave that alone.

00:01:10  We also have this accurate center point,

00:01:12  which is located equidistant

00:01:14  from each one of the sides.

00:01:16  We'll see how that changes in just a moment.

00:01:19  So I'm gonna go ahead and drag this guy

00:01:21  all the way over

00:01:23  to some place along the far left side of the document,

00:01:25  and now I'm gonna stretch it by dragging

00:01:28  the bottom right handle

00:01:29  all the way until the shape is more or less centered

00:01:32  as I can see right here.

00:01:34  But notice that the shape is expanded,

00:01:36  so it's now a static path outline,

00:01:38  as indicated by the word Path

00:01:40  on the far left side of the Control Panel,

00:01:42  and we have a less accurate center point,

00:01:44  it's too high as you can see here,

00:01:46  because it now represents the center

00:01:48  of the bounding box,

00:01:49  but it does match the center of the width of the shape.

00:01:52  So everything's good.

00:01:54  Alright now I'll go ahead and draw a chimney

00:01:56  as another rectangle right there.

00:01:59  Now let's say I wanna go ahead and combine these paths.

00:02:02  You do that by making sure the paths

00:02:04  are deselected, as we're seeing right here,

00:02:06  that's very important.

00:02:07  And then you wanna draw a zigzag

00:02:09  inside of your path outlines.

00:02:13  So notice if I just draw a zigzag like so,

00:02:16  then I'm gonna combine the chimney

00:02:18  along with the roof in order to create

00:02:21  this effect here.

00:02:23  I'm gonna undo that however,

00:02:25  so that I can show you a few other options,

00:02:27  and I'll do that of course

00:02:28  by pressing CTRL+Z,

00:02:29  or Command + Z on a Mac.

00:02:30  If you end up starting your drag outside the boundary

00:02:33  of the path outline, like so,

00:02:35  and then dragging in,

00:02:37  then you're going to delete the shape

00:02:39  rather than add it.

00:02:41  So you wanna make sure

00:02:42  when you're adding shapes together,

00:02:43  that you go ahead and start your drag

00:02:46  inside the path outline like so,

00:02:48  and stay inside the path as well,

00:02:50  and you wanna make sure that you scribble

00:02:52  out into the other path that you want to combine.

00:02:55  Now you can scribble all over the place

00:02:57  if you like, but you don't have to.

00:02:59  All you need to do is make sure

00:03:01  you're creating a letter Z,

00:03:03  and let me show you what that looks like.

00:03:05  I'll go ahead and undo the combination

00:03:07  of those paths again,

00:03:08  and I will start inside here,

00:03:10  so you need to drag down in this case,

00:03:12  then back, and then like so,

00:03:15  in order to draw a Z,

00:03:17  so you just need three back and forths on your zigzag.

00:03:20  And then I can just go ahead and drag this guy

00:03:23  all the way down to here,

00:03:25  and that'll combine all three of my paths into one.

00:03:29  Alright now let's say that you wanna change the color

00:03:31  of the paths, because after all,

00:03:32  the shaper tool always gives you these light gray fills.

00:03:35  Why then, just go ahead and click on the path outline

00:03:38  to select it, and you'll see your outline light up.

00:03:40  In my case it's appearing red,

00:03:42  because I'm working on a red layer.

00:03:45  I am not seeing any anchor points or handles

00:03:47  and that's because you cannot modify anchor points

00:03:50  using this tool.

00:03:51  If that bothers you,

00:03:53  then you can go up to the View menu

00:03:54  and choose Show Bounding Box

00:03:56  in order to see a big bounding box surrounding the shape,

00:03:59  so that you know for sure that it's selected.

00:04:02  I don't want that however,

00:04:03  so I'm gonna turn the bounding box off

00:04:05  by choosing the Hide Bounding Box command.

00:04:08  And now at this point, I can go up to the Fill Swatch,

00:04:10  this first swatch up here in the Control Panel,

00:04:13  and I can change it to, let's say,

00:04:15  this light shade of green right there.

00:04:17  And I'll also increase the line weight value

00:04:20  to 6 points, in order to produce this effect.

00:04:24  Alright, now I'm gonna add a door,

00:04:25  and incidentally, there's no rule that says you have to

00:04:28  draw your shapes with the shaper tool.

00:04:30  And so, for example, I can go ahead and create the door

00:04:33  as a rectangle using the Rectangle Tool,

00:04:36  and now I'll just go ahead and draw a door

00:04:38  that looks something like this, let's say,

00:04:41  so that it's centerpoint is centered

00:04:44  on that vertical guideline,

00:04:46  and I'll go ahead and release, and now,

00:04:47  I'll get rid of that little extra edge

00:04:49  down there at the bottom of the door,

00:04:51  by switching to the Shaper Tool,

00:04:53  and then you wanna click off the shape to deselect it,

00:04:56  because notice what happens if I start dragging

00:04:58  on this guide while it's selected,

00:05:00  it's very possible I'm gonna get rid of it

00:05:02  or something else is gonna go wrong.

00:05:04  That's not what I want, so,

00:05:06  I'll go ahead and undo that and click off the shape

00:05:08  to deselect it, and then, I'll just go ahead and drag

00:05:11  into the shape, so I'm crossing the boundary,

00:05:13  I'm not crossing all the way into the house, like that,

00:05:16  because if I did that, then I would subtract the door

00:05:18  as a hole in the house, that's not what I want,

00:05:21  so I'll just go ahead and press CTRL + Z,

00:05:23  Command + Z on a Mac,

00:05:24  and I will drag in and along the edge,

00:05:27  just right there, notice I've got another letter Z,

00:05:29  albeit at an angle, and then I'll release,

00:05:32  and that goes ahead and subtracts away that area.

00:05:35  Now what I wanna do is color that door differently,

00:05:37  and so I'm gonna click on it to select the entire

00:05:39  shaper group, and by the way,

00:05:42  you can tell it's a shaper group,

00:05:43  a special new group inside Illustrator,

00:05:45  because of the words "Shaper Group"

00:05:47  on the far left side of the Control Panel.

00:05:49  And then, I will click once again,

00:05:51  in order to isolate this region.

00:05:53  And that little dot pattern is showing you

00:05:55  that you now have the option of changing the color

00:05:58  of that region just by going up to the Fill Swatch,

00:06:01  once again, and changing it to what ever you like.

00:06:03  I'm gonna go with this light shade of orange,

00:06:06  in order to recolor the door like so.

00:06:09  And here's where things get exciting.

00:06:11  I'll just go ahead and press the Escape key

00:06:13  in order to hide that panel.

00:06:14  Let's say you wanna modify any one of these shapes.

00:06:17  Then just go ahead and double-click on it,

00:06:20  in order to select that shape.

00:06:22  So that's a double-click,

00:06:24  that will give you access, in our case,

00:06:25  to this rectangle,

00:06:27  at which point I can go ahead and change it's size

00:06:29  by dragging on one of these handles,

00:06:31  or I can move it to a different location.

00:06:34  And so what we have here is a dynamic

00:06:36  combination of paths, so you can change the paths around

00:06:39  as much as you like.

00:06:41  You can even drag the thing way out there, like so,

00:06:44  if you do though and then you drag it back in,

00:06:46  you're gonna mess things up.

00:06:47  So I'll just go ahead and press CTRL + Z a couple times

00:06:49  in order to undo that change.

00:06:51  And so for example, if I decide the door is too tall,

00:06:53  I can now just click on it,

00:06:55  because I'm in the Shape Editing Mode,

00:06:57  and I could reduce it's height, like so,

00:07:01  in order to get a shorter door,

00:07:02  I could make it narrower

00:07:04  by dragging one of these side handles

00:07:06  and pressing the ALT key,

00:07:07  or the Option key on a Mac,

00:07:09  so that I'm scaling both sides inward

00:07:11  with respect to the center.

00:07:13  And in my case, I really want it to be a little taller,

00:07:15  so I'm gonna drag the top up, like so,

00:07:18  and then when you're done,

00:07:19  just click off the path outline

00:07:21  to deselect it.

00:07:23  And that, friends, is how you dynamically combine paths

00:07:26  using the Shaper Tool.

00:07:28  And in the next movie,

00:07:29  I'll show you how to subtract paths

00:07:30  in order to create holes.

  to switch back to my Black Arrow tool.

00:01:00  And I'm going to move this shape to right about there

00:01:04  while I press the alt key or the option key on the Mac

00:01:07  to create a duplicate of it.

00:01:08  And then I'll press ctrl + C, ctrl + F,

00:01:11  or cmd + C, cmd + F, to make a copy of this shape,

00:01:14  and I'll click on the word Transform

00:01:16  to bring up the transform panel,

00:01:18  make sure that the right point in the reference point matrix

00:01:21  is selected, then go to the fly out menu

00:01:23  and choose Flip Horizontal

00:01:25  in order to flip that shape like so.

00:01:27  And now I'm just going to marquee both these shapes

00:01:29  and drag them down.

00:01:30  And what I want to do is create a slight gap

00:01:32  between these three shapes like so.

00:01:36  All right, so now let's say I go ahead and marquee

00:01:38  all three shapes to select them,

00:01:40  and I grab my Shape Builder tool and I press the shift key

00:01:43  so that I can marquee all three shapes,

00:01:45  and that basically doesn't do anything.

00:01:48  They're still independent shapes as we can see

00:01:51  by pressing the V key to switch back

00:01:52  to the Black Arrow tool.

00:01:54  And as you can see, I can drag them around

00:01:56  just as much as I ever could.

00:01:57  All right, so I'll press ctrl + Z,

00:01:59  or cmd + Z on the Mac to undo that change,

00:02:01  and then I'll just go ahead and marquee though shapes again,

00:02:03  click on the Shape Builder tool

00:02:05  and this time I'll press the enter key

00:02:07  or the return key on the Mac to bring up

00:02:09  the Shape Builder Tool Options dialog box,

00:02:11  and I'll turn on Gap Detection.

00:02:13  And now you have the option of setting how big the gap is.

00:02:17  And you can just fool around with that to see what works,

00:02:20  but I'm going to set it to medium,

00:02:22  or you can dial in your own custom value if you like.

00:02:25  And then I'll go ahead and click OK,

00:02:27  and now if I once again shift marquee those shapes,

00:02:31  I join them altogether because Illustrator

00:02:34  is filling in the gap.

00:02:35  Now it's not necessarily the most beautiful effect,

00:02:38  as you can see right here,

00:02:39  but it is possible and it may be the kind of thing

00:02:41  that you'll find useful at some point in time.

00:02:44  All right, I'm going to zoom back out

00:02:46  and press the backspace key to get rid of that thing.

00:02:48  Now let's check out what happens when you work with

00:02:50  absolutely open unfilled paths.

00:02:53  So I'm going to go ahead and select, let's say,

00:02:57  the Arc tool right here,

00:02:58  and then I'll draw a big arc like so

00:03:00  while pressing the shift key to constrain it

00:03:02  to exactly a quarter circle like so.

00:03:05  And it happens to have a width and a height of 400 pts,

00:03:09  not really all that important but there it is.

00:03:11  All right, now I'm going to go ahead and cross this arc

00:03:14  with a straight line that I'll draw

00:03:16  with the Line Segment tool.

00:03:17  So I want to get my cursor into the right position here,

00:03:20  and thanks to the fact I have smart guides on,

00:03:22  I can see those intersect lines.

00:03:24  And now I'll drag up into the right

00:03:26  while pressing the shift key like so.

00:03:29  And that'll give me a perfectly diagonal line.

00:03:31  All right, now I'm going to press the V key

00:03:33  to switch back to the Black Arrow tool.

00:03:34  I'll marquee both of these paths

00:03:36  and let's set the line weight to something like 10 pts

00:03:39  so we can see what we're doing.

00:03:40  Now if you go over here to the Shape Builder tool

00:03:43  and you try to do something to these lines

00:03:45  like shift marquee them, nothing really happens

00:03:49  as you can see.

00:03:50  And that's because once again, they are open

00:03:52  and they are unfilled.

00:03:54  If you would like something to happen,

00:03:55  if you would like to split the arc at that straight line,

00:03:57  for example, then go ahead and press the enter key

00:04:00  or the return key on the Mac,

00:04:02  to bring up the Shape Builder Options dialog box.

00:04:04  And you might as well turn off Gap Detection

00:04:06  while we're here, and then turn on this checkbox,

00:04:09  In Merge Mode, Clicking Stroke Splits the Path,

00:04:12  and click OK in order to dismiss the dialog box.

00:04:15  And now notice, if you hover over that stroke,

00:04:18  it turns red, at which point you can click on it.

00:04:21  And with any luck, that'll work.

00:04:23  It doesn't always work but in my case it did,

00:04:25  because I can see a little anchor point at this location,

00:04:28  and now I'm going to click on a straight line as well

00:04:30  to break it hopefully.

00:04:32  And now I'll press the V key to switch back

00:04:34  to the Black Arrow tool.

00:04:35  I'll click off the paths to deselect them.

00:04:37  This guy is now split like so,

00:04:39  and this guy did not get split.

00:04:41  Notice that?

00:04:42  So it doesn't always work the way it's supposed to,

00:04:45  but I'm going to go ahead and press the A key

00:04:48  to switch to my White Arrow tool,

00:04:50  and I'll click on this end point right there

00:04:52  to select it and I'll drag it until it snaps into alignment

00:04:55  with the end of the arc.

00:04:56  And then I'll drag it again to the other end of the arc

00:04:59  and press the alt key or the option key on the Mac,

00:05:02  to create a copy of that line.

00:05:04  I'll press the V key to switch back to my Black Arrow tool.

00:05:07  I'll click on this arc to select it

00:05:09  and then I'll press the backspace key to get rid of it,

00:05:11  and now I'm going to marquee all three of these lines

00:05:14  like so, and I'll go up to the Object menu,

00:05:16  choose Path and then choose Join,

00:05:19  or you can just press ctrl + J or cmd + J on the Mac

00:05:22  in order to join those open paths into a single closed one.

00:05:26  All right, now I'm going to click on the word Transform

00:05:28  up here in the control panel,

00:05:30  and I'm going to change my rotate value right there,

00:05:32  but first I'm going to rotate around the center.

00:05:35  And now I'll dial in a rotate value

00:05:38  of -90-22.5.

00:05:42  And the reason -22.5 is because that's half

00:05:44  of the 45 degrees that are left to this arc.

00:05:47  And now I'll press the enter key,

00:05:49  or the return key on the Mac, and that's going to rotate

00:05:51  my shape upward like so.

00:05:52  And now if I grab my Ellipse tool and I draw a little circle

00:05:56  in there and I go up to the control panel

00:05:59  and click on the first swatch,

00:06:01  change it to this dark shade of red

00:06:03  and then click on the second swatch for the stroke

00:06:05  and change it to none, and then press the V key

00:06:08  to switch back to my Black Arrow tool

00:06:10  and drag this guy down just a little bit

00:06:13  and click off of it, I end up with a pepperoni pizza!

00:06:16  And so that's how you work with those two

00:06:18  Shape Builder Tool Options, which are Gap Detection

00:06:21  and In Merge Mode, Clicking Stroke Splits the Path.
