در این فیلم، ما نگاهی به سه عنصر دیگر از سکته مغزی در Illustrator خواهیم رساند: Caps، Joins و Miter Limit. و همه آنها بر اساس این مفهوم استوار است که Illustrator کمتر درباره وزن کل خط نگران است و بیشتر از دو قسمت وزن خط در هر دو طرف خطوط مسیر نگران است. در مورد ما توجه کنید که من یک خط مستقیم با دو نقطه انتهایی دارم و وزن خط من 200 امتیاز است. بنابراین، به عبارت دیگر، 100 نقطه وزن خط در سمت بالا مسیر و 100 نقطه خط خط زیر مسیر. حالا، من به جلو بروید و بر روی کلمه Stroke کلیک کنید، در اینجا در کنترل پنل کلیک کنید و گزینه Cap capture را در اینجا مشاهده کنید؛ این سه گزینه به ظاهر سکته مغزی در نقطه انتهایی تاثیر می گذارد. آنها فقط بر خطوط مسیر باز می شوند. به طور پیش فرض، Butt Cap انتخاب شده است، به این معنی که سکته مغزی به طور ناگهانی به پایان می رسد. شما دو گزینه دیگر برای شما نیز وجود دارد. شما Round Cap را که قصد داریم پیش برویم و سکته مغزی را در اطراف نقطه انتهایی قرار دهیم، به شکل یک دور در نظر می گیریم همانطور که در اینجا می بینیم. آنچه که ما اساسا داریم، یک دایره در نقطه انتهایی است، با شعاع برابر با نیمی از وزن خط، به عبارت دیگر، 100 امتیاز. چه اتفاقی می افتد سکته مغزی در این مورد گسترش می یابد، 100 نقطه فراتر از نقطه پایان در هر دو جهت است. گزینه دیگری شما یک چرخه طراحی است که پیش می رود و مربع را از آن نقطه انتهایی می گیرد. باز هم، به سمت خارج، نیم وزن خط،
or in our case, 100 points from either end point.
00:01:37 Once again bear in mind, that the Cap Option
00:01:40 only effects open paths;
00:01:41 it has no effect on closed path outlines.
00:01:44 I'm going to go ahead and turn this layer off,
00:01:47 and turn the next layer angle on.
00:01:50 I'll go ahead and click on its path outline to select it.
00:01:53 The next row of options, control the joins.
00:01:56 The joins effect the appearance
00:01:59 of corners in a path outline.
00:02:01 If your path doesn't have any corners,
00:02:03 as in the case of a circle, then you won't see any effect.
00:02:06 I'll once again click on the word Stroke,
00:02:09 up here in the Control Panel,
00:02:10 and notice these corner options right here,
00:02:13 they do indeed control the appearance of corners
00:02:16 in the path outlines, but each of the icons
00:02:18 themselves, are labeled Join.
00:02:21 By default, we have a Miter Join,
00:02:23 meaning that the stroke extends all the way
00:02:25 out until it meets its other side,
00:02:27 and you end up with a sharp corner.
00:02:30 Your other options are a Round Join,
00:02:33 in which case Illustrator goes ahead
00:02:35 and wraps half the line weight around that corner point
00:02:39 as we're seeing right here.
00:02:40 Again, we now have a corner that's made up of a circle,
00:02:44 with a radius of half the line weight,
00:02:46 which in our case, is again, 100 points;
00:02:49 or you can switch to a Bevel Join which is going to
00:02:53 go ahead and slice off that corner.
00:02:55 You may wonder, why Illustrator weights just
00:02:58 a little bit farther out than a corner point,
00:03:01 in order to do the slicing.
00:03:03 That's explained by this Imposition Layer right here.
00:03:06 I'll go ahead and turn it on, so that we can see
00:03:09 the calculation that Illustrator is running.
00:03:11 It's looking at the stroke as it's applied to each segment
00:03:15 independently, so as a result, the corners come out
00:03:18 a little bit, and then it connects the corners,
00:03:21 in order to create that Bevel Join right there.
00:03:24 I'm going to turn that layer off,
00:03:27 so that we can see the effects of the Miter Limit.
00:03:30 To get a sense for how that works,
00:03:32 I'll bring back up the Stroke Panel,
00:03:34 and I'll reset the Corner Option to the Miter Join,
00:03:37 like so, at which point we see this Limit Value,
00:03:41 as you can see right there.
00:03:43 I'm going to go ahead and zoom out,
00:03:45 and then I'll press the A Key
00:03:47 in order to select my white arrow
00:03:50 and I'll click on this Top Anchor Point.
00:03:52 I'll go ahead and drag it down while pressing the Shift Key,
00:03:55 so that I'm making the angle more acute and notice as I do,
00:04:00 that Miter Join goes flying farther out;
00:04:03 in this case, all the way out into the Pace Board.
00:04:07 But, if I keep dragging it down, at some point,
00:04:10 I'm going to lose the Miter Joint entirely
00:04:12 and Illustrator's going to substitute it with a Bevel Joint.
00:04:16 The idea is, your Miter has just gotten too long.
00:04:19 If you disagree, if you want to bring the Miter back,
00:04:22 then just go ahead and press the V Key to switch
00:04:25 back to the Black Arrow Tool,
00:04:26 and click on that Path Outline,
00:04:28 and the reason I'm having you do that,
00:04:30 is notice that when any one point in a path outline
00:04:33 is deselected, you don't see the Fill and Stroke options
00:04:36 up here in the Control Panel.
00:04:38 In order to see those options, all points in a path
00:04:41 have to be selected;
00:04:43 which you can accomplish of course,
00:04:44 by just clicking on the Path Outline with the Black Arrow
00:04:47 and that goes ahead and brings those Fill and Stroke
00:04:49 options back, at which point, I'll click on the word Stroke,
00:04:52 and I'll click in this Limit Value, and I'll press the
00:04:55 Up Arrow Key, a couple of times, and notice if I increase
00:04:58 the limit to 12 X, then I get my Miter Join back,
00:05:04 but I can once again lose that Miter, by pressing the A Key,
00:05:07 and marqueeing that end point right there,
00:05:09 and dragging it down a little more,
00:05:11 and notice the more acute the angle gets,
00:05:13 the more likely I am to lose that Miter.
00:05:16 Now, I'll just go ahead and zoom out a little more,
00:05:18 and maybe pan this art board to the right,
00:05:21 and I'll press the V Key to switch back to
00:05:23 the Black Arrow Tool.
00:05:24 I'll click on this Path Outline to select it,
00:05:26 I'll click on the word Stroke again
00:05:27 and now I'll click in this Limit Value,
00:05:29 and I'll just keep pressing the Up Arrow Key
00:05:31 until I see this Miter Joint come back,
00:05:34 which happens for me at 24 X.
00:05:37 What in the world does that mean?
00:05:39 It's 24 times half the line weight once again.
00:05:44 In our case, Illustrator is allowing the Miter Join
00:05:47 to extend 24 times 100, that is 2400 points
00:05:52 away from that corner point,
00:05:55 and if that's what you want, by all means you can go ahead
00:05:58 and accept that effect even though this is obviously
00:06:01 a pretty radical point.
00:06:03 In my case, I think I'll make things right again,
00:06:05 by pressing the A Key to get the White Arrow Tool,
00:06:07 Clicking the Stop Anchor point to select it
00:06:10 and then dragging up while pressing the Shift Key,
00:06:12 until I regain a semblance of my original Miter like so.
00:06:16 That's how you take advantage
00:06:18 of Caps, Joins and Miter Limits.
00:06:21 In the next movie, I'll show you a practical application.
