من فقط می خواهم بزرگ باشم، بنابراین می توانیم ببینیم چه اتفاقی می افتد. و اکنون می توانید ببینید که در مجموع چهار امتیاز لنگر وجود دارد که همه آنها نقطه صاف هستند. و همانطور که می توانید به یاد بیاورید، یک تضمین کننده مسطح است که ما بین دو بخش منحنی همسایگی یک انتقال صاف داشته باشیم. حالا برای دیدن آنچه که این نقاط صاف به نظر می رسد، به پیش بروید و به ابزار فلش سفید، که شما می توانید با فشار دادن یک کلید را دریافت کنید. و سپس بر روی هر یک از نقاط لنگر کلیک کنید. در آن زمان، نه تنها این نقطه لنگر مربع را می بینید، بلکه دو کنترل دایره ای در هر دو طرف آن با اهرم های مستقیم متصل می شود. این دستگیره های کنترل باعث جذب بخش ها می شوند. آنها مسئول انحنای هستند و به همین ترتیب آنها اساسا مانند آهن ربا هستند که در آن بخش ها مربوط می شوند. و بنابراین متوجه میشویم، اگر این کنترل را کمی دورتر بکشم، قطعه به سمت آن خم می شود. و به هر حال، شما می خواهید در دایره بکشید، نه در اهرم خود، زیرا اگر شما سعی می کنید اهرم را بکشید، شما فقط چیزی را از بین نمی برید، مثل این است. درست است، من قصد دارم به جلو بروید و یک بار دیگر روی نقطه کلیک کنید تا آن را انتخاب کنید. همچنین توجه کنید که من این دسته کنترل را در سمت راست لنگر قرار می دهم، من نیز یکی را در سمت چپ حرکت می دهم، و این به این دلیل است که دو به یکدیگر هماهنگ می شوند.
00:02:29 Now one control handle can get shorter than the other,
00:02:31 but it's going to remain at the same angle,
00:02:34 as we're seeing here.
00:02:36 And that alignment is what defines a smooth point
00:02:39 in Illustrator.
00:02:40 All right, now we saw that if you drag the control handle
00:02:43 farther away from the segment,
00:02:45 the segment is going to bend out toward it.
00:02:47 But if you drag the control handle toward the segment,
00:02:50 it's going to start flattening out, as we're seeing here,
00:02:53 and that's because were no longer requesting
00:02:55 as much curvature.
00:02:56 If you go ahead and drag the control handle
00:02:59 to the other side of the segment,
00:03:01 it's going to bend in the other direction,
00:03:03 and it's going to bend more and more
00:03:05 the farther you drag that control handle.
00:03:08 And now, you can see that we've got
00:03:10 an awful lot of curvature
00:03:12 because the other control handle has moved across
00:03:15 its segment and farther away as well.
00:03:18 All right, let's say I like this amount of curvature
00:03:20 but I don't want my path outline going outside the artboard.
00:03:24 Then I would just go ahead and drag the square smooth point
00:03:27 inward like so.
00:03:29 All right, now I'll just go ahead
00:03:30 and center my zoom once again.
00:03:32 Now just because you're working with smooth points,
00:03:34 doesn't mean you might not get lumpy results.
00:03:37 Notice in this case, for example,
00:03:39 I'm getting an extremely lumpy curve,
00:03:42 and that's because the control handle
00:03:45 affects the way the segment exits an anchor point
00:03:48 and how it enters the next one.
00:03:50 And so in this case, both of the control handles
00:03:53 on either side of the segment are requesting
00:03:56 a ton of curvature, and that's creating
00:03:59 a kind of wavy segment, as we're seeing right here.
00:04:02 And so the solution is to just go ahead
00:04:05 and bring the control handles in
00:04:07 so that we get smoother results as we're seeing right here.
00:04:12 Now another way to see your control handles
00:04:14 is to click on a segment, in which case,
00:04:17 you'll see the control handle that's directing
00:04:19 the way the segment exits an anchor point,
00:04:21 as well as the one that defines how it's entering
00:04:24 the next anchor point.
00:04:26 Now watch what happens if I take a control handle
00:04:28 and bend it totally in the other direction.
00:04:32 We're going to end up with a loop
00:04:34 inside of our path outline.
00:04:36 That's rarely desirable, and so the solution
00:04:39 is to just go ahead and put things back the way they were.
00:04:42 You also have the option, when you're working
00:04:44 with the white arrow, of dragging directly on a segment
00:04:48 like so, in which case, you're going to modify
00:04:50 the bending of that segment.
00:04:53 And you have a lot of latitude these days.
00:04:55 You can drag that segment just about anywhere you want,
00:04:58 and the control handles will come along with it.
00:05:01 You can also constrain the drag by pressing and holding
00:05:04 the shift key, in which case,
00:05:06 those handles are going to lock to the nearest 45 degrees.
00:05:09 You can also lock your control handles
00:05:11 by shift dragging directly on them, like so,
00:05:15 which is great if you're looking for absolutely vertical
00:05:18 or horizontal alignment.
00:05:20 And so I'll go ahead and make these guys up here
00:05:23 exactly horizontal like so.
00:05:25 Now you're going to be doing a ton of work
00:05:27 with control handles inside Illustrator.
00:05:30 And you're going to run into situations
00:05:32 where you're not getting smooth results.
00:05:34 And any time that happens, I want you to take a look
00:05:37 at an arc.
00:05:38 So go to the Line Segment Tool,
00:05:40 and then select the Arc Tool.
00:05:42 And just go ahead and draw a big arc.
00:05:45 And in my case, I want to flip it
00:05:46 just for the sake of demonstration here.
00:05:49 And after you draw the arc, then press the a key
00:05:52 to switch to the White Arrow Tool,
00:05:53 and go ahead and click off the line to deselect it.
00:05:56 And then click on its segment, and you'll see
00:05:59 how the control handles are arranged.
00:06:02 And I want you to notice that we have two control handles
00:06:05 for curving segment.
00:06:07 That's very important.
00:06:08 You don't want to have just one control handle like this
00:06:11 because you'll end up with a kind of flat tire effect.
00:06:14 So you definitely want two handles for every curving segment
00:06:17 and you want those handles together
00:06:20 to occupy about 2/3 the length of the segment.
00:06:25 So in other words, about 1/3 of the length of the segment
00:06:28 is not covered by handles; and the other 2/3 are.
00:06:31 That is not to say that they have to be even in length
00:06:33 by the way.
00:06:35 One can be longer, and the other can be shorter,
00:06:37 and you can still end up with very smooth results
00:06:40 like this.
00:06:42 And that friends is how smooth points really work
00:06:44 inside Illustrator.
00:06:46 In the next movie, I'll show you how to draw smooth points
00:06:49 with the Pen Tool.
