00:00:00,000 --> 00:00:06,000
This is tutorial number 50 and it covers how to use the Stiffender feature within KTF-V5.
2
00:00:06,000 --> 00:00:11,000
To start off, open up tutorial part number 50 which is located on the DVD.
3
00:00:11,000 --> 00:00:20,000
Now the Stiffender feature is found in the toolbox over here, or if you go to insert sketch-based features, Stiffender.
4
00:00:20,000 --> 00:00:29,000
Now to use the Stiffender all you need is one profile or one line that's opened and from that you're able to make a Stiffender.
5
00:00:29,000 --> 00:00:34,000
So what we're going to be doing is creating a line along here and extruding it across.
6
00:00:34,000 --> 00:00:39,000
So to start off, let's click this face here and we'll click sketch.
7
00:00:39,000 --> 00:00:45,000
Now when you're making it, when you're drawing these lines in here, there's two different ways to do it.
8
00:00:45,000 --> 00:00:52,000
You can go from line to line, touching the points there, or you can do it inside the box without touching any lines.
9
00:00:52,000 --> 00:00:55,000
So this is two different ways of making a Stiffender.
10
00:00:55,000 --> 00:01:00,000
The first one we're going to make is just draw lines that are inside this box, not touching the edges.
11
00:01:00,000 --> 00:01:06,000
So let's just rotate it around a bit and just draw a little line just like that in there.
12
00:01:06,000 --> 00:01:10,000
And if you look on the side, you can see that it's inside the box.
13
00:01:10,000 --> 00:01:17,000
Now go back up, click Stiffender, and we're going to be using the from side mode.
14
00:01:17,000 --> 00:01:22,000
You're going to be able to use the from top mode when you click on the points to points.
15
00:01:22,000 --> 00:01:29,000
So if we zoom in, what this is going to let us do is we're able to, with the thickens, slowly bring that sketch out.
16
00:01:29,000 --> 00:01:40,000
Now you'll notice that our sketch is only in here, but what this is going to do with the Stiffender is it automatically extends it out to the edges and kind of cleans everything out for you.
17
00:01:40,000 --> 00:01:45,000
So let's bring this out 20 and we'll click OK.
18
00:01:45,000 --> 00:01:48,000
And the Stiffenders come out 20 millimeters.
19
00:01:48,000 --> 00:01:53,000
Now let's double click on this sketch and let's just move this around.
20
00:01:53,000 --> 00:01:59,000
So let's drag this guy more over to here and let's see what our result is.
21
00:01:59,000 --> 00:02:03,000
And you can see that now our Stiffender has moved over also.
22
00:02:03,000 --> 00:02:09,000
Now let's delete this Stiffender and we're going to do it the other way that I was talking about.
23
00:02:09,000 --> 00:02:12,000
So let's click this face, click Sketch.
24
00:02:12,000 --> 00:02:23,000
Now click this face and we'll project the edges, turn them into construction lines, and now we'll sketch from point to point.
25
00:02:23,000 --> 00:02:31,000
So we'll do one from this point along here to a point along there.
26
00:02:31,000 --> 00:02:41,000
Now let's put a little angle in there so we can play with it after.
27
00:02:41,000 --> 00:02:45,000
So we have an angle about 30 degrees. So let's put in 30.
28
00:02:45,000 --> 00:02:50,000
And let's go back up and let's click the Stiffender.
29
00:02:50,000 --> 00:02:54,000
And from this one you can use the from side or you can use from top.
30
00:02:54,000 --> 00:02:59,000
So right now on the from side we're making exactly the same one that we had before.
31
00:02:59,000 --> 00:03:05,000
From top we're going to make one that's going to have a hollow opening in it.
32
00:03:05,000 --> 00:03:09,000
So let's click OK.
33
00:03:09,000 --> 00:03:22,000
And let's click on this surface here and we'll sketch out quickly a rectangle and just cut this a little bit out just so you can see the gap in there.
34
00:03:22,000 --> 00:03:30,000
So if you can see in the back there you have a gap and that's what using the from top compared to the side is there.
35
00:03:30,000 --> 00:03:34,000
And let's go back.
36
00:03:34,000 --> 00:03:39,000
Now let's make the stiffener again using this point to point and we're going to use the from side.
37
00:03:39,000 --> 00:03:42,000
So this is just like the other one. We're just going to extend it out 25.
38
00:03:42,000 --> 00:03:44,000
Click OK.
39
00:03:44,000 --> 00:03:50,000
And we'll edit this sketch. Change the angle to about 60.
40
00:03:50,000 --> 00:03:53,000
And because it was outside it's not going to work.
41
00:03:53,000 --> 00:03:55,000
So let's go back into it.
42
00:03:55,000 --> 00:03:58,000
Put it to 45.
43
00:03:58,000 --> 00:04:00,000
And just bring it in.
44
00:04:00,000 --> 00:04:02,000
And it should work this time.
45
00:04:02,000 --> 00:04:06,000
And it does. So you're able to play around with a stiffener like that.
46
00:04:06,000 --> 00:04:10,000
Now let's do one that's on the top. So let's click this top surface here.
47
00:04:10,000 --> 00:04:12,000
Click sketch.
48
00:04:12,000 --> 00:04:16,000
Now we'll click this face here.
49
00:04:16,000 --> 00:04:19,000
Project it out.
50
00:04:19,000 --> 00:04:23,000
And turn it into construction lines.
51
00:04:23,000 --> 00:04:30,000
And let's just draw a little jagged line across.
52
00:04:30,000 --> 00:04:32,000
And we'll go back up.
53
00:04:32,000 --> 00:04:37,000
And we're going to create a stiffener from here.
54
00:04:37,000 --> 00:04:40,000
Now click OK. And click from top.
55
00:04:40,000 --> 00:04:44,000
So now we're able to create the stiffener from the top in this mode.
56
00:04:44,000 --> 00:04:48,000
So let's bring this down to about 5 millimeters for the thickness.
57
00:04:48,000 --> 00:04:50,000
Click OK.
58
00:04:50,000 --> 00:04:53,000
And now we made a stiffener in here for about 5 mils.
59
00:04:53,000 --> 00:04:57,000
So what the stiffener does is we're allowed to just use one sketch, one sketch line.
60
00:04:57,000 --> 00:05:02,000
And you're able to create kind of like a stiffener inside the part that adds like ribs and whatnot.
61
00:05:02,000 --> 00:05:04,000
Now we're going to make one more from here.
62
00:05:04,000 --> 00:05:07,000
So let's just double click on the sketch.
63
00:05:07,000 --> 00:05:09,000
And let's delete these lines.
64
00:05:09,000 --> 00:05:11,000
And let's just try to make an organic one.
65
00:05:11,000 --> 00:05:13,000
So we'll use the spline.
66
00:05:13,000 --> 00:05:17,000
And just make one with a few curves.
67
00:05:17,000 --> 00:05:19,000
And we'll go back up.
68
00:05:19,000 --> 00:05:22,000
And we've created a stiffener with those curves.
69
00:05:22,000 --> 00:05:24,000
So like I was saying, with those lines,
70
00:05:24,000 --> 00:05:28,000
all you need is one line that's open, not a closed profile.
71
00:05:28,000 --> 00:05:36,000
And then you have to toggle between the from side and from top to get the results that you want.
72
00:05:36,000 --> 00:05:42,000
So by doing this, you're able to create stiffeners inside parts quickly and easily just from a single line.
73
00:05:42,000 --> 00:05:55,000
And that concludes our tutorial on how to use the stiffener feature within KTAV5.
