I'm gonna show you three ways to tidy the CV layout.
00:06
And I'll start with the Planarize tool and have a look at this rear end.
00:11
There's an Edge Loop option here because Planarize works on edges, not CVs.
00:17
So if I pick those, I get a preview of the plane
00:21
and I can choose here if I want a Z direction plane centered on the selection
00:25
or a Best Fit plane that averages between the two end points.
00:30
But because I want this half to mirror across smoothly,
00:33
I'm just going to check in the side view
00:35
and there's still a little bit of twist there.
00:37
So I'm gonna choose View Based which works best when I'm in Orthographic
00:42
as it's created perpendicular to the view plane and between the two end points.
00:48
And if I zoom in these yellow lines show the Projection Type,
00:52
so Closest moves the CVs 90 degrees to the plane,
00:56
and Adaptive moves them in the direction of the edges.
01:00
So then I can just hit space bar to Planarize,
01:04
and you can see that the subdivision
01:05
isn't green because there's no construction history.
01:08
But because I can pick by edge loop, it's very quick to pick another,
01:12
do a space bar
01:14
and another and a space bar.
01:17
So that does a nice job of making that layout more controlled and regular.
01:22
And we can do a similar job with the Align To Curve tool.
01:27
So let's just say I wanted these CVs to be in a straight line.
01:31
So a straight line here would be degree 1.
01:34
I'm just going to use the simple Align option
01:36
and it's highlighted as the default.
01:38
So space bar will align all of those
01:40
without creating the actual curve or the history.
01:44
And then I can use my Shift to Add-select
01:47
and space bar again
01:50
and again, Shift and Add up to here and space bar.
01:55
So that's straightened out these three sets of edges.
01:59
And then on this hood area,
02:01
I'm going to want curved shapes, not straight lines.
02:04
So I can use degree 2
02:07
and I'll pick from here and Shift-Add to here
02:11
and then just do the space bar to Align
02:14
and I can select again
02:16
and space bar
02:18
and again,
02:20
and that does a really quick tidy up.
02:23
And the key really is to understand the
02:25
effect of different degrees on a curved shape.
02:30
So then finally, I've got a Smooth tool
02:33
and this has got two modes, Smooth and Relax.
02:37
So I'll start with Smooth and keep this Strength value reasonably low.
02:43
And then I just click and hold and drag
02:45
across faces to reduce the angles between the edges
02:49
and smooth out some of these zigzags.
02:52
And again, there's no history but the Undo works well
02:56
and I can reduce this Strength value
02:58
and then do it again more iteratively this time with a bit more control.
03:05
And if I do a Smooth on this middle section here,
03:07
it will soften that inwards, but it doesn't really change the layout much.
03:13
Whereas if I now switch to Relax and do the same thing,
03:17
then it does the same smoothing. But it also changes the edge lengths
03:21
and moves towards a more even distribution
03:24
which changes the layout quite significantly
03:28
Over here, if I use smooth it
03:31
improves the layout, but I've still got this angle here.
03:35
So I'll do an Undo
03:36
and this time I'll use Relax
03:40
and I get a nicer layout.
03:42
But if that's too much, I can do Undo again,
03:45
reduce the Strength
03:47
and then just do a series of small click and drags to get a more subtle result.
03:54
But be aware that even in Smooth mode, you can lose too much of your design shape,
03:59
particularly in the interior.
04:03
And with Relax, the effect is even stronger.
04:06
So to avoid losing too much of your original work, then keep a low strength value
04:11
and just use Undo if you go too far.
