As the design develops, you'll end up with more CVs
00:06
and in wireframe, the ones in the distance and the foreground are all visible.
00:11
And so if I do a box-select,
00:14
I kind of expect to select these ones at the front and these ones behind.
00:20
But that becomes more of an issue when I'm using box mode
00:23
because I don't see the CVs behind the shading.
00:27
So it looks like I've done a controlled selection.
00:30
But in fact, I've accidentally selected these ones behind.
00:36
It's not so much of a problem in surface shading
00:39
because I can see the obscured CVs
00:42
and that's due to this Xray setting that gives them a partial visibility,
00:47
so you can see them,
00:49
but you're still at risk of selecting them.
00:53
And that's why we have this icon up here for Camera-based Selection.
00:58
And when that's on, a drag-select won't select the ones behind.
01:03
The shading occludes the selection.
01:06
And that works for box mode shading too.
01:09
And this icon is a shortcut for the Preferences > Selection Options here
01:14
and it defaults to just Shaded occlusion,
01:17
but I can choose to use both Shaded and Wireframe.
01:23
So then without shading,
01:25
I still have the occlusion effect for the selection
01:28
even in the wireframe.
01:30
And I can always toggle that off and switch back to being able to pick through.
01:36
And it's worth keeping an eye on that setting so
01:38
that you always get the behavior that you're expecting.
01:44
Another way of managing lots of geometry is selection sets.
01:48
So let's say I want to select this hood
01:50
and I can use the Grow tool here to get the faces that I want.
01:55
Then if I want to pick that often,
01:57
I can come up to the Edit menu and create a selection set from it.
02:01
And there's a couple of options, but I'll just take the default setting and say go
02:07
and then here on the Windows menu, I've got the Selection Set Lister
02:11
and I can rename the set here if I want to.
02:15
And if I do a Pick Nothing, then on the palette, I've got a Pick Selection Set tool
02:19
that'll pick the whole set with just one click
02:23
and a set can be surfaces, curves, faces, CVs or a mixture.
02:29
So here I can pick this line of CVs
02:32
and create another selection set
02:35
and I can rename it here.
02:39
And when I use Pick Selection Set,
02:41
I need to click on a member of that set,
02:43
so a CV, in this case.
02:46
I can't just pick on the edge of the hull to select it.
02:50
Alternatively, I can pick it using the entries in the Set Lister.
02:56
So if you're going to use selection sets,
02:58
it's probably worth adding the pick tool to your marking menu.
03:03
And another tool that some users also add is Pick Hull
03:07
because picking SubD elements and CVs can be a bit confusing.
03:12
So here if I use Pick Edge, it actually does two things.
03:15
It selects the edge which I use for SubD tools like Bevel or Crease.
03:21
But also when I do a transform CV, it selected the two CVs associated with that edge
03:29
and Pick Face has the same two selections,
03:32
the face object for tools like Extrude or Extract,
03:36
but also the four CVs on the corners for Transform
03:42
and the same for edge loop,
03:44
I've got edges
03:46
but I only see selected CVs when I activate the Transform CV tool.
03:51
So if I want to pick those CVs first, I can use Pick Hull instead
03:56
and it selects the same range
03:58
but only the CVs not the edges.
04:01
And for some tools like Align up here,
04:04
that's what's required.
04:08
And then just a final tip is to explore
04:10
these different settings for the three mouse buttons,
04:14
they're fully customizable. But there are four options for only three buttons.
04:19
And the one not in the default settings is Pick,
04:22
so I'll show you that. And I'm going to put that onto my middle mouse button
04:26
and then put add back on to the left because it's so useful.
04:30
And that just means I no longer have the toggle option.
04:34
So then if I pick some faces
04:37
and then I want to pick over here instead,
04:39
previously, I'd have to do a Pick Nothing first,
04:43
but with the middle mouse button, I can just pick this one instead
04:47
and then use the left button to add
04:49
and add again
04:51
and I can use the right button to unpick.
04:55
So that pick option just means I don't have to use
04:58
Pick Nothing to go and pick a completely different item.
05:02
So there's no right or wrong for these.
05:04
It's just up to you to explore the settings and see if they suit you better
05:08
or to just keep the default settings if you're used to those.
