So typically we'll use Skin to just connect to input sets, but we can use it to connect as many as we like.
00:08
So the first two selections will create the first straight line skin,
00:13
and then if I want to add more and blend between them, I need to use the Shift key.
00:17
So if I Shift and hold down and keep selecting,
00:22
you can see that a single skin surface is being blended between all of those selections.
00:31
Now, if I forget to add some curves in there, I can do a query edit and go back in,
00:38
but I can only select curves that come in the right place in the sequence of selections.
00:44
And I also need to use the Shift key again, so I'll Shift connect that one and Shift connect that one.
00:51
So we don't use this very often because the blending can be unpredictable and a bit difficult to control, but it can occasionally be useful.
01:01
You'll generally get better results with fewer curves
01:05
and also if those curves are very well matched in terms of their prioritisations and CV layouts.
01:11
So again, the first two creates the straight lines again as you'd expect, and then the Shift key to connect the third one.
01:20
And of course we've got construction history, so we can use in this case that center curve to shape and modify the surface.
01:31
Another situation where working with three curves works well is across a center line, like on this windscreen.
01:39
Now my curve is using layer symmetry to create the mirrored copy on the other side,
01:45
and it is possible to use this in creating a skin between three inputs, and it works quite well initially.
01:53
So if I turn those CVS on there, move those up and down, you can see that that's updating.
02:00
But this is not very reliable.
02:03
For example, if I turn off the symmetry on my curves layer, it tells me I'm going to lose the construction history on that surface.
02:11
So now there's no updating and connection between the curves and the surface.
02:16
And that break in history will also happen if you save the file and then open it back up again.
02:22
So more typically, we'd take a mirror of that curve and then do a standard skin between those three curves.
02:32
And then just be careful to make sure we pick them equally on either side when we want to do any changes.
02:41
So don't forget to use the Shift key for the third input set.
