So, this freeform blend is made-up of two separate surfaces because there's a split between two surfaces on its boundary.
00:11
Now, this works slightly differently when we're working with trimmed edges or curves on a surface.
00:16
So, if I open up my Freeform Blend, I'm going to make sure I don't have Chain Select on just to illustrate the situation.
00:23
If I pick all of these edges in a row, which is what I would do with Chain Select,
00:29
and then also all of these ones in the same operation, you can see that it creates a single, freeform blend surface.
00:37
And this is fine for lots of situations, particularly when you're developing your concept.
00:42
But we don't have control as to how these isoparms are flowing.
00:46
So, we have a different way we can work and that is to do each blend separately.
00:52
And for this, we need to pay attention to these edge conditions.
00:55
And most importantly, we need to do a Next to make sure that this one is created as a separate blend surface.
01:03
So again, I'll sort that out to connect ends and I can do my Next or I Pick Nothing as a shortcut for next as well.
01:11
So, in that way, I've created three separate surfaces with flow that matches the way in which I created my curves on surface.
01:22
So, if I keep going on this side, depending on how well your curves on surface match up,
01:29
you're going to need to pay attention to these End conditions.
01:32
I'll do a Next, and that's a small one there.
01:35
So, in this case, Connect Ends isn't giving me what I want, I'll go for Default.
01:40
And again, Default there.
01:43
Not sure what I want here yet until I've built this one.
01:48
Connect Ends there, and I can now go back with the Query Edit and change that one to a Connect Ends.
01:57
So, if you're happy to create a single surface, use your Chain Select.
02:02
If you'd rather control how the connections are made, create them as individual freeform blends.
