- [Instructor] Now that I have my curve frame in,
I'm going to go ahead and create my secondary surfaces,
the actual surfaces through those curves
and for that, I'm going to go into Blends,
right mouse click, Define a New Work Object,
and use the Blend Operator here
in Generative Shape Design.
I'm going to go from this tangency
to this surface, this tangency, to this surface,
and I want to make sure this has curvature.
Hit Preview and there is my initial blend.
If doesn't quite match up to the scan,
you can go into tensions
and increase the tension a little bit
or decrease the tension a little bit
and what this is going to do
is going to give you a little more crown to the surface
and Preview,
select Okay
and do the same thing on the other end.
Here's my curve, surface, curve, surface,
go to Tensions, everything's still the same.
Preview, looks pretty good
and hit Okay.
At this point, I'm just going to do a quick
distance analysis.
So I go down to my Distance Analysis,
it's at the bottom of the tree, I'll show that.
I'm going to double-click on it
and my source is the surface.
My target is this mesh
and as you can see, it deviating kind of far
so, with that, I'll double-click on that blend,
go back into my tensions,
and I can begin modifying those,
Preview, to get this closer
to the shape that I need.
And as you can see,
I'm getting pretty close to that scan,
just by modifying these tensions.
I'm less than half of a mil, select Okay
and do the same thing for the opposite end.
I'll just double-click on my distance analysis.
Source is this blend,
target is the mesh,
this one's much closer,
so just double-click on it,
go back into my tension,
and decrease that tension, preview,
and, again, we're below half a mil,
so everything looks good.
We'll leave it alone, select okay
and we'll call our secondary surfaces done.
