- [Instructor] Now that we have our primary surfaces set up
the next step is to create our secondary surfaces.
So we're going to take a look
at the mesh and figure out the next logical step.
It's going to be these blends on either end,
the large blends.
These bottom blends that wrap around
are going to be constructed afterward.
So we need these secondaries here
in order to build these additional blends
across the top and the bottom.
So to frame these out,
I'll sight down the y-axis.
Let me click again to look at the other side.
And I'm going to right mouse click on the compass
and I want to make my privileged plane,
as you can see, z, x.
Now that it's set to z, x,
I'm going to draw in a couple of 3D curves
but I want those curves
to go into these curved geometrical set
so I'll right mouse click here.
Define in Work Object.
Double click on my 3D curve.
And I'm just going to pick a couple of spots above and below
and just eyeball
where this curve is going to go.
Just like that, close enough.
We can always go back and make modifications later.
I'll do the same thing on the other side.
And create that curve.
Select OK and Cancel.
Next thing I want to do
is generate these edges
with curves once again
and to do that,
I'm going to go into the Generative Shape Design.
I'm going to do a couple of intersections.
I'm going to intersect this front
with this end.
And do the same thing.
This end and the front once again.
Cancel out.
And then I'm just going to simply take those intersections
and parallel them
to a location that I need.
So I'll take this curve on that surface,
reverse the direction
and drag it out, get it to the spot
that I need it at.
That looks close enough
and select OK.
Do the same thing on the opposite end.
That curve, that surface, drag this out.
Return this so I'm looking at it from the inside.
And as you can see in this case,
it's a little different in shape,
so I'm going to use a slightly different
parallel curve definition.
I'll just go to Law.
Say Linear.
I'll just shoot this out to 25 for now.
And Preview.
So for this,
I'll come down here.
Go to 20 and take this out to 35.
Take a look at see what we have.
Pretty close.
I need to bring this out a little bit more.
We'll go to 45.
Preview and as you can see,
I can work my way up
into getting that curve right where I need
that curve to be.
And to finalize the curves,
these two that I've drawn out in space,
I'm just going to use project.
I want to project this curve
onto this surface.
The direction that I want to use,
I'm going to right mouse click
and if I look at my compass,
you can see that it's along the y, current.
Preview and there's that curve.
I'll do the same thing.
Right mouse click, y component current
and select OK.
Cancel that out.
Now that I have my curves framed in,
I can put in my blend surfaces.
