- [Instructor] Now I need to set up some references
for some bosses in my ribs.
The bosses are going to be used for mounting purposes
and the ribs are used for stiffening purposes.
To do so, I need to be back in Generative Shape Design.
So I'm going to switch back over.
Now that I'm here,
I'm going to insert another geometrical set,
and again give it a name.
Something descriptive that you know what it's for.
Call it bosses, ribs.
To position my bosses
and my ribs,
along with the styling data we got these mounting points.
Often times, you're going to get these points
for specifically mounting.
Again,
you may have something to touch or clear.
You may get a plane,
so that styling import's very important.
To make sure you get all your data across.
Now you'll see I have these three mounting points.
For my positions, all I'm going to do is
generate a couple of axes
so, we'll double-click on the axis system.
The first one, I'm going to give it an origin
this location,
My X
axis is going to be based off of
the original X axis
and then for my Z axis,
I want to make sure I use the die line.
You'll see it wants to reverse it
and all I'm going to do
is just hit reverse over here to point it in the
direction that I want.
Now, for this one, I don't want it to be current
nor do I want it under the axis system node
I want it to appear inside of this
geometrical set for bosses & ribs.
So I'll turn that off and you'll see here
it wants to put it there.
Select okay.
Now I'm goin' to do that one more time.
I'm just simply going to pick
This point,
X axis.
Come over here, tell it Z-direction.
Otherwise its going to pick for Y, we don't want that.
We want Z, once again I have to reverse that and select okay
and from there, just cancel out.
Next thing I need to do is generate
a surface
for
my rib heights.
Now, to do so, I am going to go in and create an offset.
What am I going to offset off of?
I'm going to offset off of the initial un-trimmed surface
or the surface that you may have used in extrapolate off of.
Reverse the direction,
and now how far do I want the offset to go?
So once again, I'm going to create a formula
I'm goin' to right-mouse click, edit formula.
go to rename parameters.
I want to go to
twice the thickness.
So that means the rib when its created
is going to be at least the material thickness
tall,
off of the backside.
So we'll just say times two.
And ,as soon as I select okay,
you'll see, it gives me that surface!
Last thing I want to do is, again I want to give things a name
I want to make sure that people know
exactly
what it is I'm doing, so I'm going to go to the offset,
I'm going to right-mouse click, go into properties,
feature properties and
give it a
descriptive name.
And like that, we have all of the necessary data
to create our bosses and our ribs!
