- [Instructor] So now I have the bosses in the model,
but I don't have the bosses in the core.
The core cavity method is very conducive
to building the actual tool
that's going to be used for the coring process.
So when I put the bosses in,
I don't necessarily add them to the main body.
What I do is I go to the body that's generating the core.
Now if I take a look at this,
I'm just going to right mouse click on this
and say Define In Work Object,
you'll see here this is the actual core body, okay?
The initial close surface that's being used
for the cavity, if I Define In Work Object on that,
you can see the large radii.
What's happening is the core is
removing the actual volume from
the back of the part to define the B side.
Now what I have is a visualization tool turned on
so that when I look at the individual body,
all I see is that one solid volume.
So if I come down here
and hit this little arrow under CurrentBody,
you'll see I have this tool right over here.
What this does is it shows only the current operated solid.
If I turn that off, you'll see both solids.
If I turn that on, you'll see just the one solid.
So this is a little switch
to help you visualize those individual bodies.
I'm going to turn it on, so I just see the one body.
At this point, the core body is my active or in work object.
So I'm going to take these bosses
and remove those from my core body.
Once I do that, go ahead and turn off my visualization,
you can see there's my core body.
What's going to happen is this is removing from this body.
Because it's removing from this body,
it's going to change or affect the initial remove
that I did for the actual coring process.
I'm going to right mouse click on Remove 1,
Define In Work Object, and now you can see
those bosses are shown on the main body.
But I didn't add them to the main body, per se.
I have them on the main body by
removing those from the coring process.
So think of the coring process as
removing all that material on the inside.
So the coring process, I'm telling it,
to only remove the material that I want to remove.
So again, this is going to actually mimic
the final tool that's going to be used to make the part.
So that is sort of the core cavity methodology.
If I go back up to the part body, right mouse click,
and say Define In Work Object,
you can see I have that split
now added back in for my interface.
Once again, if I look at my tree,
you can see there's my main body up here,
CloseSurface1, and this is the core body
with all of the additional features
that I'm using to remove from my cavity body.
