- [Narrator] Now that I have my dieline in place,
or my tooling direction, next thing I need
is a parting surface, or parting element.
This could be a line.
Often times, the styling department
or an engineering department's going to provide
to you where the parting element is going to be.
The parting element basically defines where
the tool separates.
So, again, this is an injection molding.
That means I have a cavity and a core,
so basically two halves come together.
Where do the two halves separate?
So we need to define that.
There's a couple ways that we can do that.
One method is to use an extrapolation
and another method is to untrim the original surfaces.
So it could be a dance between using both.
You may be able to get away with using one method
or coming through and untrimming a surface
and then extrapolating it because you need
a larger parting element.
So it's up to the actual part,
the requirements for what you need
to do to get it to go.
Now, I'm going to go
into my tooling set under construction geo,
right mouse click, and say define in work object.
Just to show you the extrapolation method,
this isn't the final method,
but just to show you where it's at,
I can go into the extrapolation tool.
I can pick my boundary.
I can specify a length, the type of extrapolation
that I want to create.
I'm going to change this from propagation mode
from none to tangent.
Switch that back, and it creates this ribbon
all the way around the part,
based off of the link that you defined, okay.
Now, it's important that you pay attention
to what's going on with that ribbon
because you may end up with odd little things
at certain points, again depending
on the quality of the surface that you get,
you may get crisscrosses at these boundaries,
so just pay close attention to what's happening there.
And once I'm done with that extrapolation,
I can take that and offset to get my parting surface.
In this case, I'm not going to do the extrapolation,
I'm just going to cancel.
I am going to use the untrim.
I select the surface, and simply select okay.
In this case this is a single pad surface.
Because it's a single pad surface,
it returns to its original, untrimmed, shape
and size as you can see.
Now I'm going to use this to offset
from for my parting surface.
So I'm going to right mouse click on tooling,
I'm going to say define in work object
'cause I want to put the parting surface
at the same level as the initial dieline
within my organizational structure.
So for my parting surface, I'm going to come in, do an offset.
Make sure it's going in the correct direction.
Reverse that.
Go the distance that I need.
Hit enter.
And because it's a parting element,
it's a driver of sorts.
For me, my own preference again, is to change the name.
We'll go into properties.
And then also same with the graphic.
I like to give it its own special,
unique graphic properties.
So, for this I'm going to come in here.
Change the color and update the transparency as well.
Select okay, and there is my parting surface.
