- [Narrator] In this next exercise,
we're going to be creating additional elements
that are going to be used to split this main slab.
So I need to create references
that are based off of not only the main slab,
but some of the original elements that I've also created.
Now, the elements I am going to generate
are going to be used for splitting purposes,
and as you can see, we have a geometrical set
already set up in the tree.
Here I'm going to right mouse-click
over the splitting elements,
I'm going to say "Define In-Work Object".
Now this does two things.
Not only does it make the geo set the in-work object,
but it also shows it, because before it was hidden,
and as you can see,
I already have an element in there for you.
Now, when I go and I generate
some of my new reference geometry,
I want to try to reference the original base elements
of these surfaces.
As you can see, I have this flange.
The first part is, I'm going to take and offset
the initial surface that made this flange,
cause I want to create a splitting object
that comes out in this area.
So, easiest way to find this base element,
I know this is a small model,
you can go back and pick it right out of the tree,
but when you're dealing with a large model,
you have to understand how to navigate,
and this is where the quick-select comes in very handy.
I'm going to pick one of the faces on that,
you'll see slab two, and I'm just going to
right mouse-click on "Hide/Show".
Select "Okay", and that gives me that initial surface
that I had created.
With that, I'm going to offset this initial surface,
and I'm going to reverse the direction.
How far do I want to go?
Now you can drag this, get it out to where you need,
say 85 millimeters, or you can just simply
enter in 85 millimeters.
Select "Okay", there's my initial surface.
Now, with, that, I'm just going to right mouse-click.
I'm going to say center graph so I see where that offset's at,
you can see it's inside that splitting element.
And temporarily I'm just going to hide it.
Next thing I need to do is I need to extract this top edge.
With that, I'm going to go in and do an extract,
and I'm going to pick this edge here,
propagation type is tangent continuity,
and what it's going to do is it's going to run all the way down
and stop at that point.
The reason why it stopped at that point
is because that's technically a vertex.
And because that's a vertex, that is a hard point,
and I'm asking it to find
the angular continuity,
and at that point is a point continuity.
So I'm just going to select "Okay",
and then I'm going to extract this edge
and you see it stops at the same point,
select "Okay", and I'm going to cancel.
Now that I have that, I'm going to go in and do a join.
Select my join, I'm going to pick this curve and this curve,
select "Okay", and as you can see, there's my join.
Extract one and extract two are now hidden away.
Now that I have that, I'm just going to do a parallel curve,
I'm going to parallel this curve,
and it needs to sit on the surface,
the surface it's going to sit on,
and I'm a big fan of using the references
that are the most stable,
which are, again, basically the first
or the parent element of things.
So in this case, I can pick this back flange,
reverse my direction, and go up
a few millimeters, and select "Okay".
You zoom up on it a little bit,
now I can hide that join.
I can also now hide that surface.
I'm going to go back into my tree,
show my offset, and these are the elements
that I need to split this part out.
For that, I'm going to come in,
insert geometrical set, and call it split.
Once I have my geo set, I'm going to right mouse-click,
go into properties, and then again,
change the colors of the surfaces.
Now, when I'm doing actual production work,
I typically use purple for my splits.
It's just my preference. You pick yours. Run with it.
Some companies will have their own preferences
for those as well.
I'll go into the split function,
I'm going to select this surface,
I'm going to pick the elements I want to split to,
that parallel, that plain, that offset.
Select "Okay", and now
I can just go into my splitting elements,
select them, pick one, hold my control key down,
pick all the other elements, and then just hide those.
And as you can see, there is my main split surface
that basically creates my sheet metal part.
