We'll get started with the supplied data set trigger model dot F three D.
00:10
This design was created as a solid part and can be pulled in the X direction.
00:15
We're going to be creating a core and cavity mold for this part.
00:18
And we'll get started by first creating a sketch.
00:21
The sketch will be placed on the Y. Z.
00:23
Plane and we need to create a box that's
00:25
large enough that can encompass the entire trigger.
00:28
So we'll create a box and in this case we're going to make the box 50
00:32
tall and we'll make it 100
00:35
wide.
00:36
We want to get it roughly centered while it's not strictly required.
00:39
We do want to get it close and we'll add some dimensions.
00:42
So that way we can place it relative to the design
00:46
at a 45 millimeter dimension to the right from the origin
00:50
and we'll add a 25 millimeter dimension to the top from the origin
00:54
and finish sketch.
00:56
Next we use extrude to create a box that can completely encompass the design.
01:01
One thing that we can do here is we can use the intersect option
01:04
and make sure that we are seeing the entire design inside of this box.
01:08
And once we're happy with the overall dimensions,
01:11
we're going to say that we want to create a new body or a new component
01:15
in this case. We'll use the new body option
01:18
Before I go any further. I'm going to expand the bodies folder,
01:21
right click on body one and change the opacity
01:24
to 30%. So I can see inside of the design
01:28
from here. We're going to go to create boundary fill and we want to select the tools.
01:35
In this case we're going to have the main body which is going
01:37
to contain our mold and we also want the body of the trigger.
01:42
Next we want to select the cells and notice that there are two boxes here.
01:46
We want to select the box that represents the overall mold itself.
01:51
And we want to make sure that we find the correct box.
01:54
This is going to represent the center of origin of that component.
01:57
We want to create a new body and we're not going to use the removed tools option.
02:01
We're simply going to say, okay,
02:03
so notice that we have two bodies. Now if we hide body too,
02:07
we're left with body one and if we hide body one, we're left with the trigger inside.
02:12
Let's hide the trigger component
02:13
will show body to
02:15
right click and change its opacity to 30%.
02:18
We can see now that there is a cavity inside.
02:22
The next thing that we need to do is split this at
02:24
the parting line because the part was designed about the origin.
02:28
This is a relatively straightforward process by using the split body tool.
02:33
The bodies to split will be body too
02:35
and the splitting tool, we can use one of our planes
02:38
will hold down the left mouse button and we'll make sure that we select the Y. Z.
02:42
Plane, allowing it to extend and say, okay
02:46
Now you can see that we've got both sides of our mold. I'm gonna call body to Mold B.
02:52
and body three mold a
02:58
body one should be a solid original version of the design.
03:02
You can see that this is simply a rectangular
03:05
body that does not have the core removed.
03:08
Now you can see that we've got mold B. And mold A.
03:12
Because we no longer need to see inside of these.
03:14
I can go back to opacity control and set it to 100% for both mold a. And Mold B.
03:22
Now that we have these designs.
03:23
Another step could be to use inspect and draft analysis to
03:27
make sure that we don't have any problems with draft.
03:29
Under design
03:30
the direction will be this and I'm going to go
03:32
ahead and set my values down to half a degree
03:37
and make sure that everything on the inside is green.
03:40
You can see there are some areas here where some of the draft starts to turn yellow,
03:44
which means that we have a tolerant zone.
03:46
Let's go ahead and turn that off and make sure
03:47
that all the areas are green on the inside.
03:50
Everything looks good from here. I'm going to select, cancel
03:54
and make sure that I do save the design before moving on
