Create a 3D model solid trigger

00:02

Create a three D. model saw trigger.

00:06

After completing this video, you'll be able to use extrude.

00:09

Use fill it and create a drafted part

00:13

Infusion 3 60. Let's carry on with our trigger model from the previous video

00:17

we want to make sure that we activate the trigger

00:20

and we're going to make an adjustment to the sketch.

00:22

We'll double click on sketch one,

00:24

double click our mouse wheel and we want to change the

00:26

overall length of the push portion of the trigger to 20 millimeters

00:31

From here.

00:32

We're going to finish the sketch and now we want to turn this into a solid body.

00:36

Apart like this is created using

00:38

injection molding and injection molding requires parts

00:41

to have draft on them so they can be removed from the mold.

00:44

Once the plastic cools

00:45

in order to do this, we're going to make use of symmetry.

00:48

And the extrude features taper option.

00:51

So to get started, let's select extrude.

00:53

And we want to begin by selecting the large portion of the trigger,

00:57

going to rotate this around so we can see what's happening.

01:00

We're going to use the symmetric option

01:02

with the whole length set to 20. We also want to include at least one degree of draft.

01:09

When I select one degree of draft by default, it's gonna draft outward.

01:14

If we view this from the front, you can see that it's tapering out and it looks like a v.

01:18

We need to make sure that this is in the negative direction for this example.

01:22

This means that the parting line will be right down the middle

01:25

and it will be able to be pulled from either side.

01:29

Once we do this, let's select. Okay,

01:32

now,

01:33

an important note that we need to consider here is that when

01:35

we showed the sketch again and we extrude this out with draft,

01:39

These two objects are no longer going to connect.

01:42

So this means that we need to extend this profile inward to do that.

01:46

I'm going to edit the sketch

01:48

double click the mouse wheel

01:50

to fit to screen and use my line tool

01:53

with my light tool. I'm going to extend this inward

01:58

and make sure that I have a little bit more of this profile.

02:01

Using d on the keyboard. We're going to add an aligned dimension

02:06

of four millimeters

02:08

Notice that it's still under defined. It's under defined because this four

02:13

is floating around a bit.

02:15

We need to make sure that these lines are perpendicular

02:18

with this edge or co linear with this edge.

02:20

We also want to make sure that the upper and lower portions are also equal.

02:25

If you have any issues with this is a chance that your dimension value

02:29

is going to be referencing the wrong point.

02:32

So let's try the dimension again.

02:34

This time I'm going to select the end face and this

02:36

face here giving it an overall dimension of 24 mm.

02:40

So it is important that we make sure we are selecting valid

02:43

references that aren't able to move around when we're applying our dimensions.

02:47

Let's finish the sketch

02:48

and now let's create another extrude

02:51

This time. We need to hold down the control or command key to select both profiles.

02:56

We're gonna change this to a symmetric with the whole length set to four.

03:01

Notice by default, it's trying to remove material

03:04

and that's because part of our profile overlaps a solid body.

03:07

However we wanted to join.

03:09

We also want to make sure that we include that same negative one degree of draft.

03:14

The main reason that we needed to extrude that profile is to

03:17

ensure that we don't leave a gap between these two faces.

03:20

We're going to say okay.

03:22

And then we can hide our sketch.

03:24

What we should see from here is that when we look at our design from the side,

03:27

all faces should be visible.

03:29

We can see the top face here of this trigger portion,

03:33

We can see this face here and as we rotate this around,

03:36

that should only be the face from the parting line toward us.

03:39

This is a basic understanding of how the draft is going to work in your design.

03:44

Now that we've applied the draft to the midline.

03:47

We can go ahead and add some filets, we're gonna go to modify,

03:50

fill it and we're gonna start with these large spline edges.

03:54

We're gonna begin dragging this in and I want to add a relatively large,

03:58

fill it in this case seven.

04:01

Note that we can add multiple filets to a single feature,

04:05

but they're not going to take into account the

04:07

rounded geometry that you get from that first,

04:09

fill it.

04:10

So if you want to add additional filets,

04:12

it's a good idea to consider the way in

04:14

which your model is being built for this example.

04:17

I'm not going to add the secondary

04:19

but I do need to select an edge since I already selected to add a new one and say okay

04:24

from here, we're going to add a few more filets.

04:27

I'm going to select this back edge to fill it and notice that it

04:30

doesn't carry on to the other side because we don't have tangent see.

04:33

So I need to select both sides and then I need to bring this down.

04:37

I'm going to add a 2.5 millimeter radius here and say, okay,

04:41

what's important is that when we view this from the side we

04:43

still are seeing up to that parting line and not selecting across.

04:48

So everything looks okay there.

04:50

We want to add a few more filets.

04:52

I'm going to repeat the,

04:53

fill it and this time I'm going to add it to

04:55

all of the long edges of the trigger actuator portion.

04:58

I'm going to give them a one millimeter, fill it

05:03

from here. Everything looks okay. And I'm going to add one more fill it

05:07

And to select this edge and this edge here, adding a one

05:10

Philip

05:13

and once again viewing this from the side to make sure

05:16

that we are only seeing up to the parting line.

05:18

So if you zoom in and select this face, you can rotate around and we can see that

05:24

everything here looks pretty good.

05:25

And one final step that we could do is use inspect and draft analysis.

05:29

We need to select the body of interest and then we need to select

05:32

the pull direction which is going to be a right plane or a midline.

05:36

We're going to turn off the tolerance zone and we also want to

05:39

make sure that we take a look at the draft angles being used.

05:43

Remember that we set ours to one degree.

05:45

If we set this to one degree it'll show us up to and including one degree.

05:50

If we reduce this down to half a degree,

05:52

we should see that everything is either green or blue

05:56

because this is going to go directly up to that one degree amount.

06:01

Any draft that's exactly one degree will show up

06:03

in that red color or the yellow color.

06:06

What we wanna do here is we want to take this 2.99 on

06:11

both sides or 0.95 and just ensure that we do have enough draft.

06:15

Once again,

06:16

if we go all the way up to one degree in

06:18

the negative direction or one degree in the positive direction,

06:21

it is going to show this marbling across there,

06:26

everything looks okay for our draft analysis. So I'm happy with that part.

06:30

I'm gonna activate the top level of our design,

06:33

go back to a home view and make sure that I saved before moving on.
