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.
