Practice exercise

00:01

This is a practice exercise video solution.

00:06

For this practice, we'll begin with the supply data set,

00:08

generative actuator dot F 3D.

00:11

We want to navigate into the generative design

00:13

workspace and begin a new structural component study.

00:17

For this study,

00:18

we need to begin by accessing the connector obstacle in the edit model workspace.

00:23

If you have a pop up that's available for a generative design extension trial,

00:27

you can choose to use this 14 day trial extension to have unlimited solves.

00:31

In this case, I'm gonna close this dialogue and move into the edit model workspace

00:36

at this point.

00:37

We want to take a look at our design and note that there

00:39

are a handful of different areas where we need to have connectors.

00:42

We can see that this design doesn't currently have any hardware,

00:45

but we know that there are several holes in the design that we want to preserve.

00:49

So let's go ahead and begin by using the connector obstacle tool.

00:53

And we're gonna use the start of the shaft

00:55

and the end of the shaft

00:57

to make sure that we determine the appropriate locations

01:00

because we're unaware of the size of hardware in this design.

01:03

We do want to make sure that we include a bolt head

01:06

and I'm gonna increase the bolt head diameter

01:08

until it's slightly larger than the bracket.

01:10

We're going to increase this on the other side

01:12

as well and use tool clearance on both sides.

01:16

We're gonna repeat this process with the connector obstacle noting now that we

01:20

have a connector obstacle that could potentially be obstructed by the first.

01:25

If we add a bolt head, we can see that it just barely clears on both sides

01:30

once again because we don't know what the hardware is going to be in this area.

01:33

We want to make sure that we do account for it in some way

01:36

based on the way the design is set up and the joints in the assembly,

01:39

we note that there is a pivot point here at

01:41

the back location and here at the front location.

01:44

However, these are likely there for structure.

01:47

So we're gonna not use tool clearance on the middle bowl.

01:50

We'll right click and repeat the connector obstacle.

01:54

And once again include bolt heads on both sides.

01:58

And for the last one, we're going to repeat the connector obstacle one more time,

02:03

we want to include bolt heads on both sides as well as tool clearance.

02:08

Once again, we don't know the diameter.

02:10

So in this case,

02:11

we want to make sure that we increase the

02:12

diameters so that we do account for those areas.

02:16

So with the tool clearance,

02:17

we need to make sure that it's large enough for a tool to gain access.

02:20

Potentially a crescent wrench

02:22

for the diameter of the bolt head. We're gonna set this to 35 millimeters and say, OK,

02:28

now that we have these connectors created,

02:30

we also want to make sure that we have a connector up here in the area of the slot.

02:34

This is not going to be done with the connector obstacle

02:37

and we'll need to use some other means of creating these

02:40

to do this. We're gonna simply start a new sketch by right clicking on this face,

02:45

double click the mouse wheel to center.

02:47

This will automatically give us that external profile.

02:50

We can now finish the sketch

02:52

and use the extrude tool to extrude a new obstacle.

02:56

We want to make sure that this obstacle goes to the other side.

02:59

So we'll use the two object option, selecting the backside of the bracket.

03:03

We're gonna make sure that this is a new body

03:06

and we'll say, OK

03:09

at this point, let's expand our model components,

03:12

make sure that we hide all of the other components that we've created

03:15

the ground, the slide nut as well as the load point.

03:19

And then we're going to select the side face of the new body.

03:22

We just created and create another sketch.

03:24

Once again, we'll double click the mouse wheel.

03:26

And in this instance, what we want to do is create an offset.

03:29

So from the modify menu, we'll select offset,

03:32

select the outside profile and we're going to

03:34

increase this a distance of eight millimeters.

03:37

We'll finish the sketch,

03:39

select extrude or press E on the keyboard

03:42

and we'll increase this

03:44

to 10 millimeters and say, OK, joining it with the other body.

03:49

Next, we want to use the create mirror option to mirror that feature.

03:53

We'll select the features, go to the timeline, select our extrude

03:57

and the mirror plane is going to be the center plane of the design,

04:01

we'll say, OK. And now we've created an obstacle for that.

04:04

Once we finish the edit model,

04:06

we'll need to manually select this new extrude as an

04:09

obstacle because it wasn't created with the connector obstacle tool

04:13

at this point. Let's go ahead and make sure that we save the design before moving on.
