Create patterns

00:03

Create patterns.

00:05

After completing this video, you'll be able to create a rectangular pattern,

00:09

a circular pattern and a pattern on a path.

00:13

In fusion 3 60 we want to begin by taking a look at the supplied data set patterns

00:19

inside of this data set, we have three bodies and in the sketches folder,

00:22

we have a sketch called path.

00:25

We're going to be taking a look at creating

00:26

patterns and we're going to be looking specifically at feature

00:30

and face patterns in this design as well as doing a body pattern on a path

00:36

to get started. We're going to be looking at rectangular patterns

00:39

and it's important to identify how specific things were created.

00:43

So for example, if I select this face in this cut out,

00:47

notice that it highlights a feature in the timeline.

00:50

This shows me that I have a sketch

00:52

and that I have a feature that was created.

00:55

Also note that I have a hole here and the hole was created with that whole feature.

00:60

This is going to be important as we begin creating

01:02

patterns and determine what our selection process looks like.

01:05

So to begin, we're going to select rectangular pattern and similar to sketching,

01:10

we have multiple type options that we can toggle back and

01:14

forth between depending on which pattern we want to use.

01:17

The first thing that we're gonna be looking at is rectangular pattern of features.

01:22

I want to begin by selecting the feature in the timeline

01:25

and then the axis uh I'm gonna select the X axis or one of these linear edges

01:31

and then I want to begin dragging this out

01:34

as we get a little bit further.

01:36

I do want to take a look at the extent I can change this to a spacing option

01:41

which will dictate the amount of space between each of the objects.

01:44

I'm gonna set this to 38 millimeters, change the direction to symmetric

01:48

and increase the number to five.

01:51

Once I say OK, this is going to allow me to add those details to the design.

01:57

I'm gonna repeat that process with a rectangular

01:59

pattern once again doing features but selecting the whole

02:03

the axis once again is going to be the X axis.

02:06

So I'm going to hold down the left mouse button,

02:08

make sure that I select X and begin dragging this out.

02:12

Once again,

02:13

I want to use spacing and I'm gonna set this at the same spacing for 38 millimeters,

02:18

change this to symmetric and increase this to a number of five.

02:23

This allows me to add the holes at the

02:24

exact same spacing that I did the original pattern.

02:28

Now even though this original feature was created,

02:31

I am able to use the pattern as well as

02:34

the original feature in other tools like a mirror.

02:37

So if we select mirror,

02:39

change the object type to features,

02:42

if we select the first pattern

02:45

and the mirror plane, this is going to be our XZ plane.

02:50

Notice that it emits the middle object

02:52

under objects, we need to go back and also select the original extrude.

02:57

And that original extrude is going to be added to the selection.

03:00

That way we're patterning all of the separate pieces.

03:04

So keep in mind that the patterns are not

03:06

going to include the original or the seed feature.

03:09

If you decide to do something else like another pattern or a mirror,

03:13

let's hide the rectangular pattern and let's

03:15

focus our attention on the circular pattern.

03:18

When we take a look at the circular pattern, it highlights this as its feature.

03:23

But you'll note that the hole was actually created

03:26

as the original feature inside of that extrude.

03:29

This means that if I go to create a pattern based on the feature,

03:32

it's not going to work.

03:33

What I want to do instead is take a look at using a circular pattern

03:38

and change my object type to faces.

03:40

I'm gonna select the inside face for my axis. I'll be selecting Z

03:45

and I can use the onscreen manipulators to drag and add more or less holes.

03:50

We're gonna set it to eight instances

03:54

and we'll say, OK.

03:55

So even though the original hole was included inside of that first sketch,

04:00

we were able to pattern its face,

04:03

you can see the small tooth cut out is actually an extrude.

04:07

So we can use the circular pattern of that feature.

04:10

If we preselect a feature,

04:12

it'll default to a feature object type with it already selected.

04:15

We just need to pick the axis of revolution

04:18

and then begin increasing it until we have the correct number.

04:22

For this example,

04:23

I'm gonna go all the way to 50 instances and note that we get a warning

04:27

at some point, you'll be adding too many instances.

04:30

And there is a fear of the calculation time.

04:33

How long it's going to take for it to compute?

04:35

This is a fairly simple extrude so I can take this up without fear of the calculation.

04:40

But just note that it is going to take a little bit longer.

04:44

If it's trying to adjust each instance,

04:47

we're gonna change the compute type option to optimized and say, OK,

04:52

so this allows me to add that feature and it does do away with that warning.

04:56

Keep in mind when we use those options, like adjust, optimize and identical,

05:01

they will have varying degrees of effects based on the input selection.

05:05

So in this case, it really didn't have much of an effect on the final geometry.

05:09

However, it did affect the compute time.

05:12

So if you're having a pattern with a large number of instances,

05:15

consider checking out the other options.

05:18

The last thing that we want to do is take a look at the path

05:21

and the path body

05:23

we're gonna be using once again a pattern, we're gonna be using pattern on path.

05:28

And this time we want to take the bodies as the object type,

05:32

the object is gonna be this solid body and

05:34

the path is going to be this sketch selection.

05:37

As we begin dragging this out,

05:39

we want to make note of what happens to these as they roll around the corner,

05:44

I'm gonna begin increasing the quantity.

05:47

And for the distance, I'm gonna set this as

05:50

going all the way to the end. So we're gonna pull it all the way to the very end

05:55

and we'll increase this to a number of 10.

05:58

Now,

05:59

you can see that the original orientation of the body and the final orientation

06:03

of the body appear to be the same as we rotate this around.

06:07

You can see that they're in the same orientation.

06:10

Now, this could be the intended outcome and it could be perfectly fine.

06:14

However, we can change some of these options, for example,

06:17

change it to path direction.

06:20

This means as the object gets rotated around

06:23

the orientation of the original body relative to the path

06:27

is going to change

06:29

as it goes around that design.

06:31

Uh this can be extremely handy,

06:33

especially if there are elements of your design that do need

06:35

to rotate and change as it goes along the path.

06:38

This would also work for things like feature and face patterns.

06:42

But in this case, we're just looking at patterning an entire body.

06:46

If we toggle on the suppression option,

06:48

this gives us check boxes which allows us to toggle

06:51

on or off certain entities inside of our pattern.

06:56

So for example,

06:57

if I wanted to turn some of these off and I only

06:59

wanted ones that were closer to the center of the corner,

07:03

then we can toggle them on and off as needed,

07:06

gonna leave two right in the middle and say, OK,

07:09

at any point in time, just like with any other feature, we can double click and go back

07:13

and make changes,

07:14

bringing back some of those others that we already suppressed or

07:17

we can turn off the suppression option to bring them all back

07:22

at this point. Let's go ahead and hide the path sketch,

07:25

go back to a home view and make sure that we do save this design before moving on.
