Create and modify Three-D surface features.

00:06

After completing this video,

00:07

you'll be able to

00:08

create surface features,

00:09

create a solid from a thickened surface,

00:11

and use stitch to combine surfaces.

00:17

In fusion,

00:18

we want to begin with the supplied dataset surface sample.

00:21

F3D.

00:22

To begin,

00:23

we want to show sketch one and navigate to our surface tab.

00:27

In our services tab under the Create menu,

00:29

we've got several tools that are similar to our solid Tool counterparts.

00:32

Extrude,

00:33

Revolve,

00:34

sweep,

00:34

and Loft all behave very similarly to how they do in the Solid tool set.

00:39

However,

00:39

we also have tools like patch,

00:41

ruled,

00:42

and offset that are unique to surfacing.

00:45

Let's go ahead and take a look at a few of these.

00:47

First,

00:47

the Extrude tool.

00:49

With the Extrude tool,

00:50

we can use a closed profile just like we do with a solid.

00:53

However,

00:53

this is always going to create the outside profile.

00:56

If we instead turn off chaining,

00:59

we have the ability to extrude just a single edge.

01:02

We can manually select multiple edges

01:04

and continue to add edges to our selection while we're creating these extrudes.

01:10

In this case,

01:11

using the extrude surface tool will require us to

01:14

do additional operations to convert this to a solid,

01:17

whether it's adding more surfaces,

01:18

patching,

01:19

and stitching the ends,

01:21

or by using the tools like thicket.

01:23

In this case,

01:24

let's go ahead and cancel the extrude and take a look at the revolve tool.

01:28

Once again,

01:28

the revolve tool will behave very similar to

01:31

how it behaves in our solid counterparts.

01:33

We can use a closed profile and create a revolve.

01:37

However,

01:37

while this does look like a solid,

01:39

it is going to be a thin part.

01:41

Let's go ahead and cancel the original selection,

01:44

disable chaining,

01:45

and this time select a single edge.

01:48

We can see here now that as we can

01:50

create a revolve with either closed or open profiles,

01:53

doing this with the surfacing tools will not produce a solid body by default.

01:58

We have all the same options,

01:59

such as a full or partial revolt.

02:02

We can also change the angle of it,

02:04

determine whether it's going to or from an object,

02:07

and all the same settings that we have at the solid level.

02:10

However,

02:10

we are able to do this with open profiles and surface tools.

02:15

Once again,

02:15

let's go ahead and hit cancel.

02:17

This time,

02:17

let's show sketch 2.

02:19

Go to double click the mouse wheel to zoom out,

02:21

noting that we now have our profile and we have a path.

02:25

In this case,

02:26

let's take a look at suite.

02:28

When we're using the sweep for a surface tool,

02:30

once again,

02:31

we have very similar results that we do with our solid tools.

02:34

We can do a single path,

02:35

path and a guide rail,

02:37

or a path and a guide surface.

02:39

In this case,

02:39

let's just use the single path.

02:42

While this does look like a solid as we rotate it around,

02:45

we can see that it is just an open surface body.

02:48

We have options to determine the distance.

02:50

For example,

02:51

we can have this go a portion of the way on our path or even extend past the path.

02:55

In this case,

02:56

we're going to go completely to 1.0.

02:59

We can also use things like taper angles.

03:01

We have the option to twist along the path.

03:04

For example,

03:04

we can have it twist a small amount as it's going.

03:08

Once we're done,

03:08

let's go ahead and say,

03:10

OK,

03:10

to accept the suit.

03:13

From here,

03:13

we're also going to expand our bodies folder and show body one.

03:17

When we're dealing with multiple surfaces,

03:20

to put them together as a single surface body,

03:22

we need to use the modified tool stitch.

03:25

When we take a look at our bodies's folder,

03:27

we can see here that each body has a number next to it.

03:30

This represents the number of bases that belong to that surface.

03:33

When we use the stitch tool,

03:34

we can select groups of surface bodies,

03:37

and we can stitch them together as one surface body.

03:41

However,

03:41

we should pay close attention to our stitch results.

03:44

We can see here that we've got 16 free edges.

03:47

This is 4 on the end of this object,

03:50

and then the same 8 open edges on the other surface body.

03:53

However,

03:54

it's telling us that there are zero edges to be stitched.

03:57

Oftentimes what happens is there's a tolerance issue.

04:00

This means that the two surfaces down here are likely not close enough together.

04:05

As we increase the tolerance,

04:06

we should see that edge turn green.

04:08

This tells us that we're now within the tolerance range,

04:11

and when we select OK,

04:13

fusion will make up the difference between the two

04:16

surfaces and stitch them together as one surface body.

04:19

We can now see that we've got a single body and this contains 16 individual faces.

04:25

We also have other ways that we can connect or complete surface bodies.

04:30

For example,

04:30

we've got a patch tool,

04:32

and the patch tool will allow us to select profiles

04:35

and fill in those profiles with a new surface.

04:38

We have the ability to control tangency,

04:40

and we can also group all of our edges together.

04:43

For example,

04:44

if we select group edges and use the tangent option,

04:47

we have a tangent cap that's created at the end of our surface.

04:51

Let's go ahead and set this back to connected and say,

04:54

OK.

04:56

Creating a patch doesn't instantly mean that

04:58

it's connected to the other surface body.

05:01

We have to use the stitch tool,

05:02

select both surface bodies,

05:04

and join them together.

05:06

On the other end,

05:07

also note that we've got other create tools such as Loft.

05:11

Loft will allow us to go from one profile to another profile.

05:15

Once again,

05:16

we can use tools like tangency

05:18

to drive the direction

05:19

and make sure that we have a smooth transition with the surrounding surface body.

05:24

In this case,

05:25

we're not going to keep this as an option,

05:27

but I do want to note that we have several different things that we can do,

05:30

such as aligning to the edges of the surface we're connecting

05:33

or aligning to the surface.

05:35

In most cases,

05:36

these will give you the exact same result,

05:38

but in cases where we have trimmed surfaces,

05:40

you'll notice a difference.

05:42

If we want to turn this into a solid body,

05:45

we either need to cap and stitch the end

05:48

or use the thickened tool.

05:50

And before we do that,

05:51

let's take a quick look at a modification tool,

05:53

fill it.

05:54

When we're using the Fit tool on a surface body,

05:57

you may find that you need to make multiple edge selections

06:00

based on the tangency across multiple areas of your surface.

06:04

So if you see a red edge,

06:06

make sure that you do select across those edges,

06:10

or use the tangent chain option and ensure that you

06:12

do have tangency going all the way through your model.

06:15

Once we have a rounded corner,

06:17

it's just going to create a new face on our surface.

06:20

Note that now under Bo 6,

06:21

we've got 23 faces.

06:23

Because adding a filet in this instance is gonna create a new phase,

06:27

removing the edge that was originally there.

06:30

To turn this into a solid body,

06:31

we can use Create and we can use the thicken tool,

06:35

allowing us to select the surface and either thicken it inward or outward.

06:39

Keep in mind that this can be based on faces or an entire surface body.

06:44

When we're thickening an entire surface body,

06:46

we do want to pay close attention to the thickened values.

06:50

We have an option to thicken it inward,

06:53

or in some cases,

06:55

we can go in both directions.

06:57

If we use the symmetric option.

06:59

You can see that we're now thickening 0.5 inch inward

07:02

and 0.5 inch outward based on the original surface location.

07:06

When we say OK,

07:08

inside of our browser,

07:09

we're now going to have a new solid body,

07:11

as well as the original surface body that was used for that thicken.

07:15

This is a great benefit,

07:16

allowing us to create the original geometry and keep it inside of our browser,

07:21

and if we decide we don't need it,

07:22

we can always right click and select remove.

07:27

As you prepare for your certification,

07:29

make sure that you do explore surfacing tools,

07:31

but keep in mind that we won't be diving very deep into the surfacing tool set.

07:36

Make sure that you do understand some of the basics and play around with these with

07:39

your own models to make sure that you have a little bit of experience with them.

07:43

Understand the modification tools like the ability to add filets and champers,

07:47

and make sure that you are familiar with stitching,

07:50

unstitching,

07:51

extending and untrimming your surfaces.

07:53

Once you're done playing around with this,

07:55

go ahead and save the file and move on to the next step.
