Create and modify 3D solid features.

00:05

After completing this video,

00:06

you'll be able to

00:08

create an extrude feature to and from an object,

00:10

create complex hole and thread features,

00:12

create ribs and webs on a model,

00:14

and apply draft to a model.

00:19

In fusion,

00:19

let's begin by opening the supplied data set,

00:22

solid Feature sample.F3D.

00:24

We're going to begin by showing the body's folder

00:26

and expand the sketches and show the extrude to sketch.

00:30

We're gonna first begin by taking a look at the Extrude tool.

00:33

The extrude tool allows us to select two different types.

00:36

The standard extrude requires us to have a closed profile

00:39

sketch when we're trying to create a solid body.

00:41

There is also a thin extrude that allows us to use a

00:44

closed profile or open profile to create a thin walled part.

00:48

All the standard options such as draft or taper,

00:52

will work in both the thin extrude and the standard extrude.

00:55

However,

00:55

when you're using the thin option,

00:57

you do have a wall thickness value.

00:59

Let's reset the taper to zero and go back to our standard extrude tool.

01:04

With the standard extrude,

01:05

we have a couple of advanced options that we want to talk about.

01:08

First is our starting plane.

01:10

We can go from our sketch or profile plane,

01:12

we can use an offset value,

01:14

or we can select to go from an object.

01:16

When we're using an object as the starting,

01:19

we need to make sure that the starting face selection,

01:22

which can only be a single selection,

01:24

is able to completely encompass our sketch.

01:27

And what I mean by that is if we take a look at this top section of our object.

01:31

The top section is smaller than the profile of our sketch.

01:35

This means that we cannot use it for the selection in this case.

01:39

Instead,

01:39

we would have to use something like the bottom of our part,

01:42

in this case the entire flat face,

01:45

being large enough to completely encompass our sketch.

01:48

When we go to the extent type,

01:50

we also have a distance option,

01:52

a two object and through all.

01:54

When we use the two object in the extent type,

01:57

we have the option to do something a little bit different than our starting plane.

02:02

Let's go ahead and look at this from a front view.

02:04

If we zoom in,

02:05

we can see that we're extending based on the

02:08

curvature of our selected face into the part.

02:11

We also have the extent option to adjacent faces.

02:14

The adjacent faces will need to belong to the same body,

02:18

whether it's a solid or a surface.

02:20

But in this case,

02:21

note that there is a difference because it's using the adjacent faces.

02:24

To stop the new extrude.

02:27

Now we can use the same standard operations such as join.

02:30

We can use the cut option or intersect if the bodies are overlapping,

02:35

and once we actually select an object,

02:37

we can use values like offset

02:39

to offset away from that object or to put this

02:43

value as a negative and offset into that object.

02:46

This will give us a lot of flexibility when

02:48

creating things like inlays or insets into solid objects.

02:52

Keep in mind that when we use these options such as offset,

02:55

that we're taking the selected object or face and we're simply pushing it inward,

03:01

which is different than using something like a surface offset,

03:04

which takes into account the radius of curvature.

03:07

So as we offset inward or outward,

03:09

the object is going to get larger or smaller.

03:12

So keep all these things in mind.

03:14

We're going to select cancel as we don't need to save this feature.

03:17

We're going to hide extrude 2 and hide our bodies folder.

03:20

And next,

03:21

we're going to take a look at threads.

03:23

Let's go back to a home view and talk about creating threads.

03:27

For this example,

03:27

we're going to talk about a couple of options.

03:30

Under the Create menu,

03:31

we've got our whole tool and we've also got our thread tool.

03:35

The whole tool is a great way to create holes in objects that will contain metadata

03:40

that will be transferred later on or downstream inside of our designs.

03:44

For this example,

03:45

we're not going to be taking a look at drawings,

03:47

but the holes and thread tools can carry

03:49

that data into our detailed drawings downstream.

03:53

Let's select the whole tool.

03:54

The first thing that we want to identify is our placement options.

03:58

We've got a single placement and then we've got from sketch.

04:01

Using the from sketch option is great if you have a pre-defined

04:05

sketch that has multiple sketch points at all of your whole locations.

04:09

Let's first take a look at the single point.

04:12

We need to first select a plain or planer face,

04:15

and then we can slide or we can snap to a specific point.

04:20

We can use on-screen manipulators to change the overall size of our hole,

04:24

but we'll need to go into our dialogue to begin using some of the advanced settings.

04:29

For example,

04:30

instead of a simple hole,

04:31

we could use a counter borehole or a counter sinkhole.

04:34

Once again,

04:35

we can use the on-screen manipulators to change these values,

04:38

but we can also do this directly in the dialogue.

04:41

We can change the hole from a simple hole to be a clearance hole.

04:45

This is going to use data based on whatever standard you select for in this case,

04:49

the NC metric M profile will allow us to

04:52

create a clearance hole for a specific fastener.

04:55

We can also create tapped holes.

04:57

In this case,

04:58

let's go ahead and make this hole a bit bigger.

04:60

I'm going to drag this out,

05:01

make it a bit larger,

05:03

and

05:03

we want to select a larger screw.

05:05

In this case,

05:06

let's go ahead and select a 0.25 hole.

05:09

Here,

05:10

what we're allowed to do is create a tapped hole.

05:13

We can determine whether or not the end of the hole is angled,

05:15

such as a drill point,

05:17

or if it goes all the way through our object.

05:19

We can also determine whether or not the threads go all the way down.

05:22

We can see an on-screen manipulator here,

05:24

allowing us to drag how deep the threads go,

05:26

or once again,

05:27

we can do this in our dialogue.

05:29

We also have an option to select model.

05:31

When we select the modeled option,

05:33

this will create thread geometry inside of our part.

05:37

In most cases,

05:38

that thread geometry isn't needed,

05:39

but if your downstream workflow includes something like

05:45

you may want to include physical threads.

05:48

Let's go ahead and take a look at the whole tool once more.

05:50

In this case,

05:51

let's use the from sketch multiple holes.

05:54

In this case,

05:55

we don't need to select a plane because the sketch

05:57

plane will be the normal direction for our hole.

06:00

We simply need to select all the points where we want our holes to be located.

06:04

Let's go ahead and select these 3 points.

06:06

In this case,

06:07

I'm going to create this as a counter borehole.

06:10

I'm going to make the counter bore a bit larger and deeper,

06:13

and we're going to make sure that we've got a drill point on the end,

06:16

and we're going to turn off the modeled thread option.

06:19

Once again,

06:19

creating a quarter 20 hole will say OK.

06:23

Now we've created 3 quarter 20 holes with a cosmetic thread appearance,

06:27

and the metadata will still be the same as we

06:29

transfer this downstream to something like a detailed drawing.

06:33

One of the great benefits of using the whole tool is the fact

06:36

that the whole sizes are going to be sized appropriately for manufacturing data.

06:41

For example,

06:42

our quarter 20 hole needs to be drilled at about 0.202 inches.

06:47

This means that the whole size is gonna be correct for manufacture,

06:50

knowing that we need to tap it to a quarter 20 hole.

06:54

Let's go ahead and close that out,

06:56

and let's talk about the thread tool.

06:58

The thread tool is another way that we can add threads to our design.

07:01

This can be used for holes.

07:03

In this case,

07:04

we could select a hole in the model,

07:06

or it can also be used for bosses.

07:08

If we select a boss,

07:09

it will automatically determine the size based on the

07:12

default settings and the size of the geometry.

07:15

In this case,

07:16

we can see that it's automatically picking a

07:17

quarter 20 based on the standard settings.

07:21

In some cases,

07:21

we may want to decide to change the class of the thread,

07:24

which will affect the overall size or diameter of that boss,

07:28

and we can select OK.

07:30

Once again,

07:31

a cosmetic appearance is applied.

07:33

Let's right click and repeat that thread tool.

07:36

On the second one here,

07:37

you can see that it's a 3/8 by 16.

07:40

If we select the modeled option,

07:42

this is once again going to create physical threads on our part.

07:46

Go right click and do this one more time.

07:48

And notice that we can't select multiple geometries that are different sizes.

07:53

So if we hold down the control key and select multiple bosses,

07:56

you can see that it's going to keep them as the same size.

07:60

But remember that whether or not it's a hole or a boss,

08:03

fusion is going to resize the geometry

08:06

based on our settings.

08:07

This means that it will be the correct size for manufacture.

08:11

Next,

08:11

let's go ahead and hide the threads component and show ribs and webs.

08:16

Let's zoom into this component and let's go to the Create

08:18

menu and take a look at the rib and web tools.

08:21

First,

08:21

let's take a look at rib.

08:23

The rib tool is a great way to add a structural rib to a design by selecting a sketch

08:28

and increasing or decreasing the size of that whether

08:32

it's on screen or using some of the dialogue.

08:35

We can flip the direction and note in some cases the direction may

08:38

be incorrect and may require you to flip it to the correct orientation.

08:43

By default,

08:43

it's not going to have any draft angle or radius at the root of this rip.

08:48

If you do have the design extension,

08:50

you will have access to these tools.

08:52

Let's go ahead and select OK,

08:54

and then go to our create menu,

08:56

and let's take a look at the web tool.

08:58

The web tool is very similar in the fact that it lets us select geometry

09:02

and extend it out to the rest of the solid model.

09:06

We can hold down the control key and add additional selections,

09:09

noting that these are extending beyond the endpoint of those lines,

09:13

creating a complete web

09:15

inside of the interior space of our model.

09:18

These lines can automatically be extended based

09:21

on your geometry settings in the dialogue.

09:24

Note that we've got the extent type 2 next by default,

09:27

but there's also a specific distance.

09:29

Once again,

09:30

if you have the design extension,

09:31

you will have access to draft angle and fill it

09:33

radius that can be added at the current time.

09:36

We can also turn off the extend curves option

09:39

to create our webs exactly where our sketches are,

09:41

and in most cases,

09:42

you want to use extend curves.

09:45

Note that there is currently a warning in the bottom corner,

09:47

this simply tells us that the object that we

09:49

added our threads to is not currently visible,

09:52

not a big deal in this instance.

09:54

Let's go ahead and hide ribs and webs and let's show draft.

09:58

Oftentimes when creating a design,

09:59

you'll add draft or taper at the time of creation of those features.

10:04

For example,

10:05

creating an extrude,

10:06

it's very easy to add taper or draft during its creation.

10:10

However,

10:10

in some cases,

10:11

your designs may require you to add draft after the fact.

10:14

In this case,

10:15

we have a tool called draft from our modify menu.

10:18

The draft tool allows us to create a fixed plane draft or use a parting line.

10:23

In many cases,

10:24

the parting line option is going to give you more

10:26

advanced settings that may be required for complex shapes.

10:30

In this case,

10:31

we want to pick a pull direction,

10:33

a parting tool,

10:33

and the faces to draft.

10:35

The pull direction is going to be our top plane.

10:38

The parting tool is going to be this 2D sketch,

10:41

and the faces to draft will be the ones around the outside.

10:44

We're going to set the draft to two sides,

10:47

and we're going to add 2 degrees in both directions.

10:51

Once we say OK,

10:53

note that the draft has been added and there's now a taper

10:56

or a draft angle that's been applied from our parting line.

10:60

This automatically adjusts the tangent faces,

11:03

in this case the filets on the upper and lower corners,

11:06

and everything now has the appropriate amount of draft based on our settings.

11:10

Note that this will not work in all cases.

11:13

There may be instances where the complex shape just is not able to have this draft,

11:17

and in those cases you may need to do some manual

11:20

adjustments of your shape in order to get the appropriate draft.

11:24

But the draft tool on its own does have the ability to do a fixed plane parting

11:29

or using a specific 2D sketch or an edge on your model as the parting line.

11:34

It's important as we're preparing for our certification,

11:37

that we play around with these tools on several different models to make sure

11:40

that we understand how they work and where some potential limitations may lie.

11:45

Once we're done with this,

11:46

go ahead and move on to the next step.
