Create and modify solid and surface features

create and modify solid and surface features.

00:06

After completing this video, you'll be able to create extrude features.

00:10

Using driven height options, create a patch surface,

00:13

apply filets and champers to a model.

00:15

Split bodies and faces

00:20

infusion 3 60.

00:21

Let's get started with the supply dataset locking fixture dot f three D.

00:25

We want to begin by exploring some of the more advanced extrude options that we have.

00:30

So to get started.

00:31

Make sure that in the sketches, folder the key feature sketches visible.

00:35

And then we want to select, create extrude.

00:38

The first thing that we want to do is we want

00:40

to note that we're going to be selecting closed profiles.

00:43

Extrude can also be used on open profiles using the thin extrude option

00:49

from here.

00:49

Once we have our profile selected as we begin to drag these down,

00:53

they'll create new solid bodies

00:55

until it begins to overlap or intersect with another body.

00:59

Note in the operation section we have new body until we get

01:02

down to an overlapping region and then it automatically defaults to join.

01:07

If we overlap more of the body, it will default to cutting

01:12

So we can see here how it changes. Just by using the onscreen manipulator

01:16

as the dimension dialog is active for the distance of our extrude.

01:21

If we were to select a face or vertex,

01:23

it's going to automatically measure that distance for

01:26

us and in put it in the distance.

01:28

Dialogue.

01:29

This however, is not a parametric relationship.

01:32

It's a one time measurement that happens when we make our selection.

01:36

We can change the extent type to be to object and we can select a face.

01:42

And in this case this will maintain a parametric relationship.

01:46

This means that if the model happens to change before this point in our timeline,

01:50

that key feature extrude would update based on our selection.

01:54

At this point. Let's go ahead and select joint.

01:58

Next we want to create a fill it by going to modify and selecting Philip.

02:03

We're going to grab a single edge and begin to drag this in 2.05.

02:07

After we make that selection note,

02:09

we're no longer able to select another edge unless we hold down the control key,

02:14

we can move around and even select through solid bodies,

02:17

making sure that we have all the additional edges.

02:19

We want to apply the fill it to.

02:21

Once we've applied those, we can select Okay

02:25

next we want to take a look at using split

02:27

body and split face and figure out how these differ.

02:30

When we select split body,

02:32

we're gonna be cutting a solid body with either a splitting tool that could be a

02:37

surface a face that belongs to that solid body or another solid body a plane.

02:43

Or in some instances we might be using a sketch as a split tool.

02:47

We're going to select the body. Then navigate to our splitting tools.

02:50

And let's select this face here.

02:52

Note that by default it's going to extend the

02:55

splitting tool which will cut through any solid geometry.

02:58

Once we say, okay, if we expand the bodies folder,

03:00

we have the original body and we have four additional pieces that have been removed

03:06

for right now,

03:06

I'm going to select and hit delete on the keyboard to undo that split feature

03:11

from the modified drop down. We also have split face and a silhouette. Split.

03:16

We're going to explore splitting face and in this case the faces

03:20

to split are going to be the inside faces of this part

03:24

and are splitting tool is going to be one of the default planes.

03:28

If you have any difficulty selecting this,

03:30

hold down the left mouse button and then you

03:32

can find Y Z plane directly through there.

03:36

We're going to select OK

03:38

and note now in the bodies folder we still have a single body.

03:41

However, these faces have been divided up

03:44

using split face is a great way to separate different faces

03:48

on a body that you may want to use for modification.

03:50

Later

03:52

let's go ahead and select the split feature and hit delete

03:56

next from modify.

03:57

We want to select champ for I'm going to select all the upper edges of the part.

04:01

I'm going to select these inside edges.

04:04

Once again, we can select through solid geometry

04:07

And this upper outside edge.

04:09

I'm gonna put a chance for of .02 and select OK.

04:15

With that chant for applied.

04:16

We can now see that all of those upper

04:18

edges have been smooth and added that pampered feature.

04:22

Next let's rotate around to the bottom of the part.

04:25

There are sometimes when you're preparing a model for

04:27

manufacturer that you might want to remove certain features.

04:31

Fusion 360 has direct editing tools which will allow us to

04:34

remove certain features like these tapped holes or these counter boards.

04:39

In this case we don't actually want to remove the feature.

04:41

But what we want to do is we want to create a patch that will cover them.

04:45

This can be helpful in cases of three D.

04:47

Manufacturing or creating a three D tool path to

04:50

prevent the tool from dropping into those holes.

04:53

To do that.

04:53

We want to navigate to our surface tools,

04:56

select patch and we can create a patch over that hole.

04:60

I'm going to select.

05:01

Okay, but note that we can also use the patch tool on the entire outside border.

05:06

This is going to create one large face that will

05:09

cover all the holes in times of programming tool paths,

05:13

it can often be easier to patch an entire face rather than each individual surface.

05:18

This is because it's much easier in the selection process in fusion 360

05:22

to use that as a constraint for preventing the tool from dropping in.

05:27

Either option will work just fine.

05:28

Just note that with the single hole option,

05:31

you will need to repeat it three more times in order to create all of those patches.

05:36

Another important note is that anytime we create a body a sketch or even a feature,

05:40

we can rename these.

05:42

So for example, Body seven,

05:44

we can call this our base patch and that base patch will be

05:48

more representative when we use it later on in a tool path.

05:51

There are other things that we can do and other

05:53

options in each of these features that we can explore.

05:56

If we double click on the patch,

05:58

note that each of these has a connected option next to it,

06:01

which can be tangent or curvature based.

06:03

We can also click an option to group all edges together and

06:07

add tangent C to all of them at the same time.

06:10

This can be problematic based on your selection.

06:13

For example,

06:13

this outside Edge here is not using the correct reference for a tangent C.

06:19

So in this case we would want to make sure that we flip the tangent C.

06:22

And we would have to do that individually for those edges.

06:25

We can see Edge seven here,

06:27

we would need to find edge seven inside of our dialogue

06:30

and once we find Edge seven we can change tangent C.

06:33

And flip the direction for that specific edge you can see here this makes a

06:37

much nicer patch but in the end this is not the result that we need

06:43

let's go ahead and navigate back to a home view and

06:45

make sure that we do save the design before moving on
