Stock creation

00:02

In this lesson, we're going to discuss stock creation.

00:06

After completing this lesson, you'll be able to: Use direct modeling tools, create a stock body and use Copy Paste New.

00:15

In Fusion 360, we're going to carry on working with our fsae rim front derive.

00:21

We're gonna be working with this part as a unique component.

00:24

So whether or not it's still linked back to the original design,

00:27

we're going to assume that this is our starting point and we need to prepare it for manufacture.

00:33

So the first thing that we're going to talk about is making a copy of this body and then simplifying it for our stock starting point.

00:39

So in order to do this, the first thing that I want to do is select it in the browser.

00:44

I'm going to right click and I want to create a copy.

00:47

Notice that we can also use Control and C or Command and C depending on the operating system you're working with.

00:53

From here, we're going to create a paste new and we'll do that by making sure that we select Paste New.

01:00

It's important to understand that when we create a new version of this, what we're actually doing is,

01:05

we're taking the existing point where the model currently stands and we're creating a duplicate of it that has no link back to the original.

01:13

If we were to simply copy it, then what we would be doing is making an exact copy that still linked back to the original.

01:20

So in this case, we have a new version.

01:22

So we're going to rename this new version and we're going to call this Rim Blank.

01:28

We want to work on the Rim Blank and prepare it for manufacture.

01:32

Currently, it's still not sitting at the origin.

01:35

There are some problems because we brought it in coming directly from our assembly,

01:39

and it was just at a position inside of the assembly where the wheel was turned and maybe tilted a little bit.

01:45

So in order to prepare it, we're going to start by first hiding the front rim and we're going to work directly on the Blank by activating it.

01:53

We're going to start to explore some of our direct modeling tools.

01:57

When we take a look at our direct modeling tools, what I mean is we have tools like Press Pull,

02:02

we have the option to delete or remove faces and patch the design, and there's some other ones that we can use like Move/Copy on specific features.

02:10

What we want to focus on to start with is going to be the inside of one of these spokes.

02:16

I'm going to begin selecting all of the fillets inside of here by holding my Control or Command key down.

02:22

And once I have all of these fillets selected, we’ll be able to delete them and allow Fusion to patch that geometry.

02:29

You want to make sure that you select all of them and that we don't leave any small slivers behind because that will affect the results.

02:36

For example, here you can see there's a small fillet and we want to make sure that we grab it on the other side as well.

02:43

If we forget these, then the patch will not work and we'll be starting from scratch with our selection again.

02:49

So moving around once again, you'll notice that there is a small section in between here and we'll need to zoom in to make sure that we select that.

02:57

You can also use other commands, such as Zoom to Fit and Zoom to Window.

03:01

Or if you're using a 3D mouse, you can rotate around.

03:05

But once we have all of these selected, let's zoom out so we can see the entire area and I'm going to go to Modify and Delete.

03:11

But again, note that Delete on the keyboard will produce the same result.

03:15

So it removed all of those rounded corners.

03:18

We can do the same thing by selecting this fillet and hitting Delete.

03:21

We can even select this inside pocket and hitting Delete as well.

03:26

And if we want to completely get rid of this opening, we can select all these internal faces and once again, once we have them selected,

03:34

making sure again we grab any small ones in the middle, we'll go back and hit Delete on the keyboard.

03:42

Now you can see we've completely removed that from the inside.

03:45

This is a great way to modify the design if we need to do something like create a Revolve.

03:50

If we're creating a Revolve, we want to have a center section or we want to have a line that sections through the model,

03:57

so we can use it to revolve a solid body.

03:60

There might be a bit more work that we need to do here.

04:02

But let's go ahead and start a new sketch on the top face.

04:08

And then we want to use this to create a new sketch that we can use for Revolve.

04:14

I'm going to draw a line from the origin and I'm going to come through this geometry.

04:19

It doesn't really matter exactly where it is.

04:21

But if you want to snap to some geometry, we can always use P on the keyboard to project,

04:27

and then we can snap the endpoint of our line to the midpoint of that section,

04:31

making sure that we are getting at the exact right midpoint so our projection in our intersection curves will be just fine.

04:39

From here, I'm going to create a new plane at an angle.

04:43

So I'm gonna select this and create a plane at 90 degrees.

04:46

This will completely go through the center of that spoke where we just removed all that geometry.

04:52

And now I can start a new sketch on that face or on that plane.

04:56

And then we can use that to create our section view.

05:01

Once we have it selected, let's go ahead and use Slice.

05:04

And you can see on the left hand side we have that open spoke and on the right hand side we have that solid section.

05:10

Now we can't use this as is, we'll have to go in to Create, Project/Include.

05:15

And in this case, we're going to use Intersect.

05:18

We can select the entire body and then we can say OK.

05:23

I don't need any of the curves on the left hand side.

05:25

So I'm going to select and delete them.

05:28

And then I do want to create a center line that I can use for the Revolve.

05:32

Now this can be a cylindrical edge or face or we can create an access if we want.

05:37

For our purposes, we can simply use that cylindrical edge.

05:41

I'm going to go to Revolve, our profile is already selected and for our axis, I'm going to go ahead and just grab that cylindrical face.

05:49

And what we want to do is we want to create a new body or we can join this with another solid body.

05:55

I'm going to select the New Body option and I'll say OK.

05:59

Then from inside the Bodies folder for our Rim Blank, we have Body2 which is our new Revolve and Body16, which is the original.

06:08

With Body16, I'll right click and select Remove and I'll show Body2.

06:14

So now we've created the version of this that is the starting point.

06:18

This is going to be our Rim Blank that we can use for our stock.

06:23

We also still have our Rim Front, so we can hide our Rim Blank and we can show our Rim Front.

06:28

We’ll activate the top level.

06:30

And now you can see here we have the original.

06:32

Original is just fine and the Rim Blank is just fine.

06:36

So now we have both of these bodies inside of this design that we can use for our starting point for our stock,

06:42

and for selection for all the geometry that we need to cut.

06:46

There's plenty more that we need to do in order to prepare this for manufacture such as import fixtures or create them.

06:54

But for right now, let's make sure that we do save this design before we move on.
