Derived design

00:02

In this lesson, we'll learn how to create a Derived design.

00:07

After completing this lesson, you'll be able to: Use Derive and use Isolate.

00:13

In Fusion 360, we want to get started with the supplied data set, front suspension.

00:19

Oftentimes when we think about machining a part or setting it up for manufacture, we're thinking of a single part or a single component.

00:26

We don't have to deal with the big assembly of components because oftentimes it's just not required.

00:31

But there are times when the starting point is going to be an assembly.

00:35

In this case, we have a wheel and we have suspension for a Formula SAE car.

00:40

There are joint supply, things can move around inside of Fusion and we need to better understand how we can work with data sets like this.

00:47

So that way we can create all the geometry we need to hold the part,

00:51

but we don't have to worry about creating it inside of an assembly that could be used downstream for other work.

00:57

So we want to make sure we understand what options we have when we're doing this type of work.

01:03

The main option that we're going to be covering is something called Derive.

01:07

Derive is a way for us to drill down and identify a single component or multiple components that we want to isolate in their own design.

01:17

In this case, I'm going to be looking at the front rim.

01:20

And so that we better understand this, I can hide some of the other bodies.

01:24

And in this case, I might even want to right click and I might want to isolate so that way I'm focusing solely on the Rim Front.

01:32

From here, what I want to do is use my Create drop-down and select Derive.

01:38

We need to have a currently saved an up-to-date file so we'll save and continue.

01:43

And then the Derive dialog will open allowing us to choose bodies and components that we want to bring in to an existing design or create new.

01:52

We're going to solely focus on the front rim.

01:54

We can expand the Bodies to make sure that everything is coming along with it.

01:58

And we can even say to place it at the origin and bring along any parameters that are associated with it.

02:05

We'll say OK and the new design is created.

02:09

You'll notice that this is untitled because we haven't saved it yet.

02:12

But let's go ahead and just to quick save to make sure that we have this Derived version.

02:18

So I'm going to call this one fsae rim front derive.

02:25

Well, it's not strictly required that we put Derive inside of the file name.

02:29

It is helpful for us while we're learning to remember that this was a Derived version.

02:35

When we have a Derive, you'll notice in the bottom there's no history associated with it.

02:40

The timeline just simply has this derived from front suspension.

02:45

You'll notice that it tells us which version it was derived from.

02:47

And we can even open up the source document, we can choose a version or we can even break the link.

02:54

From here, we need to understand why we would do a Derive.

02:58

A Derive maintains a link back to the original front suspension.

03:02

So if somebody comes in and makes a change to the design, such as changes the location of the lug pattern or changes the layout of the spokes,

03:10

maybe they want 10 spokes instead of 8.

03:13

All of that information will be captured and transferred to the Derived version.

03:19

This means that you can still do all the work to setup the manufacturing environment.

03:24

You can make your fixtures, you can have everything designed and there will be a link back to that original.

03:30

So this is a great way for us to isolate a single or multiple components out of a larger assembly.

03:36

But we do lose the fact that we don't have that original design intent captured in the timeline.

03:42

If we come in and we break the link, it still is not going to bring in that information for us, it's still going to be a copy.

03:51

Another way that we can look at this is to make a copy, a Saved As version of the entire design.

03:58

I'm going to unisolate this and note that if I use my File drop-down, I have an option to Save As.

04:05

When we do Save As, we’ll create a copy that doesn't maintain a link to this original.

04:10

Then we can come in and do things like remove components that we don't want to see in our manufacturing environment.

04:17

However, we lose the link that parametric link between the designs.

04:22

Another way that we could do this is to put this design into another design.

04:28

We can drag and drop it in and we can maintain that link.

04:31

But again, if we are going to be making fixtures, we're going to be making Workholding for the rim for the manufacturing environment,

04:40

deriving that component out of the assembly is going to be the best option because we don't have to worry about all the other components,

04:47

or creating any new designs directly inside of an assembly that could be used downstream.

04:53

The last thing that you would want is to have some vises and Work Holdings inside of the center of this wheel,

05:00

and have that be a part of the main assembly of an entire Formula SAE car.

05:06

So for the purposes of this course, this lesson and just in general,

05:10

we're going to be working on Derive as the ideal workflow when we're dealing with an assembly.

05:16

There are instances where that doesn't make sense of course because it's not a one-size-fits all solution.

05:21

If you have to make changes to the original design intent, if you want to make changes to any of the timeline history,

05:29

then you're going to want to capture that in some sort of assembly file.

05:34

So that means that you might want to keep the entire assembly and you might want to work directly in there.

05:40

For our purposes, let’s go ahead and make sure that we save the front suspension even though we haven't changed anything,

05:45

and that we have our FSAE rim front Derive saved and we still have the link.

05:51

Because we saved a new version of the design, you'll notice that it's telling us it's out of date even though we didn't change anything.

05:58

So I'm going to update the link to the most current version to make sure that it captures any of that design history if there was any,

06:05

and then make sure that we save this before we move on to the next step.
