Simplify workspace

00:02

Simplify Workspace.

00:05

In this video, we'll create a new simulation study, we will enter the simplify workspace and we’ll use model preparation tools.

00:14

In Fusion 360, we want to carry on with our motorcycle rear set model prep.

00:19

We're going to move from the design workspace and navigate to simulation.

00:24

The first time you enter the simulation workspace, you're prompted to select a new study.

00:29

By default, Static Stress will be selected,

00:31

and there's information about what a static stress study means and what the results can help you investigate.

00:37

If you want more information on any of the specific studies, you can always view the Fusion 360 help file or you can use help me choose a study type,

00:45

which will walk you through some of the various parameters that are calculated for each of the studies,

00:50

and help you choose which study best fits your needs.

00:54

For our purposes, static stress is the right choice so we'll create a study.

00:59

Once we do this, we're now inside of the simulation workspace which gives us access to simulation tools.

01:05

The first thing you'll notice is that our toolsets are different.

01:08

The browser looks different and we no longer have a timeline at the bottom,

01:12

and that's because in general simulation workspaces, not for creating or modifications of any designs,

01:18

but we do have a tool called Simplify that allows us to make modifications inside of the simulation workspace without affecting the original design.

01:27

So to get started, let's select Simplify and take a look at the tools we have available.

01:32

The first thing you'll notice is that it's a much different toolset at least on the surface from in the design area.

01:39

What we do have is some solid and some service tools and they will exactly mimic what we have in design with a few additions.

01:47

When we look at Create, we can create what's called a new simulation model.

01:51

A simulation model will be able to have data that's associated with it such as different studies and load conditions.

01:58

This will allow us to make design changes.

02:01

Design changes are important because they don't affect the original design,

02:04

and allow us to explore some things that can be either helpful to our simulation study or maybe remove features that are problematic.

02:12

There are also modification tools,

02:14

and you'll notice that most of the tools look the same with the exception of remove features, remove faces and replace of primitives.

02:22

You'll also notice that some of the tools are not here.

02:25

Things like delete are not on this list because they are encompassed inside of remove faces and remove features.

02:31

It is important to note that if you go to your user preferences,

02:34

there's an option to turn on some of these simplify tools inside of the design workspace.

02:39

If we navigate to design and take a look at, enable, arrange and simplify tools.

02:45

We're going to focus on making modifications only and simplify because we don't want to modify the original design.

02:51

So let's focus on what we can do inside of here and what that means to our design and our simulation setup.

02:58

First we want to expand our model components.

03:01

In this case, we're only interested in the frame mount and the peg pivot.

03:05

We want to remove all the other components in this design because they're just not needed for our simulation.

03:11

What we're going to do is first right click on foot peg and we want to select Remove.

03:17

You'll note that this leaves behind all the other components.

03:21

Another option we have is to select the components that we want, in this case our frame mount and our peg pivot,

03:27

and then we can remove all other components.

03:30

You'll note that by doing this, it makes the process much quicker and easier if you have a large assembly.

03:37

Now we're left with just the peg pivot and the frame mount.

03:42

But there are some additional things that we need to do in order to prepare this for simulation.

03:47

First, I want to hide the peg pivot and I want to focus my attention solely on the frame mount.

03:53

Another important note is that while we do have components inside of simplify, we are not capturing the position of those components.

04:02

No joints can be used inside of simplify.

04:05

What that means is you can accidentally move components but you're not prompted to capture their position.

04:11

So it's extremely important that you make note of where the components are,

04:15

and if you need to you can ground them in place to make sure that they don't accidentally move.

04:21

We're going go ahead and hide the peg pivot and focus our attention solely on the frame mount.

04:26

We want to remove the physical threads that are inside of this design and the small chamfers on the outside of the bracket,

04:32

as they're not going to be helpful for our simulation set up.

04:35

In order to do this, we're going to go to Modify and select remove features.

04:39

First we'll select the body of interest.

04:42

You'll note that instantly it brings up a list of features that it's looking for.

04:46

Things like fillets, holes, chamfers, extrudes and revolves.

04:50

There's also other section and select all.

04:54

If I de select Select All, you'll notice that these holes are still highlighted.

04:59

We do have a manual feature selection which will allow us to add or remove specific selections.

05:05

And once we're happy with those selections, we hit delete and it allow it to remove those.

05:11

If we deselect the body, you'll notice that now the holes on the top and the bottom are still there with the threads.

05:17

But the one in the center has the threads removed.

05:20

Let's go ahead and re select it.

05:21

We'll do our manual selection one more time making sure that we do select these threads and we try the delete again.

05:30

You'll notice this time that it actually removed the entire hole and this is not what we want.

05:35

So let's use Undo.

05:37

Let's go back into remove features.

05:39

Select the body and this time we want to use Other.

05:42

There's a slider that allows us to grab larger and smaller features on the design.

05:47

Let's drag this until it grabs the threads.

05:50

Let's hit Delete and notice that it's only removing the center.

05:53

If we hit Delete again those holes are still there.

05:57

So when we're talking about removing physical threads, the physical threads are often problematic for this tool,

06:04

so you might have to go in and manually remove them by selecting faces if the tool does not give you the appropriate results.

06:12

Fortunately, this is easy to do in Fusion 360.

06:15

We simply zoom in.

06:16

We'll select the faces that we are interested in.

06:18

In this case, I'm going to use control.

06:20

If you're on a Mac you can use command to select both sides of the threat in the inside and then hit Delete on the keyboard.

06:27

Then let's go ahead and pan down to the other threads.

06:31

Once again selecting the inside and outside faces of the threads as well as the upper portion holding down control or command,

06:38

to make sure that we do get all of those faces.

06:41

And then hit Delete on the keyboard.

06:44

We go back to our Home view.

06:45

We can now see that we've removed those but the hole size might not be correct.

06:50

Let's use Inspect and measure the hole size.

06:53

In this case, the diameter of the smaller hole is 8.526.

06:58

If we select the larger ones, you can see that the diameter is 10.198.

07:03

So it's not the correct size, they're too large and they need to be reduced.

07:08

We can do that with other tools such as Press Pull.

07:11

By selecting these faces. We can reduce their size down to the correct amount.

07:15

If you need to, you can manually zoom in or we can manually enter a value inside of the dialogue to get them to the right size.

07:22

For this example, we're going to reduce them down 1 millimeter which makes them 8.198 millimeters,

07:28

which is close enough for our example as it's not going to have an overall effect.

07:33

But note that there is a difference when we're talking about using the manual deletion as opposed to using the tool.

07:39

And it's important that you verify the minor diameter or major diameter of the hole that you're removing threads from.

07:46

Let's take one more look at remove features but this time we're going to select the body and we're going to focus solely on chamfers.

07:52

When we use the chamfers, notice that it's selecting the chamfers on the bosses as well as the front and back edge of the device.

07:60

In this case, I'm going to select delete to remove those chamfers and then I can bring my peg pivot back.

08:06

Now we have a simplified version of our bracket and we have a simulation model for this bracket where we can begin to set up our simulation study.

08:15

Before we get to that point, I am going to rename simulation model one.

08:19

This is going to be bracket and frame mount.

08:26

This is going to be important because we're going to explore several simulation studies,

08:30

and these will include the bracket and the frame mount and some of them will just have the frame mount by itself.

08:37

So let's select Finish Simplify.

08:38

And when we go back into our simulation study,

08:41

you'll note that the name of our simulation model is now bracket and frame mount and study 1 static stress still has its original study1 name.

08:50

From here, we can begin setting up our materials, our loads and our constraints that are defining what happens to this model,

08:57

and our context sets that determines how they are going to be connected.

09:00

But before we make any other changes, make sure that we do save this before moving on.
