Solve a generative study

Solve a generative study.

00:05

In this video, we'll use a previewer, and we will solve a Generative Design study.

00:10

In Fusion 360, we want to get started with the supply dataset Generative Design geometry setup. Version 11.

00:17

This version is very similar to the one that we've been working on. However, there are some changes.

00:22

If we take a look at the front of the steering stem, we now have some additional obstacles,

00:27

as well as a tube that runs through the center of it to make sure that we don't have any build in that area.

00:32

We also have a slight change to the front of the Engine Geometry.

00:36

What we see here instead of a large fillet is we have more of a chamfer with filleted front and side edges.

00:43

The reason for this is because we really need to have a line of sight between our Preserve geometries.

00:49

This means that in order to get a build region or to get started on a generative solve,

00:54

we want to make sure that the Preserve at the front of the bike can see the engine mounts here,

00:59

and that the engine mounts can see the next one and so on.

01:02

There is still a problem in this area with the shock because we do have such a large region that is obscuring the line of sight here.

01:09

So this area is likely going to be problematic but a good way for us to check and tell is to use what's called the previewer.

01:16

Once you launch the previewer, there's a small gear icon for settings and generally I like to go to the high level of detail.

01:23

This will increase the mesh resolution and give us a better chance of seeing whether or not we're getting in a region that's being built.

01:31

Now oftentimes what will happen if we don't have line of sight or if we just barely are outside of that line of sight,

01:38

then it'll take a lot longer to get the first iterations of the solve going,

01:42

and then we'll have problems downstream just simply not getting enough iterations to get an adequate result.

01:49

What we can see here is that the build region is starting but it is going through some of our obstacles,

01:54

and likely over time, we would get a better result but it's going to cause a lot of computation to happen,

02:01

and ultimately it's going to affect the downstream results.

02:04

Because of this, I'm going to go to my unassigned geometry and show it, and there is also a piece of geometry in here that is a starting shape for us.

02:15

So inside of here, we're going to go to our Design Space dropdown and select Starting Shape,

02:20

and we want to select this Rough Frame Outline, and we'll select Okay.

02:24

This is going to give this Generative Solve a little bit better idea of where we want it to build.

02:30

If we hide the Obstacle Geometry, and we just take a look at this.

02:33

It now knows exactly where it needs to start and where it needs to build to,

02:38

and this will give it a better starting point and ultimately give us a better result.

02:43

While the Starting Shape is not required for all generative solves if you have complex geometry like this,

02:50

and we have a lot of obstacles that we need to make sure that we avoid.

02:53

It's a good idea for us to use that Starting Shape to better drive the starting point of our design.

02:59

Even though we're letting the computer decide, oftentimes we know about what we want it to look like just simply based on our own experience.

03:07

So from here we can select Generate.

03:09

It's important to note that we still do have a warning,

03:12

and the warning is telling us that we have an issue with the size of our part,

03:16

and that costing is going to be a problem.

03:18

And that the Additive Manufacturing or 3D printing is going to be a problem, because the part is just too large.

03:24

Since we're not using that manufacturing method, that's okay. But it's always a good idea to double check.

03:30

You can select Repair from here or you can go back to the precheck and take a look at what it's telling us.

03:36

So the study geometry is too large for 3D Print that's perfectly fine again because we're not using that manufacturing method.

03:43

The last step in the process before I go ahead and generate this is I want to go back to my Study settings,

03:49

make sure that my mesh resolution is okay.

03:51

And in this case, I'm actually going to use the alternative outcomes.

03:55

Because we want to explore as many possibilities, we want to use that alternative outcomes which again is a preview functionality.

04:02

So you will need to go into your user preferences, make sure that you do go to preview features,

04:08

select Generative Design and make sure that you turn on the experimental generative solvers and features.

04:15

Once that's turned on, I'll go back to Generate.

04:17

Now that I'm happy with all the settings and note that I am going to have to use 33 cloud credits.

04:23

In order for you to follow along with the course, you will need to solve the generative study which will be that 33 cloud credits.

04:30

If you don't solve the generative study, we will still provide the results.

04:34

So you can follow along with the rest of the course, creating simulations and following along with the downstream manipulations.

04:40

But in order to go through the Explorer interface, you will need to solve your own study.

04:44

It's not an option to have a file that contains those generative solves because all that data is stored on the cloud,

04:51

and it is linked to the original design, a copy of the design or download link simply won't contain that data.

04:57

When solutions are being generated, Fusion 360 will automatically bring you into the Explorer interface.

05:04

You can see the iterations being created live, and this process tends to take a little bit of time.

05:10

Depending on the amount of materials and manufacturing methods, the study settings and your objectives,

05:17

Whether or not you're using these additional solves and features,

05:20

This process could take as little as under an hour or it could take several hours to start to see converged or completed results.

05:28

For this process, I fully expect this to take at least an hour to have converged results on at least a few of the iterations.

05:36

So you can feel free to watch and explore these as they're being generated.

05:42

But for the course, we're going to check back in once everything is converged and solved, and then we can explore the results together.
