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.
