In this lesson we'll edit a generative model.
00:06
After completing this lesson you'll be able to edit a form and update a distributed design.
00:13
In Fusion 360 we want to carry on with our assembly that contains our generative frame.
00:18
At this point we want to figure out ways in which we can modify the frame itself.
00:22
We have a few options a few different things that we can do in order to modify the frame.
00:27
If we right click on the frame we'll notice that there is a break link icon.
00:31
Breaking the link will allow us to bring all of the features directly into the design we're working on.
00:37
In some cases you also have an edit in place.
00:41
Using edit in place will allow us to edit the generative model.
00:44
By using those specific options and temporarily bringing those features inside of this design.
00:51
So you'll notice that we have this associative edit in place if this is the first time that you've used this.
00:58
This associative edit in place tells us that references to other components will be captured in the assembly context.
01:05
You can toggle off the associativity from the edit and place menu at the top of the canvas.
01:10
We can also change default settings inside of our user preferences.
01:15
So notice it looks a little bit different. We have this blue bar around the outside
01:20
and we're working directly on the generative frame inside of this.
01:24
And we can use the associative and non-associative options if we wish.
01:28
We're not going to focus our attention too much on that.
01:31
But the first thing that we really want to do is we want to get rid of the cuts that are made
01:36
by subtracting information from our obstacles.
01:40
We created the obstacles with enough tolerance that we don't need to worry so much about cutting out these little areas.
01:47
So if we roll back the combined feature
01:51
you'll notice that what we see on the screen are going to be those obstacle bodies.
01:55
I'm going to expand the bodies folder and I'm going to hide these obstacles.
01:60
Note that they're all renamed with obstacle 1, 2, 3, 4, 5, 6, 7 and 8.
02:06
And also notice that body 22 is going to be the solid body for our frame.
02:11
If we don't want to use any of the obstacles we can select them,
02:16
we can right click and we can remove them from our design.
02:20
It's important that we use remove and not delete. As remove will place a marker in the timeline.
02:25
But if we roll the timeline to the end you'll notice that this combined feature no longer works.
02:30
And that's because none of the bodies that were used are actually still in the design.
02:35
So we're going to delete that feature, but you could also suppress it as well.
02:40
Note that we do have some slight interference or some tight clearances with the shock that we might want to work on.
02:46
We have, of course, some interference with the motor that we need to work on as well.
02:51
In order to do this we're going to be working inside of the organic form feature.
02:56
By selecting it notice that we don't have the option to edit this feature here.
03:01
When we're using edit in place we have options that allow us to make adjustments,
03:06
but not all of the options will be available.
03:09
I'm going to end edit in place and I'm going to go back into my data panel
03:14
and I'm going to open up the motorcycle frame design.
03:21
When we open up the frame design, it's important to note that the extrude cuts are still there.
03:27
So we're going to get rid of that feature.
03:29
We're going to go into our bodies folder, inside of this design, and we're going to remove all the obstacles.
03:37
So this is one of the differences between associative and non-associative and when we're using edit in place.
03:44
We're going to make a save to the file before we do anything else
03:50
and then we're going to right click on the organic form feature and we'll edit.
03:55
From here we want to make sure that we note a few things.
03:58
Anywhere this form surface intersects with one of our preserved regions, it's going to be frozen.
04:05
We can see that by taking a look and seeing these lightly blue colored edges.
04:10
The important aspect here is that all of these form bodies overlap those preserved regions
04:15
in order for the boundary fill to work and create a solid body.
04:19
So when we're making adjustments we're going to try to leave those frozen edges as is as long as we can.
04:25
If we have to make adjustments we need to make sure there's still some overlap.
04:29
I'm going to take a look at some of my modification tools.
04:32
First, I want to take a look at one that's called smooth.
04:37
With smooth I'm going to select a few of these various faces
04:40
and I want to see if I can smooth out this region a little bit.
04:44
We have a slider that allows us to influence how much is getting smoothed.
04:49
And what it's essentially doing is it's looking for an average between the selected faces.
04:55
Depending on the number of faces that you selected in the surrounding geometry,
04:60
sliding the slider up or down may make more or less of a difference.
05:05
In our case you can see that it was able to smooth those out and it looks pretty good.
05:10
And I'm pretty happy with that result, so I'm going to say, "okay" and allow it to keep that.
05:14
If we need to make more drastic changes, for example, where it overlaps the motor.
05:19
Then we're going to need to go in and use some of our manual tools.
05:23
So, in this case I'm going to go into edit form and I want to select a region.
05:30
We can use our selection tools and right now we're on box select. We can use box select to select various areas
05:37
and then we can use tools such as soft modification to allow us to determine how far out that influence is going to go.
05:47
I'm going to view this from the top to make it a little bit easier to see.
05:52
Then I'm going to grab this edge and I'm going to pull it out making those gradual changes.
05:60
I'm going to click in the canvas and I'm going to make some adjustments to the back end where the shock is.
06:08
So I'm going to double click on this edge, notice that it coils itself around.
06:12
And we still have soft modification on. So I'm going to pull this up, noting that the frozen edges are staying in place.
06:20
With those adjustments made, I'm going to select "okay" and finish my form.
06:26
It's going to go through the process of reconverting that to a surface body.
06:31
And then it's going to use the boundary fill feature in the timeline to create a solid body between that closed region.
06:36
And all of the preserved regions selected.
06:40
When we're post-processing a generative design there are many more things that we can do.
06:45
Depending on the complexity of your design, for example the small hole that's located right here.
06:51
You might determine that you need to spend extra time smoothing out those areas manually
06:56
or with certain tools like erase and fill or to remove a hole.
07:01
Once the design is once again updated let's go ahead and make sure that we save it and then we go back to our assembly.
07:12
Once we're back in our assembly we are greeted with a few warnings telling us that one of the components is out of date.
07:19
In this case our generative motorcycle frame, I'm going to use this option to update it to the most current version.
07:29
Once it's been updated you'll notice that the warnings go away.
07:32
And now our generative assembly has automatically been updated with the changes that we've made.
07:38
For example, the small hoop that goes over the shock body as well as the slight changes we made to the frame.
07:44
Note that inside of the browser we have an assembly context folder that happens whenever we're using edit in place.
07:52
So if we're using these contexts,
07:55
you can see that we can activate those local contacts and any changes that were made locally will appear only here.
08:02
For this design however we're not going to go through the entire process of making modifications
08:07
and adjustments to suit this design.
08:10
It's just important that we understand some of the things that are needed after we export a design from generative.
08:16
The more attention and time we pay to creating our obstacles, making sure that they're all smooth in the transitions.
08:22
Where this generative geometry is going to have to go around things,
08:26
the less time that likely will have to spend post processing.
08:30
So in this case everything looks pretty good. Removing those obstacles as a combined feature.
08:36
In this case left some slight issues that we wanted to address, but the rest of the geometry looks fairly good.
08:43
We could of course spend a lot of time smoothing things out, but there are a few other topics that we want to address.
08:48
So from right now let's make sure that we do save the file before we move on to the next lesson.
00:02
In this lesson we'll edit a generative model.
00:06
After completing this lesson you'll be able to edit a form and update a distributed design.
