Create obstacle geometry for the gas tank and motor.
00:06
In this video, we'll create a sketch. Use the Edit Model workspace. Use Extrude and Combined.
00:13
In Fusion 360, we want to make sure that we get started with Generative Design geometry setup V4
00:19
or if you decided to create your own obstacle for the front of the frame, then you can go ahead and carry on with your own design.
00:27
Now that we have some obstacles for the frame.
00:30
We want to make sure that we represent the gas tank and the motor to make sure that the frame doesn't get built into those areas.
00:37
So let's navigate back to Edit Model, and let's begin creating the gas tank first.
00:42
To do this, There are a few things that we can keep in mind.
00:46
Right now, everything that we've created are inside of the Bodies folder.
00:49
We could rename these bodies as Preserves or Obstacles if we wanted to.
00:54
We can also create new components inside of here.
00:57
Keeping in mind that inside of Edit Model, there is no capture position and there are no joints.
01:04
So anytime we have a component, the components are free to move about in here.
01:08
You can see that pieces of the shock are easy to move, and there's no revert.
01:12
So we want to make sure that we use Undo to put those back in position,
01:16
and note that the creation of bodies is actually helpful in this case when working inside of Edit Model.
01:23
So the next thing that we want to do is we want to make sure that we have enough geometry to represent the gas tank.
01:29
So that way the frame gets built in a manner that makes sense for our design.
01:34
Keeping in mind that the frame does need to go to the upper shock mount and ultimately it needs to go to a few areas.
01:40
But we want to make sure that we are able to incorporate the frame that looks similar to the original design
01:46
that's just optimized using our Generative Design study.
01:49
So let's get started by creating a sketch, and in this case, I'm going to use once again the Y Z Plane.
01:55
Not really concerned with the location of the origin, I just want to start using my Sketch Line tool.
02:00
I'm going to begin sketching up here at the front of the frame.
02:04
I'm going to start a line that starts about where the steering stem is and if we want to actually snap to this geometry,
02:12
we can use escape, and then we can go down to Project Include and select Intersect or Project.
02:18
Intersect will create a slice through the center of this geometry, and project will allow us to just bring in one of the edges.
02:25
Either option will be fine but in this case, I chose to use Intersect.
02:30
So starting from that upper position, I’m going to zoom back out.
02:34
I'm going to simply begin drawing the upper portion of the frame or the lower portion of the gas tank.
02:41
I'm going to make sure that it comes all the way back and encompasses a little bit of the seat.
02:47
It doesn't need to match the shape of the gas tank. It just simply needs to encompass this area.
02:55
I am going to go back, and I'm going to add a constraint here to make sure that I do have a tangent constraint.
02:60
And again, it's really only for visual reference.
03:04
I'm not concerned with adding complete dimensions for this body but if you want to, you can select some of the sketch entities,
03:11
and you can lock them in place rather than adding full dimensions.
03:16
But just note if you want to make any changes, you will need to go back later on, and you'll need to unlock those.
03:22
By locking them, you can see that we fix them in place, and now we have a representation of the gas tank.
03:28
Let's finish the sketch and let's select Create and Extrude.
03:33
I’m going to begin pulling this out, and I simply need to make sure that it goes past where our frame is going to be generating.
03:39
You can see here that we've got some obstacles. So I'm going to come out a little bit farther which is about 250 millimeters.
03:46
It's going to be symmetric, and it's going to be a new body.
03:50
We'll say Okay, and now we have an area where Fusion 360 knows not to build our frame.
03:56
I am going to go to Modify, fillet and add a fillet on this bottom edge just to round it off with 100 millimeter fillet and say Okay.
04:05
If we view this from the right hand side, now you can see that we do have an area,
04:09
where the frame is not going to be built because this will be one of our obstacles.
04:13
But we do need to take care of the rest of the motor.
04:16
There are a lot of different parts and components for this motor, and it's just simply not feasible for us to select it as an obstacle.
04:24
There are also a few things that are missing. The throttle bodies for the fuel injection system, the intake or air box.
04:30
There are a lot of components that just simply aren't there.
04:33
So we need to pick and choose areas that we want to make a simplified version and some that we want to simply just select what's there.
04:42
For example, this cover, we could very easily select.
04:45
However, the clutch cover has a lot of openings and components inside and that will just complicate the calculations.
04:51
So looking at the bodies that we have if we expand the Bodies folder,
04:55
we have the upper mount for the shock, and then we have some hardware for the frame.
05:02
You can see that the hardware goes through our mounting boss and then on the backside of the boss, This portion here is the actual frame.
05:10
So we want to make sure that we represent exactly where these objects need to start,
05:15
and we make sure that we do have a little bit of space that we can deal with.
05:21
So it can be difficult for us to select some of this geometry at times.
05:26
So what I want to do is I'm going to hide some of the geometry, in this case Body 29,
05:33
and Body 30, I'm going to hide those, and I also want to find and hide these portions of the frame.
05:38
So we'll go into the bodies, so you can see right here that we have rear and front frame lugs on the right hand side.
05:46
Now that we have those, we can begin sketching.
05:49
I’m going to go ahead and select this face and create a sketch.
05:53
I'm going to use this as the basis for everything.
05:56
It's important to note that these will not necessarily be at the same position.
06:02
We want to encompass a lot of the other geometry of the engine to make sure that we are avoiding it.
06:07
So I'm going to start by using the Circle tool at that position and simply draw a large circle.
06:13
For this side, we'll need to use project which is P on the keyboard,
06:17
and then I'll use the Circle tool which is C. And once again I'll draw a large circle.
06:22
I'm going to select both of these, and I'm going to make them equal.
06:27
And then I'll give them a dimension by using D on the keyboard, and I'll simply make them 70 millimeters.
06:33
There's really no rhyme or reason to that value. I simply want to make it large enough that I can begin sketching an obstacle.
06:41
From here, I'm going to use my Line tool.
06:44
I know that I need to avoid the shock, but I really want to be careful with what I'm putting in here
06:51
because the shock is really more of a critical feature for designing the rear swing arm.
06:56
So the frame is going to be coming down and coming up to this lug here.
06:60
So I want to make sure that my obstacle comes back, up and allows us to sort of cap off that shock area,
07:11
and then I need to go up and into the gas tank.
07:15
Once again, I'm not going to be extremely concerned about dimension in these.
07:19
I simply want to have a placeholder to make sure that my frame is going to go around some of these components.
07:26
So I'm going to come down noting that I do have an oil cooler here and likely there's going to be other components inside of the frame.
07:33
We want to make sure that it builds around these, so I'm going to come down,
07:39
and underneath where the exhaust would come out, noting that the frame is likely not going to build that low,
07:44
but this does give me an opportunity to help represent these areas.
07:48
I'm going to come back up to that position and then say Okay.
07:52
I'm going to finish the sketch, and then I'm going to use Extrude,
07:57
and I simply want to select all of these different areas,
08:01
and even the center is going to be fine, We can select that, zoom out,
08:07
and then we need to decide how far we're going to take this.
08:11
So I'm going to bring this all the way in and rotate around to the other side,
08:18
And I want to be careful with how far I go because I don't want to simply cut away everything.
08:23
So I'm going to bring this back a little bit and note that I want to go to the back side of my mounting bosses.
08:29
So I'm going to bring this back, find where the engine starts to come back in and instead of cut,
08:35
this is going to be a new body and instead of distance, I'm going to say to Object.
08:40
I'm going to hold down the left mouse button in this area until I get a Face Selection option, and then I'm going to bring it up to that face.
08:49
We'll say okay, and now we've created a new body that is going to allow us to represent some things that we want to avoid.
08:56
We want the frame to begin coming around this front section.
08:60
So I'm going to use fillet, to add a filleted corner on the front. I’m going to begin dragging this back, make it about 250 millimeters.
09:09
Then we'll use the Plus icon to add a Selection set.
09:13
We're going to add these upper edges, and these lower edges here, and we'll add 100 millimeters to it.
09:19
Notice that this gives us a problem because of this horizontal edge.
09:23
So in some cases, you might need to do this in two steps.
09:27
For this example, we will need to do it in two steps. I'll simply come back, and I'll add that 100 millimeter fillet.
09:34
You can see now it gives me something nice and smooth for us to wrap the frame around.
09:40
We're going to say okay, and then we'll go to Modify Combine and simply add this in the gas tank together.
09:47
Why they don't strictly need to be added together? There's really no reason why we can't add them together.
09:53
It just simplifies the selection process.
09:56
There are some other things that we want to be concerned with and that's how the frame is going to get attached back here.
10:01
So once again I'm going to come in and select Fillet. I'm going to fillet these corners.
10:06
I might need to rotate this around to select them,
10:09
and I just want to make sure that this is nice and round giving us plenty of room to wrap the frame back into here, and then we'll say Okay.
10:18
We're not expecting the frame to go back but if we did carry it on and include the subframe in the generation,
10:24
then we want to make sure that we include some of these other areas.
10:27
But for our purposes, this gives us a nice stopping point for the frame to build up against,
10:33
and we've got the rounded front section, so it can come off of the steering stem, wrap around this and understand exactly where it needs to build.
10:40
In terms of other objects that we want to avoid, We are going to be using things like some of these engine covers.
10:46
So let's finish Edit Model and let's go back to our Obstacle Geometry, and we'll select the Gas Tank,
10:52
we'll select this Engine Cover as well, we'll say Okay and we'll see what's left behind.
10:58
You can see there's some hardware, there's a little bit of a gap or a spacer here for the oil pan.
11:03
So we can always go back and we can select that as well if it was something that we didn't include in our Obstacle Geometry.
11:09
And again, we also want to make sure that we don't build where the shock is.
11:13
So we want to make sure that we select that upper portion of the shock to make sure that we are avoiding that as well.
11:20
So now it looks like we've got a couple green spots.
11:23
We might need to bring them back into visibility by going into our frame,
11:27
and make sure that we bring in those frame lugs to make sure they are visible.
11:32
But now we've got the green mounting positions,
11:35
and we've got some obstacles that we could bring back as well going into bodies, make sure that we bring those back into visibility.
11:41
We can see exactly where the frame is going to begin to build.
11:45
If there are any other objects that we want to avoid, these are timing covers, we can select those to make sure that they are included,
11:52
and this housing here which is going to be our clutch housing.
11:55
We can include that as well but we do want to be careful that we don't select bodies that are too complicated.
12:03
So again, I'm not going to select the clutch cover housing. I'm not expecting the frame to even try to build out here.
12:08
So it's not worth including it in the calculations.
12:11
But at this point, we have quite a good starting point. We have a lot of geometry defined as obstacles, which is exactly what we need to do.
12:19
We're not considering the design of the frame.
12:22
We're just simply telling fusion exactly where the frame needs to be and exactly where it has to avoid.
12:28
So at this point, let's make sure that we do save this design before moving on.
00:02
Create obstacle geometry for the gas tank and motor.
00:06
In this video, we'll create a sketch. Use the Edit Model workspace. Use Extrude and Combined.
00:13
In Fusion 360, we want to make sure that we get started with Generative Design geometry setup V4
00:19
or if you decided to create your own obstacle for the front of the frame, then you can go ahead and carry on with your own design.
00:27
Now that we have some obstacles for the frame.
00:30
We want to make sure that we represent the gas tank and the motor to make sure that the frame doesn't get built into those areas.

01:04
So anytime we have a component, the components are free to move about in here.
01:08
You can see that pieces of the shock are easy to move, and there's no revert.
01:12
So we want to make sure that we use Undo to put those back in position,
01:16
and note that the creation of bodies is actually helpful in this case when working inside of Edit Model.
01:23
So the next thing that we want to do is we want to make sure that we have enough geometry to represent the gas tank.

11:13
So we want to make sure that we select that upper portion of the shock to make sure that we are avoiding that as well.
11:20
So now it looks like we've got a couple green spots.
11:23
We might need to bring them back into visibility by going into our frame,
11:27
and make sure that we bring in those frame lugs to make sure they are visible.
11:32
But now we've got the green mounting positions,
11:35
and we've got some obstacles that we could bring back as well going into bodies, make sure that we bring those back into visibility.
11:41
We can see exactly where the frame is going to begin to build.
11:45
If there are any other objects that we want to avoid, these are timing covers, we can select those to make sure that they are included,
11:52
and this housing here which is going to be our clutch housing.
11:55
We can include that as well but we do want to be careful that we don't select bodies that are too complicated.
12:03
So again, I'm not going to select the clutch cover housing. I'm not expecting the frame to even try to build out here.
12:08
So it's not worth including it in the calculations.
12:11
But at this point, we have quite a good starting point. We have a lot of geometry defined as obstacles, which is exactly what we need to do.
12:19
We're not considering the design of the frame.
12:22
We're just simply telling fusion exactly where the frame needs to be and exactly where it has to avoid.
12:28
So at this point, let's make sure that we do save this design before moving on.
