Create obstacle geometry for motor mounts.

00:06

In this video, we'll create a sketch. We’ll use the Edit Model workspace. We'll use Extrude, and we'll use Connector Obstacle.

00:15

In Fusion 360, we want to carry on with our Generative Design geometry setup.

00:20

We've already selected some preserve geometry that was contained inside of this design but now we want to create some of our own.

00:27

We're going to get started by taking a look at creating some obstacle geometry using Edit Model.

00:33

Edit Model allows us to create geometry that is only included in our Generative Design studies.

00:39

This means anything that we do in terms of modifying, editing, removing or even adding geometry to our design doesn't go back to the design workspace.

00:49

This can be extremely helpful because we can explore different design ideas without having to affect the original design.

00:57

What we're going to do is we're going to explore creating some obstacles for our motor mounts.

01:01

In order to do this, we want to explore a couple different ways that we can produce this geometry.

01:07

First from the Create menu, we can simply create a new sketch.

01:12

To do this, let's select Create Sketch and let's take a look at our shock.

01:18

We're going to select the outside face of the shock, and then we're going to use some of our standard tools such as Center Diameter Circle.

01:24

And in this case, I'm going to draw a 55 millimeter diameter.

01:28

Remember that when we start a new Sketch on a face,

01:31

it's going to automatically bring in that 50 millimeter outside diameter as well as the inside diameter.

01:36

So from here, I'm going to finish the sketch. I'm going to select Create Extrude.

01:41

And I'm going to begin by extruding the larger diameter as well as the center portion out and away.

01:48

I'm going to bring this out a distance of 35 mm, and I want to create a new body.

01:53

Then I need to go back into my model components into my sketches and the sketch I just created.

01:59

I want to extrude once more, and this time I'm going to grab the center, I'm going to bring this all the way into the middle.

02:05

You might need to go to a front view but note that at 50 millimeters, we’re right in the center.

02:11

From here, if we select Join, it's going to join it to all the solid bodies.

02:17

So we're going to select New Body, and we'll use Combine to join it together.

02:21

Let's rotate this slightly and hide our sketch.

02:25

Next, I'm going to use Create and Select Mirror.

02:28

I'm going to mirror specific bodies including this outside one that we just created,

02:33

and we'll need to expand our Bodies folder and select Body 27.

02:37

The mirror plane is going to be our standard plain, and it can be problematic to find this with all the other geometry.

02:44

It's going to be in the rear wheel, and we want to select the mirror plane as YZ.

02:49

Note that the operation is set to join. And if we say, okay, the result is three bodies.

02:55

We get this warning because we had two initial bodies that we mirrored, and it wasn't able to join them all together.

03:01

But we can use Modify and Combine to join Body 28, 27 and 26 together.

03:09

So the target bodies and the tool bodies don't really matter in this instance, but we want to make sure that we join those three together,

03:15

And now we have created our first obstacle.

03:18

That process took a little bit of time, and it was pretty cumbersome for us to do.

03:23

There are better ways that we can do this using some of the tools that we have at our disposal, such as Connector Obstacle.

03:30

When we use Connector Obstacle, we begin by selecting the start of the shaft.

03:35

In this case, the shaft is going in the wrong direction. So I'm simply going to bring it inward.

03:40

In this case, I want to make sure that I go at least 60 millimeters, and I want to extend past the boss We're going to be using to mount to our frame.

03:47

We're going to use bolt head, and we're also going to use Tool Clearance.

03:52

For the Bolt Head Diameter, we're going to set this diameter at 20 millimeters.

03:57

Then for our tool clearance, we're going to set the diameter at 30 millimeters, and we're going to set it to a distance of 50 millimeters.

04:06

We're going to say Okay,

04:07

and now we've created a new obstacle using that tool that was much quicker than creating our sketch in manually creating those entities.

04:15

Let's repeat that process by using our right click marking menu and go into the 12 o’clock position.

04:21

Once again, we'll select the Start, and we'll drag that in a distance of 60 millimeters.

04:26

We use Bolt Head and Tool Clearance.

04:29

Once again, we want to modify these values, the head diameter of 20 millimeters,

04:33

We'll set the tool diameter at 50 millimeters on the front, and we're going to set it to a distance of 50.

04:42

This tool is not going to remember our previous settings, and you can see that we have different values for the front and back.

04:48

What's important to note is what we're really doing here is we're defining the head of the bolt and how much clearance we actually need to get to it.

04:57

Keeping in mind that in most cases if we are going to have a hex bolt, for example,

05:02

then we would need to make sure that the diameter of the head clearance is large enough to accommodate the tool that we're using.

05:10

In this case, we're going to be using an Allen key or some sort of torques. So we don't really need to get all the way around the bolt head.

05:18

But keep in mind that it is important for us to remember that there are specific instances where we might need to increase these values.

05:26

Let's repeat the process on the other side noting that the orientation of this in relationship to our coordinate system,

05:32

means that we don't need to really make any adjustments. I'm just going to increase the length to 60 millimeters.

05:37

I'm going to add my bolt head at 20 millimeters, and then I want to add the tool clearance.

05:43

Once again the Tool Diameter, in this case, I'm going to leave at 35 millimeters on the back side, and I'm going to let it go 50 millimeters.

05:52

We'll repeat this one more time, once again, increasing this to 60 millimeters, adding our bolt head and our tool clearance.

06:01

Once again using those same values, I'm going to have the tool diameter equal to 50 on the front, and I'm going to have it extend 50 as well.

06:11

You might be wondering why the tool clearance is different on the front.

06:14

Well, in general, when you have a motorcycle, you might include other things such as frame sliders that would bolt to the frame,

06:23

increasing the tool clearance on the front is really more of a design aspect rather than getting the tool into that area.

06:29

Just means that we have enough room for adding additional functionality downstream.

06:35

There are more items that we need to create as obstacles.

06:38

But for now let's finish Edit Model, and let's take a look at what we have already defined as an obstacle,

06:44

and what has not been created as an obstacle.

06:47

Anything that we did with our Connector Obstacle Tool is automatically defined as an obstacle.

06:52

However, the ones we used with our Sketch Extrude and Mirror are simply just other bodies in the design.

06:59

So we need to go to obstacle geometry, and we need to add that element and say Okay.

07:05

So that's another benefit of using the Connector Obstacle is it easily and quickly makes his connector obstacles for us.

07:12

But it also preselects them as obstacle geometry.

07:16

There's one other area that we need to create an obstacle for the frame,

07:19

and that's going to be around the front section of the stem but I'm not going to include this in part of the course.

07:25

So feel free to try to create it on your own or we can pick up in the next design in the next video.

07:30

But make sure that you do save your work before moving on.
