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.
