After completing this lesson, you'll be able to animate the motion of an assembly,
00:11
the visibility of its components, and the view position of the components.
00:17
You'll also be able to generate a rendered animation.
00:23
In addition to generating still images of a design, you can also capture the mechanisms of the design in motion.
00:31
In the Inventor Studio environment, you have access to an animation timeline.
00:39
On this animation timeline, you can specify the amount of time that you would like to animate the assembly,
00:44
and the actions that you would like to animate.
00:47
We'll begin by setting the duration or the length of the animation to 5 seconds.
00:56
Then, we'll want to start making changes.
00:59
First, let's animate the visibility of components over time.
01:04
We'll select the Fade tool.
01:08
Then, in the browser, select most of the components that make up everything but the gears and the primary sprocket.
01:18
We'll select all of the components up to the motor.
01:22
Then, we'll also select the two plugs and the bolted connection between them.
01:29
Finally, we'll select the stand.
01:33
We'll specify the amount of time we want the view transition to happen.
01:37
We'll begin the view transition at 0.3 seconds and finish it at 1.
01:44
As far as what we'll be animating, we'll take the visibility of the components from 100% down to 0.
01:56
When we click Okay,
01:60
we'll be positioned at 1 second, and we'll see all the components are invisible.
02:05
If we expand the timeline, we can see that a series of actions have been created for each component.
02:14
Returning the timeline to 0 and then clicking Play, we can see the components fade out over that time.
02:26
Let's return the timeline back to 0.
02:31
Then, let's get a different view of the assembly.
02:36
Want to focus in on the gearbox area.
02:42
And in the browser, we'll go up to Camera, right click, and select Create Camera from View.
02:53
Next, let's animate the camera.
02:58
There are many options that you have for animating a camera.
03:01
You can define a sketch for the camera to follow.
03:05
For this exercise, I'll use a simple turntable about the Z axis.
03:12
Make sure that it's rotating the correct direction,
03:17
and we'll say that what we want to do is 0.45 revolutions.
03:26
We'll start at 0 and complete the revolution at 4 seconds.
03:33
Clicking Okay, we can rewind and test the animation again.
03:40
What will happen this first time is we will see the camera move as the components fade.
03:48
Let's rewind again.
03:50
This time, let's switch the view from current view to Camera 1.
03:55
Now, when we play it, we'll see the motion of the camera as we see the components fade out.
04:05
Let's rewind one more time, and let's create an animation of positional representations.
04:14
In the assembly, there's a master positional representation.
04:18
But there's a second positional representation called Rotated Gears,
04:22
that rotates the gear set 540 degrees with the mating gears updating their position.
04:32
We'll specify the rotation of the gears beginning at 0.5 seconds and stopping at 4.8 seconds.
04:44
We can go to the acceleration tab and specify an acceleration.
04:51
For 20% of the animation, it will accelerate.
04:54
For 60%, it will run at a steady speed, and then it will decelerate for the last 20%.
05:01
We'll click Okay to create the animation.
05:05
Now, let's rewind and test again.
05:09
We can see that the gears rotate, the camera repositions, and the components fade out.
05:15
Now, we can use the Render Animation tool using many of the same options we had for render image.
05:24
We can select a resolution. We'll get a preview of what the frame will look like.
05:31
We can choose what the output will be, setting the appropriate time.
05:38
If we want this to be a video format or a series of images,
05:45
and specify the output area, the frame rate, and how we want to render it.
05:53
We can set a total rendering time, set a number of iterations to render.
05:58
Let's set this to 15 and then set the quality level.
06:03
Similar to ray tracing or render image, we can use high, draft, or low.
06:09
Let's just use low for this example, and let's start the render.
06:15
We'll start the render, selecting where we want the file to go, and choose the file type to be wmv or avi.
06:24
We'll start the avi by clicking Save.
06:30
We'll set the codec, click Okay, and it will begin to render the individual frames for this animation.
06:52
When the rendering is completed, you can save the file.
06:56
Note that even with the low frame rate of 15 frames per second and the low quality rendering,
07:03
it can still take significant time to generate the animation.
07:10
Even with the modest quality output, you can see what the potential is.
07:19
As a demonstration of what's possible with a little more time and a higher quality rendering,
07:24
let's take a look at this example done at 20 frames per second with a high quality rendering.
07:32
Being able to share your designs with the world in a clear and concise manner in a relatively simple way,
07:38
is an incredibly powerful capability to add to your skill set with Inventor.
