To define an animation,如何定义动画
Click Animation .
Click Define
To edit an existing animation, click Animation and select the animation in the Structure Browser.
To create a new animation, click New Anim. The New Animation section opens at the bottom of the menu panel.
Select an Owner in the Structure Browser. The owner must be:
An assembly or container holding all the objects and relations you want to use.
Writable, but objects such as parts or subassemblies below the owner can be read-only.
Type a Name.
The Attachment field determines whether the animation is saved in the Contents or Instance file. For more information about these files, read 3D Data files.
Click Accept. The menu changes to display the animation options.
Move objects in the viewport with the Position controls.
You can change the following options:
Click Selected in the Snapshot section to specify multiple objects.
Click Next to clear the selected objects list, or ResetPos to restore the initial or previous location of the control position.
Physical in the Rset/Physical section simulates physical interaction between two or more objects. See Physical simulation in animations.
Consider Physical turns physical simulation on or off while you play the animation.
Change the Insert Time if you want this segment of the animation to be longer or shorter. The default value is 1, which is one second.
Change Delta Time to slow the movement of objects.
Click Capture Position.
Repeat these steps until you are finished defining the animation.
非也，非也！
