You can use physical simulation in animations to simulate physical interaction between objects. You can control how the part moves, and how other parts interact with your part, and you can set different physical properties for each control position.
You can only move one part or assembly at a time (per control point capture) if you want to simulate physical interaction in your animation.
You can change the physical simulation properties before or after you record a control position. To set the properties after you record a position, make sure you select Modify in the Snapshot section.
To change the physical simulation properties for a control position,
1. In the Define Animation dialog box, click the Consider Physical check box.
2. Move one part in the viewport. The Physical check box becomes available.
3. Select Physical and click Properties. The Animation Physical Properties dialog box opens and the current control position is displayed at the top of the dialog box.
4. Set the following options for the part that you move:
◦ Fix Line: Keeps a constant distance between the axis or line and the moving part.
◦ Fix Axis: The part will not rotate when it interacts with other parts.
◦ Fix Slide: The part will not slide around other objects.
5. Set the following options for parts that interact with the part you move:
◦ Fixed: Parts will not move when your part pushes against them. Your part will stop moving when it touches another part.
◦ Translational: Parts will move translationally when your part touches them.
◦ Free: Parts can move in any direction when your part touches them.
6. Click >> Capture Position <<. Now you can view the physical simulation. Continue to capture new positions as desired.
7. The Animation Physical Properties dialog box can remain open while you define or modify your animation. Click Close when you are finished changing the properties.
