Gravity

---

Support adding gravity to the entire assembly to simulate the effect of gravity on the motion simulation.

How to use：

1. Open the Motion analysis and click the Gravity command.

2. You can define the direction of gravitational acceleration using a 3D coordinate system, or select a geometric element as needed to define the direction.

3. Enter the acceleration value.

4. Click OK.

Note： Gravity is typically used in conjunction with motors, forces/torques. When defining gravity using a 3D coordinate system, there's no need to pick geometric elements.
