# Physics Simulation

You can use physics simulation to place objects in a natural state.

## Step 1 - Open Menu

* Press the **Physics** button to open the menu.

## Step 2 - Select Object

* Select the objects you want to simulation.

## Step 3 - Simulation

* **Physics 3D** Simulate 3D objects with physics.
  * **Auto Attach Physic component** If an object doesn't have a physics component, it will temporarily attach a component for simulation. If the component is already attached, this option will be ignored.
  * **Gravity** Specifies the direction of gravity.
  * **Camera Direction** Set the direction of gravity to the camera's direction.
  * **Simulation** Physics simulation is ongoing while the button is pressed.
* **Physics 2D**  Simulate 2D objects with physics.
  * **Auto Attach Physic component** If an object doesn't have a physics component, it will temporarily attach a component for simulation. If the component is already attached, this option will be ignored.
  * **Gravity** Specifies the direction of gravity.
  * **Simulation** 2D Physics simulation is ongoing while the button is pressed.

## Step 4 - Check the results

* Make sure you get the result you want.&#x20;
