In the 3D studio, there are several ways to start animation lines, customizable to meet production needs.

### **Here are the three main methods:**

**1. Immediate Start**

- **Description:** After clicking the "Play" button, the entire animation line starts immediately, and all elements begin executing their programmed tasks without delay.

#### **2. Event-Driven Start**

**Description:** Events are conditions that define the start or end time of an object or process.

**Defining Events:**

- Select an element that controls the start or end of another object or process.
- Specify after how many events the selected animation line should start.

**Example:**  
The next line starts only after the previous one has completed its tasks.

#### **3. Signal from a Specific Element**

- **Description:** Signals determine whether a specific element meets the conditions to activate the next animation line.

#### **Signal Functionality:**

- **Example:** In a quality control system:
    
    
    - If an element passes inspection ("OK"), a signal with a value of 1 is sent, activating the next line.
    - If an element fails inspection ("Defective"), a signal with a value of 0 is sent, blocking the next line. The defective element is redirected elsewhere instead of being further processed.

#### **Defining Probabilities:**

- Specify how often a certain signal should occur. 
    - Example: Set a 75% probability for elements passing and 25% for defects to control the production process more effectively.

### **Summary**

Each method allows for flexible control of animation lines in the 3D studio, enabling you to optimize workflows to meet the specific requirements of your production process.
