# Orcaflex Line Wizard

## When to Use

- Setting up mooring lines with target pretensions
- Configuring riser lines with specified top tensions
- Calculating line lengths for given tension targets
- Calculating tensions for given line lengths
- Multi-line mooring system configuration
- Initial model setup before detailed analysis

## Python API

### Basic Line Setup

```python
import OrcFxAPI

# Load model
model = OrcFxAPI.Model("mooring_model.dat")

# Configure Line Setup Wizard
model.general.LineSetupCalculationMode = "Calculate line lengths"
model.general.LineSetupMaxDamping = 20  # For numerical stability


*See sub-skills for full details.*
### Comprehensive Line Configuration

```python
import OrcFxAPI
from dataclasses import dataclass
from typing import List, Optional

@dataclass
class LineSetupConfig:
    """Configuration for a line in the setup wizard."""
    name: str
    target_variable: str = "Tension"  # "Tension" or "Length"

*See sub-skills for full details.*
### Line Section Configuration

```python
def configure_line_sections(
    model: OrcFxAPI.Model,
    line_name: str,
    sections: list
) -> None:
    """
    Configure line sections with multiple line types.

    Args:
