# Quick Configuration Reference

## Change NX Version (e.g., when NX 2506 is released)

**Edit ONE file**: [`config.py`](../config.py)

```python
# Line 14-15
NX_VERSION = "2506"  # ← Change this
NX_INSTALLATION_DIR = Path(f"C:/Program Files/Siemens/NX{NX_VERSION}")
```

**That's it!** All modules automatically use new paths.

---

## Change Python Environment

**Edit ONE file**: [`config.py`](../config.py)

```python
# Line 49
PYTHON_ENV_NAME = "my_new_env"  # ← Change this
```

---

## Verify Configuration

```bash
python config.py
```

Output shows all paths and validates they exist.

---

## Using Config in Your Code

```python
from config import (
    NX_RUN_JOURNAL,       # Path to run_journal.exe
    NX_MATERIAL_LIBRARY,  # Path to material library XML
    PYTHON_ENV_NAME,      # Current environment name
    get_nx_journal_command,  # Helper function
)

# Generate journal command
cmd = get_nx_journal_command(
    journal_script,
    arg1,
    arg2
)
```

##  What Changed?

**OLD** (hardcoded paths in multiple files):
- `optimization_engine/nx_updater.py`: Line 66
- `dashboard/api/app.py`: Line 598
- `README.md`: Line 92
- `docs/NXOPEN_INTELLISENSE_SETUP.md`: Line 269
- ...and more

**NEW** (all use `config.py`):
- Edit `config.py` once
- All files automatically updated

---

## Files Using Config

- ✅ `optimization_engine/nx_updater.py`
- ✅ `dashboard/api/app.py`
- Future: All NX-related modules will use config
