Configuration Steps:

1. Define source coordinate system
2. Specify target coordinate system
3. Configure transformation parameters
4. Validate transformation accuracy
5. Apply transformation during export

Data Filtering and Selection

Use Case: Converting only specific data subsets

Filtering Options:

• Point Range: Convert specific point number ranges
