# Best Practices
## Best Practices
### Format Selection
1. **STEP**: Best for 3D geometry exchange
2. **IGES**: Legacy support, use STEP when possible
3. **DXF**: Best for 2D CAD interoperability
4. **STL**: 3D printing and visualization only
### Conversion Quality
1. Always verify dimensional accuracy after conversion
2. Check for missing entities (arcs, splines, text)
3. Validate layer structure preservation
4. Test with small sample before batch processing
### Automation
1. Use Python scripting for repeatable tasks
2. Create conversion templates for standard workflows
3. Implement quality checks in CI/CD pipelines
4. Document conversion parameters for reproducibility
