Practical Notes
When setting up CAD or BIM templates, line types and weights should be mapped according to Table 3 to ensure standardized plotting.
Always use the standardized abbreviations from this code (e.g., 'GL' for Ground Level, 'DPC' for Damp Proof Course) to avoid on-site misinterpretations.
