• Unit and Measurement

The model should use consistent unit and measurement across the project with default drawing units in millimetres (mm) with a precision rounded up to the nearest mm unit.

All floor areas and volumes should be presented in square metres (m²) and cubic metres (m³) respectively and rounded off to three decimal places.

All site areas should be rounded off to the nearest 0.1m² for site area less than 2,000m² and to the nearest 1m² for site area of 2,000m² or above in accordance with PNAP ADM-21.
