The parametric and traditional CAD approaches are fundamental for pattern construction. This paper empirically analyses their geometric data entry, construction space, methods, workflow, and outputs, highlighting differences between the two. The results show that the traditional approach offers faster data entry but lacks editability, while the parametric approach prioritises data modification efficiency despite requiring more time for initial entry. The traditional approach allows quicker construction but becomes time-consuming for significant pattern changes, whereas the parametric approach, although slower to construct, offers editable blocks for efficient modification. The parametric approach captures both geometric shapes and block logic, in contrast to the traditional approach's focus solely on geometric shapes. The parametric approach supports the creation of custom garments, reducing waste and promoting sustainability, while the traditional approach leads to static blocks necessitating recreation for each new wearer. Accordingly, educational institutions should spearhead the transition to the parametric approach.
