Abstract
Building on the premise that quality is a complex and multifaceted concept, we advocate for the structuring of the concept of quality in engineering design parametric CAD modeling by using three hierarchical levels. The goal is to successfully parse whether CAD models are usable, reusable, and semantically rich. Our classification results from emphasizing three sequential objectives that the models must accomplish: (1) being free from geometric and topological errors, (2) being modifiable without causing regeneration errors that may hinder reusability, and (3) being able to properly convey design intent while enabling design exploration and enabling CAD models to become digital twins. In this paper, we elaborate on the proposed framework and discuss its implications. Our grouping facilitates the matching of the six dimensions, which cover all aspects of CAD quality, with the two more commonly considered aspects of usability and reusability. Additionally, it highlights the fact that the third level is generally ignored and that the three aspects must be arranged and considered in a sequential manner. Finally, it opens the door to further advances in the automatic quantification of parametric CAD quality.
