“…Although they solve inconsistency problems between CAD view and geometric dimensioning and tolerancing view or manufacturing view, their approach focuses on repairing models with only constraint. While analysing the tolerance between two entities, Deshpande et al (2000) used a model object tree to evaluate the topological entities of a B-Rep model. After approximating the exact B-Rep shape as a polyhedron of a faceted B-Rep, Barequet et al (1996), Barequet (1997), and Steinbrenner et al (2001) repaired the gap and overlap that occurs between polygons.…”

Digital representations of products are replacing physical drawings as the main form in which product data are stored, analysed, and communicated among those who contribute to the design of automobiles. Because many engineers and companies participate in the complex design of automobiles, the design process depends on the team members' ability to share information on essential design elements. These trends have elevated the importance of the quality of digital product data and its efficient exchange. We review the state of the arts for product data quality (PDQ), as well as 3-D model quality assurance systems for the PDQ improvements. We propose a method for diagnosing and repairing CAD model errors based on the design history.

“…Hoffman and Robert (1998) checked the errors in the aspect of geometric dimensioning and tolerating (GD&T), and corrected them through procedural design history information. Deshpande et al (2000) used complementary model object tree for evaluating topological entities of a B-Rep model to analyze the tolerance between two entities. After approximating the exact B-Rep shape as a polyhedron of the faceted B-Rep, Barequet (1997), Barequet et al (1996), Steinbrenner et al (2001) and Volpin et al (1998) repaired gap and overlap that occurs between each polygon.…”

But imperfect interoperability imposes costs on the industry due to higher costs of design and production and slower implementation of design changes. In this paper, we propose a procedural approach to inspect the CAD model's errors that occur in a neutral format. We employed two separate inspection processes for checking CAD model errors without wasting excessive resources: the topological data structure and the geometrical data structure. We developed the 3D CAD model inspection system to check the topological and geometrical errors and applied it to case study. An inspection record can be edited in HTML, and thus can be shared by any designer at any time.
