Model Based Definition: Finally, the Engineering Drawing Killer?

Abstract

Engineering drawing has stood as the universal method of translating design intent since the first standard was formalised in 1927 as BS308. Further development of national and international standards has been informed by advances in CADCAM technology and the need for transfer of complex yet unambiguous definition between organisations. The emergence of model-based definition (MBD) has driven a new workflow where engineering drawing is no longer required. Instead, the dataset includes semantic, machine readable, tolerancing of surfaces and features for integration into manufacturing and metrology procedures. Despite the advantages of MBD, it has been largely ignored in UK higher education. However, MBD is the ideal method for teaching and learning geometrical tolerancing since it ignores the theoretically exact dimensions and housekeeping, concentrating on the functional limits. Further, it utilises the 3D workspace that students are increasingly familiar with.

Issues on Introducing Model-Based Definition - Case of Manufacturing Ecosystem

“…geometric tolerances with MBD require often the introduction of new knowledge. Investing in education on utilizing Model-Based Definition [20] can lower the barrier to adopt new methods. Also, the versions of software brands support certain standards of MBD representation while other versions do not.…”

Conceptualization of an artificial intelligence-assisted tutoring system for teaching technical drawing skills to undergraduate students

“…Technical drawings are the most common form of formalized component description in engineering and a central element in the development of mechanical components (Garland et al, 2017;Sampaio, 2018). They serve as an important means of communication between different disciplines and groups of people within organizations (Lille, 2013;Barr, 2004;Kosse, 2005).…”
