Assessment of 3D Annotation Tools as a Substitute for 2D Traditional Engineering Drawings in Aerospace Product Development (original) (raw)

2010, Computer-Aided Design and Applications

Reducing the costs of bringing a new product to market is an objective common to all industries. In aeronautics, one of the options being pursued to achieve this goal is to eliminate the use of traditional engineering drawings from the product development process-chiefly by integrating a portion of the information normally contained in these drawings into a 3D digital mockup (DMU). Before making this major change, several industrial practices must be revised and certain technological problems need to be resolved. One of the challenges is the transposition of the information found on traditional 2D engineering drawing, namely notes, dimensions and tolerances, to a 3D DMU. This article presents an evaluation of the feasibility of enriching 3D DMU with the aim of eliminating engineering drawings, based on the results of experiments in transposing samples of aerospace 2D engineering drawings to 3D environments using Catia V5 R17 SP6, a Computer-Aided Design software product. Experimental results show that placing annotations on the 3D DMU is feasible even for complex aerospace drawings. These results should help engineering design organizations decide if eliminating traditional engineering drawings is suitable for them.
