An Information Model for Presenting Multi-user Design Intents for Feature-based 3D Collaborative Designing

Abstract

Design intent is a kind of design knowledge which is contributive in 3D model re-use, 3D model retrieval etc. Capturing, presenting and storing design intent still remains a challenge. In this paper, we propose an information model to explicitly presenting design intents which are embedded in the collaborative designing process and in the ultimate complex artifact from multiple dimensions. To support the information model, a meaningful design operation sequence discovering method is facilitated along with a structured organization of design operations. To provide readable and understandable design intents presentation, a natural language generation method is proposed as well. Finally, the proposedmethods are tested in a prototype system with case study.
