|
There exist numerous design rationale systems that convert captured information into structured design rationale while providing rationale representation and retrieval . These systems woefully neglect the design rationale that is present in legacy CAD such as 2D drawings and 3D models . The dissertation addresses the issues that arise when dealing with the capture , representation and retrieval of design rationale from the 2D legacy CAD data , specifically the non -form related data (e .g . text and symbols ) . A definition for design rationale in the CAD domain is presented which forms the basis of the proposed approach . The approach uses a unique context -aware inference system to capture design rationale from legacy CAD data . A brief explanation of context is provided along with the advantages of using context for this task . The need and use of an inference system is detailed . Additionally a prototype system is implemented to address these issues from a software system point of view . A verification process is suggested that will validate the design rationale captured by the system to that captured by human re -designers . |
