Managing Design Changes for Multiview Models

Coordination of design changes is important because, if the design changes are not properly managed, design conflicts will result in more expensive design or even failure in the design-construction process. Geometric modification has been a routine for design activities. However, the facility of existing systems for managing changes in multiview models is still inadequate. This paper presents a novel parametric approach using a knowledge-based constraint solving method to incorporate the projection knowledge and graphic inference to address the issue of design changes for multiview models. A corresponding multiview constraint solver has been developed. This knowledge-based constraint solver can be combined with the linking knowledge between building components to facilitate the coordination of design information for multiview models. Illustrative examples are presented to demonstrate the feasibility of the proposed parametric approach for design change management.
