摘要

Context sensitive assistance is a new method to integrate design and manufacturing. Context sensitive assistance in computer aided design systems may be provided by recognizing design intent. In this paper, design intent is recognized for mechanical object categories based on a construction tree model. As the object is being created, a construction tree is simultaneously created that stores the object as a difference of volumes. If the construction tree model is recognized as belonging to a particular category then context sensitive assistance may be offered. Context sensitive assistance may include completion of a CAD model, retrieving detailed models from approximate models, design for manufacturability and assembly and providing detailed technical information. Gears are used as the mechanical object category in this paper. The methodology outlined can be extended to include other categories and may also be combined with feature recognizers for improve performance.
