In many CAD/CAM/CAPP applications, recognizing geometric features is of ubiquitous need. Recognizing and analyzing geometric features in a mechanical part will augment manufacturing knowledge within the product development process. Although feature recognition is progressing steadily in many computer graphics applications, it is still an undiscovered area in mechanical design; we are still lacking a feasible solution for feature recognition that can be applied specifically to the CAD parts. In this paper, we will present Shape Terra; our recent advance in CAD feature recognition technology. Shape Terra identifies the typical mechanical features from a given CAD part by utilizing the findings of traditional heat transfer theory, which says that salient features tend to retain the heat more whereas flat surfaces tend to lose it faster. Furthermore, each feature is analyzed and assigned with its meaning, such as design parameters, manufacturability, and so on. Various CAD/CAM/CAPP applications will profit from such information.
