Abstract
This paper presents a qualitative spatial model for manufactured
components capable of supporting systematic spatial inferencing about
the component. The model incorporates the features of the component
as well as mathematical spatial relationships between the
features. With the incorporation of these spatial relationships, the
model is capable of supporting spatial inferencing tasks of benefit to
the planning phases of manufacturing. As one example spatial
inferencing task, this paper describes how to find the multiple
interpretations of a component.
