Abstract
This paper presents an approach to recognize features using intermediate part geometry data. Part geometry is defined by manifold dual model representation, namely, the boundary representation (Brep) and constructive solid geometry (CSG) tree. In the dual modeling system, the boundary of each primitive is split into two parts by a intersection edges. One of the split boundaries of a solid is joined with one of the two of the other solid to make a new solid. One of the two joined as the new solid is identified as feature by topological and geometrical properties. In this approach, features can be recognized by just matching a isolated set of faces (split boundary) with templates instead of searching. Moreover, the necessary volume (volume feature) can be generated based on the recognized feature (surface feature) using the split boundaries.
