In this paper we define a spatial symbolic model that can
be used to describe classes of 3­D objects (anatomical and
man­made) and a method for finding correspondences be­
tween the features of the symbolic models and point sets of
3­D mesh data. An abstract symbolic model is used to de­
scribe spatial object classes in terms of parts, boundaries,
and spatial associations. A working model is a mechanism
to link the symbolic model to geometric information found
in a sensed instance of the class, represented by a 3D mesh
