Abstract
An approach is presented to define a family of objects in parametric
modelling. It avoids an inherent problem of boundary re-evaluation in current
parametric modelling systems. Even more important, it offers an effective way to
define the properties, or semantics, of a family of objects.
A family of objects is defined by a prototype feature model, including several
types of constraints to precisely specify its semantics. A family membership
test is used to check whether an instance corresponding to a particular set of
parameter values belongs to a family. The underlying geometric representation is
a non-manifold cellular model.
