Abstract
Current feature-based modelling systems fail to adequately maintain feature
semantics. This is partly due to inappropriate specification of validity
conditions in feature classes, but mainly due to a lack of effective validity
maintenance mechanisms throughout the modelling process.
An essential aspect in this is feature interaction management. This paper
presents a new approach to the detection of feature interactions, which uses
semantic and interaction constraints in feature class specification. Validity
maintenance is automatically performed after each modelling operation by
checking these constraints, thus being able to detect a variety of interaction
types. Such interactions are then analyzed, and their causes identified and
reported to the user.
