FIELD: information technology.SUBSTANCE: user gesture indicating an edit to be performed on at least one target object within a model is received, the model being based on an underlying scheme including one or more constraints which define relationships between objects. It is determined whether at least one of the constraints in the underlying scheme is associated with the indicated edit of the target object. An indication of at least one valid version of model editing is provided to the computer user. It is determined, based on constrains associated with indication of editing which must be performed for the target object, that the model editing corresponding to the user gesture is invalid or it is determined, based on constrains associated with indication of editing which must be performed for the target object, that the model editing corresponding to the user gesture is valid. An indication of at least one valid version of model editing is provided to the computer user based on determining validity.EFFECT: simple process of model editing by the user.18 cl, 7 dwg |
