Classifying Objects
To classify a drawing object, call ClassificationManager.Classify(). This tags the object with the name of the feature definition file and the feature class name. If the feature definition file is detached, the classification tag remains.
A single object may be classified more than once, by using feature classes from different feature definition files. To get a list of all classifications for an object, call ClassificationManager.GetAllTags().
To unclassify an object, call ClassificationManager.Unclassify().
To get a list of all objects in a drawing that have not been classified, call ClassificationManager.GetUnclassifiedEntities(). The result of this can be used to find and classify missing objects.
