The AecSpaceOffsetClassification.Init method is defined as:
public void Init(Database database, Assembly assembly, CultureInfo culture, string
resBaseName, string classificationSetName)
The first 3 arguments are usually identical in all cases. The first one is the database to which the classification set needs
to be applied. The second argument is the current assembly that implements the standard plug-in. The third argument
is the localization for which the classifications are to be set up (in the example, the current setting of AutoCAD
Architecture is used, which is the recommended procedure). The fourth argument is the name of the string table within
the resources of the assembly. The last argument defines a name for the classification set in AutoCAD Architecture.
This should be localized too, because it will be visible to the user. However, this section focuses on classification handling
only. When running the standard with the resource file set up correctly, the drawing should now contain classification
definitions that apply only to spaces with the names defined in the resource’s string-table when the standard is assigned
to the drawing.

Using Classifications in the Rule Implementation
After adding classifications to the current database, you want to use them within area calculation standard plug-ins.
You are in principle able to determine the classification from a space that is passed to a rule with the existing AutoCAD
Architecture .NET API. This however could be complex, especially as you always need to use the global name of
classifications within your rules, in order to work with all localizations of the classifications display name. Therefore,
the class AecSpaceOffsetClassification provides functionality to simplify this.
Reading the Global Classification Name from a Space Object
The AecSpaceOffsetClassification class has a method to get the global classification name from a space object so that it
can be compared to the names defined by the resource string table to decide how to offset boundaries. The method is
the public string GetClassificationName(Object Id objId). The following example shows a bounding adjacency rule that
uses the classifications described in the example table above. Because the rule needs to be able to access the
AecSpaceOffsetClassification object of the standard, the standard is passed through the constructor and assigned to a
member of the rule. This means you will need to create the rule in the standard’s InitRules() implementation with a
“this” reference to the current standard.
