A common way of implementing a standard is to define offsets between spaces depending on their classifications. Even though you can do this with the area calculation standard API described in the previous sections and through usage of the available .NET API from AutoCAD Architecture 2022 toolset, the Autodesk.Aec.SpaceOffsetRulesManager.AecSpaceOffsetClassification class provides some functionality to make the handling of classifications for offset calculations easier.
