This chapter provides an overview of Architecture SDK and gives information on the product's purpose, key features and structure.

ODA Architecture is an SDK (C++ dynamic link libraries) that allows working with Autodesk® Architecture® files from any application.

Structurally, Architecture SDK consists of several modules, containing classes, incapsulating architecture objects:

• AecArchBase — base architecture primitives: wall, window, opening, door, roof, stairs, etc., and auxiliary objects for them.
• AecArchDACHBase — dimension class and auxiliary objects for it.
• AecAreaCalculationBase — area class and area calculation algorithms.
• AecBase — base functionality for all architecture libraries and additionaly 2DSECTION, MASSELEMENT, MASSGROUP, AECPOINT, AECOLYGON classes.
• AecDummyLoader — used for dynamic loading of Aec-modules.
• AecExtensions — contains a set of different examples.
• AecGeometry — HLR algorithm, AecMesh.
• AecSchedule — AECDbScheduleTable class and auxiliary classes.
• AecScheduleData — AECDbPropertySet, AECDbPropertySetDef classes and auxiliary classes.
• AecStructureBase — AECDbColumnGrid, AECSDbMember classes.
• AecUIArchBase — grip points for common entities.
• AecUIBase — grip points.
• AecUISchedule — grip points.
• AecUIStructureBase — grip points.
• FacetModeler — implements boolean operations over 3D objects. Used by all other architecture modules.

To work with a class, a developer must load the corresponding module as a .tx file (dynamic configuration) or link the .lib file (static configuration).

Architecture modules will be automatically loaded if DEMANDLOAD variable isn’t disabled.
