DWG files from AutoCAD Architecture (formerly Architectural Desktop or ADT) often contain additional information, such as special objects, material definitions, and styles. 3ds Max is thoroughly compatible with AutoCAD Architecture, and it recognizes all of these specialized objects and definitions during the file link process.
Each instance of an AutoCAD Architecture (formerly Architectural Desktop or ADT) object is represented by multiple objects in 3ds Max. Whenever the file link process detects a useful distinction between elements of an AutoCAD Architecture object, it automatically separates, names, and groups the elements in 3ds Max to make them easier to work with.
Materials in 3ds Max are vital to making your visualizations compelling and realistic. The native material attributes that 3ds Max relies on are those that tell it how to render the surface of an object given certain lighting conditions. Those material properties that are so central to architectural visualization (that convey surface coloring, surface texture, transparency, and so forth) are only one of many sets of properties covered in an AutoCAD Architecture (formerly Architectural Desktop or ADT) material definition.
