 * __BIM (Building Information Modeling) Update__**

- a term coined by Jerry Laiserin, that we all can use for this process: BIM, or Building Information Modeling.

-BIM ->It's about information use, reuse, and exchange, of which electronic documents are just a single component.


 * The NCS defines standards for many aspects of electronic building-design data, including:**
 * CAD layers
 * Organization of drawing sets
 * Drawing sheets and schedules
 * Drafting conventions
 * Terms and abbreviations
 * Graphic symbols
 * Notations
 * Code conventions
 * Plotting


 * The National CAD Standard.** The NCS is a product from the cooperation of the AIA, CSI, and NIBS. The NCS represents a consensus among architects, engineers, and experts from the construction industry about how to classify building design data and streamline communication among owners and design and construction project teams based on paper-centric information delivery.

****The IAI IFCs (Industry Foundation Classes)****

The intention of the IAI is to specify how "things" that could occur in a constructed facility (including real things such as doors, walls, and fans as well as abstract concepts such as space, organization, information exchange, and process) should be represented electronically. These specifications represent a data structure supporting an electronic project model useful in sharing data across applications. The 2D graphics represented by the NCS is a subset of this model information.

Each specification is called a "class." The word "class" describes a range of things with common characteristics. For instance, every door has the characteristics of opening to allow entry to a space; every window has the characteristic of transparency so that it can be seen through."Door" and "window" are names of classes.

The classes defined by the IAI are termed Industry Foundation Classes (IFCs) for the following reasons:
 * IFCs are defined by the AEC/FM **industry**.
 * They provide a **foundation** for the shared project model
 * They specify **classes** of things in an agreed-upon manner that enables the development of a common language for construction.
