AutoCAD Crack+ Free Download [32|64bit]
User interfaces
AutoCAD Crack Free Download has three user interfaces (UIs):
Graphical User Interface (GUI) for drawing geometry and editing it,
A Command Line User Interface (CLUI) for executing AutoCAD commands,
A Command Window (CW) for entering and executing AutoCAD commands.
To make the tools visible in the graphic workspace, an AutoCAD application window is displayed, where the user can also activate a task panel for functions such as file selection and window management.
In common with other graphical CAD applications such as Delphi, PTC Creo and Solidworks, AutoCAD supports a variety of workbenches and workspace types, in addition to the standard two-dimensional (2D) view.
Some of the major features of AutoCAD are discussed below:

file formats 
AutoCAD Cracked Accounts's file format is DXF (or DWG for Drafting), an application for exchange of drawings. It is designed for direct exchange of drawings between CAD programs. The DXF file format is an industry standard for electronic drawing exchange.
 Building information modeling 
Building information modeling (BIM) is a generic term for a family of data exchange formats. It is used to describe a set of standards for the exchange of building information used in the construction of buildings. It allows for 3-dimensional models to be created from disparate sources, and 3-dimensional drawings to be created by a CAD program. As such, it is considered to be a key component of the digital workplace.
BIM was originally developed in the 1980s. BIM is commonly represented as an XML based hierarchical structure with three key elements: the building model, a set of metadata and a set of nodes. The model may be produced by any of a number of CAD programs. Metadata is a descriptor of elements in the building model. Nodes are entities that represent something in the model.
The BIM data exchange format, such as BIM-LDD (BIM Level Data Document) or BIM-PTD (BIM Package Data Document), is an open standard for information exchange. It is provided by the international Building Information Modeling Initiative (BIM-I) and the model specification is maintained by the BIM Standards Committee.
 Examples of BIM 
BIM allows the construction of objects (for example, buildings) and elements (such as beams and pillars) from different programs and formats, and from different providers. In addition, the building model can be shared in the building object data exchange (BODEx) format.
 Modeling and design 
In AutoCAD, parametric modeling is used to describe an object to be built (or "brought up" to build) in three-dimensional space. The object is built as a combination of parametric entities, which are modeled as splines, curves, or polygons. The "extruded" geometry along the defined spline or curve is generated from the user's data and the model data, typically when the model is closed.
The user's data is provided in an information file, such as a drawing. The user's data is also used to generate data of the model, such as a level of detail (LOD) representation. LOD is a term used in model-
