AutoCAD Crack Product Key
A physical AutoCAD document can be edited in any application that can read the.DWG (AutoCAD Drawing) file format. Although AutoCAD is primarily designed to be used in a graphics mode, it can also be used in a typical text mode as long as it supports the AutoCAD object information format (AOI). AutoCAD can also be used with the DWG Express Add-in and in an interactive mode with the AutoCAD Web Add-in.
One of the many functions of AutoCAD is the ability to draw AutoCAD objects and to manage them using the Object Manager window. A library of common and user-defined objects is included with AutoCAD, which can be organized into groups called "libraries." The Object Manager window allows the user to manage all objects within a library and to share those objects with other libraries.
AutoCAD also has a set of commands that the user can issue, which are executed either in a graphics or text environment. Most of these commands can be initiated from the Object Manager window, and are accessed by typing the command name or selecting it from a menu. Commands are divided into groups that are similar in function. To access a command in AutoCAD, the user must first select it in the Object Manager window and then select the command name in the command group that it belongs to.
Other features of AutoCAD include the ability to edit DWG files using native Windows editing programs such as Notepad and Textpad, as well as using other editors that support the AutoCAD object and feature information format (AFIF) file format. Autodesk has included many of the common and user-defined objects that are commonly used in construction projects into the available library of objects.
Some of the common AutoCAD objects that are included in the standard AutoCAD library are:
- Align
- Arc
- Bounding Box
- Center
- Drafting Tools
- Dimension
- Drafting Window
- Ellipse
- Extrude
- Group
- Guide
- Multiply
- Outline
- Perspective
- Polyline
- Polyline Arc
- Polyline Rectangle
- Polyline with Edges
- Projection
- Pyramid
- Quadrant
- Rectangle
- Reference Line

Before 1985, AutoCAD Activation Code models were in a DXF-format. This means that the drawing could be exported to a drawing host application or another software application (from Adobe Illustrator to QuarkXPress).
Introduced in 1985, Raster Graphics Exchange Format (RGF) was an IFAX-like format for exchanging drawings. It was a popular format for communicating AutoCAD drawings until the introduction of DXF in 1985. The company developed the RGF format for that purpose, but it is not actively supported by Autodesk. The RGF standard has been preserved at the IFAX Forum.
Some other drawing formats, used in past versions, include:
 Vector Graphics Exchange Format (VGF)
 EPS
 PDF
 PostScript
 Scalable Vector Graphics
Vectorization
Rasterization
Partitions and drawing layers
A polyline is a line segment, in which endpoints are ordered. If endpoints of a line segment are not ordered, then the line is an open polyline. When the line segment is closed, its two endpoints coincide. An open polyline is not closed until the following command is executed: end polyline. Lines are connected to each other via the "Line to Line" command. In a few specialized applications, the command is called arc: arc from point to point.
Polylines can be grouped together with the "Group" command. These can be grouped into objects such as circles or arcs. Another way to group polylines is the "Block" command, which creates the basic block structure, which can be subsequently modified.
A closed curve is a closed polyline, which can be used for polygon, arc, circle or ellipse.
An open curve is a closed polyline, which can be used for polyline, arc or spline.
A polygon is an outline of a closed shape, which can be used for circle, ellipse or polyline. It is defined by a list of line segments in the drawing. A closed polyline is a polygon with no vertices. An open polyline has a starting point and an ending point, and is closed if the points are coincident.
A shape is any closed object. Lines, curves, arcs, circles and other shapes can be used to create each other.
A section is a non-closed polyline, which can be used to create a closed shape.
