AutoCAD 2018 22.0 Crack + Activation
How AutoCAD is Used
AutoCAD is designed to work with complex geometric and graphical objects, and to be used in the professional environment. In addition to the standard drafting and design functions, AutoCAD offers a variety of specialized drafting tools and features to enhance the power of the application. The standard use of AutoCAD includes the following.
Creating, editing, modifying, and annotating objects
Designing for fabrication and production
Modifying the appearance of lines, curves, and surfaces
Designing for print
Creating and editing installation and documentation
Drafting and modeling electrical and plumbing layouts
Creating detail and assembling information
Reality Check
Generating high-quality, accurate drawings in minutes. AutoCAD includes a built-in reality checker that ensures that the drawing can be viewed by a human without distractions.
Creating Content
Content is a part of any CAD package. It is the collection of content that provides a graphical representation of an application environment. Content, whether text, blocks, sheets, and dimensions, is stored in the project files. The term content can also refer to the set of items stored within a certain area or component of the design space.
Drafting and Design Tools
AutoCAD's basic drafting and design tools include lines, arcs, circles, ellipses, polygons, and arcs, combined with basic geometry functions (area, centroid, center, circumference, and distance) and parallel, perpendicular, and symmetry functions. AutoCAD includes a variety of specialized drawing tools, including architectural and mechanical drafting tools, dimensional and archival information, annotation, and package tools. These tools enable you to effectively create quality drawings quickly and easily.
Architectural and Mechanical Drafting Tools
Architectural drawing, mechanical drawing, and electrical engineering drawing tools enable you to create documents that specify design specifications for construction projects. These types of drawings are used in the architectural, mechanical, plumbing, and electrical industries.
Dimensional and Archival Information Tools
Dimensional information tools are used to store and maintain a library of standard and custom size data and information. This data can be used when creating reference drawings, templates, and engineering models. Standard sizes, such as electrical, plumbing, and mechanical dimensions, along with standard symbols, are stored in this library and are commonly referred to as dimensional standards or Dimensional Markup Language (DML).

DXF
AutoCAD also has a text-based DXF file format. The DXF file format is used for 2D drafting, sketching and modeling. The DXF file format was introduced with AutoCAD 2002 and is based on the Electronic Design Interchange (EDIF) standard. The DXF file format is only used for internal communication and does not support external formats such as the SVG.
DXF files are text-based. They are composed of lines and blocks of geometric objects in the form of lines, curves, arcs and polygons. Each line is divided into two fields. The first is the linetype, indicating the type of the line, and the second is the line color. Both fields are optional. There is a third field that includes a group number. Lines in a block of text are stored in the order that they appear, and they are separated by a "tab" character.
The DXF structure is meant to be compatible with the "generic" design interchange standard used in the aerospace and automotive industries.
A new DXF file format
Autodesk is currently creating a new DXF file format (not yet publicly available) to replace the DXF file format. The new format was introduced with AutoCAD 2011 and allows for larger file sizes,  larger line widths and transparency, and more efficient support of characters and special symbols. In addition, the new format has an improved flow of text blocks. In the new format, text in blocks is stored alphabetically, with the "tab" character as the last character in the block, unlike the old format, which stores it as the first character in the block. It is recommended that designers switch from the old DXF file format to the new one.
DXF data and format overview
DXF data is transferred through the ASCII character set.
Line types are encoded as a combination of two values: the actual line type (LineType) and the end style (LineStyle). The combination of the LineType and LineStyle determines the basic properties of a line. The LineType value defines the line type, either a generic line (LineType is not specified, which is also referred to as a generic line), one of the four predefined line types (LineType values 1–4), or a special line (LineType is 35). The LineStyle value determines
