AutoCAD 2020 23.1 Download [Mac/Win] [Latest-2022]

AutoCAD Serial Key is used as a layout and drafting software application that can be used for the design of mechanical components (CAD/CAM), construction (CAD/CAM) and architectural visualizations (CAD/CAM). Its users can create 2D and 3D drawings and 2D and 3D models of any object. AutoCAD also includes a variety of drawing-related and management tools, such as templates, settings, profiles, and so on.

Key features

AutoCAD offers several features, allowing users to create 2D and 3D drawings, 2D and 3D models, and coordinate drawings. The following features are included:

Graphical user interface (GUI)

Autodesk has developed its own GUI, which combines the best features of its previous PenCAD/AutoCAD and Inventor platforms.

Database connectivity

You can connect to a variety of database formats. The popular Open Database Connectivity (ODBC) protocol allows for the integration of AutoCAD data with other database applications.


It is possible to work on more than one drawing in a single session. This allows you to efficiently manage multiple files that can be processed concurrently in the background while you are using the interface.

Flexible database

In AutoCAD, you can use several database formats: SQL Server, SQLite, Oracle, Microsoft Access, Sybase, and others.

Variable and non-variable datatype

It is possible to define your own data types and variables.

Multiple-language support

AutoCAD is available in more than 75 languages.

Information sharing

You can share all or a portion of your drawing with others via email or through file transfer or a server.

Dynamic 3D

It is possible to create and edit 3D models using three-dimensional wireframes, surfaces, and faces. You can use this feature to construct complex 3D models in a straightforward way.

Raster and vector

AutoCAD has the capability to convert the drawing data from 2D to 3D and 3D to 2D. This functionality allows you to get the best of both worlds, combining the beauty of 2D and the accuracy of 3D.


You can create your own jobs to execute actions at the time you specify.

Color management

In order to display drawings accurately and

AutoCAD 2020 23.1 Crack + Free

Draw Exchange Format (DXF) is a standard for storing vector drawing information. DXF is a common file format that is understood by all AutoCAD Crack Free Download versions. DXF files are also often used by other CAD software such as Vectorworks. DXF files are used interchangeably with AutoCAD’s native files, such as DWG or DGN, which are used as the native AutoCAD drawing format. The DXF format was developed by Autodesk and is commonly used for storing CAD drawings.

Operating systems

Autodesk AutoCAD supports several operating systems, including:
Microsoft Windows
web browser (with AutoCAD LT), as well as:
iOS and
Android (with AutoCAD Mobile apps)

AutoCAD uses a batch file named «acad.bat» as its main entry point, and acts like a CMD shell.

Development and support
The development team for AutoCAD, Autodesk, was first based in San Francisco, California and then in Bedford, United Kingdom, which remained the headquarters location for the development team until 2007, when the development team was relocated to Chicago, Illinois. Since then, Autodesk’s development team has been based in San Diego, California, where the company has its offices, and Atlanta, Georgia.

AutoCAD runs on Windows, macOS and Linux, and is available as a free and a commercial product. AutoCAD LT is free, but comes with limited functionality. AutoCAD’s development team created a set of open source components (such as the AutoCAD Raster Utility, ADImagery, AUTOCAD Animation) that can be used for users to do work outside the CAD tool.

AutoCAD LT can be purchased for a single user for $299.00 annually or $100.00 per year for commercial use. AutoCAD LT 2018 was released on February 13, 2018. On April 17, 2019, Autodesk announced AutoCAD LT 2018 with new features, including new 2D and 3D scalability, new suite of industry-specific tools and technology to help manufacturers plan, document and manage product development projects.

AutoCAD LT 2018 runs on Microsoft Windows, macOS and Linux. It uses the same underlying file format, DXF, as AutoCAD, and can be integrated with AutoCAD and other AutoCAD software products, as well as with third-party CAD

Analysis of nine common polymorphisms of the Fc gamma receptor IIIb (CD16b) and their impact on neonatal sepsis.
Fc gamma receptors (FcgammaRs) are involved in pathogen recognition and phagocytosis. FcgammaRIIIb (CD16b) is a low affinity receptor with limited capacity to trigger phagocytosis. We sought to analyze the influence of genetic polymorphisms in the CD16b gene (CD16/FcgammaRIIIb) on susceptibility to neonatal sepsis. Two hundred and sixty-three newborns with suspected sepsis were prospectively included. A total of 9 polymorphisms of CD16/FcgammaRIIIb gene were analyzed. Phagocytosis of opsonized bacteria was studied in peripheral blood monocytes. A CD16(c) surface density was determined by flow cytometry. The FcgammaRIIIb -131 C/T (rs17616) and -144 G/A (rs396991) polymorphisms were associated with higher risk of sepsis (p = 0.04 and p = 0.02, respectively). Other polymorphisms, particularly in linkage disequilibrium, were not associated with increased risk of sepsis. The CD16b-131 T/T homozygote was associated with a lower CD16b density (p = 0.01) and lower phagocytosis (p = 0.01). CD16/FcgammaRIIIb-131 T/T genotype is associated with protection against sepsis and lower CD16b surface expression. These observations are probably due to the observed linkage disequilibrium pattern, because the CD16b-131 T/T genotype is in complete linkage disequilibrium with a Y240X premature stop codon, which reduces the expression of the CD16b molecule on the cell surface and on the lipopolysaccharide-induced immunoglobulin receptor.Field
The present invention relates to a system for real-time detection of leaks in pipes.
Pipelines are used in a variety of systems, including gas and liquid transmission, transportation and storage, manufacturing, and other systems. For example, gas pipelines, which typically transport natural gas, provide the source of supply for households and businesses. Oil and gas pipelines carry crude oil and natural gas from the wellhead to refineries, or provide alternative sources

What’s New in the?

Save time with print production faster. See your CAD design go from computer screen to paper. Run design simulations on paper-printed pages.

Save time when adding to existing sheets. Easily add, change, and remove graphical annotations, annotations, and other design enhancements, then re-import your work back into your main drawing.

Generate design changes faster. Get a sense of how changes to designs will affect various sheet sizes without having to re-draw the drawing or add additional geometry.

Intuitively add annotation. Quickly place design annotations in your drawings. Drag on, mark, and drop.

Equip your drawing for design collaboration. Create multiple copies of your drawing with the new design copy feature. Or, send multiple independent copies of your drawings over the Internet to colleagues for collaboration.

Model-based drafting at its best:

Start modeling at the beginning of a project—at the beginning of your day. Recognize when you’re in a design mode, and then model the shape you need, work in the right context, and get to the next stage of the project with ease. (video: 1:35 min.)

Grouping features help you work smarter. Easily view, copy, edit, and delete groups and sub-groups, then use those views and groups in your drawing.

Clipboard features help you work faster. Quickly copy to the Clipboard any view you see, then paste to a different window, or copy again to add it to the drawing.

Delete unwanted components and elements from a model. Quickly get rid of details that don’t belong in the model or that have no purpose.
