AutoCAD Civil 3D







AutoCAD 2020 23.1

AutoCAD is a proprietary program of AutoDesk, the company founded by Maxfield Parrish, and makes use of the Windows operating system and numerous, freely-available AutoCAD plug-ins. (The plug-ins allow AutoCAD to communicate with a variety of software programs and hardware devices.)

Program features

AutoCAD offers a number of features for computer drafting and drawing. In the professional version, users can combine computer-aided drafting, or CAD, with the Autodesk 3ds Max modeling software to create 3D models. The Express and student versions of AutoCAD support 2D and 3D drafting only. There are a wide variety of modules (pre-installed or user-installed) that provide support for specific features.

Many of the common features in AutoCAD are used with other software programs as well. Most of the common features can be enabled or disabled on the user interface. For more information on these features, see the feature article in the AutoCAD feature table. The table can be used to select features to search and see which AutoCAD modules provide support for those features.

For more information on features available in AutoCAD, see the feature article in the AutoCAD feature table. For more information on installing plug-ins, see the plug-in feature article in the AutoCAD feature table.


For information on the accessibility features of AutoCAD, see Accessibility.

Supported file formats

AutoCAD is able to open and save files in the following file formats.

Note that not all file formats are supported by every module. For more information on supported file formats, see the module feature article.


Adobe formats: PDF, SVG, XREF

Windows bitmap formats: BMP, GIF, JPEG, PCX









Bitmap (BMP)

AutoCAD will be able to open and export bitmap files, including PDML files created with PTC Creo. These files can be scaled for printing or digital use. The maximum size of the exported image is 4 GB.

The DXF file format provides for structural layouts and schematics of the drawings. It is capable of representing many design elements of the mechanical, electrical, or civil engineering drawings.

AutoCAD has a system called DBASE, which is based on SQLite. In AutoCAD, this system is used for storing drawing information. It is limited to 1822 drawing files. It is also used for storing creation information, object properties, and drawing layers.

File format

AutoCAD uses a proprietary file format named the AutoCAD Drawing Exchange File (ADX) format. Drawings in this format are in the Portable Network Graphics (PNG) format and are built with the DBase database system, which is similar to SQLite.

The ADX format is also used for exchanging files between applications.

AutoCAD uses a licensing system that requires users to purchase a perpetual license (in one, two, three or four concurrent installs on the computer), or a time-limited license (which expires when the software is no longer used for five or ten years, depending on the version). A perpetual license may be called a “Workstation license”. A computer is said to have one or more “Workstations”.

Time-limited licenses may be called a “Personal License” or a “Laptop License” (in multiple concurrent installs).

On August 21, 2012, Autodesk announced the availability of AutoCAD LT (no longer available) in a perpetual license version. This new license will still allow users to use the software for ten years without the need to renew their license. The permanent license will be replaced by a new license model sometime in 2013.

The perpetual license model was criticized by commentators such as InfoWorld, and the model was altered in 2013.

The following table lists the cost of each version of AutoCAD according to the current prices as of October 2019. The prices for each version are given in US dollars (USD) and in British pounds (GBP).

Model summary

AutoCAD 2016, the newest model of AutoCAD, was released in January 2016.

In 2019, Autodesk reported that the installed base of AutoCAD was at more than 50 million licenses. However, the installed base can be estimated at about 75–80 million due to the growing number of new license users as a result of renewals and upgrade cycles.

Why should you use autocad keygen software to generate an autocad key?

The autocad keygen software can be used for many purposes. Firstly, you may need to make a copy of an existing key.
Secondly, if you forget the original key, you can use the autocad keygen software to generate a new autocad key.
Thirdly, you can use the autocad keygen software to create a unique autocad key for your autocad.
Finally, if you use the autocad keygen software to generate a new key, you can always keep a copy of it safely.

You should never generate a key just for self use. It is strongly recommended that you print a copy of the generated key.

What’s New in the AutoCAD?

As you turn your mind to the future of AutoCAD 2023, you may also have one or more other thoughts on your mind: Is this the year I will finally start that drawing I’ve been itching to make? Will that paper pattern I printed finally help me with that kitchen renovation? And if the answer is no, what now? In the new, upcoming year of AutoCAD 2023, we’re offering a preview of the improvements to give you a head start on what to look forward to. In this new video, you’ll see a look at new Markup import and Markup Assist. Watch this video for an overview of new features and capabilities, or read on for a more detailed look.

New Markup Import and Markup Assist:

Rapidly send and incorporate feedback into your designs. Import feedback from printed paper or PDFs and add changes to your drawings automatically, without additional drawing steps. (video: 1:15 min.)

The New Markup Import and Markup Assist feature allows you to import feedback from printed paper or PDFs and add it to your drawing.

Included are:

Over 500 “markup tags” that can be applied to drawings. You can add your own tag controls or automatically add tag controls based on a subset of your design.

Tag controls are added to the drawing through any tag-able object, including lassoed objects, paths, and polylines. If the object is tagged, the tag control’s options are available.

The Export dialog gives you options to export the tag controls to an Excel spreadsheet and to email the tags to your team.

If you have a computer or mobile device with a text-to-speech device, you can listen to the markup imported by the feature.

If you want to share feedback with others outside of your company, you can include an object in the markup that is tagged with the object’s XREF and attach the XREF to an email.
