AutoCAD 21.0 Crack Free Download

The first version of AutoCAD was developed by a team of 60 software developers from a Cambridge, MA area called Camargo, Lerer, Huber and Associates (CLH Associates). After four years of development, the first version of AutoCAD was released in December 1982. The CAD industry, including manufacturers, architectural firms, contractors, and designers, estimated that the time to produce AutoCAD was about four years. In September 1988, AutoCAD V1.0.4 released. With this release, Autodesk completely changed the way in which CAD is run. This effectively created a whole new CAD market.

The introduction of AutoCAD was one of the most important events in the history of the CAD industry.

AutoCAD has been widely used in various industries. According to the AutoCAD Products 2018 Web Benchmark, AutoCAD was the No. 1 most popular CAD product on the web with an average user time of less than a minute.


AutoCAD is an application that allows users to draw and draft 2D and 3D objects. The primary features of AutoCAD are its user interface, which is platform independent and easy to use. With its 2D drafting feature, AutoCAD allows users to create, modify, measure, and annotate drawings. With its 3D modeling feature, AutoCAD allows users to create 3D models and visualize them using 3D visualizations.

AutoCAD is used to build the design of large-scale infrastructure projects such as freeways, airports, and subway stations. Because of its extensive collaboration capabilities, AutoCAD is being used by global design teams to build large-scale architecture projects for clients.

AutoCAD is mainly used by architects, civil engineers, mechanical engineers, industrial designers, and surveyors. It is also used to create blueprints for construction and electrical projects.

AutoCAD History and Overview

AutoCAD started out as a desktop application in 1982. AutoCAD was developed by the Camargo, Lerer, Huber and Associates (CLH Associates) team. The software was first launched in December 1982, and was first designed to run on internal graphics controllers. Before AutoCAD was introduced, most commercial CAD programs ran on mainframe computers or minicomputers, with each CAD operator (user) working at a separate graphics terminal.

The development team consisted of

Functional programming

AutoLISP is an ObjectARX Application Programming Interface, so a plugin can be developed in this language. AutoLISP supports various types of subroutines which in turn can be exported as a dynamic link library (DLL) or a shared object (.so) file. Some examples are the functions Evaluate, FindFirstLineOfText, MoveCursor, etc. These functions are called from a host program and are able to read and write directly from and to specific parts of the internal memory of AutoCAD. This functionality may be used in places where access to the temporary memory is required, but are not allowed in the memory used by the AutoCAD application itself.

Visual LISP
Visual LISP is an ObjectARX Application Programming Interface, so a plugin can be developed in this language. The Visual LISP code must be written in the XLIMC object extension language.

Language documentation
The programming language documentation for AutoCAD is available online through the Help menu (?).

How to recursively enumerate all directories on an IFS mounted node?

I am trying to write a script that creates directories based on the value of IFS (FSHARES) in the current directory (i.e. /home/user/FSHARES) and recursively for every possible directory it finds. I have set up a loop that enumerates the possible values of FSHARES, however I can’t figure out how to create the directory name for each directory as the FSHARES value changes. I have tried putting a recursive loop inside of a for loop, however that does not work.
Here is what I have so far:
while read -r -p “Select a FSHARES value: ” name
for each dir in /home/user/FSHARES
echo “$dir”
mkdir /home/user/${dir}
done ,  ()](\doibase 10.1103/PhysRevA.83.063826)

What’s New In AutoCAD?

You can import markup directly from Adobe Photoshop, Adobe Illustrator, InDesign, and PowerPoint.

Import feedback directly from an AutoCAD sheet into the drawing to facilitate design review, and vice versa.

Incorporate the most recent version of your design in other drawings with a single click.

Include a preview of the information from the markup import or assist in AutoCAD to facilitate design review.

Markup Assist is automatically activated when you import information from other AutoCAD applications or from paper and PDFs.


One of the most powerful new features of AutoCAD is its ability to rasterize images directly into your drawings. Instead of using layers, you can draw on top of the source image and the source image becomes your new drawing layer. (video: 1:13 min.)

High-dynamic range color:

Printing with consistent colors, contrast, and hue is easy. AutoCAD 2023 supports new CMYK inkjet printer profiles, including printing of Pantone colors. AutoCAD creates CMYK prints using a standard, non-destructive ICC color model. (video: 2:12 min.)

Retouching of drawings:

With the new retouching feature in AutoCAD, you can add colors, lighting, or other changes to a drawing for a better looking rendering. Select which changes you want to make and you can even save the changes so you can apply them later.

Real-time coordination with Microsoft Project and Google Docs:

The new collaboration and connection features in AutoCAD 2023 are designed to help you work together easily. Sync your project plans with the latest changes on the drawing and see how they will be reflected in your design review.

Direct printing from AutoCAD of pages from AutoCAD files or from a web browser using a 3D view. (video: 1:11 min.)

New print preview capability to compare your plan to the actual drawing.

You can also directly print any drawing using an image file.

Printing of plans from a browser or cloud service, such as a browser-based Google Docs application.

You can also import the latest version of your drawing directly into a web browser or cloud service, such as the new Microsoft Project application.
