Equipped with the right applications, a computer can be of great help in virtually any domain of activity. When it comes to designing and precision, no other tool is as accurate as a computer. Moreover, specialized applications such as AutoCAD give you the possibility to design nearly anything ranging from art, to complex mechanical parts or even buildings.
Suitable for business environments and experienced users
After a decent amount of time spent installing the application on your system, you are ready to fire it up. Thanks to the office suite like interface, all of its features are cleverly organized in categories. At a first look, it looks easy enough to use, but the abundance of features it comes equipped with leaves room for second thoughts.
Create 2D and 3D objects
You can make use of basic geometrical shapes to define your objects, as well as draw custom ones. Needless to say that you can take advantage of a multitude of tools that aim to enhance precision. A grid can be enabled so that you can easily snap elements, as well as adding anchor points to fully customize shapes.
With a little imagination and patience on your behalf, nearly anything can be achieved. Available tools allow you to create 3D objects from scratch and have them fully enhanced with high-quality textures. A powerful navigation pane is put at your disposal so that you can carefully position the camera to get a clearer view of the area of interest.
Various export possibilities
Similar to a modern web browser, each project is displayed in its own tab. This comes in handy, especially for comparison views. Moreover, layouts and layers also play important roles, as it makes objects handling a little easier.
Sine the application is not the easiest to carry around, requiring a slightly sophisticated machine to properly run, there are several export options put at your disposal so that the projects itself can be moved around.
Aside from the application specific format, you can save as an image file of multiple types, PDF, FBX and a few more. Additionally, it can be sent via email, directly printed out on a sheet of paper, or even sent to a 3D printing service, if available.
To end with
All in all, AutoCAD remains one of the top applications used by professionals to achieve great precision with projects of nearly any type. It encourages usage with incredible offers for student licenses so you get acquainted with its abundance of features early on. A lot can be said about what it can and can't do, but the true surprise lies in discovering it step-by-step.

AutoCAD 24.1 [April-2022]

Contents of this article

AutoCAD is a commercial computer-aided design and drafting software application. Developed and marketed by Autodesk, AutoCAD is first released in December 1982 as a desktop app running on microcomputers with internal graphics controllers.

The software program that is used to create a computer-aided design (CAD) is called a CAD program.

The term is loosely used to refer to a wide variety of computer-aided design and drafting applications. AutoCAD is one of the more popular CAD software programs.

AutoCAD is a combination of a computer-aided design (CAD) program and a drafting program, which is used to draw geometry, such as lines, arcs, circles, and polygons.

Some CAD software applications are sold in “standalone” form, but AutoCAD is a “networked” program, meaning it’s a part of a network. To access AutoCAD files, you must have an account on the network (it doesn’t cost anything) and a personal identification number.

The term “CAD” is also used to refer to other applications, such as a specific version of AutoCAD, or an open-source or freeware replacement.

AutoCAD History

AutoCAD began as a workstation graphics program. The first AutoCAD was designed to create drawings of mechanical and architectural objects.

In 1982, by the late 1980s, major desktop publishing companies were using AutoCAD, and the first AutoCAD software was used in a commercial printing environment.

AutoCAD 1.0: 1982-1983

AutoCAD 1.0 was developed by The Benjamin-Concepts Software Group. The initial version of the program was released in December 1982. In August 1983, to coincide with the release of the Macintosh, AutoCAD 1.0 was bundled with the first Macintosh computer.

The initial release of AutoCAD 1.0 for the Macintosh was a self-contained software product, sold for $695. In 1983, The Benjamin-Concepts Software Group changed its name to Autodesk.

AutoCAD 1.0 was notable for its Graphical User Interface (GUI) and its command-line model, in which the user entered commands at a command-line or text-mode console.

File format
The drawing file format was originally AutoCAD R14. The number of layers is 1 or 2. Layers are not associated with specific objects, meaning that they can be used for anything at any time. The original CAD format was line drawings, each line was to be drawn as a one-dimensional line, with each new line starting at the last end point of the previous line. Although 3D models are possible, and even implemented in many CAD applications, they were first implemented in AutoCAD in version R17.5. For a long time, all versions of AutoCAD had the ability to easily edit 2D CAD files, and even to create 2D CAD files from scratch.

The drawing format includes the ability to assign a color to any portion of the line. This was very useful in a number of ways, not only to denote certain shapes, but to change the color of a line as another line is drawn over it, for instance. Color separation was also used to model full-color polychromatic lines.

The drawing format is inherently a 2D format, and is not able to store any data related to the 3D plane or model. Since the 2000s, a new file format has become the dominant standard, the DXF or DWG format. Unlike the earlier file format, the DXF/DWG file format can store the information of the model and associated material and color values in 2D. This is useful for many reasons, but the primary reason is that the DXF/DWG format can be read directly into almost any CAD application.

As AutoCAD became more sophisticated and user-friendly, and particularly with AutoCAD 2013 and beyond, there has been a transition of users from CAD applications like AutoCAD that are intended to be used by design professionals and engineers to hobbyist CAD applications such as Inventor and Creo. These applications are far more powerful and versatile, and have a different interface and purpose than the earlier applications.

AutoCAD has also been available in the form of an add-on for Apple OS X. The add-on was discontinued in version 2013, but the command line interface for AutoCAD from the previous version continues to be supported in the current version. In 2015, Autodesk announced the availability of AutoCAD for the Linux platform. AutoCAD LT for Linux debuted in 2017, offering a reduced feature set.

PHP RegEx Regex limit decimal value

I am trying to limit the decimal value in a variable in PHP
For example, I am trying to limit the decimal value to 10.
If I put the decimal value as 12, it should give me a warning.

Warning: preg_match(): Compilation failed: group name must start with a non-digit at offset 3 in /home/content/46/10027046/html/automation/crawler/main.php on line 6

Here is my code
$value = ’11’;
if(preg_match(‘/^\d{1,3}$/’, $value)) {
echo “It’s good”;
} else {
echo “It’s a problem”;


Instead of using a regular expression to test for valid input, consider using the filter_var function instead. It will return false if the input isn’t valid.
echo “It’s a good number!”;
} else {
echo “It’s a problem”;

Also, don’t use a regular expression to parse floats; it will be slow, especially if the number is a float of thousands of decimal places.
EDIT: In your case, you’d probably want to ensure that the decimal is

Share links to other applications, and attach files to CAD drawings.

Shape-based annotation

Shape-based annotation lets you apply annotation to any object—not just existing text.

Insert shapes and use them to add geometric constraints.

Drawings have a new look, but your documents don’t have to—you can now customize the appearance of your drawings by changing any of the settings for the color, style, and appearance of lines, shapes, and text.

Quick design

Improve the design process with a new Quick Design tool that allows you to take an idea and quickly turn it into a design.

Use the Quick Design tool to create reference sketches and quickly organize and annotate to create design variations or prototypes.
