AutoCAD Crack [Win/Mac] (Latest)

Graphic user interface of AutoCAD 2020.

AutoCAD was originally based on the widely used FORTRAN programming language, but was later redeveloped using COBOL and is now based on the object-oriented programming language C++. The application and its design philosophy is best described as a part-workflow part-design tool for users who need to create design drawings in conjunction with computer-aided manufacturing (CAM) software applications. AutoCAD, together with its CAM siblings, is known by the acronym DWG (Drawing), or as a «DWF» file for other kinds of file formats that support 3D. The DWG file format has been optimized for CAD and CAM operations.

+5 Like Like AutoCAD

AutoCAD is a collaborative software product whose purpose is to provide the functions and features required for designing, drafting, and editing 2D and 3D drawings. The application is known as a part-workflow part-design tool because it provides a combination of workflows that allows both CAD and CAM functions to be combined and executed in a single computer program. Some users may find it difficult to understand and operate the DWG file format.

AutoCAD is written in C++, which is a powerful programming language, and uses a line-mode drawing engine and a GUI. It is not compatible with older Microsoft Windows operating systems, but is available for Windows 10, 8, 8.1, 7, Vista, and XP. The application can be used by both computer graphic users and those who use a graphics tablet and stylus.

Programming languages
AutoCAD Cracked Version supports many languages for its programming interface, including: AutoLISP, Visual LISP, VBA, Java, C#, Visual Basic, BASIC, Python, Ruby, C++, FORTRAN, Unix shell scripts, MATLAB, and Visual FoxPro. The development platform is based on COM technology, which is also used in other Autodesk products.

AutoCAD Cracked Version uses the COM object technology, which means that AutoCAD functionality can be extended by programming in AutoCAD ObjectARX-based interfaces. ObjectARX is a C++ class library, which was also the base for:
products extending AutoCAD functionality to specific fields creating products such as AutoCAD Architecture, AutoCAD Electrical, AutoCAD Civil 3D third-party AutoCAD-based application There are a large number of AutoCAD plugins (add-on applications) available on the application store Autodesk Exchange Apps. AutoCAD’s DXF, drawing exchange format, allows importing and exporting drawing information.

Mac OS and Windows support AutoCAD natively. Other major UNIX platforms, including HP-UX, Solaris, AIX, and Tru64, are supported via a port of AutoCAD.

Raster graphics

AutoCAD uses raster image files to store objects such as shapes, text, and symbols. It reads in and displays these raster image files, called images, as either color or black-and-white. Images may be created by the user or imported from another program.

Images may be converted between color and black-and-white, or saved to other raster formats. Also, images may be modified. They may be textured by mapping a color image to a texture map. Using texturing, the image is capable of displaying sharp edges, for example as seen in a relief map or a map of an architecture design, or textured smoothly, for example in a map of a planetary surface. By using different levels of texture detail, an artist can create the effect of distant mountain ranges or the texture of a sculpture.

AutoCAD may also create a variety of images with special effects such as 3D objects, and composite images. For example, it may automatically apply perspective, lighting effects, and shadows to an image. These effects may be configured using a menu-driven editor or a wizard.

3D graphics
AutoCAD’s 3D capabilities enable the

Codeigniter — How to use AJAX, JQuery, CSS3 and PHP together

Im trying to implement an AJAX form submission and notification into a Codeigniter application, the system is a survey form that the user completes via a pre-populated form.
So the form loads a list of items, and after each item is answered a simple yes or no checkbox appears below the item, the user can answer yes/no for the box or press submit to add the answer to a database table.
When the form is submitted the database is updated, the list is reset to a start page and the survey form shown with the new list of items.
I am able to do this successfully in static html by assigning a class to each list item, then using javascript to create a modal dialog box to store the answers for that particular item, however as im trying to implement this into Codeigniter i cant seem to work out how to call this in jQuery, I’ve seen that ajax can be used to communicate with the server side, and im sure that codeigniter is compatible with this but im unsure of how to implement.
If someone could help me out with some examples or code that would be appreciated.


Try to understand that there are two big layers here:

Your PHP Code, the only thing you have to do with that is to return what you want from your PHP Code.
Your Javascript Code. You only have to change your HTML and CSS, or other that you want to add with Javascript.

In your code, you can do something like this:
$(‘#start’).on(‘click’, function() {
url: »,
method: ‘POST’,
data: {
‘data_parameter’: value
