AutoCAD 23.1 Crack [Mac/Win] 2022 [New]







AutoCAD Crack+ Free PC/Windows

Computer-aided design (CAD) is a method of creating geometric shapes, and 3-dimensional (3D) drawings. Typically, an input device with a stylus, such as a mouse or pen, is used to make points or draw lines on a drawing tablet. A software application called a CAD program reads the input and creates a computer model. A 3D printer then creates a physical representation of the model in 3D. The printer and the original drawing are used to make the parts or components that are needed.

AutoCAD Crack Mac is both a CAD program and a drafting software application. A drafting program is designed to help create standard architectural drawings. These drawings include information about an object’s exterior, interior, materials, and measurements. When complete, a drawing is sent to a computer-controlled plotter, which then prints a physical copy of the object.

An AutoCAD user works in an environment where they input commands and make changes to the model. The output of these changes is usually a plotter or an electronic version called a DWF that is used by other applications. A key feature of AutoCAD is the ability to view, modify, and modify the model in different viewpoints.

An AutoCAD drawing is composed of layers. Layers and objects on a layer can be merged to a new layer.

There are different types of layers within an AutoCAD drawing. The most common are entity layers and layer stacks. Entity layers contain entities, and layer stacks consist of multiple entity layers. Object layers are not usually created directly in AutoCAD. Object layers are usually found in architectural drawings, and they are not part of the model.

An AutoCAD drawing is not really a separate drawing file. Rather, it is a snapshot of the model at a particular time. The model is updated each time the user makes a change. However, changes made to a drawing are not usually saved until the user exits the drawing. This is called blocking and prevents the user from accidentally saving changes.

By default, users can only edit objects that are on the same layer as the active view. If they edit an object that is in a different layer, the only way to change that object is to exit the drawing and reload the drawing. This is called snapping and is usually disabled by default.

By default, the cursor is in a hidden mode. This allows the user to move the cursor and select objects with the keyboard

since AutoCAD 2012, the program’s user interface has incorporated ribbon interface.

AutoCAD support non-registered users
AutoCAD 2013 Release 14 brought a number of additional features and enhancements to AutoCAD. Access to private information about objects that are hidden on the drawing canvas was one of the main features. This is an important feature for non-registered users.

Version history



AutoCAD can be configured to support Unicode characters in its interface.

Until the release of AutoCAD 2014, there was no guarantee that Unicode strings could be entered into the drawing. If the user tried to enter a string containing a character not supported by the Windows system, the program would crash. However, AutoCAD 2014 is able to import Unicode text strings in raster formats such as PNG and TIFF.

Screen readers

AutoCAD has had screen reader support since the release of AutoCAD 2004. When a drawing is opened in AutoCAD, the screen reader announces a number of menus and features available in the software. The screen reader can be activated from the application menu, the window menu and the ribbon. Screen readers support multiple language support.

AutoCAD can also display drawings as PDF files, which include HTML-based formatting and hyperlinks.

AutoCAD Map 3D

The AutoCAD Map 3D is a feature-rich AutoCAD version for geospatial and map data. It was designed to allow a user to create maps in the same manner as AutoCAD. The product was designed to be fast and simple to use. It allows users to easily import and export map data as shapefiles.

AutoCAD Map 3D was designed to reduce the level of programming required to produce maps with AutoCAD. A number of basic features are provided by the Map 3D product, including map projection, map templates and the ability to export map data in common file formats. The product also supports various mapping tools, including the ability to draw geometric shapes and save map-based files.

AutoCAD Map 3D is one of a number of applications that enable an AutoCAD user to create shapefiles, while incorporating the advantages of the AutoCAD map environment. It is a solid object-oriented development tool. The product supports multiple languages and character sets.

The product supports a number of

AutoCAD 2022 [New]

AutoCAD Interoperability was a project that aimed to convert 3D objects from one AutoCAD software to another. This is no longer supported by AutoCAD.

Importing Multipart Objects and Advanced Multipart Importing

With AutoCAD LT 2023, you can connect Revit models to your AutoCAD drawing for real-time collaboration. First, you can import geometry from external sources into a Revit model. And second, you can import geometries from a Revit file directly into AutoCAD.

Creating a Picture Library:

You can create a Picture Library to store images in an efficient way, and then bring them into drawings for reference or even reusing them across multiple drawings. (video: 2:06 min.)

New Layouts and Mass-properties:

You can define layouts to control the way layout drawings appear in your drawing. (video: 2:36 min.)

New Features in the Solid Editing (SEL) View

Create a new 2D or 3D drawing for editing 3D solids. (video: 2:52 min.)

Smart Snapping:

You can align the active entity in your drawing. Now, you can move and rotate entities without breaking the alignment. (video: 1:15 min.)

Advanced Multipart Importing

Import your Revit models into AutoCAD directly. With a Revit-based model, you can now use the Autodesk Exchange Protocol (AXP) to bring it into AutoCAD, ready for editing or further manipulation. (video: 4:10 min.)


You can now copy and paste regions, 3D solids, and views from one drawing to another. And if you’re using the AEC (architecture, engineering, and construction) or MEP (mechanical, electrical, and plumbing) software, you can use the copy/paste functionality to quickly transfer any drawing you’ve created from the Revit platform into your AutoCAD projects. (video: 5:02 min.)

Performance Improvements:

You can now open and work with more files at the same time. If your drawing is large or complex, you can open even more files to edit at the same time.

Expanded View Management:

View options for multiple views in
