AutoCAD is a registered trademark of Autodesk, Inc.

Autodesk introduced AutoCAD in 1982 as a desktop CAD program for computers with graphics display systems. Before the introduction of AutoCAD, most CAD programs ran on mainframe computers or minicomputers, with each CAD operator (user) working at a separate graphics terminal.

In the late 1980s, Autodesk began to develop a “convergent design environment,” which was expected to eliminate a number of technical hurdles that had plagued the design process by providing an integrated CAD environment. In 1989, the first incremental version of AutoCAD was introduced as a stand-alone graphics system that could run on personal computers (PCs). The following year, Autodesk released AutoCAD LT as a free desktop CAD program, and added engineering visualization and simulation capabilities.

In October 1991, Autodesk released AutoCAD version 3.0, which added parametric modeling, rendering, animation, and several other features. AutoCAD 3.0 was the first version of AutoCAD that was compatible with Windows 3.0, Microsoft DOS, and MS-DOS. In September 1992, Autodesk released AutoCAD 3.5, which added the ability to construct and construct solids and surfaces in stereo and polygonal modeling environments.

In November 1993, Autodesk released AutoCAD version 4.0, which introduced a new user interface and many enhancements to the software’s parametric and surface modeling features. AutoCAD 4.0 was the first version of AutoCAD that supported Windows 3.1. This release also introduced an “AutoCAD Add-In” option for users who were not comfortable with programming, as well as the ability to save and load data in formats other than the default CAD formats.

In June 1994, Autodesk introduced AutoCAD version 5.0, which introduced the AutoCAD component architecture, a feature that introduced intelligent, distributed, and flexible data structures. AutoCAD 5.0 also introduced a new user interface and the ability to save and load data in the AIM (ASCII Image Manipulation) file format, which allowed it to work with software programs that didn’t natively support CAD data formats.

In February 1995, Autodesk introduced AutoCAD version 6.0, which introduced a new floating window option and additional advanced graphics capabilities. AutoC

The Digital Drafting and Design (DDD) Suite is an Integrated development environment (IDE) designed to assist the Autodesk product designers with their design and drafting processes. There are seven editions of DDD: DDD Core, DDD Elements, DDD Allure, DDD Core Architect, DDD Entertainment, DDD Material Designer and DDD Entertainment.

Other features of AutoCAD include the ability to have multiple Autodesk Product Line Identifiers (PLIs). The ADM-E license of AutoCAD allows multiple PLIs.

As of 2014, AutoCAD allows users to import their drawings into the cloud.

AutoCAD includes the ability to use AutoCAD maps and align them with maps and alignments within a drawing and external data. There is also the ability to import and export DWG, DXF, PDF, and JPG files to be saved on cloud services and web applications.

There is an option to reduce the bandwidth of large files and enable the use of Dropbox for file sharing.

AutoCAD 2013 and later allows for the ability to create documents and features on the web.


AutoCAD LT (Linear Technology) is a free, open-source AutoCAD clone. AutoCAD LT has been the most popular CAD program because it is based on the open source Java programming language. One of the largest implementations of AutoCAD LT is found in the KiCAD project, a free, open-source electronic design automation (EDA) system, and examples of other EDA tools using AutoCAD LT can be found at the EDA4D project.

AutoCAD LT is used in many industries that are not involved in electronics. The hardware design industry also uses AutoCAD LT for model-based process design.

AutoCAD LT versions: 1.5, 2.5, 3.5, 4.5, 5.5, 6.5, 7.0, and 8.5 are available as free downloads and runs on most operating systems.

In addition to the native ability to read DWG files, AutoCAD LT also supports the following drawing formats:

AutoCAD LT supports several native features that are not available in other AutoCAD products, such as “raster to raster” (layer-to-layer) editing and the ability to load, edit and save layer-based drawings in a format

La Tijera Boulevard is a arterial road connecting the city of Miami to the communities of southwest Miami-Dade County, Florida. It was named for El Tijeras Creek, and is the main thoroughfare for several communities including Hialeah, South Miami, and West Hialeah.

Route description
La Tijera Boulevard begins at NE 78th Avenue and US 1 in Miami. It heads east and then north through the communities of Southwest Miami-Dade County. It meets the termini of CA 99 (Krome Avenue), CA 74 (SW 119th Street), SR 905 (US 27), and Florida’s Turnpike at the Hialeah-Miami Exposition Interchange.

On November 12, 2016, a flash flood hit the city of Hialeah, causing catastrophic damage and leaving the roadway under water for hours. Several businesses and the Howard M. Michael Recreational Center were destroyed, which closed for reconstruction.

What’s New in the?

Drafting tools:

Select parts of your drawing for drafting, with improved accuracy and precision.

3D Architecture:

Revisit and adapt your 3D models with new design tools for 3D architectural modeling.

AutoCAD Architecture:

Architectural design tools for AutoCAD, including 3D modeling, design history, and versioning.

User-friendly User Interface:

Cleaner and more consistent interface. Cleaner UI to improve your workflow, and keep you from wasting time on getting lost.

AutoCAD Architecture 2023 is coming with a few highlights and few features that are going to make architectural design even easier than before, and will create an architecture-ready work environment for you!

Architectural Sketch:

Improve your design workflow with 2D sketching. Sketch your design in 2D at the same time you are working in 3D. Sketch over your model and switch between 2D and 3D to get the most from your design.

Architectural Design History:

Revisit and adapt your design with design history and versioning, which lets you compare a design from one version to another.

Extended 3D Part Library:

Get a set of parts built for your drawings, so you can build on top of your designs.

3D Modeling:

Get your drawing on paper and create a 3D model. These 3D models are suitable for architectural design.

Video Tutorials:

Learn how to use the new and improved architectural design tools.

Architectural Sketch and User Interface:

Architectural Sketch: The new AutoCAD Architecture 2023 software gives you a 2D sketching tool that can be used for your architectural designs.

An architect’s 2D sketch is another way of looking at a drawing. With AutoCAD Architecture 2023, you can add 2D sketch elements to your architectural models. These can be used to create conceptual drawings, show the design intent of your building, or communicate with others.

2D sketching gives you the power to add more to your drawings. Imagine how helpful it will be for your design team to review your sketches before the drawing starts. You can easily turn your 2D sketch into an AutoCAD drawing, and then do a 3D model of it.
