AutoCAD was developed initially as a B-Series desktop application for the DOS operating system (OS). Subsequently, the B-Series was expanded to include an A-Series, a version of AutoCAD suitable for the Apple Macintosh. Today, all versions of AutoCAD are designed for use on Microsoft Windows-based operating systems.

The predecessor of AutoCAD was first released in 1968 as a low-cost version of the CAD/Drafting System (CADDS) program developed by the U.S. Navy. AutoCAD is one of the most significant and long-lived software products in the history of the personal computer. The original AutoCAD (ACAD) 1.0 product ran on a single PDP-11 CPU (or later, an Intel 8080 CPU), with a text-only mode and a graphics mode that ran on either the built-in MDA or an external EGA graphics card. Later, a 16-bit version of AutoCAD (known as AutoCAD 16) was released, which ran on a 16-bit Intel 80286 processor. By the mid-1980s, AutoCAD was the most widely used CAD program in the United States. During this period, the product underwent significant changes, adding features such as multicolor graphics, the ability to edit three-dimensional drawings, and a new user interface (UI) that is very similar to the one found in today’s AutoCAD versions.

The first releases of AutoCAD for the Apple Macintosh were in 1982 (version 1.0), 1983 (1.1), and 1985 (1.4). Apple’s MacPaint software was originally developed as a competitor to AutoCAD. After several years of beta testing, AutoCAD was released on January 30, 1987 as version 1.5 (at a price of US$1,995). In addition to standard 32-bit color graphics, this version also supported 256-color graphics. In June 1990, AutoCAD 1.5 was extended to support Windows 3.1 (Windows 3.1 is an operating system developed by Microsoft, and it was the first 32-bit operating system that ran on a

Autodesk Project Construction (formerly Autodesk Project Builder) is a program used to create project information and to link it to a construction schedule for a building. It can be used for a single project or as a construction information management system (CIMS).

With the release of AutoCAD Product Key 2017, Autodesk added a Windows Forms designer, which has become the primary design tool for the new version of AutoCAD Crack For Windows.

Autodesk Fusion 360 is an online tool that facilitates the integration of functional and visual aspects of the design into a single 3D package.

With the release of AutoCAD 2018, Autodesk added the ability to capture the flow of a design from a plan through a program that can be used to create 3D models.


AutoCAD is primarily used in the following fields:

Architects use AutoCAD for design of both drawings and schedules.

Civil Engineering
Engineers and surveyors use AutoCAD to create cross sections, and for management of civil engineering data and software.

Data Visualization and GIS
Geographic information systems (GIS) professionals use AutoCAD and other software packages such as SketchUp and Trimble Raster to create and display 3D data on maps.

Municipal Engineering
Municipal engineering professionals use AutoCAD and other software packages, including MicroStation, to create detailed plans and drawings.

The Visual Basic for Applications (VBA) programming language in Microsoft Office is an additional tool that many AutoCAD users use for a variety of tasks.

Visual LISP
Visual LISP (VLP) is a programming language that is very similar to BASIC and Pascal. Visual LISP was designed for developers who create plug-ins for AutoCAD.

Some colleges use AutoCAD as part of their AIA-PEDS accredited education programs, or they use it as a teaching tool.

Although the majority of AutoCAD’s market is in Windows, one of its main competitors is FreeCAD, a free and open-source CAD software for Linux-based operating systems.

Category:Point-of-saleA radio frequency (RF) communication system includes an uplink and a downlink to facilitate communication of data between one or more mobile stations and one or more base stations. For the purposes of this disclosure, the terms “mobile station” and “mobile terminal” are used interchangeably to refer to a communication device that can operate in a wireless communication system. The terms “base station” and “access point” are used interchangeably to refer to a transceiver station that communicates with one or more mobile stations. The term “base station” may also refer to a different communication device that functions similarly to the base station, i.e., a device that transmits and receives communications.
In some systems, a mobile station and a base station can transmit and receive information using Orthogonal Frequency Division Multiplexing (OFDM). In particular, OFDM works well for high data rate transmissions. The U.S. Institute of Electrical and Electronics Engineers (IEEE) 802.11a standard for wireless local area networks (WLANs) has adopted OFDM as the transmission technology. The IEEE 802.11a standard is often referred to as WiFi. It is envisioned that mobile stations can operate in such a system and use OFDM to communicate with the base station. For example, the IEEE 802.11a standard supports data rates up to 54 Mbps (megabits per second) for the 5 GHz band and up to 11 Mbps for the 2.4 GHz band. For each carrier in the OFDM system, the carrier can use either Quadrature Phase Shift Keying (QPSK) or Quadrature Amplitude Modulation (QAM) to transmit data.
FIG. 1 is a graph illustrating a conventional data frame 10 that is used to transmit information. The data frame 10 comprises two data blocks, a short preamble 12 and a data block 14. The preamble 12 is used to synchronize the receiver and is typically relatively short in duration. The data block 14 is typically much longer than the preamble 12.
In conventional OFDM systems, a receiving device can receive the data block 14 and then process the data to obtain the transmitted information. For example, the receiving device can perform channel estimation and equalization to generate a received signal that approximates the transmitted signal. The receiving device can then perform demodulation

What’s New In?

Create actionable feedback with Markup Assist. View the “Markup Assistant Tips” video to learn how to incorporate markup instructions that are automatically added to a drawing.

The auto-add feature will work for feedback marked up in Illustrator or other vector-based software and not for feedback added in printed paper and PDFs. To incorporate feedback from those files, open the Import/Share dialog and choose Markup Assist from the “Import from” drop-down.
