History of AutoCAD
An early history of AutoCAD is detailed by the CAD Software Revolution (Arcane Research) author Jon A. Heron in the book and on his website.
AutoCAD – the first, true CAD
In the early 1980s, architect and programmer Darryl Borg was searching for a tool to build drawings for a wind tunnel used at the Environmental Wind Tunnel (ETWA) at the University of Minnesota. He quickly discovered the EDR 2 wind tunnel drawing program offered by Environmental Dynamics Research, Inc., the owner of the ETWA. The program was very cumbersome. Fortunately, Darryl was also exploring the possibility of a computer to draw and store designs and found that there was no readily available, practical, integrated CAD package. This was the challenge he took on, eventually building his first CAD product called AutoCAD. (The first computer-aided design package available on the market for the PDP-8 microcomputer was Novation’s Advanced Design Suite, written by Chris Russel and John Rodgers.)
AutoCAD, first released in December 1982, was the first true CAD package. It was a desktop application running on microcomputers with internal graphics controllers. Before AutoCAD, most commercial CAD packages ran on mainframe computers or minicomputers, with each CAD operator (user) working at a separate graphics terminal.
AutoCAD debuted in the spring of 1982 as a drafting program and was originally sold for the Xerox 9600 series of minicomputers. This first product, developed by Darryl Borg, was released as a subscription-based version. In late 1982, the cost of the application was increased to $3,700, and in the summer of 1983, the first commercial version of AutoCAD was released.
In September 1983, the United States Postal Service (USPS) ordered a half million copies of the program to produce post office building blueprints. At the time, the U.S. Postal Service was concerned that the cost of conventional CAD was prohibitive for creating post office building blueprints and that the USPS would experience a decline in service efficiency and a reduction in the number of blueprints produced when conventional CAD packages were introduced. AutoCAD was created to meet these objectives.
AutoCAD 1
In 1983, the first version of AutoCAD was released. It was called AutoCAD 1.0 and was developed for the Xerox 9600 computer with
AutoCAD Crack Patch With Serial Key
AutoCAD 2022 Crack can read DWG and DXF files. The AutoCAD Serial Key feature Data Exchange is a complement to the Exchange file format, which permits the exchange of CAD data between different programs. By using the Data Exchange feature of AutoCAD, a user can save or import data.
AutoCAD’s drawing engine is based on the object-oriented programming language, ObjectARX. It is able to edit and manipulate objects using object-oriented programming techniques.

1. Field of the Invention
The present invention relates to the field of sewer collection piping systems in general, and in particular to a sewer collection piping system that is suitable for a pre-piped sewer collection system.
2. Description of Related Art
Sewer systems are in use in many residential and commercial buildings. Many residential buildings are constructed with pre-piped sewer systems. Pre-piped sewer systems typically consist of manholes at the juncture between the street and the building. The manholes allow access to the sewer system for collection piping. The sewer collection piping is laid out in a convenient route for access by the plumber to carry out repairs and the like.
The sewer collection piping is typically laid out in a square or a rectangular grid, depending on the location of the manholes and/or the piping configuration. The grid is generally laid out in a grid pattern, with the x-axis being
