AutoCAD is a commercial computer-aided design (CAD) and drafting software application. Developed and marketed by Autodesk, AutoCAD was first released in December 1982 as a desktop app running on microcomputers with internal graphics controllers. Before AutoCAD was introduced, most commercial CAD programs ran on mainframe computers or minicomputers, with each CAD operator (user) working at a separate graphics terminal. AutoCAD is also available as mobile and web apps.
AutoCAD is used in industry, by architects, project managers, engineers, graphic designers, city planners and other professionals. It was supported by 750 training centers worldwide in 1994.
Dronfield is a town in North East Derbyshire, England, which includes Dronfield Woodhouse and Coal Aston. It lies in the valley of the River Drone between Chesterfield and Sheffield. The Peak District National Park is three miles (4.8 km) to the west. The name means open land infested with drones (male bees).
The town existed before the 1086 Domesday Book, and has a 13th-century parish church. In 1662, Charles II granted the town a market, although this later ceased. The industrial history of the town includes coal mining, the wool trade, the production of soap and steel, and engineering. Today a range of manufacturing firms still operate in the town.
Dronfield's population increased dramatically in the post-war years from 6,500 in 1945 to its current size of just over 21,000.
The football ground to the north of the town is currently the home of Sheffield F.C., the world's oldest football club.
