Description: TCW is the standard drawing file format for TurboCAD. TCW stands for TurboCAD for Windows. The format was first used with the introduction of the Windows version of TurboCAD in 1993.

History: TurboCAD was created by Stephen "Yogi" Russell in South Africa in 1986 under the name InterCAD. It was created to be a low-cost alternative to AutoCAD. In late 1986, the software was released in the United Kingdom with the TurboCAD name. Milan Systems of America also began selling TurboCAD in the United States in late 1986. To increase interest in the product, Milan Systems began selling TurboCAD bundled with mice from IMSI (International Microcomputer Software, Inc). IMSI licensed the source code from the original developers and released its own improved version in 1990. In 1993, versions of TurboCAD for Mac and Windows were released. Starting with version 4 in 1995, TurboCAD began introducing 3D support, which helped to make the software very successful. Over the next versions, the 3D abilities were greatly increased. In June 2006, IMSI, which had changed its name to Broadcaster, Inc., sold TurboCAD to IMSI/Design, LLC.

  • Adoption:

As noted in the history, the TurboCAD software and the accompanying formats were sold several times. TurboCAD was originally developed by Stephen "Yogi" Russell. It was then further developed by Pink Software. Milan Systems began selling the software in the US, but did not develop it. IMSI licensed TurboCAD from Pink Software in 1990. IMSI changed its name to Broadcaster, Inc. In 2006, IMSI/Design, LLC was formed to develop and sell TurboCAD and purchased the software from Broadcaster, Inc.
