Shape Data Limited

Shape Data Limited is a computer software company in Cambridge, England that specializes in developing programs for engineering and manufacturing professionals.^[4]

Overview

Established in 1974 by several doctoral students of the University of Cambridge Computer Laboratory, the company was a pioneer in computer graphics with early industry advances in solid modeling design and boundary representation. The company revolutionized the computer aided design (CAD) industry in the 1970s and 1980s, by creating and commercializing the solid modeling software market in 1978.^[1][2][5] The use of solid modeling techniques allows for the automation of several difficult engineering calculations that are carried out as a part of Shape Data's software programs, including simulation, planning, and verification of design processes of three dimensional objects. Shape Data released a series of products that helped create the foundations of computer aided design programming, namely Romulus, Romulus-D, Parasolid, and the Unigraphics Solids programs.^[5] The Parasolid program remains an industry standard for engineering departments and companies, in the design of manufacturing products from small scale tools and equipment to automobiles and airplanes.

Shape Data was sold several times to large multinational companies in the information technology industry. At present, the company is a subsidiary of Siemens AG.^[6]

History

University of Cambridge

Shape Data was founded in 1974 by Doctors Charles Lang, Ian Braid, Alan Grayer, and Peter Veenman.^[2][7] Veenman became the sole employee of the company at the time of its founding, while Lang, Braid, and Grayer initially continued work at the University of Cambridge Computer Laboratory. All four founders were doctoral students at the University of Cambridge. In 1965, Professor Maurice Wilkes and his graduate student Lang established the Computer Aided Design Group at the University of Cambridge Computer Laboratory.^[2] The initial purpose of the research group was to develop tools for building mechanical CAD/CAM systems.^[2] In particular, the group worked to engineer early forms of computational geometry, computer graphics, and software system components.^[2]

Early revenue for Shape Data came from business-to-business consultancies.^[8] In 1975, the company was contracted by the General Electric Company to develop a solid modeler based on the computational geometric work of Ian Braid's Ph.D thesis.^[8] In 1978, after three years of development, Shape Data released Romulus, the world's first commercialized solid geometric modeler software program.^[9][10]

By 1980, the company had expanded to about a dozen employees.^[8] The company was the target of a takeover bid by Weir Group, followed a year later by another takeover bid by Racal-Redac.^[8] In 1979, Shape Data reached an agreement with Evans and Sutherland of Salt Lake City, Utah to distribute Romulus in the United States.^[8] Evans and Sutherland President Dave Evans became interested in acquiring Shape Data, as the young company was seen as an entry point into advanced computer aided engineering. Concurrently, the company founders saw Evans and Sutherland as more favorable to the strategic development goals of their company and an opportunity to inject needed capital into Shape Data for further research and development of Romulus.^[8]

Evans & Sutherland

In 1980, Evans & Sutherland Computer Corporation entered into a contract with Shape Data to market the Romulus geometric modeling program.^[11] The company was sold to Evans & Sutherland in 1981. After acquisition, Evans & Sutherland injected a large amount of capital into Shape Data, allowing for rapid expansion of staff and procurement of computing equipment. In 1981, Shape Data had 17 employees. In 1983, the company had 40 and by 1986 staff had grown to 70.

In May 1984, the managing director position was created and Peter Veenman was appointed.^[8]

In 1988, Shape Data was close to fragmenting.^[8] In January 1988, Siemens bought Shape Data's Parasolid product and development group from the parent company. The administrative staff and the Romulus-D product and development group were left out of the deal. In 1988, Caterpillar committed to the Romulus-D program as the first major customer. Caterpillar discovered shortly thereafter that Parasolid, the operating system modeler to Romulus-D, was being sold to the German conglomerate. Caterpillar hastily arranged the takeover of financing of Shape Data's to prevent the sale of Parasolid to Siemens.

McDonnell Douglas

Shape Data was sold to McDonnell Douglas Information Systems Limited on October 31, 1988.^[12][13] Ron Belcher, a senior software project manager at McDonnell Douglas, was appointed head of Shape Data at the time of the acquisition.^[13][8]

Belcher created a paradigm shift in the management of the company. Since the founding of Shape Data, the culture focused on technology-led development and managerial decision making. Under Belcher, the central focus of the company shifted into financial and market oriented strategic management decision making.

The company pursued a blue ocean strategy by being the first company to create and enter the three dimensional CAD market. In 1988, Shape Data developed Parasolid, an upgrade of Romulus, that allowed the joining of boundary represented surfaces together as a solid. This program was the most advanced solid modeling kernel available on the market at the time of its 1989 release.^[14]

EDS

In 1991, the McDonnell Douglas Systems Integration groups, including Shape Data, were acquired by EDS (then a part of General Motors Corp., now part of HP Enterprise Services). EDS branded the acquired business as EDS Unigraphics. Eventually, in 1997 EDS set up its Unigraphics division as a wholly owned subsidiary called Unigraphics Solutions.^[15]

Siemens

Shape Data was sold to Siemens AG on January 24, 2007.^[16][17][18] The company is presently a subsidiary of Siemens PLM Software, a business unit of Siemens AG.

Products

Romulus

The Romulus program was introduced in 1978 after three years of development.^[2] It is the first commercially licensed geometric modeling kernel in the world.

Parasolid

Parasolid, alongside ACIS, is the current industry standard for three-dimensional solid modeling kernel software. Shape Data first began developing Parasolid in 1985.
