Abstract : The GPRIME geometric language is a computer language for describing and manipulating a wide variety of geometric shapes. The GPRIME language processor is a computer program that translates the geometric language description into a set of consistent mathematical definitions using Bspline approximation techniques. GPRIME application programs are computer programs, such as finite element data generators, that make use of the mathematical definitions created by the language processor. This manual is intended for new and experienced users. It describes the GPRIME geometric language, the GPRIME language processor, and recommended procedures for geometric modeling with GPRIME. With the GPRIME language it is simple to create mathematical models of complex geometry. Classical shapes are defined using straightforward expressions, and more general curves and surfaces can be defined using digitized coordinate data. The GPRIME processor uses interactive computer graphics for defining geometry and for aiding in visualizing the model being created. The processor creates a geometric data base which may be used for restarting the definition process at later sessions. The GPRIME language was designed for use in creating finite element structural analysis models but can be applied wherever a description of geometry is required. This manual defines the form and syntax of the GPRIME language and its command structure.
