Abstract

A method for generating a parametric design on a computer without the use of a programming language. A drawing processor is used to create a master drawing from which other drawings of different dimensions can then be synthesized by modification of the master drawing. Instead of each dimension in the master drawing being given a fixed value, it is given a label. These labels are replaced at run time by dimensions the user provides or dimensions which are calculated as described in a design plan. When the program is run, the system uses simple language to prompt the user for each design value. It incorporates the response with data previously entered into the design plan. If a response is unclear, a request is made for clarification. As a draftsman would do, the invention merges the design values with data from both the design plan and the master drawing to create a finished drawing. in executing a parametric design, the user selects the controlling design plan to be used as a basis of the design. Acting on information contained therein, other design plans may be loaded and executed automatically. As a result, images of associated master drawings are modified and/or combined to represent the design. The final design is represented by electronically stored data which can be utilized to create a visual display such as a drawing and/or directly to manufacture a part, structure, etc. As an option, the user's direct role in the process can be supplanted by a computer program.
