Abstract: An adaptive CAD system, comprising: (a) gathering data consisting of at least one of (i) human generated information and techniques, and (ii) machine generated information and rules; (b) processing the gathered data by instructions to produce processed knowledge containing script without a product or part design; (c) recursively editing the processed knowledge to continuously improve the script to form an executable part design, such processing being carried out by inputting into the editing process at least one of (i) recently learned data, (ii) associative techniques, relations and features, and (iii) knowledge-based rules and instructions and (d) inputting the history of step (c) into processed knowledge, such inputting creating captured improvement criteria, that is iteratively and recursively feeding back into either the recursive editing process or into processing of step (b) to effect evolvement of an executable design form.
