摘要

Macroinstructions for computer-aided design systems can be designed by the user without special language or syntax using the systems' menu-driven instruction set. Macroinstructions can be nested. The designer constructs patterns and the steps are recorded. Parameters can be selectively included in the macroinstructions or can be supplied at the time the macroinstructions is played. The designer can also create geometrics by storing a routine that will automatically draw dependent figures by supplying the dependent parameters to maintain given relationships between the dependent and independent figures according to the parameters supplied for the independent figure.
