摘要

SIMPLIFIED CAD PARAMETRIC MARCOINSTRUCTION CAPABILITYINCLUDING VARIATIONAL GEOMETRICS FEATUREAbstractMacroinstructions for computer-aided design systems canbe designed by the user without special language or syntaxusing the systems' menu- driven instruction set.Macroinstructions can be nested. The designer constructspatterns and the steps are recorded. parameters can beselectively included in the macroinstructions or can besupplied at the time the macroinstructions is played. Thedesigner can also create geometrics by storing a routinethat will automatically draw dependent figures bysupplying the dependent parameters to maintain givenrelationships between the dependent and independentfigures according to the parameters supplied for theindependent figure.809-88-012
