Verfahren zur Erzeugung von graphischen Modellen und rechnergestütztes Entwurfssystem.

摘要

A computer aided design system generates graphical models of 2- or 3-dimensional objects with at least partially variable dimensions, in particular mechanical parts. In order to generate models having a predetermined plurality of structural elements, like through-holes, etc. being distributed over the model in a predetermined manner, the computer aided design system is provided with means for selecting a sub-group of design commands corresponding to a structural element of the model. After inputting of a replication command, the selected element is replicated in a predetermined manner, e.g. distributed either by rotation about a predetermined center point at predetermined angular steps or shifted along linear axes with predetermined spacings or scaled at predetermined locations.
