Abstract

A system for changing the display characteristics of a drawing has one model style, a top graphics table memory for storing a top graphics table, a chart table memory for storing a chart table, a default box graphics table memory for storing a default box graphics table, and a level table memory for storing level tables, display routines for displaying the drawing on a display device, and model routines for changing the model style of a drawing. The model routines, when changing the model style, retrieve a model style from a model style library. The model routines re-configure the chart table, the default box graphics table, and the level tables according to the retrieved model style. The system includes a set of filters that control the application of a model style. As the model routines re-configure the chart table, the default box graphics table, and the level tables, the model routines analyze the filters. The model routines do not modify certain selected visual characteristics of a drawing if the filters are set. Finally, the model routines and display routines re-configure the top graphics table for the display of the drawing.
