AUTOMATIC DRAWING SYSTEM

摘要

A technique for automatically producing drawings includes hand-drawing a group of similar images of a first type within an active area of a first sheet, scanning it with a scanner to produce corresponding runlength data, operating on the runlength data to form software objects representing the images of the first group, and storing the first software objects in a first software layer. A second group of images of a second type hand-drawn on a second sheet, which is scanned to produce corresponding runlength data which is then operated upon to form software objects representing the images of the second group and storing the second software objects in a second software layer. Data from the first and second software layers are operated upon to plot a first composite drawing including the images of both the first and second groups. Additional groups of similar images are drawn on additional sheets to obtain additional software layers and additional composite drawings. Global commands handwritten on sheets set system and sheet parameters. Editing directives are handwritten and hand-drawn within the active areas of additional sheets to modify and augment the previous software layers until a final, edited, complex composite drawing is obtained.
