1. In a method for displaying drawings which consists of intersecting line segment representations, a method for converting input data defining one-dimensional line segment representations having length but no width into data defining two-dimensional representations having length and width, comprising the steps of:

  • generating definitions of pairs of lines parallel to the lines defined by the input data;

    identifying points of intersection of the lines defined by said generated definitions; and

    combining the identified points of intersection with the generated definitions to establish the end points of said pairs of lines, said pairs of lines comprising the two-dimensional representations.
