A computer program for printing geometrically accurate structural fabric diagrams

Abstract Previously-published computer programs for printing structural fabric diagrams are discussed, and attention drawn to their statistical inaccuracy. The geometry of the problem is examined and a computer solution is described. A FORTRAN program to implement the latter is presented and discussed; it processes both linear and planar data and outputs a fabric-density diagram on a line-printer, using alphabetical characters to represent density levels. An option is included for printing beta-intersection density diagrams for planar data.
