Book Description
This book makes possible the accurate geometrical solution of all
problems of pattern development normally encountered, by giving
examples arranged according to a systematic plan which
progressively illustrates the underlying principles. In the five
“courses” into which the book is divided, the three basic
methods of Radial Line, Parallel Line and Triangulation are
applied in more and more complex examples, culminating in the
solution of difficult problems of pipe intersection, twisted
surfaces and spiral chutes. Each stage in the solution of the
problem is clearly explained and shown in detailed drawings, and
the superiority of the accurate geometrical method, in terms of
time and material saved, is effectively demonstrated. All sheet
metal workers will find this book invaluable.
