How to Understand the Reading of Blue Print Drawings

Whilst the greatest effort has been made to ensure the quality of this text, due to the historical nature of this content, in some rare cases there may be minor issues with legibility. Throughout this book, I have used simple objects as illustrations upon which to base the instructions. Knowing that the weakness of many a writer of educational texts, lies in his failure to make known the things that are known to him as very simple, though in reality very hard to the reader, I have tried to men tion such simple facts in my explanation as would prove to be a stumbling block if not understood by the student. I have endeavored to make the subjects interesting and appealing, so as to leave no doubt in the reader's mind of every step that would lead to a complete grasp of reading a blue print drawing.
