Mechanical Drafting

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. The above principles were followed by first design ing a very flexible course in drafting, substituting draw ings of machine parts for the conventional geometrical figures. The work was arranged into definite groups, according to subject, each group being scheduled for a definite amount of time. Second, the text was so ar ranged that section, lesson or chapter one, gave all information necessary for the work included in group one, etc.
