Synopsis

Excerpt from Blueprint Reading: A Practical Manual of Instruction in Blueprint Reading Through the Analysis of Typical Plates With Reference to Mechanical Drawing Conventions and Methods, the Laws of Projection, Etc

Reading Blueprints. T 0 be able to read a blueprint is as essential to'' a workman''s success as to be able to read printed mat W ter. To read blueprints readily, he must know some of the prin ciples of making drawings. These are explained to a considerable length and with close attention to detail in Mechanical Drawing, Parts I, II, and til-and these books Should be read mostcare fully. This is somewhat equivalent. To learning the alphabet in learning to read printed text. The workman should first under stand that a blueprint is a record of instructions given him to read. Second, he should realize that the language used by the draftsman In making his drawing IS largely a language Of lines and that, unless he knows how to read lines, the instructions recorded on the blueprint are essentially in a foreign language. (read care fully and memorize page 41, Mechanical Drawing, Part II.) To read a blueprint, the-first thing''is to study the several views until one has a_good mental picture of what he is to construct. AS the blueprint is a flat surface, it is necessary for the workman to use his imagination to ''make the lines and views lift up from the paper. When a clear-cut mental picture has been formed, the dimensions Should be studied until understood. N ext all the let tered text should be read and considered. Carelessness in any one of these three''respects is not tobe Nexcused.
