Practical Problems in Mechanical Drawing and Blue-Print Reading (Classic Reprint)

Excerpt from Practical Problems in Mechanical Drawing and Blue-Print Reading Much criticism has been directed at the copy method of teaching Mechanical Drawing and undoubtedly some pupils have copied drawings which they did not clearly understand. The attempt, however, to make a problem of every drawing has been' responsible for much poor teaching. Many boys have gained the impression that a third view was always necessary, when as a matter of fact, two views of an object gave all of the information necessary and the drawing of the third view was.a waste of time. Similarly if dotted lines on a view give the pupil a clear idea of an object, the drawing 'of a section is poor practice. It is suggested that the test drawing, the side view or section or sketch be made on a sep arate sheet in pencil, thus saving time and avoiding the possibility of the pupils receiving the impression that it must be made to complete the drawing.
