Book Description
Excerpt from The Essentials of Descriptive Geometry IT has been the endeavor Of the author in writing this text to include only those portions Of descriptive geometry which possess industrial utility and which develop the qualities Of mind so essential in a draftsman. First and foremost descriptive geometry should aim to teach projection. A draftsman must be able both to read and to write drawings with facility, and projection is the very grammar Of the language Of the designer. Secondly, descriptive geometry should aim to develop the ability to solve problems concerning the relations Of points, lines, and planes. These are, of course, but elementary parts Of all engineering structures as shown on drawings and it is important that a draftsman be prepared to solve problems relating to them directly on the drawing board. Thirdly, and perhaps most important Of all, descriptive geometry should aim to promote the ability to analyse a problem into its component parts, to reason from a given set Of conditions to a required set Of conclusions, and to build up from the drawing a mental picture of the Object which is there represented, for Without the ability to analyse, to reason, and to Visualize a draftsman is lacking in the essential qualifications of his calling.

Book Description
Excerpt from Essentials of Descriptive Geometry It may help some instructors who contemplate using the fol lowing text-book to know how the authors have used the book in their classes. With this in View, the following general method for conducting the course is suggested and an outline of lessons given. Each instructor will, no doubt, need to alter the outline to some extent to suit the conditions under which he works. At the University of Wisconsin, descriptive geometry is given as a three credit course for one semester of eighteen weeks. Each week's work consists of one general lecture for all students in the course, one recitation, and two two-hour drafting periods for each section. One of the two-hour draft ing periods is sometimes turned into a one-hour recitation period. At the lecture, the general principles involved in the next lesson are explained, general announcements made, and prob lems assigned for a home plate which is to be handed in at the beginning of the recitation period. At the recitation, the stu dents are drilled in the analyses of the problems and then sent to the black board with some particular problem to solve.
