This volume is an excellent practical overview of drafting–the language of engineering. Designed to be used by students without any outside instruction, every lesson can be accomplished by hand with common drafting tools (such as a t-square, triangle, mechanical pencil, etc.). Lessons can also be repeated on the computer using a CAD program (download for free from the internet or purchase). Lessons will expose the student to many types of drafting and standards. Info includes how to use drafting tools, letter, create geometric shapes, sketch models, surface texture, perspective, and much more. Spiral bound, 136 pages, for ages 14 and up.
