This text introduces basic drafting concepts and applies them to specific architectural, engineering, and construction (AEC) problems. No prior knowledge of drafting is required. The Criterion Reference Instructional (CRI) format is used to teach drafting by presenting information and immediately reinforcing skills with practice exercises. The text focuses on gaining a solid understanding of all basic drafting techniques found in the construction industry for both residential and commercial structures, not on materials used. An overview of construction industry drafting is presented in Chapters 1-3 providing insight into this area of professional work. CAD applications are provided where appropriate.
