AutoCAD and Its Applications—Basics
processes to be automatic or to happen immediately, but if you hurry and do little or no
planning, you may become frustrated and waste time while drawing. Take as much time
as needed to develop drawing and project goals so that you can proceed with confidence.fi
During your early stages of AutoCAD training, consider creating a planning
sheet, especially for your first few assignments. A planning sheet should document fi
the drawing session and all aspects of a drawing. A freehand sketch of the drawing
is also a valuable element of the planning process. The drawing plan and sketch help
you establish:
• Drawing layout: area, number of views, and required free space
• Drawing settings: units, drawing aids, layers, and styles
• How and when to perform specific tasks fi
• What objects and symbols to draw
• The best use of AutoCAD and equipment
• An even workload

Drawing Standards
Most industries, schools, and companies establish standards. Drawing standards
apply to most settings and procedures, including:
• File storage, naming, and backup
• Drawing template, or template, files fi
• Units of measurement
• Layout characteristics
• Borders and title blocks
• Symbols
• Layers
• Text, dimension, multileader, and table styles
• Plot styles and plotting
Company or school drawing standards should follow appropriate national
industry standards whenever possible. Although standards vary in content, the most
important aspect is that standards exist and are understood and used by all CADD
personnel. When you follow drawing standards, your drawings are consistent, you
become more productive, and the classroom or office functions more efficiently.fi fi
This textbook presents mechanical drafting standards developed by the American
Society of Mechanical Engineers (ASME) and accredited by the American National
Standards Institute (ANSI). This textbook also references International Standards
Organization (ISO) mechanical drafting standards and discipline-specific standards fi
when appropriate, including the United States National CAD Standard (NCS) and
American Welding Society (AWS) standards.
