Master Syllabus DF1043, Dimensioning Procedures

Credits 3 Lab Hours 5 Lecture Hours 1 Clinical Hours 0

This course teaches the student the proper technique of dimensioning, the placement of dimensions, and the choice of dimensions. Dimensions are used to numerically or verbally describe the shape, size and character of the drawn product. Dimensions are given in linear distances, angles, or notes. The content of this course complies with ANSI/ASME standard Y-14.5M-1994.

For each unit of credit, a minimum of three hours per week with one of the hours for class and two hours for studying/preparation outside of class is expected.
