Computer Aided Design - CAD 130

Geometric Dimensioning and Tolerance

3 Credit Hours
2 Lecture Hours
1 Laboratory Hours

Course Description

The student will learn to interpret blueprints with emphasis placed on Geometric Dimensioning and Tolerance. This course will introduce national and international geometric standards of form, profile, orientation, runout and location tolerances used in the manufacturing processes. Curriculum includes emphasis on print reading and measurements. This course can be used to prepare for the ASME GD&T Certification exam.


(A requirement that must be completed before taking this course.)

Course Competencies

Upon successful completion of the course, the student should be able to:

  • Interpret blueprints, including common drafting symbols.
  • Explore the scope of Geometric Dimensioning and Tolerancing (GD&T).
  • Perform mathematical operations with the use of a calculator.
  • Explain placement of Datums for manufacture and inspection.
  • Characterize Form Tolerances (Straightness, Flatness, Circularity, Cylindericity).
  • Characterize Orientation Tolerances (Parallelism, Perpendicularity, Angularity).
  • Investigate Location Tolerances (Positional, Concentricity, Symmetry).
  • Characterize Profile Tolerance (Profile of a Line, Profile of a Surface).
  • Characterize Runout Tolerance (Circular Runout, Total Runout).
  • Mark-up drawings to include requested GD&T.
  • Calculate when a hole/shaft is out of positional tolerance.
  • Calculate the effects of Max Material Condition, Least Material Condition, Max Material Boundary and Least Material Boundary.
  • Identify placement of Feature Control Frame.
