Interpret geometric dimensioning and tolerancing (GDT) from orthographic blueprints.

Interpretation should include

• features with and without size
• tolerance zones (e.g., basic dimensions)
• geometric tolerancing categories
• geometric tolerancing characteristics and symbols
• symbols associated with feature control frames
• maximum and minimum material condition (e.g., calculating actual position)
• datums.

Process/Skill Questions

• What are some geometric symbols associated with orthographic blueprints?
• What is the difference between geometric tolerances and standard tolerances?
• What is the importance of a datum?
