Interpreting Technical Drawing

MODULE DESCRIPTION

This module provides a review and experiential exercises in interpreting technical

drawings since they function as an important language in the manufacturing world.

MODULE OBJECTIVE

This module introduces students to the various sources of information found within

technical drawings and provides practice interpreting various projections. After completing this module, students should be able to identify orthographic, isometric, and

sectional views and interpret key information on technical drawings.

PERFORMANCE CRITERIA

• Given a technical drawing, the student will be able to identify, correctly label, and

give reasons for each basic element and line type within the drawing.

• Given a technical drawing, the student will be able to identify and label the basic

orthographic projections with 100% accuracy.• Given drawing paper and an isometric drawing of an object, the student will be

able to sketch the top, front, and side views.

The Isometric View


30°

30°

Isometric views are unquestionably the most common of the

pictorial views. The X- and Z-axes (width and depthrespectively) are drawn at 30° from the frontal plane. Theheight of the object (Y-axis) is 90° to that plane. The resultis that true 90° angles are represented by both 60° and 120°angles, but never are they shown as what they are. Try tofind a true 90° angle in the drawing above.
