Included Modules

1. Introduction to Mechanical Print Reading: This is the first lesson in the Mechanical Print Reading Course. This introductory lesson trains the learner to identify the various parts of mechanical drawings and their components.
2. Lines Used in Mechanical Print Reading: This is the second lesson in the Mechanical Print Reading Course. This lesson explains the types of lines used in mechanical print reading and what they represent.
3. Dimensions in Mechanical Print Reading: This is the third lesson in the Mechanical Print Reading Course. This lesson explains the use of dimension and extension lines in mechanical print reading, and how to calculate dimensions, tolerance, and limits. The use of surface finish designations is also discussed.
4. Orthographic Projection: This is the final lesson in the Mechanical Print Reading Course. This lesson trains participants in the use of orthographic projections in mechanical print reading. Pictorial drawings and various views used in mechanical print reading are demonstrated.
