1. Lesson Plan
Course Number and Title: WDT 110 – Industrial Blueprint Reading
Module/Unit: Module A – Industrial Blueprint Reading Fundamentals
Module/Unit Description: This module provides students with the opportunity to build the knowledge, and skills required for reading,
understanding and interpreting various blueprint reading applications, for the manufacturing and construction industries. Emphasis is placed a
student building their knowledge and skills in math, interpreting lines, views, dimensions, weld joint configurations and weld symbols, for various
industrial blueprint reading applications. Upon completion, a student should be able to read and interpret blueprints for various fabrication
applications, in the manufacturing and construction industries.
