Engineering Drawing Fundamentals

Engineering Drawings Fundamentals introduces the fundamental concepts that are required to read, understand, and interpret engineering drawings used throughout the manufacturing industry. Presented in THORS’ highly visual and interactive learning format with many examples, this course assists learners in understanding and interpreting the views, different elements, and dimensioning methods used on engineering drawings.


Learning Objectives

  • Interpret the graphic language used in mechanical drawings for practical applications.
  • Locate the title block, revision block, and drawing zone on a print.
  • Distinguish between different views used to represent an object on a drawing.
  • Identify and understand the meaning behind the diverse elements of a drawing, which includes lines, symbols, and dimensioning types and methods.
  • Verify knowledge retention by reviewing complete drawing examples for the elements and components discussed in the course.
Course Length: 4 HRS
