TDSN 105 - Reading Engineering Drawings

2 Credit: (0.5 lecture, 1.5 lab, 0 clinical) 2 Contact Hours:

This course includes the basic projection of views, lines, reading scales, isometric and oblique projection, sections, perspectives, threads, title blocks, stock lists, and interpreting the attributes of an assembly and detail in engineering drawings. Students also interpret engineering working drawing measurements and dimensioning as well as interpret engineering drawing notes. This course also contains a brief introduction to geometric dimensioning and tolerancing (GD&T).
OFFERED: summer and fall semesters
