# ECAD 1020 - Interpreting Engineering Drawings

Credits: 2
Hours/Week: Lecture NoneLab None
Course Description: This course is designed to give students an understanding of the concepts required to read industrial blueprints. Topics include sketching, multi-view drawing, symbols, scaling, dimensioning, finishes, screw threads, auxiliary and assembly drawings. Also covered is an introduction to Geometric Tolerancing. Restriction: Closed to students who have already earned credit for ECAD 1023 - Blueprint Reading for Renewable Energy .
MnTC Goals
None

Prerequisite(s): None
Corequisite(s): None
Recommendation: Arithmetic assessment score of 64 or higher or elementary algebra assessment score of 76 or higher OR assessment score/ACT score placement into MATH 0070  or above OR completion MATH 0030  or MATH 0060  with a grade of C or higher. We strongly encourage students who score below 64 to meet with an advisor or counselor to discuss their review and course options PRIOR to Math assessment retesting or registering for a MATH course.
