ECAD 2020 - Geometric Dimensioning and Tolerancing

Credits: 3
Hours/Week: Lecture 2 Lab 2
Course Description: This course provides in-depth coverage of form, orientation, runout, profile, and location tolerances. Topics include analyzing production drawings, investigating inspection procedures, and calculating and specifying tolerances. In the lab portion of this course, students will investigate tooling, machining and inspection aspects of GDT and use CAD to apply symbols to drawings.
MnTC Goals
None

Prerequisite(s): ECAD 1020  or instructor consent.
Corequisite(s): None
Recommendation: ECAD 1070  and ability to add, subtract, multiply, divide, and calculate simple percentages with the use of a calculator.
