ETM 1020 - Engineering Graphics II and Dimensional Metrology
A continuation of ET 1100. Covers 2D and 3D drawing using Solid Edge software, general dimensioning, geometric dimensioning, surface texture, threaded fasteners, and welding symbology. Note, detail and assembly drawings will be created for all the parts of two different products (metric and inch). The focus is on creating accurate 3D geometry and usable 2D production drawings. The dimensional metrology part of the course will cover the verification of general and geometric dimensions using basic measuring instruments.
Requisites: ET 1100 or ETM 101 or IT 101
Credit Hours: 3
Repeat/Retake Information: May be retaken two times excluding withdrawals, but only last course taken counts.
Lecture/Lab Hours: 1.0 lecture, 4.0 laboratory
Grades: Eligible Grades: A-F,WP,WF,WN,FN,AU,I
Learning Outcomes:
- Apply dimensions to parts to affect the part life.
- Apply tracking information for product data management.
- Better visualize objects in two and three dimensions by: constructing three-dimensional geometry using computer aided drafting software and developing two-dimensional engineering drawings from 3D CAD geometry.
