ENG 122IN - Engineering Graphics and Design with Solid Modeling

3 Credits, 7 Contact Hours
1 lecture period 6 lab periods

Introduction to engineering graphics and the concepts of engineering design. Includes sketching, dimensioning practices and tolerances, computer-aided design (CAD), basic part modeling, and three-dimensional (3D) assembly modeling.

Prerequisite(s): MAT 189  


Course Learning Outcomes
  1. Demonstrate the fundamental concepts and principles of engineering graphics as a language.
  2. Generate hand-drawn multi-view technical sketches.
  3. Apply methods of orthographic projection to produce detail.
  4. Demonstrate the fundamental concepts and principles of the computer-aided design (CAD) system.
  5. Demonstrate the ability to read engineering drawings.
  6. Construct three-dimensional (3D) solid models on a modern CAD system:
    1. Create 3D solid models of complex objects given a multi-view representation
    2. Create solid models of individual parts
    3. Create reference geometry features (planes, axes)
    4. Measure properties of 3D CAD models
  7. Create multi-view, auxiliary and section drawings from 3D solid models:
    1. Use the principal planes of projection and the principal views
    2. Create hidden lines, center lines, etc. based on graphics conventions
    3. Create multi-view drawings from 3D solid models on a CAD system
    4. Represent typical features: e.g. holes, threads, chamfers, and fillets
    5. Create auxiliary views automatically from 3D solid models
    6. Generate appropriate section views
  8. Create dimensioned drawings from 3D solid models:
    1. Understand the basic terminology and geometrical  relationships associated with dimensioning practice
    2. Demonstrate size, location, and coordinate dimensioning
    3. Create dimensioned drawings from 3D solid models
    4. Create complete working drawings including assembly and detailed drawings for a “real-life” object
  9. Apply geometric dimensioning and tolerancing (GD&T):
    1. Understanding and practical proficiency in dimensioning and tolerancing.
    2. Recognize GD&T dimensioning on an engineering drawing
    3. Determine maximum material condition (MMC) and its implications
    4. Calculate bonus tolerance allowances as features deviate from MMC
