EGR 165 - Introduction to Engineering Graphics

Credits: 4
Instructional Contact Hours: 6

Studies the graphic language applied to mechanical and civil engineering design. Develops skills in orthographic projection, multi-view drawings, isometric drafting, sectioning, auxiliary views, revolutions, developments, ANSI dimensioning, and tolerancing, annotation and descriptive geometry. Uses computer-aided drafting and analysis. Credit can be earned in EGR 165 or EGR 166  but not in both.

Prerequisite(s): MATH LEVEL 5
Corequisite(s): None
Lecture Hours: 30 Lab Hours: 60
Pass/NoCredit: No

Outcomes and Objectives  

  1. Produce multi-views of single mechanical components using orthographic projection.
    1. Make measurements with inch and metric scales throughout the course
    2. Draw geometric constructions as used on engineering drawings
    3. Draw technical sketches using the principles of orthographic projection to construct multi-view and isometric drawings of objects with normal, inclined, oblique, cylindrical, and other types of surfaces
    4. Use standard drafting instruments, pencils, and CAD
    5. Letter multi-views of single mechanical components.
  2. Construct sectional, auxiliary, and revolution views of single mechanical components.
    1. Select and apply conventional practices of projection, sectional views, intersections of surfaces and solid geometric shapes
    2. Perform white printing and make copies of student executed original plots
    3. Make large format plots of drawings on a plotter
    4. Use standard drafting instruments, pencils, and CAD.
  3. Dimension mechanical components.
    1. Draw dimensioned, toleranced and annotated, drawings of parts using the latest ANSI standards
  4. Calculate tolerances for assembled mechanical components.
    1. Calculate limit dimensions for various classes of ANSI fit by using the appropriate ANSI tables
  5. Draw and dimension multi-views of an assembly of mechanical components using orthographic projection.
    1. Make measurements with inch and metric scales
    2. Draw geometric constructions as used on engineering drawings
    3. Draw technical sketches using the principles of orthographic projection to construct multi-view drawings of objects with normal, inclined, oblique, cylindrical, and other types of surfaces
    4. Draw a set of project working drawings of an assembly of parts and the detailed individual parts. Examples may include tools, jigs, fixturing, injection molds, etc.
  6. Construct views and projections of elements using principles of descriptive geometry.
    1. Draw solutions to spatial relationships between points, lines, and planes by applying methods of descriptive geometry
    2. Construct graphical analysis to determine displacements, velocities, and/or accelerations, of mechanical parts
    3. Draw primary auxiliary projections
    4. Construct graphic revolution of views about principle axes of projection
