ENGRMAE 52 Computer-Aided Design (2013-2014)

ENGRMAE 52 Computer-Aided Design

(Required for ME. Selected Elective for MSE.)
Catalog Data:

ENGRMAE 52 Computer-Aided Design (Credit Units: 4) Develops skills for interpretation and presentation of mechanical design drawings and the use of CAD in engineering design. An integrated approach to drafting based on sketching, manual drawing, and three-dimensional CAD techniques is presented. Mechanical Engineering and Materials Science Engineering majors have first consideration for enrollment. (Design units: 0.5)

Prerequisites by Topic

Basic math

Lecture Topics:
  • Introductory Concepts
  • Design and Drafting Basics
  • Drafting Basics
  • Drafting I (orthographic & pictorial views, 1st & 3rd angle projection)
  • Drafting II (sheet formats, auxiliary & detail views, sections, breaks)
  • Drafting III (assemblies, bill of materials, fillets, notes)
  • Dimensioning and Tolerancing (rules, centerlines, layout, tolerance stacking)
  • Dimensioning and Tolerancing II (symbols, threads, holes, fits)
  • Geometric Dimensioning and Tolerancing (datums, feature control frames)
  • Solidworks topics (all of the above, plus: basics, sketches, relations, parent/child, modeling, assemblies, parts, drawings, DOF, patterns, surfaces)
Class Schedule:

Meets for 3 hours of lecture and 2 hours of laboratory each week for 10 weeks.

Computer Usage:

The computer is used for half of the lecture time to detail examples of homework, projects, and lecture subjects. In addition students have a three-hour lab where they work on a weekly modeling project using the Solidworks 2004-2005 software package.

Laboratory Projects:

The project is broken down into several small models which are skill specific, and one large project which makes use of the skills learned during the short project.

Professional Component

Contributes toward the Engineering Topics courses and Major design experience for both Mechanical and Aerospace Engineering.

Design Content Description

A final design project is required. All students must complete an assembly design that incorporates mating parts and fasteners. They must also produce a drawing for each part that has appropriate dimensioning and tolerancing, an assembly drawing, an exploded drawing. The emphasis is on proper dimensioning and tolerancing (including geometric dimensioning and tolerancing) so that the assembly is manufacturable, inexpensive, and can be assembled properly. A second component of the final project allows students to use the more advanced features of Solidworks.
