ENME 414 Computer Aided Design
Homework Assignment 5 - Dimensioning and Tolerancing
Due 9:30 am, Tuesday, October 8, 1996

Statement: Concurrent engineering, a new concept developed recently, has received
great attention in the process of product development. Concurrent engineering means
concurrence of design and manufacturing. Under concept of concurrent engineering,
product design and product manufacturing are merged in an intimate way.
As a result, concurrent engineering calls for system integration. UNIX -based
CAD systems are in general used. Although these systems are expensive, they provide the
product development team with powerful tools. Large corporations are willing to pay the
initial cost in the first place and are expecting to get significant capital return in terms of
speeding up the design and manufacturing processes. In this homework assignment, you
are asked to use UNIX-based CAD system, called Pro/ENGINEER, to complete the
engineering drawings.

Assignments: Create the front and sectional views of the two parts shown below using
Pro/ENGINEER. Dimensions and tolerances are needed based on your judgment. In
addition the rendered isometric image must also be created. Make use of the software's
features to limit the amount of work you need to perform.
