ME 6104 Fundamentals of CAD Spring 2005
Goals: To introduce fundamental technologies underlying CAD and
show how they can be used to aid engineering design, not just geometry documentation. To provide an open classroom where students can learn by doing
and relate the course material to their research and experience.

Four homework sets
will be given. Some usage of commercial
CAD systems will be required. For distance
student, homework due dates are 2 weeks after the posted date. For the project, you must prepare a proposal
and a final report to turn in.
Additionally, a project demonstration and in-class presentation will be
required for on-campus students. The
final exam time will be used for the presentations. For those groups that do not have demonstrations, the final
report will be worth 30 % of your grade.
You will need a mathematics package
and/or write curve and surface code, then display the results using computer
graphics. You are strongly encouraged
to find suitable programming environments ASAP (Matlab is recommended, but
MathCAD, Maple, Macsyma are possibilities).
Also, you will need to learn a commercial
parametric modeling CAD system (ProEngineer, IDEAS, CATIA, SolidWorks,
SolidEdge, Unigraphics, Mechanical Designer, etc.).
Topics: Introduction to CAD and geometric modeling, Rigid-Body
Transformations.
Parametric Modeling. 1 week.
Curves and Surfaces (Parametric, Bezier, limited B-Spline) 4 weeks.
Solid Modeling (Mathematical Foundations, Boolean Operations) 2 weeks.
Virtual Prototyping: Variational
Geometry, Features, Tolerancing 2
weeks.
Rapid Prototyping. 1 week.
Policies: Homework assignments are to be completed individually,
although I encourage you to work together.
You MUST turn in your own work!
Projects may be done in groups of 2 to 4, although distance learning
students will probably have to work alone.
Homework and reports are due at the class period. You are encouraged to actively participate
in class.
Syllabus for ME 6104 Fundamentals of CAD
Intellectual Questions
to be Addressed:
• Why are components shaped the way they are?
• How are component shapes described to CAD
systems?
• How can a top-down, product-wide approach to
CAD modeling work?
