- 331 Geometric Modeling for Engineering Applications. I,
II, SS; 3 cr. A junior level course introduces undergraduate engineering students to fundamental concepts in geometric modeling of engineering form, and computer-aided design of shapes, components, and assemblies. Lectures are reinforced by the laboratory experience where students operate modern commercial computer-aided design systems to model and to learn the basics of engineering communication, specification, and annotation. P: ME 231, ME 240, Math 320, CS 302 or equivalent
- Course Prerequisite(s)
- Prerequisite knowledge and/or skills
-
Ability to read and interpret 2D mechanical drawings.
Some exposure to the principles of static loadings.
- Textbook(s) and/or other required material
-
No formal text. Class notes available to students electronically during the semester.
- Course objectives
-
Basic understanding of mathematical models of engineering shapes (curves, surfaces,
solids), artifacts, and assemblies;
-
Introduce students to modern concepts and methods of computer-aided modeling and
design, including parametric and constraint-based techniques;
-
Introduce concepts and standards for employing and specifying shape variability and
tolerancing;
-
Develop familiarity with operating a commercial computer-aided design system,
including ability to recreate (copy), synthesize (from incomplete specifications), analyze
(for geometric and mechanical properties), annotate (using drawings, dimensions, and
tolerances), and exchange shapes, artifacts, and assemblies.
- Topics covered
-
Principles and techniques of 3D surface and solid modeling.
-
Feature-based and constraint-based modeling systems
-
Data transfer between systems
-
Relationship of geometric modeling to manufacturing, analysis and rapid prototyping
-
Development of 2D drawing from the solid model database
-
Design annotation including Geometric Dimensioning and Tolerancing
- Class/laboratory schedule
-
Fundamental concepts and theory are introduced in lectures (two hours per week) and reinforced
with regular homework assignments. The practical skills are developed in the laboratory (two
two-hour sessions per week) and involve 5-7 projects of variable difficulty. Exams (one midterm
and a final) are used to encourage students to review the material and to assess their learning.
- Contribution of course to meeting the professional component
- This course contributes primarily to the students' knowledge of engineering topics, and does provide design experience.
The following statement indicates which of the following considerations are included in this course: economic, environmental, ethical, political, societal, health and safety, manufacturability, sustainability.

-
Geometric Modeling for Engineering Applications introduces our students state of the art techniques and software. The primary intent is to expose students to the tools necessary to design and manufacture products in an economic, safe, and sustainably manner. This course not only exposes our students to principles and practices of 3D modeling but introduces topics in mechanical fastening specifications, and component geometric and positional tolerancing for economic, safe and manufacturable fabrication.
- Relationship of course to undergraduate degree program objectives and outcomes
- This course primarily serves students in the department. The information below describes how the course contributes to the undergraduate program objectives.
-
-
The Geometric Modeling for Engineering Applications course requires students to demonstrate visualization and communication skills as they apply to mechanical engineering component and system design. Students are required to generate static and variation computer-based geometric models. Students are also required to communicate design intent through the creation of models and fully annotated drawings.
- Assessment of student progress toward course objectives
-
Primary forms of assessment are administered tests on the conceptual ideas presented and through several laboratory projects which demonstrate and reinforce the concepts presents. A final team project which requires the student to fully communicate a system design through the creation of computer-based component models, system assembly, and fully annotated drawings is also given.
