Fall 2025 Laboratory Lecture Lower Division
This course focuses on CAD-based modeling and engineering graphics standards (national - ANSI/ASME and international - ISO), including coordinate and geometric dimensioning and tolerancing practices. It covers principles and techniques of three-dimensional surface and solid modeling. This course teaches students how to model real-world engineering objects and assemblies using the capabilities of commercial CAD systems. Conceptual, preliminary and detailed part and assembly models are assigned as exercises to reinforce the classroom lectures. This course teaches the graphics language and standards necessary for engineering students to read, understand, and sign off engineering drawings and documents. Students are required to detail (create engineering drawings) their CAD models, demonstrating their ability to both read and apply graphic standards.
