Course Description: Focuses on foundational Computer-Aided Design (CAD) techniques such as 2D drafting and simple 3D modeling, along with basic Computer-Aided Manufacturing (CAM) processes such as generating toolpaths for devices like laser cutters or 3D printers. Practice creating toolpaths, managing files, and using measurement feedback to refine digital models, emphasizing clear, organized workflows aligned with modern manufacturing practices.

Prerequisite: None.
Meets FQE Requirement: No
Integrative Experience Requirement: No

Student Learning Outcomes

Produce 2D and simple 3D designs using standard drafting conventions.
Prepare CAM toolpaths for devices such as laser cutters or 3D printers, adjusting key parameters.
Interpret measurement data to update digital models for improved fit or function.
Organize files effectively, maintaining clear revision histories and consistent naming schemes.

Course Contents
