Course Title: Mechanical CAD Fundamentals

Course Description:

This course provides an in-depth introduction to Computer-Aided Design (CAD) software used in mechanical engineering for designing, drafting, and modeling mechanical components and systems. Students will learn the fundamental principles and techniques of CAD software, including 2D drafting, 3D modeling, assembly design, and engineering drawing creation. The course will cover industry-standard CAD tools and workflows, enabling students to create detailed and accurate mechanical designs. Through hands-on projects and exercises, students will develop proficiency in using CAD software to solve real-world engineering problems.
