Introduction to CAD Test Preparation
Course Introduction
Introduction to CAD provides students with a foundational understanding of Computer-Aided Design (CAD) and its applications in various engineering and design fields. The course explores core concepts such as drafting, modeling, and visualization, while familiarizing students with industry-standard CAD software. Emphasis is placed on creating and interpreting 2D and 3D drawings, understanding geometric constructions, and employing precision tools. Through hands-on projects and exercises, students develop the skills necessary to design, modify, and analyze digital models, preparing them for more advanced coursework and professional practice in engineering, architecture, and related disciplines.
