This course focuses on learning the fundamental principles and practices of drafting according to international standards using CAD software. Students will gain hands-on experience by creating drawings of various mechanical components, such as bolts, nuts, and gears, while learning how to properly indicate tolerances and surface finishes on the drawings. The course will culminate in a challenging project: drafting a complex mechanical device, a gear pump.
The course is taught by teachers with practical design experience at leading automotive and general machinery manufacturers. Their expertise in drafting mechanical components and layouts for new product development will enrich the learning experience.

Students will develop the ability to accurately understand and apply mechanical drafting rules based on international standards (JIS), correctly represent design intentions such as tolerances and surface finishes using CAD, and interpret and convey the meaning of technical drawings.
Through CAD drafting, students will learn to calculate and accurately represent critical design information such as planar features, geometric tolerances, and gear module dimensions. They will also acquire the skills to decompose 3D shapes into 2D CAD drawings, taking manufacturing processes into consideration, and evaluate these drawings for completeness and accuracy.
The course aims to foster an interest in everyday mechanical systems, such as automobiles, bicycles, and vacuum cleaners, helping students understand how the specialized knowledge of mechanical engineering is connected to tangible products through drafting. This understanding will further enhance their interest and motivation in the field of mechanical engineering.
Students will also learn that incomplete, unclear, or potentially misleading drawings can exist, even in CAD drafting. They will develop an attitude of striving to create clear, accurate, and well-structured drawings that effectively communicate the required information.
By mastering drafting techniques and proper use of CAD tools, students will gain the skills needed to produce professional, precise, and visually appealing technical drawings in accordance with drafting standards.

Students will acquire the skills to perform mechanical drafting in compliance with international standards (JIS) using the latest CAD software widely utilized in manufacturing industries. Building on the drafting principles learned in Introduction to Mechanical Drafting I, this course will focus on how to apply those principles through CAD tools.
The course will consist of a lecture-based format in the first half and hands-on practice in the second half.

In the field of manufacturing, computer-aided design (CAD) is now more commonly used than hand-drawing. Drawings based on international standards function as a kind of "language" that conveys not only shapes but also accuracy and design functions. Drafting rules are as important as grammar in language, so let's learn how to use them correctly.
