Course description and aims
Students in this course learn the basic rules of mechanical drawing and the basics of machine elements and mechanical drawing for expressing such machine and elements as the foundation of a series of design courses. They also learn the basics of drawing with CAD, and deepen their knowledge about machine drawing, and working with 3D printers, machine tools, and the like, in order to acquire knowledge and skills, which will be a foundation of overall design courses.
Dimensional tolerances, Geometric tolerance, Fitting and related standards, Basics of drafting tools and CAD software. Basics of machine elements such as fastening element, shaft element, transmission element.
Student learning outcomes
By the end of this course, students will be able to:
1. Explain the basics of Mechanical Engineering Design and drawing through hand-drawing, and 2D, 3D-CAD of various machine elements. Understand functions, mechanics, work methods, materials of machine elements and manufacturing method of mechanical components.
2. Understand how to use drafting tools and CAD software. Basic rules such as dimensional tolerances, geometric tolerance, fitting and related standards can be explained through practice drafting trace of basic machine elements such as fastening element, shaft element, transmission element.
This subject corresponds to the learning objective of "1. [professional ability] basic expertise".

Competencies that will be developed
| Specialist skills | Intercultural skills | Communication skills | ✔ Critical thinking skills | Practical and/or problem-solving skills |
| ✔ This class aims at learning 4, 6 and 7 of learning objective. | ||||
Class flow
Students will work on three major challenges under one theme for two weeks. Each week, lectures will be given on the functions of mechanical elements, how to draw technical drawings and various precautions. On that basis, students will use CAD software in the second half to do practical work on mechanical drawings. Generally, assignments are completed within the lecture time, evaluated by the instructor, revised as appropriate, and submitted. Assignments are subject to grade evaluation.

Out-of-Class Study Time (Preparation and Review)
To enhance effective learning, students are encouraged to spend a certain length of time outside of class on preparation and review (including for assignments), as specified by the Tokyo Institute of Technology Rules on Undergraduate Learning (東京工業大学学修規程) and the Tokyo Institute of Technology Rules on Graduate Learning (東京工業大学大学院学修規程), for each class.
They should do so by referring to textbooks and other course material.
