A Tutorial Guide to Mechanical Desktop provides a step-by-step introduction to this software, with commands taught “in context.” Students make and assemble two complete projects as they follow step-by-step instructions to learn commands and techniques. As they progress, individual steps for common actions are no longer provided, so students can apply what they have learned by completing sequences on their own. This carefully developed pedagogy reinforces the cumulative learning approach and supports readers in becoming skilled Mechanical Desktop users. An excellent selection of exercises allows the student the opportunity to practice their skills.
