A 20-day learning journey designed to help you build real CAD skills through daily projects, guided lessons, and hands-on creativity.
Trusted by educators and institutions worldwide, including faculty at Harvard, Stanford, Yale, UCL, and Cambridge. Autodesk Authorized Training Center.
The best way to teach design is by creating something meaningful.
Mastering Tinkercad introduces educators to CAD through hands-on projects that build technical skills while encouraging creativity and problem-solving. Every lesson is supported by step-by-step videos, downloadable PDFs, lesson plans, and instructor resources that make implementation simple.
As you move through the curriculum, you'll gain the knowledge and confidence to guide learners through their own design journey.

Each lesson builds on the previous one, making steady progress feel natural and rewarding.
Learning CAD is easier when every lesson has a purpose.
Over twenty days, you'll move through a carefully structured sequence that introduces new tools, reinforces previous concepts, and gives you opportunities to apply what you've learned through real projects.
Instead of memorizing buttons and menus, you'll understand how the tools work together to solve design problems and bring ideas to life.
By the end of the program, you'll have a strong foundation in Tinkercad and the confidence to keep creating on your own.

No previous CAD experience is required.
This course was created for beginners of all ages who want an enjoyable introduction to 3D design. Whether you're exploring CAD for the first time, preparing for more advanced software like Fusion 360, or looking for a creative way to get into 3D printing, you'll find an approachable, rewarding learning experience.
Lessons are short, practical, and designed to help you make progress every day.
Tinkercad in Twenty Days gives you everything you need to stay engaged
throughout your learning journey.
Because Tinkercad runs entirely in your browser, you can start creating without installing additional software.
The course is designed as a twenty-day experience, but your schedule is entirely up to you.
Many learners enjoy completing one lesson each day, while others move more quickly or revisit lessons as they build new projects. With approximately 30 minutes per lesson, it's easy to fit into a busy schedule.
You'll have lifetime access to every lesson, allowing you to return whenever inspiration strikes.
