About the author

Since the early 2000s, I’ve worked extensively with Autodesk Inventor and have had the privilege of mentoring others in the art, and discipline, of skeleton modeling. As Founder of Disegno AS and a seasoned Autodesk application engineer, I’ve helped countless advanced users and design teams optimize their CAD workflows. Prior to that, I spent over 20 years as a 3D designer and Autodesk application engineer in the oil and gas industry, where structured modeling techniques proved essential in managing complex assemblies.

My own journey with skeleton modeling began thanks to Harald Knutsen at Meisle 3D Print. He introduced me to the technique and taught me how to use it properly. That foundation became instrumental in shaping how I approach large, adaptive models today and it’s something I’ve carried with me ever since.

Over the years, I’ve seen how powerful skeleton modeling can be when applied correctly. It offers structure, clarity, and long-term flexibility to even the most complex designs. Yet despite its advantages, this technique remains underused often because there’s a lack of clear, advanced-level training material available.

That’s why I decided to write this book.

This guide is for experienced Inventor users who want to bring more structure, intent, and scalability into their modeling workflows. The techniques I share are based on real-world projects and practical experience - not just theory.

Whether you’re an engineer, a CAD specialist, or involved in product development, I hope this book helps demystify skeleton modeling and inspires you to integrate it more fully into your own work.

Welcome to a more robust way of modeling.
