This app consists of 3 parts:
- Holzi's Handbook for Carpenters, the proven reference work from Siebenmark & ​​Hilbert Verlag
- Panel Weight Calculator
- c3cad, the new drawing tool, cabinet, and wood list generator

Who is this book for? A few years ago, I started collecting tricks and tips to publish as comics with Holgi as the main character. Then, I received tons of good advice from colleagues and friends, and it soon became clear that this was a reference work for young carpenters!

Holgi from the comic has made the transition to a book and is now called Holzi. He will guide you into the new world of woodworking.

This book is primarily aimed at apprentices and journeymen carpenters in their first years of work. But it is also intended to support experienced journeymen when new fields of activity arise or when they ask themselves, "Man, how did that go again..."?
