The 3D pen is a tool that can output a melted resin from a pen tip to form a 3D object. In order to shape an object using a 3D pen, it is necessary to practice it and understand how to use it, and many beginners find it difficult to handle. Most of the difficulty is caused by users not understanding the appropriate moving speed. On the other hand, it is necessary to have interactivity in the learning system. In 3D object drawing learning, a learning system using VR/AR capable of displaying three dimensions is desired. In this research, we aim to support learning in 3D object drawing, and proposed and developed a 3D object drawing learning support system with interactivity. Furthermore, the influence of the proposed system and a video learning system on 3D object drawing skill by 3D pen is examined. As the results of the experiments, it was necessary to practice 3D drawing with 3D pen, and it was deduced that interactive learning may be more effective than non-interactive learning after practicing 3D pen. In addition, it was suggested that interactive learning is more likely to make feel that learners improved with respect to speed and drawing related to pen. In 3D pen drawing learning, it was suggested that those who are not good at 3D drawing are more likely to feel that interactive learning has improved their drawing techniques.
