Clay sculpting is one of the skills that can be acquired through learning and training. In a traditional method for learning to sculpt a clay model, learners tend to use 2D images as references for sculpting their works. In this paper, we propose an alternative method for learning to sculpt a clay model using the AR technology to provide different views of a clay-sculpting 3D model. It can increase learners' perception, attention, and understanding of proportional details of reference models since they could interactively view a reference model in 3D. There are 2 modes for viewing a 3D model which are a normal 3D and AR mode. The proposed tool is mainly developed with Unity, Autodesk Maya, and Clip Studio Paint. The evaluation of this tool is done on 30 university students who are currently studying in the multimedia and animation field. Participants are divided into 2 groups. Each group is further split into small teams of 3 persons. In each round during an experiment, we swap a turn of using the application in each group. A questionnaire is used to obtain feedback on our tool after experiments are finished. The result shows that participants have positive opinions about our tool. They tend to prefer viewing a 3D model in a normal 3D mode than an AR mode. In conclusion, our proposed application is a great learning assistance tool for clay sculpting.
