In recent years, with the rapid development of mobile devices and digital network technology, digital education has become the mainstream trend of modern education. However, the discussion on the integration of visual art courses into 3D drawing apps is extremely rare. 3D painting is the foundation of visual art courses and has an important influence on students. Therefore, this research designed a visual arts curriculum for middle grades in elementary schools. The curriculum planning is redesigned and drafted, mainly focusing on the curriculum content combined with 3D drawing APP, so that the proposed curriculum can be integrated into the existing classroom for research and analysis. The characteristic of 3D drawing APP is that it is simple and easy to learn and allow students to unleash their unlimited creativity in the drawing process.
