User innovation is attracting attention, and there is an urgent need to educate digital human resources to use digital fabrication equipment. However, there are many 3D CAD lectures in the field of education to foster digital human resources, but the emphasis is on 3D CAD software operation, and there is little discussion on creativity. This study focuses on creativity education for hand-drawn 3D CAD. Specifically, we investigate " the ability to realize 3D data shapes" and " the ability to express 3D data shapes. The method is to divide the class assignment into two cases: hand-drawn three-view drawings and free hand-drawn drawings, and later compare the 3D data created by 3DCAD in each case. The results show that hand-drawn three-view drawings improve the feasibility of the 3D data, but the expressive power is average except for some parts. Next, the free hand-drawing tends to improve the expressive power of the 3D data, while the realization power of the 3D data shape is average except for a few parts. The conclusion is that hand-drawn trihedral figure do not improve creativity more than freely drawings.
