In dealing with communications problems, this paper found through industry interviews that different form communication tools are used during the form phase in accordance with different product types and that external communication is more difficult than internal communication. In practice, communication tools of sketch and 3D computer graphics are most commonly used. While sketch can be used to quickly make a proposal, client understanding is somewhat inadequate. On the other hand, while 3D computer graphics can be used for clear expression, they require more work time on the part of designers. As a result, this paper introduces a communication tool of 2D and 3D integrated computer graphics to integrate the advantages of both types of tools and then assesses the effectiveness of the tool and sketch. Research results for communications effectiveness showed that the efficiency of sketch was increased. In terms of quality and satisfaction, different factors produced varying evaluation results. If computer graphics software can be integrated as one, realize details, and improve the 3D computer graphics capabilities of designer, then 2D and 3D integrated computer graphics can lead to great improvements in communications efficiency, quality, and satisfaction, achieving the advantages of instant feedback and common consensus with client. These results can be used as a basis and a reference for improvements in arts, design education and industry development.
