Gravity Sketch軟體予以在VR沉浸式環境中，繪製、導入及導出3D物件，此種使用方式在造型設計創作中，提供較2D圖面繪製更直覺的立體感，與一般3D建模、製作物理模型相比，能更方便與快速的以等比例3D檢視設計。
本篇論文以「透過設計的研究」（Research Through Design）的方法，透過設計實作、體驗、紀錄、修正，探討並整理出Gravity Sketch在二輪電動車設計流程中的應用方式與在前期的「設計及發想」階段內，Gravity Sketch如何發揮成效。在研究過程中比較Gravity Sketch在不同情境帶來的影響，並提出使用建議，整理出Gravity sketch應用方式表提供交通工具設計入門者在使用Gravity sketch輔助設計時有一個基礎參考依據，使用項目的搭配、時機則是依個人學習狀況、習慣及需求去做彈性選擇。
除研究Gravity sketch之外，創作上亦挑戰在油電交替時期，基於理性與感性造型分析上，以B快門視覺表現為主題，設計出三輛二輪電動車，以第一提案做出實體模型，測試Gravity Sketch應用於完整設計流程的果效，第二、三案用於驗證操作Gravity Sketch的熟練程度與設計時程的關聯。
經本研究實做，Gravity sketch確實能夠改善原有的設計流程，特別是在「大型」產品設計上，使用Gravity sketch有明顯正向的幫助。在充分掌握Gravity sketch之後，在大型產品設計上會是實用、使設計流程更靈活的新工具。

Gravity Sketch is a new VR software whitch can draw, import and export 3D objects in a VR immersive environment. The way of using it in modeling provides a more intuitive sense of three-dimensionality than 2D drawing, and is comparable to general 3D modeling and able to transfer data for making physical models. In comparison, it is more convenient and quicker to view the design in 3D in equal proportions as we see in the real world.
This paper uses the method of "Research Through Design" to explore and sort out the application of Gravity Sketch in the design process of two-wheel electric vehicles through design implementation, experience, recording, and revision. How does Gravity Sketch work during the "Design and Ideas" phase. In the research process, we compare the impact of Gravity Sketch in different situations, and put forward suggestions for its use, and sort out the Gravity Sketch application method table to provide a basic reference for beginners in vehicle design when using Gravity Sketch to assist in design. Use the combination of projects, The timing is to make flexible choices based on personal learning conditions, habits, and needs.
In addition to studying the Gravity sketch, three two-wheeled electric vehicles were designed in the creation part. Based on the analysis of rational and perceptual modeling, taking the visual performance of Bulb Exposure as the theme, challenging the differentiated styling in the period of oil-electricity alternation, the first case is used to make a physical model to test the effect of Gravity Sketch applied to the complete design process. The second and third cases are used to verify the relationship between the proficiency of Gravity Sketch and the design schedule.
Through the implementation of this research, Gravity sketch can indeed improve the original design process, especially in the design of "large size" products, the use of Gravity sketch has obvious positive help. After fully mastering the Gravity sketch, it will be a new tool that is practical and makes the design process more flexible in large-size product design.
