本文擬針對逆向設計程序中，實體造型掃描為3D網格模型後，因資料龐大而難以後續編輯處理的問題，提出導人多層次分割曲面的半自動擬合演算法。以Bezier曲面擬合方法為基礎，配合三維多階層局部分割曲面技術，產生多層次漸進擬合曲面。藉由初步的手動設定拓樸網格，產生擬合曲面集合，達到使3D網格模型轉換為曲面模型的目的。降低設計師與學生學習及應用逆向設計的門檻，減少文創自由造型設計的限制，以提昇創意發展的效率。

This paper intended for the reverse design, modeling after scan to 3D meshes, difficult to follow because of data editing and processing issues, proposed import semi-automatic fitting of multi-level segmentation surfaces. Based on the Bezier curve fitting method, with the local division surface technology of three-dimensional class, multi-layer progressive fitting surfaces. Through initial manual topology, to make 3D model conversion for surface models. Reduce designers and students to study and application of reverse design gateway to reduce the limits of creative freedom design, to enhance the efficiency of the creative development.
