摘要

市面上之多數實體模型系統多以參數化的方式建模，此種方式仰賴眾多的資料與數據的導入。即使參數化的設計方式可以降低設計的難度與提高加工時的精確度，但在現今加工業全球化的潮流下，設計圖在異地修改的限制性與檔案交流的不便性就逐漸浮出檯面。

近年來非參數化的建模方式開始興起。此種建模的方式能在缺少實體原本之建構歷程與尺寸限制的情形下，快速修改實體外型，因此是未來CAD/CAM應用的趨勢。本研究提出數個參數化修改之方法，企圖以直覺性方法調整去參數化之實體上之面、稜邊與點，修改該實體之外型，並嘗試實作於Spring Solid System中。

Most solid model systems available in the market are using parametric modeling approach, which relies on a large number of import information. Even though this approach can reduce the difficulties of design and improve the manufacturing precision, the restriction of design alteration and the inconvenience of file exchanges are gradually encountered in the globalization trend of processing industry today.
Therefore, the non-parametric modeling approach began to rise recently. This kind of modeling approach can adjust the outer shape of entities rapidly in the absence of original building history and feature dimension, thus making it become the trend of future CAD/CAM systems. This study proposes a number of methods to modify de-parametric entities in parametric ways, trying to adjust the outer shape of entities by tweaking faces, edges and points of entities directly, and attempt to implement in Spring Solid System.
