摘要

在電腦輔助設計裡，一個設計的形式建構，對設計者而言，其邏輯通常是直覺地進行修剪、差集、聯集、拉伸……等，這與程式編寫者的腳本語言有相當的落差；然而參數化設計在即時回饋、修改連動與複選方案的演算……等眾多優勢，使設計者有向參數化邁進的趨勢。而因應本研究所採用的參數軟體特性，研究中得以將繪圖步驟與參數元件之間進行類比，並以「形構邏輯」為探討，進而成為設計檢視的模式。研究結果發現，在接頭形式建構的過程中，所選用的參數軟體－蚱蜢（grasshopper）因為使用圖像化元件的串接關係，而得與繪圖建模的步驟概念銜接，適於不具備程式背景者的設計學習，有助於本研究以參數化來發展接頭設計；最後該核設計成果為數條線段交會下，自動產生的接頭構造體；該構造體最後以展示台的形式呈現，以版面展示自身的設計過程。

In the field of computer aided design, the drawing of computer model is an intuitive way for designers, they modify the computer model directly through some skills such as split, trim, pull or extrude; but there is a gap by contrast with script language users, the computer model produces are work with directly perceived through senses. However, parametric design has a lot of advantages on the issues of immediate feedback, linkage effect, feasible solutions, et cetera. Leading designers have a trend toward the way of parametric design. In response to the characteristics of the parameter software, the writing of this research process attempts to discuss the simulation between drawing process and parameter components with ＂modeling logic＂. The results of this study show that the operation of the parameter software uses associative modeling as a linking configuration, thus it could be compared with the modeling steps and is helpful to the development of joints design; then the modeling logics are more easily converted into parameters by designers who don't have the ability of script language. Finally, the result of the design is presented in the form of a display table called ＂automating nodes＂ -the connecting points at which several lines come together, showing the points in parametric design.
