工程制圖一直被認為是一門實踐性學科，其整合了幾何學、建築、力學、電子制圖等，從而將理論與現實圖像聯系起來，工程制圖能為每個不同形狀、尺寸的物體提供精確的、完整的圖像.通常，即使在開放與遠程教育環境中，工程制圖的教學也是通過面對面的教學模式來進行的.由於其特殊性，一些學習者可能難以想象並解釋這些圖像.然而，尖端的技術使得可以通過在線的方式加強工程制圖的學習.研究者基於建構主義模式開發了一個面向工程制圖教學和學習的網路系統.該系統適用於幾種工程制圖，例如展開圖、刻面圖、等角圖和斜角圖.學習過程包括導論、概念學習、工程制圖方法，以及應用與練習等階段.在導論階段，系統為學習者提供了專題簡介，然後是概念學習階段.系統所提供的學習環境允許工程專業的學生從三維透視、一維透視、平面圖、側立面、正立面等不同角度來觀察物體.經過概念學習階段后，系統將引導學生通過動畫和模擬學習每個專題中制圖方法的不同步驟，學習者也能重復觀察任何剖面.另外，還通過圖像、動畫和視頻等方式展示真實的工程制圖應用案例.最後，為了評價學生的理解能力，在每部分內容後面都附有相關的練習The second section introduces the cai - course - making practice on space analytic geometry. according to teaching conditions of space analytic geometry, it proposes the goal of cai course, select and composes teaching contents, selects proper educational tactics and media. script designing embodies teaching contents and educational tactics, studies the presenting messages on every screen and designs the controls of interaction methods and studying procedures

三角網格模型是逆向工程、快速原型製造、數控加工編程、三維動畫等技術中常用的模型表示方法，模型的質量直接影響到產品的質量，尤其在逆向工程中，直接通過測量數據得到高質量的網格模型幾乎是不可能的。因為，測量數據中不可避免地存在各種噪聲和擾動，因此在滿足幾何精度要求的前提下，對網格模型進行優化調整，以提高模型質量就十分必要。The concept of rsdd can solve the conflict between the infinite precision real numbers of spatial object and the finite precision number systems of computers. then we can preserve the closure of spatial operations and rsdd spatial data types. for the closure of spatial operations about ros, we have studied the intersection between rpos and gained the restructure algorithms, i. e., redraw a rpo - line, reconstruct a rpo - plane, and reconstruct a rpo - solid
