| dc.description.abstract | 近年來，CAD產業日益成熟，而協同設計的觀念更被廣泛地應用在許多CAD系統上，以上游工業設計與下游機構設計之間的接力設計而言，可以提供兩端遠距離的共同設計與討論。接力設計通常使用中介格式作檔案交換，當過程中產生設計變更時，便會遭遇困難，工業設計端的設計變更，易導致機構設計的努力付諸東流。針對此設變傳遞之問題，本研究以三個步驟來進行。
首先，本研究提出一種彈性協同架構，將CAD的結構做分層，使得CAD系統可以輕易地從單機操作轉換成各種協同設計的版本。其次，應用彈性架構，整合CAD與PDM系統成為一個網站平台，使用者可省去安裝步驟，直覺操作，並且解決不同單位跨越設計平台的問題。最後，將彈性架構中的傳遞資料紀錄為設計步驟，藉由保存傳遞資料，達到同步或非同步協同的功能。利用「模型相似性比對」技術，讓協同兩端比較設計變更前後的檔案版本差異，並修改設計步驟以傳遞設計變更，使得機構設計在工業設計設變後得以延續。 | zh_TW |
| dc.description.abstract | Recently, some products have been concentrated on developing distributed CAD systems with collaborative methodologies. Collaboration could provide discussion and co-design between the two upstream industrial design and downstream mechanical design teams. The sequential design starts from industrial design using neutral file as exchange format. When the design change occurs during the process, the following mechanical design can’t access the design contents. According to the problem about design propagation, three steps are proposed in this research.
First of all, this research proposes flexible collaboration architecture, separating the CAD structures into some layers, and make CAD system easier to change its working style from standalone to any other collaborative edition. Second, CAD and PDM system can integrate to from a web platform using the flexible architecture. It is unnecessary to install the CAD system, and users can manipulate models directly, which can solve the problem when design stage is across two different sites. Final, take the recording data passed in the flexible architecture as design steps, and by reserving these data, the design procedures can be recorded and replayed in real-time or afterward. As a result, the synchronous collaboration and asynchronous collaboration can be achieved. System will compare the later input neutral file with the former one by using “similarity comparison” of 3D model, and modify the design stages on former neutral file and apply them into the later neutral file. Thus, the design change can propagate in the mechanical design if it happens in the industrial design. | en |
