摘要:	建築資訊模型BIM (Building Information Modeling)是一種結合工程圖說與建築過程資料於一個建築模型，提供進階三維幾何功能與視覺化能力，改變了過去僅有圖面資料的數位資訊技術；本研究希望藉由將既有BIM模型於圖紙空間深化產出2D施工圖之過程，探討目前業界尚無法將BIM完全導入之原因。 BIM技術於現今國內尚處應用初期，雖具有可改善傳統工程介面衝突難以提前發現、減少變更設計發生機率等優點，但目前尚無一套標準的流程與配套軟體，國外主流的軟體與國內實際工程尚有出入，技術尚未純熟，因此造成目前使用BIM技術導出施工圖說的工作效率遠遠不及傳統CAD二維圖說繪製，此為目前BIM尚無法取代傳統CAD之原因。此外，BIM技術導入前期所需成本費用較高，加上目前專業人員未普及，使得許多公司使用BIM技術的熱情不高。BIM三維模型資訊多，初次設計建模時所耗時間精力較多，且不能快速看到成果。對於一些特別複雜的施工結構，如採用BIM進行設計，需要處理大量的邏輯關係，對於設計員在短時間內無法在設計過程中一次理清，同時由於當今工程建設的工期非常緊迫，設計人員假如使用BIM軟體將可能無法如期完成。 ;BIM(Building Information Modeling) is a type of digital modeling combining engineering drawings and construction data, providing 3-dimensional functionality and visualization, an information technology altering plots of construction documentation in the past. The research aims to utilize present BIM file and further develop in drafting space in order to issue construction drawing plots, to discuss the challenge remain to fully implement BIM in practical projects among construction industry. 　　BIM technology is currently under initial application domestically, despite the feature to perform clash check, which improve hidden design issues of engineering interface, and reduce design alternation afterwards, still there are no standard procedure and assisting software of BIM implementation. The foreign main stream software applied still different from domestic projects, also considering BIM technology still immature, causing the efficiency of BIM generated construction drawings far left behind present 2-dimensional CAD drawings, hence BIM yet to replace CAD drafting as a practical procedure. 　　Besides, the higher cost of starting implementation of BIM procedure and standards, and lack of related professionals or specialists are resulting negative impression among firms and companies of the industry. The nature of BIM consists of large amount of data, also longer time to build an initial complete model, and hard to review the results instantly. Consider complex design and construction, BIM procedure requires logical engineering sequence and knowledge, it’s challenging for designer to organize so to develop at once in a short period during design process. Regarding current compressed construction scheduling, BIM draftsman may fail to deliver complete and quality drawings.
