現代科技日新月異，人們在家居設計中越來越講究，但進行家居室內空間設計時常會面臨困擾，花費大量的時間思考如何擺設家具物件，家具物件與空間大小是否合適或家具間相互位置是否恰當，研究顯示，人類視覺自然成像3D的效果大於2D成像，少數人會繪製2D設計藍圖，但對於多數人繪製設計圖較為困難，一般使用者時常會委託專業人員進行設計，而專業的人員使用各類型的專業軟體進行設計，繪製建築模型有建築相關軟體，電腦動畫有其相關軟體，雖使用3D建模工具可提升設計速度，也可以減少錯誤，建築物在建築軟體中設計後建造的過程中並不會將家具物件放入建築物中，在建築物設計完成蓋好後，在建築物的維管階段才會放入家具，故不會在建築軟體及繪製家具物件的電腦動畫軟體中進行家具物件的編輯，目前亦無針對家具在維管階段與BIM如何整合的研究。
模型檔案在軟體之間轉換有其相容問題，模型資訊可能在轉換過程中有遺失，多數的3D建模軟體較常使用FBX(FilmBoX)格式來進行模型檔案的轉換， FBX格式為商業開發格式，雖在商業界使用率高，但模型檔案文件的解析及修改不易，本研究使用通過ISO標準的COLLADA(COLLAborative Design Activity )格式取代FBX格式進行模型資訊處理，透過對COLLADA進行檔案格式規範的研究，解析其對於3D模型的資訊處理，最後將由各自不同專業軟體導出的模型文件匯入至遊戲引擎進行呈現，在遊戲引擎中，使用者可以進行家具物件在建築中的維護管理，在系統中進行模擬家具的購入、汰換、移動、旋轉，以提升互動性，將來自不同專業軟體的模型整合以提升建築及物件的擬真度。

In today’s life, people are often faced with many challenges when designing their home. Professional staff usually use various types of professional software to do designing, but the software belongs to their own professional field. There are architectural software to draw building models. Also there are computer animation software. Using 3D modeling can improve speed of the design process and eliminates errors. However, furniture won’t be placed before the building has been built. When the building has been built, the furniture will be placed for the facility management and maintenance phase. So, the furniture assets won’t be edit in the architectural software or computer animation software. There are no research for the combination of the furniture and BIM for or the facility management and maintenance phase.
When transferring the 3D model between different software, the model data may lost. Most 3D software chose FBX(FilmBoX) format to transfer their model files. FBX format were usually be used in 3D model field, but FBX format were developed as a commercial format. Also, the FBX format can’t be read and analyze easily. The study used COLDADA (COLLAborative Design Activity) format to replace the FBX format. COLLADA format had passed the ISO Certification. With the analysis of how COLLADA format do data processing, the study presents an interactive home design application in 3D game engine. In 3D game engine, user can do furniture facility management and maintenance in building. User can simulate purchase, replace, move, and rotate furniture in the system.
