什么是建筑BIM正向設計?
What is building BIM positive design?
1.可視性，傳統的設計是在二維平面上進行，而BIM技術通過三維空間中進行設計，達到所見即所得的效果，有效提高了整個建筑設計、建設和管理過程中工程內容的全面性和準確性。
1. Visibility. Traditional design is carried out on a two-dimensional plane, while BIM technology achieves the effect of what you see is what you get by designing in three-dimensional space, effectively improving the comprehensiveness and accuracy of the project content in the whole process of architectural design, construction and management.
2.協調性，通過BIM技術協同設計的并行工作優勢，可以保證各個專業間的信息傳遞及時有效，實現各專業之間設計過程的高度協調，更加高效地把控項目設計的進度和質量[5]。
2. Coordination. Through the concurrent work advantage of collaborative design with BIM technology, it can ensure the timely and effective information transmission among various disciplines, achieve high coordination in the design process among various disciplines, and more effectively control the progress and quality of project design [5].
3.模擬性，BIM技術不僅對建筑實體進行模擬展示，還能在設計階段進行有效定網站建設  伺服液位儀  防撞墻模具 唐山護欄  鋼纖維 天津除甲醛  保定鋁型材模擬。如建筑設計過程中的能耗分析；人員移動模式以及流動空間需求；進行火災動力學模擬器能模擬和建筑風環境分析等，可以極大的提高建筑的各個方面的效能。
3. Simulation. BIM technology can not only simulate and display building entities, but also effectively simulate them in the design phase. For example, energy consumption analysis in the process of building design; Personnel movement mode and mobility space demand; The fire dynamics simulator can simulate and analyze the building wind environment, which can greatly improve the efficiency of all aspects of the building.
4.優化性，建筑設計過程伴隨著不斷地優化和修改，通過BIM技術的信息共享系統便于各專業及時地調整方案，調整后的模型會自動更新，減少改圖時間，提高效率。
4. Optimization. The architectural design process is accompanied by continuous optimization and modification. The BIM technology information sharing system is convenient for all disciplines to adjust the scheme in time. The adjusted model will be automatically updated to reduce the time for drawing modification and improve efficiency.
5.可出圖性，由于各個專業，各個階段的成果是同一BIM模型，例如：初步設計階段時BIM模型可通過平面剖切形成模板圖等，所以保證了各個專業之間設計圖紙的一致性，消除了傳統制圖過程中的“錯、漏、碰、缺”問題，提高了出圖質量。
5. Plottability. Because the achievements of each profession and each stage are the same BIM model, for example, the BIM model can form a template drawing through plane cutting in the preliminary design stage, so the consistency of design drawings among various professions is ensured, the problems of "errors, omissions, collisions and defects" in the traditional drawing process are eliminated, and the quality of the drawing is improved.
