什么是建筑BIM正向设计?
What is building BIM positive design?
1.可视性，传统的设计是在二维平面上进行，而BIM技术通过三维空间中进行设计，达到所见即所得的效果，有效提高了整个建筑设计、建设和管理过程中工程内容的全面性和准确性。
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.协调性，通过BIM技术协同设计的并行工作优势，可以保证各个专业间的信息传递及时有效，实现各专业之间设计过程的高度协调，更加高效地把控项目设计的进度和质量[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.模拟性，BIM技术不仅对建筑实体进行模拟展示，还能在设计阶段进行有效定网站建设  伺服液位仪  防撞墙模具 唐山护栏  钢纤维 天津除甲醛  保定铝型材模拟。如建筑设计过程中的能耗分析；人员移动模式以及流动空间需求；进行火灾动力学模拟器能模拟和建筑风环境分析等，可以极大的提高建筑的各个方面的效能。
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.优化性，建筑设计过程伴随着不断地优化和修改，通过BIM技术的信息共享系统便于各专业及时地调整方案，调整后的模型会自动更新，减少改图时间，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.可出图性，由于各个专业，各个阶段的成果是同一BIM模型，例如：初步设计阶段时BIM模型可通过平面剖切形成模板图等，所以保证了各个专业之间设计图纸的一致性，消除了传统制图过程中的“错、漏、碰、缺”问题，提高了出图质量。
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.
