准备架构模型以在Unity中更好地实现BIM可视化
Now it’s easier for AEC professionals to use the Unity platform to create real-time experiences. When you convert your CAD model to Unity, you can use Tridify BIM Tools to visualize your project, and keep your BIM data attached to your 3D models.
现在，AEC专业人员可以更轻松地使用Unity平台创建实时体验。 将CAD模型转换为Unity时，可以使用Tridify BIM Tools可视化项目，并将BIM数据附加到3D模型中。
Architecture, engineering and construction (AEC) professionals can use the Unity platform to create an immersive 3D experience, allowing them to visually differentiate their work from the competition.
建筑，工程和建筑(AEC)专业人员可以使用Unity平台来创建沉浸式3D体验，从而使他们在视觉上将自己的作品与竞争对手区分开来。
For an architectural model to be useful, beyond establishing the basic geometry of your project, it should let you experiment with tiling, flooring, lighting etc. But if wall objects and floor slabs aren’t defined correctly, you can’t apply or replace materials efficiently.
为了使建筑模型有用，除了建立项目的基本几何图形外，还应该让您尝试使用贴砖，地板，照明等。但是，如果未正确定义墙对象和楼板，则无法应用或替换材料高效。
When you convert your CAD model to Unity, you can use Tridify BIM Tools – available free on the Asset Store – to get automated lighting, material, colliders and building information modeling (BIM) data attached to your 3D models. In Unity, you can click on a component and access the associated BIM data right away – so you can visualize your AEC project in real-time 3D.
将CAD模型转换为Unity时，您可以使用Tridify BIM工具 (资产商店免费提供)来获取附加到3D模型的自动照明，材质，对撞机和建筑信息模型(BIM)数据。 在Unity中，您可以单击一个组件并立即访问关联的BIM数据-这样您就可以实时3D可视化AEC项目。
Instead of spending days – or weeks on large-scale projects – cleaning and fixing your model, or even rebuilding it from scratch, just a few hours spent preparing your model will ensure highly usable files for 3D visualization.
无需花费数天或数周的时间来进行大型项目的清洁和修复模型，甚至从头开始重建模型，只需花费几个小时来准备模型，即可确保3D可视化文件的高度可用。
为虚拟化准备BIM模型：最佳实践 (Preparing the BIM model for virtualization: Best practices)
A good model is the foundation for a digital twin that can be used throughout the building’s life cycle. In this way, you’ll get the best possible use from the Tridify BIM Tools, coupled with a smooth workflow. Invest in creating a good model and your model will become a valuable asset, serving as the basis for lots of future use cases.
一个好的模型是可以在建筑物的整个生命周期中使用的数字孪生的基础。 这样，您将可以从Tridify BIM工具中获得最佳利用，并获得流畅的工作流程。 投资创建一个好的模型，您的模型将成为宝贵的资产，成为将来许多用例的基础。
When you receive a BIM model from an architect, make sure it follows the following five main modeling practices:
当您从架构师那里收到BIM模型时，请确保它遵循以下五种主要建模实践：
- Mark every object as an appropriate element type (i.e., tag doors as “door element,” walls as “wall element,” etc.). As you can select objects by type, this will help you find objects fast, so you can, for example, easily create colliders or remove unnecessary ones. 将每个对象标记为适当的元素类型(即，将门标记为“门元素”，将墙壁标记为“墙元素”，等等)。 因为您可以按类型选择对象，所以这将帮助您快速找到对象，例如，您可以轻松创建对撞机或删除不必要的对撞机。
- Separate multi-storey buildings into storeys. Each storey should contain floor slabs, a ceiling, and everything in between. Architects’ models don’t usually contain ceiling elements; in Tridify, upper floor slabs serve as ceilings for visual purposes. 将多层建筑物分成几层。 每层应包含楼板，天花板以及介于两者之间的所有内容。 建筑师的模型通常不包含天花板元素。 在Tridify中，上层楼板用作视觉目的的天花板。
-
Place all objects and structures on the correct storey. The lighting algorithm takes all the structures into account when you create floor lighting with the Tridify tool.
将所有对象和结构放置在正确的楼层上。 使用Tridify工具创建地面照明时，照明算法会考虑所有结构。
-
Connect walls according to surface materials. This enables different materials to be visualized on each wall section. If the walls are not connected correctly, the wall material layers will be visible on the end of the wall. Ensure separate material layers for each room for elements in common; for example, a wall that continues from the bathroom to the living room might require ceramic tile for the bathroom wall and plaster for the living room wall.
根据表面材料连接墙壁。 这样可以在每个壁部分上看到不同的材料。 如果墙壁连接不正确，墙壁的材料层将在墙壁的末端可见。 确保每个房间都有单独的材料层，以容纳共同的元素； 例如，从浴室延伸到客厅的墙壁可能需要瓷砖用于浴室墙壁，而石膏则需要用于客厅墙壁。
- Specify the material layers for exterior walls, and give the material layers thickness. This lets you specify walls (exterior and interior layers) in different materials (e.g., brick on the outside, plaster on the inside). If all the exterior elements are typed as external objects, you’ll be able to extract the shell of the building. 指定外墙的材料层，并指定材料层的厚度。 这使您可以使用不同的材料(例如，外部的砖块，内部的灰泥)指定墙壁(外部和内部层)。 如果将所有外部元素都键入为外部对象，则可以提取建筑物的外壳。
Following these modeling practices will give you a smooth workflow from architect model to Unity.
遵循这些建模实践将为您提供从架构师模型到Unity的流畅工作流程。
与平台无关的标准 (A platform-neutral standard)
Tridify uses IFC (Industry Foundation Classes) files, an international standard designed to facilitate interoperability and collaboration in the AEC industry. IFC can be exported from any major CAD software, and it allows anyone to exchange digital models across different software. Using IFC files allows data to be combined in Unity – with the same workflow – from different sources: architectural models from ArchiCAD®; heating, ventilation and air conditioning (HVAC) models from MagiCAD®; and furniture models from BIMobject®.
Tridify使用IFC(工业基础分类)文件，该文件是旨在促进AEC行业中的互操作性和协作的国际标准。 IFC可以从任何主要的CAD软件中导出，它允许任何人在不同的软件之间交换数字模型 。 使用IFC文件可将数据以不同的来源在Unity中以相同的工作流程进行合并 ：来自ArchiCAD®的体系结构模型； MagiCAD®的加热，通风和空调(HVAC)模型； 和BIMobject®的家具模型。
As such, IFC files offer a great deal of flexibility and enable the automation of repetitive tasks.
这样，IFC文件提供了很大的灵活性，并实现了重复任务的自动化。
使用BIM数据的Unity工作流程 (Unity workflow using BIM data)
By having object-specific BIM data and scriptable access to it , you can simplify or automate several tedious tasks, solving the problem of repetitive, slow, and error-prone remodeling. You can assign textured materials, light rooms, assign colliders, and perform many other tasks. With Tridify and Unity, you can cut the development time and focus on making your model more interactive.
通过具有特定于对象的BIM数据和可脚本访问的数据，您可以简化或自动化一些繁琐的任务，解决重复，缓慢和易于出错的重塑问题。 您可以分配带纹理的材料，明亮的房间，分配对撞机以及执行许多其他任务。 使用Tridify和Unity，您可以缩短开发时间，并专注于使模型更具交互性。

从BIM到Unity等 (From BIM to Unity and beyond)
Tridify’s technology bridges the gap between BIM and Unity, allowing AEC professionals to focus on designing and creating instead of importing files. By following best practices in model creation, architectural models can easily be converted to Unity with all BIM data intact. Unity’s HDRP then allows you to visualize 3D models with dynamic lighting, materials and more.
Tridify的技术弥合了BIM和Unity之间的鸿沟，使AEC专业人员可以专注于设计和创建而不是导入文件。 通过遵循模型创建中的最佳实践，可以在不影响所有BIM数据的情况下轻松地将架构模型转换为Unity。 然后，Unity的HDRP允许您使用动态照明，材质等来可视化3D模型。
Tridify and Unity together give AEC designers and developers the productivity tools to optimize data and save time while creating real-time experiences. The technology allows 3D immersion, interactivity, a life-like level of detail, and simulation of light, sound and other environmental conditions, all of which contribute to enhancements and efficiencies across the AEC project lifecycle in planning, collaboration, and sales.
Tridify和Unity共同为AEC设计人员和开发人员提供了生产力工具，可在创建实时体验的同时优化数据并节省时间。 该技术可实现3D沉浸，交互性，逼真的细节水平以及对光，声音和其他环境条件的模拟，所有这些都有助于在AEC项目生命周期的规划，协作和销售中提高效率。
