什么是BIM对象?

在一个数字模型中,一个对象必须潜在地包含描述它的所有数字数据。

这组数据包括允许在数字模型中进行各种表示的几何数据和应在数字模型的各个阶段使用的属性。

这些属性应被用于计算它在各个领域的表现,预测它的行为,评估它对环境的影响,在它的长期运行期间对它进行维护,甚至可能考虑到它的处理和回收。

在BIM&CO平台上,您可以输入以下全部或部分数据。

一个或多个几何图形,用建筑软件的一种或几种格式,对物体进行各种图形表示。
计量数据
各种计算的数据
运作的数据,…
帮助使用、计算、安装和操作对象所需的各种图片和文件等。

 

什么是BIM对象?

通俗来说,BIM对象是指用建筑软件制作的几何模型,并且具有属性。这种设想不适应数字模型的使用。

在通常情况下,BIM对象是用建筑软件(REVIT、ARCHICAD、ALLPLAN、SKETCHUP等)制作的模型,由几何体组成,有固定的,也有参数的,放置在几何模型中的数据具有属性、参数或属性(取决于BIM软件使用的术语)。

如果对象是参数化的,可以包含一个表,表里有这个对象的所有或部分可能的值、类型(例如:一个窗口,有它所有可能的尺寸)。

当这个模型被插入BIM软件中使用时,插入的对象是其所有参数和各种类型。这些参数的名称和用途由所有者根据自己的逻辑来定义。因此,两个相同性质的对象,由两个不同的人创造出来的,没有机会具有相同的属性,使得它甚至无法被计算软件或命名系统使用。

如果说这个族可以帮助创建者在REVIT中进行工作(因为所有的信息都在REVIT族/对象中),那么它不符合BIM战略中能够交换和使用数据的要求,是一种专有的方法。

BIM&CO平台的BIM对象。

在BIM&CO中,数据与几何体是分开的。数据存储在数据库中。几何图形只是对象的一个表示,它可以根据需求整合这些数据的全部或部分。

在BIM中,必须要有结构化的、可靠的、可访问的、最新的数据。这是数字建模世界中最难的一点。数据通常可以从制造商那里获得,但不容易访问,或者总是以令人满意的方式结构化(见属性一章)。

为了解决这个问题,BIM&CO平台允许将信息存储在其数据库中。对象的所有者可以很容易地维护这些信息,并在必要时插入或更新对象时,或在BIM过程中使用。

 

 

What is a BIM object?

In a digital model, an object must potentially contain all the digital data characterising it.

This set of data includes geometric data allowing various representations in the digital model and properties that shall be used at various phases of the digital model.

These properties shall be used to calculate it in various fields, anticipate its behaviour, evaluate its effect on the environment, maintain it during its long operation period, and maybe even take into account its disposal and recycling.

On the BIM&CO platform, you can enter all or part of the following data:

  • One or more geometries in one or several formats of architecture software for various graphic representations of the object
  • Data for sizing
  • Data for various calculations
  • Data for operation, …
  • Various pictures and documents such as those needed to help the use, calculation, installation and operation of the object.

What is a BIM object?

In common use, a BIM object is a geometric model made with an architecture software and that has attributes. This vision is not adapted to the use of the digital model.

In common use, a BIM object is a model made with an architecture software (REVIT, ARCHICAD, ALLPLAN, SKETCHUP, etc.), consisting of geometry, fixed or parametric, and data placed in the geometric model has attributes, parameters, or properties (depending on the terminology used by the BIM software).

If the object is parametric, it can contain a table with all or part of the possible values for this object, the types (for example: a window, with all its possible sizes).

When this model is used by insertion in a BIM software, the object is inserted with all its parameters and various types. The name and uses of these parameters are defined by the owner, according to his own logic. Thus, two objects of a same nature, created by two different people have no chance of having the same properties, making it or even impossible to be used by a calculation software or a nomenclature system. 

If this family can help the creator in his work in REVIT (because all information is in the REVIT family/object), it does not meet the BIM strategy of being able to exchange and use data and is a proprietary approach.

 

A BIM object for the BIM&CO platform

In BIM&CO, data is separate from geometry. Data is stored in the database. Geometry is only a representation of the object that can integrate all or part of this data, depending on requirements.

In BIM, it is essential to have structured, reliable, accessible, and up to date data. This is the most difficult point in the world of digital modelling. Data is usually available from the manufacturer, but not easily accessible or always structured in a satisfactory manner (see chapter on properties).

To address this issue, the BIM&CO platform allows information to be stored in its database. This information can be maintained easily by the owner of the object, and be used when necessary when the object is inserted or updated, or during a BIM process.
