Why Specify and Review BIM attributes?

Specifying and reviewing property attributes ensures that elements, or objects, in a building & civil model have all the necessary attributes for architecture, engineering, and classification standards.

Every element in your civil engineering project has BIM attributes that are set as you add to the civil engineering project. You can attach additional sets of attributes as attribute extensions to elements, or objects, in your civil engineering project. When elements include attribute values, the software considers the attributes and associated values as objects. The software uses the objects to search for similar types of objects.

Some of attribute extensions for each object adhere to construction classification standards for the object. Construction classification standards include Industry Foundation Classes (IFC), OmniClass, and UniFormat. Each standard has its own set of object attributes.

Each classification standard collects attributes into a sets. For example, for the IFC standard, there is an Ifc Wall Common property set. It includes attributes such as Reference, Acoustic rating, Fire rating, and whether or not the wall is Load bearing. Another IFC wall entity property set is Wall Properties. It includes the attributes you set when creating the wall, such as Wall thickness and Height. It also includes attributes you can set such as Material and Category.

For each object in your building, you can use the BIM attributes command to select the entities, attach attribute extensions (for example, property sets), and review both the entities and their attributes. Other 3DEXPERIENCE apps can access and use the BIM attributes and attribute extensions attached to elements, or objects, in a project.

You can also use in other applications and viewers the BIM attributes and attribute extensions attached to elements, or objects, in a project. For example, you can export the BIM results to an IFC file format. You can then open the IFC file in Building and Civil Assemblies that supports IFC. Or, you can open the file in an IFC viewer. That exported IFC file includes any IFC entities and their attributes as well as any OmniClass and UniFormat entities and attribute that you set.
