How to add "Construction Phase" to BIP Properties in IFC


  Product(s): OpenBuildings Designer  
  Version(s): CONNECT Edition & 2023  
  Area: Import/Export  
  Subarea: IFC

Problem Description: 

The User wants to add a "Construction Phase" sub-property to the BIP Properties in IFC.

Steps to Resolve

1.    Open "IFC_MappingScript.ifc2x3.set" using text editor software (or lightweight code editor). The default folder path is C:\ProgramData\Bentley\OpenBuildings 2023\Configuration\Datasets\("Dataset_Name")\Setting. 
2.    In the "TypeID", go to the end of its line and press Enter, then input this: "Construction Phase" :IfcLabel = DG ("?ObjectPhasing/@Phasing");.
3.    Save and exit text editor software (or lightweight code editor).
4.    To access the backstage, click "File," then click "Export," select "Exchange File Types," and press "IFC."
5.    In the IFC Export dialog, set the model view definition to IFC2x3 CV2.0, then press "Export"; an IFC Export Complete message will appear, allowing you to check for errors and warnings.
6.    Open the IFC file in BIM Vision or other software. If an "overwrite" message appears, just click "Yes".
7.    In 'Properties' under 'BIP,' select the customized object (e.g., steel columns, beams), where "Construction Phase" should already be added to the property.

Note: if you want to do the same for the current IFC4 export, you have to do the same thing in the IFC4 mapping script file.
