Integrity Check for 3D BIM Model

When you convert it into IFC file format after 3D designing a building using a BIM authoring tool such as Autodesk's Revit, missing objects are often found. In other words, the object you could see in Revit are missing when it is converted into IFC file and then imported it.   To get more accurate modeling result, we need to check the missing data and correct them in Revit.  

           

      Concept of BIM data Integrity Check 

Detailed process of BIM data Integrity Check using performa IC

 

1.

When IFC file is exported after BIM designed, Revit data (NIC file) are generated through Revit Plug-in and the NIC file's Integrity can be checked.






2.

 IFC file is imported in performa IC.






3.

The IFC data are compared with Revit data and their integrity is checked in performa IC.

 4.

In performa IC, the missing data can be detected and the result reported. 

5.

The missing data are checked in Revit by clicking the Integrity Check button. 

6.

The missing data are corrected in Revit.

   Missing Object data expressed in performa IC

Example #1 
You can see the Roof object in Revit, but it is missing after it is exported into IFC file and then imported again in performa IC. performa IC visualizes the missed object in 3D.

 Example #2
You can see the Window mass object in Revit, but it is missing after it is exported into IFC file and then imported again in performa IC. performa IC visualizes the missed object in 3D.

performa IC (Integrity Checker) is mutual BIM data integrity checking feedback system.

 ▶ Functions of performa IC 

• Visualizing property and shape information of BIM model big data. 
• BIM authoring tool's (Autodesk Revit etc.) integrity feedback plug in. 
• Visualizing the missed objects
• Analyzing the integrity objects by type
