Issues

Note

There is an 'unknown issues' with LARGE_MODEL_20210219Architecture.ifc. After an hour it was still busy. The issue is probably linked to the issue we had with NO_INVERSE = False in IFC2JSON.

We can see that the furnitures have been removed by the filtering.

We can also observe an anomaly in the display of Duplex_A_20110907_optimized.ifc with walls above the first level being displayed as belonging to the first level. Actually, the are erroneously defined as part of Level 1 i the original file!

The filtering removed the following elements types:

• Distribution Element(s)
• Other(s) [IfcBuildingElementProxy] for the mailboxes and other items
• Pipe Segment [IfcPipeSegment]

Note

The adaptations to the code of IFC2JON4 (IfcJSON) do not yet bring the expected result for IFC_Schependomlaan and the orginal style is not apparent.
