Enhancements

• IFC Import: better handling of invalid date values
• IFC Import/Export: Improved import/export of lines and points. Simplebim is now able to visualize also the point geometry. The point geometry is exported back to IFC as it was in the original model. Appearance of the lines and points is read correctly, if available.
• IFC Import/Export: The layer assignment name of 2D geometry is now read correctly in the IFC import and exported back to IFC.
• Proximity tool (beta): The tool is optimized for performance. The usability and documentation are enhanced. Connections are now created in both directions. The connection properties can be viewed and connected objects visualized in the Tree palette.

Fixes

• IFC import: fixed handling of date, datetime and time of day values in IFC4.3 models
• IFC export: fixed exporting of IfcElectricVoltageMeasure, was exported as IfcReal before
• Classification: fixed handling of various properties of IFC classification objects in IFC4.3 models
• Calculate Properties -tools: fixed bug that caused the calculation to fail if a lot of objects were calculated with a simple formula, because in this scenario Windows resource handles were consumed much faster than they were released.
• IFC export: bug fixed in exporting IFC4 models that have objects that use IfcIndexedPolygonalFaceSet in their geometry. The IFC export crashed in such cases.
• IFC export: bug fixed in exporting backslash characters to IFC. A single backslash character needs to be escaped to \ but it was escaped to \\ instead.
• IFC export: bug fixed in exporting the Layer Assignment Name for objects that existed in previous IFC versions but were deleted from the IFC4.3 schema.
• IFC import: bug fixed in importing type object names for doors and windows
