Release 22.1.0.0 for Revit 2022
General:
This version contains multiple updates and improvements over the default Revit IFC for Revit 2022 out-of-the-box. The list below describes various improvements and bugfixes since the latest release of 21.2.1.0.
Bug Fixes:
Export bug fixes:
- Known issue from 21.1.0.0 "Combination of a section box in the current view and the use of option Use active view when creating geometry may cause certain walls that are cut by the section box to fail during export resulting of missing some geometries." has been fixed.

- Fixed issue of failing to export when option to export links as separate IFC for model stored in the cloud.
- Fixed issue of wrong geometry exported when there are cuts on a slanted wall.
