What’s new for IFC for Revit 2016 v16.5.0 and IFC for Revit 2017 v17.2.0:


– Finished French localization.

New Export Functionality:

– Use "Reference Level" as the base level of the element when exporting certain MEP components.

– Support export of mass density units.

Export Bug Fixes:

– Export rooms and areas even if they have improperly closed internal boundaries.  Note that the IfcSpace created may then be missing expected interior holes.

– Fix error when exporting some 0 height walls when they have associated parts.

– Only associate a door or window with one opening, even if the door or window is inserted into multiple walls, as per the IFC standard.

New Import Functionality:

– Add an API option that allows for always reading in bounding box information, even if the entity has a Body representation.

– Allow reading in curve information that's not contained in the Axis representation, to allow for wireframe import.

– Map IfcOutletType and IfcProtectiveDeviceType to Electrical Fixtures and Specialty Equipment, respectively.

– Improved support for IFC2x and IFC2x2 files.

– Support proper scaling of mass density units.

Import Bug Fixes:

– Don't complain about missing IfcOwnerHistory for IFC4 files.

– Properly scale metric bounding boxes so that they are the correct size.

– Stop ignoring some IfcGroups (and IfcSystems) that weren't included in the structure as Revit previously expected.
