This application seamlessly replaces the built-in IFC capabilities of Revit 2019. It contains enhancements to functionality and defect fixes provided by Autodesk and Open Source contributors that did not appear in the initial shipping version.
<li>This version contains significant updates and improvements from the previous release 20.1.0.1 and it is mostly equivalent to 21.1.0.0 that was recently released.
216

<li>This version contains significant updates and improvements from the previous release 19.3.0.1 and it is mostly equivalent to 21.1.0.0 and 20.2.0.0 that were recently released.
217
217
<li>The main features are a lot of works done towards IFC4 RV 1.2 certification (currently for Architecture). It is still work in progress though most of the requirements have been implemented in this version.
218
218
<li>The shared parameter files have been consolidated to only 2 files one for the Instance and the other one for the Type (with [Type] suffix). The file contains special parameters influencing exporter behavior and automatically collected parameters from IFC property set definitions (collections from IFC2x2, IFC2x3, and IFC4)
219
219
<li>Various improvements for consistent geometry (conforming to Euler formula)
<li>This is the first version of IFC Export utility for Revit 2020.
370
-
<li>The functionality in this version is identical to the 19.2.0.1 version
370
+
<li>This is generally a bug fix release with some new IFC functionality.

New Export Functionality:
376
+
377
+
<ul>
378
+
<li>IFC Exporter now supports IFC Spatial Container assignment override using IfcSpatialContainer parameter. Valid values are: "IFCSITE", "IFCBUILDING", or name of the Building Storey
379
+
<li>Improved detection of Door operation type using the 2D swing symbol (arc). The improved version detects range of angles (not limited to 90, 180 or 360 degrees only)
380
+
<li>Added support for IfcCivilElement
381
+
<li>Replace IfcRelConnectsPortToElement with IfcRelNests for IFC4 export as recommended in IFC4 specifications, allowing non-IfcDIstributionElement to participates in the connectivity
382
+
<li>Added support for RampFlight and Run from generic models or family representing more complex Ramp for export to IfcRamp and IfcRampFlight
383
+
<li>Added various property Calculators
384
+
<li>Improve performance when exporting a large mesh
385
+
<li>Enable IFC Property Templates
386
+
<li>Allow multiple Property Template mapping from txt
387
+
<li>Projection improvement
388
+
<li>Enable site and project property creation
389
+
<li>Utilize Site GlobalId method
390
+
<li>Add multilanguage support files for German language (DE)
391
+
<li>Provide a complete list of all Shared Parameters used by Revit on export including ALL properties defined in IFC PropertySet Definition for both Instances and Types. The lists are included in the installer and will be placed in the install folder: IFC Shared Parameters-RevitIFCBuiltIn_ALL.txt (for the Instance parameters) and IFC Shared Parameters-RevitIFCBuiltIn-Type_ALL.txt (for the Type parameters).
392
+
<li>Improve consistency for setting the object direct attributes, support IfcObjectType[Type] special parameter to drive instance ObjectType parameter from the Type, update the shared parameter definition files (now for [Type] parameters we will also maintain the GUID as long as it remains)
393
+
<li>Incremental work towards IFC4RV 1.2 MVD
394
+
</ul>

Export Bug Fixes:
398
+
399
+
<ul>
400
+
<li>Consistent ExportAs entity and its PredefinedTypes
401
+
<li>Export fails when there is no associated Plan View to a level
402
+
<li>Additional fix for error getting 2D data when there is no Level associated to the FamilyInstance
403
+
<li>Various fixes related to missing geometry and export failures
404
+
<li>Fixed performance issue in IFC2x3 export due to error in creating types
405
+
<li>Fixed issue with slanted Pile
406
+
<li>Fixed issue related to element that is split into parts
407
+
<li>Improvement in handling level of Part Override
408
+
<li>Some improvements on classification (issue #31)
409
+
<li>Fixed issue on Composite curve tolerance (issue #5)
410
+
<li>Fixed issue where element is still exported even though it is set to not-exported in the mapping table
411
+
<li>Bugfix for incorrect cylindrical hollow core Beam export in IFC4RV
412
+
<li>Fixed for issue #51
413
+
<li>Bugfix based on Pull request #52 for MEP connector, and a few clean-ups
414
+
<li>Fixed minor issue to ensure generic element exporter will generate consistent GUID for the instance
415
+
<li>Fixed issue when OverrideElementContainment is used but the Site does not have site geometry (from Topography surface)
416
+
<li>Add support of OverrideElementContainment also for SpatialElement (Room/Space/Area). This enables export to place IfcSpace directly to IfcSite for example, which is useful for outdoor spaces
417
+
<li>Refactored the handling of valid entity and type and fixed a few defects related to it (Github issue #68)
418
+
<li>Fixed issue with Stair Landing that is offset far away from the supposed location
419
+
<li>Fixed issue with missing geometry when assigning IfcExportAs to the Spatial Element (Issue #23)
420
+
However, in IFC4RV or DTV, there is a fixed list of valid entities that will be enforced, entity such as IfcExternalSpatialElement will be exported as IfcBuildingElementProxy.
421
+
<li>Fixed performance issue when there is a large triangulated geometry for export to IFC4RV
422
+
<li>Fixed issue of exception raised during export when "Export schedules as property sets" option is selected, and the model contains ViewSchedule from the template
<li>Fixed issue in exporting IfcBuildingElementProxy that assigns an invalid enumeration for CompositionType in Ifc2x3 export
426
+
<li>Fixed issue related to opening that cuts through multiple walls (note that this is not yet 100%. In some cases, due to the extended body of the opening (that is defined in the native code) there may be more cut than it should for a few cases
427
+
<li>Fixed issue with changing GUID of Window or Door when it is in the context of the opening that cuts multiple walls (issue "IFC Guid on family" in SourceForge)
<li>Improve handling for multiple meshes in a tessellated geometry that causes missing some surface body.
430
+
<li>Fixed issues of UserDefined propertysets that fails to recognize the Pset assigned to a Type. Also improve the handling for Conditional Pset (by PredefinedType)
431
+
<li>Fixed regression issue #70 missing toprail for IfcRailing on export
432
+
<li>Fixed issue with "runaway" flex duct with "Keep Tessellated Geometry as Triangulation" option selected (issue #58)
433
+
<li>Fixed regression issue (issue #96) IfcZone ObjectType not exported
434
+
<li>Fixed issue of Naming override/default value, and issue of Qto_ properties are not exported
435
+
<li>Fixed issue on a wrong enumeration for the SweptArea (it was set to .CURVE., should be .AREA.)
436
+
<li>Fixed for orphaned entities and wrong footprint information due to incorrect projection direction for IFC4RV requirements. IFC4RV Beam (Arch) is now without error in the automated test
437
+
<li>1st fixed for issue related to runaway parts in "export only elements visible in view" (there are still situations that may cause a wrong rotation, but the test case reported in issue #86 so far looks good)
438
