Known Issues

The version of the third party toolkit we use to read and write IFC files has a limit on the maximum size of IFC file it can create. While there is no absolute metric for this, in practice it is about 1.5GB. There is a newer version of the toolkit that removes this limitation, but we don't yet use it.

18.2.0	General: •Added extra UI and functionality to make COBie IFC exports easier. Specific improvements will be detailed below. •TODO: Some of the new fields will be localized to French in a future release.

18.1.0	General: - Minor improvements to the Importer class to make it easier for developers to create a custom Importer. - We now support the IFC4 Addendum 2 schema. Specific improvements based on that will be listed below. For this update, you will have to manually add the IFC4_Add2.exp file (included with this package), to the EDM subfolder of your Revit Program folder. We will automate this in a future update. New Export Functionality: - Allow overriding material names on export by using IfcName shared parameter. - Expand the use of types for many elements that didn't export types before, including beams (IfcBeamType), curtain walls (IfcCurtainWallType, and types for mullions and panels), and footings (IfcFootingType). - Improved ability to export some geometry as IfcSweptSolid. - Try to use axis information, if it exists, when exporting beams and members in addition to columns. - (IFC4) Better support beam, column, and member base quantities, including weight. - (IFC4) Collect material information for profiles for beams and columns. - (IFC4) Expand use of FootPrint representations to columns and slabs. - (IFC4) Expand use of IfcMaterialLayerSetUsage if the entity has a compound structure in Revit, as allowed by IFC. - (IFC4) No longer create StandardCase IFC entities, as these have been deprecated (including IfcWallStandardCase). - (IFC4) Support IfcMaterialConstituent and IfcMaterialProfileSet for a number of elements. - (IFC4) Use Built-in parameter "Structural_Bend_Dir_Angle" to get "Roll" property for PSet_BeamCommon and PSet_ColumnCommon. - (IFCAdd2) Support IfcPolygonalFaceSet. Export Bug Fixes: - Allow exporting to IFC while using Collaboration for Revit where the default directory isn't local. - Better support for MEP type entities, that didn't always export correctly. - Correct the parameters of the directrix of some IfcSweptSolids. - Fix correct mapping of IfcBurnerType/IfcGasTerminalType and IfcElectricHeaterType/IfcSpaceHeaterType. - Fix creation of types for sub-entities of IfcDistributionControlElement. - Fix offset problem when using the "Export Linked Files as Separate IFCs" option in locales where the decimal mark is not a point. - (IFC4) Correct names of IFC4 entity quantity sets. - (IFC4) Fix the name of IfcCommunicationsApplianceType. New Import Functionality: - Add support for IfcDerivedProfileDef. - Support IfcRelClassification. - (IFC4) Support IfcMaterialProfile, IfcMaterialProfileSet, and IfcMaterialProfileSetUsage. - (IFC4) Support IfcMaterialConstituent and IfcMaterialConstituentSet. - (IFC4) Support IfcTessellatedFaceSet and IfcPolygonalFaceSet. - (IFC4) Improve mapping from Roll parameter to structural bend direction angle. - (API only) Allow for two new options, CreateDuplicateZoneGeometry and CreateDuplicateContainerGeometry, that disable the duplication of geometry for zone elements and containers, respectively. Import Bug Fixes: - Better reporting when importing an IFC file with invalid rectangular or circular profiles (e.g., a 0 radius profile). - Don't show the void geometry when subtracting a void from an empty solid as a result of an IfcBooleanResult calculation. - Ensure that IFC2x schema files can still be imported. - Fix import of some IfcSurfaceCurveSweptAreaSolids.
