Depuis quelques jours, l’application IFC pour Revit à été mise à jour (version 2016.6 et version 2017.3).
Rappel : cette application permet d’augmenter les capacités d’importation et d'exportation du logiciel Revit (contribution Autodesk et écosystème Open Source).
On peut même considérer qu'elle est indispensable pour tout utilisateur souhaitant exporter son projet Revit en IFC, ou importer un fichier IFC dans Revit : cette application vous permettra de choisir parmi de nombreux pré-paramétrages conformes aux normes IFC en vigueur, et de personnaliser vos imports et exports selon vos souhaits.
La principale information à retenir pour cette mise à jour IFC, c’est l'amélioration du support de la norme IFC4 (Import / Export).
Remarques :
- IFC Exportateur pour les versions de Revit 2013 à 2015 ne seront plus éligibles aux mises à jour régulières.
- IFC Exportateur pour les versions de Revit 2016 et 2017 inclut l'exportation, l'importation et l'interface utilisateur à l'exportation. Il n'y a pas besoin d'installations distinctes.
- Cette mise à jour fonctionne pour les versions Revit et Revit LT.
Voici la liste des apports de cette mise à jour :
Général :
- 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 (downloadable from http://www.buildingsmart-tech.org/ifc/IFC4/Add2/IFC4_ADD2.exp), 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 (export):
- 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 (import):
- 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.
