Export IFC Open Source de Revit 2013 – Mise à jour disponible !

Généralités :

– Clean up code dealing with door and window operation and construction type.

– Clean up code dealing with getting Solids from element geometry.

– Finalize support for FM Handover view.  The new functionality for this is included in the lists below.

– Replace native function call to create some columns as extrusions with .NET code.

– Renamed the shared parameters for many entity properties to have "Ifc" at the front.

– Sort parameter names on export to minimize changes in IFC file from subsequent exports of the same file.

Nouvelles fonctionnalités :

– Add 11 new IFC common parameter sets, including: Pset_AirTerminalTypeCommon, Pset_DistrubutionFlowElementCommon, Pset_FlowTerminalAirTerminal, Pset_SpaceOccupancyRequirements, Pset_PlateCommon, Pset_ReinforcingBar*Common

– Add support for IfcLengthMeaure parameter export.

– Add support IfcCircleHollowProfileDef; use for extrusions if appropriate.

– Add support for Provisions for Voids.

– Allow specification and export of a user-defined classification system, instead of just Uniformat.

– Allow exporting elements as IfcDiscreteAccessory/IfcDiscreteAccessoryType.

– Allow "IfcExportAs" to take both the entity name and the type name in the format "IfcEntityName.TypeName".

– Export base quantities for 5 elements: IfcBuildingStorey, IfcCovering, IfcDoor, IfcSpace, IfcWindow.  Some of these were already supported and were just moved from native to .NET.

– Export FabricArea and FabricSheet as IfcReinforcingMesh and IfcGroup, respectively. 

                – Note: that the default export settings have these set as "Not Exported" – these have to be updated manually to "IfcReinforcingMesh" and "IfcGroup".

– Export ceilings as extrusions or BReps if possible, instead of just surface models.

– Export surface styles by default for Coordination View 2.0.

– Include Ceiling as a room bounding element on export if it is part of only one room.

– Stabilise GUIDs for Pset_Building/BuildingStorey/SiteCommon, internal Revit property sets, and slabs in roof containers (only for  the case of an IfcRoof containing a single IfcSlab, however).

Corrections de bugs :

– Changed incorrect "PSet" to correct "Pset" for various parameter set names.

– Don't create openings for doors and windows when the host is exported as parts

– Don't export RepresentationMap for IfcTypeProduct with 0 items.

– Don't ignore an internal Revit parameter on export if it has the same name as a parameter in another group.

– Export materials for IfcReinforcementBar; make body representation "AdvancedSweptSolid".

– Fix export of grids so that only one IfcShapeRepresentation is created.

– Fix export of some extruded columns that were split into separate components by other elements.

– Fix issue where classification reference was not exported in non-English versions of Revit.

– Make "NosingLength" parameter of PSet_StairFlightCommon IfcLengthMeasure.

– Make GetExportTypeFromClassName not reject some unrecognized IFC class names.

– Move the local placement of many entities with extrusions and mapped representations for geometry to be closer to the geometry.

– Properly export Pset_ZoneCommon for IfcZones.

– Properly label some mislabelled IfcOpeningElements as "Opening" or "Recess".

– Properly scale door panel properties, window frame properties, and base quantities on export.

– Remove incorrect PsetLightFixtureCommon.ArticleNumber property.

Nouvelles fonctionnalités :

– Add a "Classification" tab to allow specification and export of a user-defined classification system, instead of just Uniformat.

– Allow choice of whether to include the elevation offset of IfcSite in the local placement of the IfcSite as a UI option.  By default, the elevation offset is NOT included in the local placement as of version 2.7/1.7 of the exporter.  Note that currently this override is disallowed for Coordination View 2.0 files; if there is a demand for this, we will consider allowing it with a comment in the IFC file itself.  Note that this UI change needs Exporter v2.8 to work properly.

– Export surface styles by default for Coordination View 2.0.
