General - Initialize GUIDOptions so that GUIDUtil.CreateGUID(element) can be used outside of the exporter code. - Remove filterView argument from many functions; used cached value instead. - Various minor optimizations to slightly improve the time to export. New Functionality - (R2014 only) IFC4: Allow export of 0 thickness material layers. - (R2014 only) IFC4: Export IfcFootingType (IFC2x3: use IfcTypeObject instead) for wall-based footings only. - Allow export schedules as custom property sets. The name of the schedule is the property set name; the column names are the IFC parameter names. - Allow export of solid models, which allow for mixing Brep and extrusion geometries for an entity. This can result in smaller IFC files. - Export IfcCurtainWallType (IFC2x2: use IfcTypeObject instead). - Export the currently selected non-primary design option when exporting in current view only mode. - Use the base level parameter of an element to determine which level to associate the element to; use geometric containment only for cases where this is no base level. Bug Fixes - Don't export some extraneous local placements. - Don't export type if instance isn't exported for family. - Fix Pset_CoveringCommon: Thickness -> TotalThickness - Generic rework of how instance and type properties are assigned to IFC entities. If an exported entity has a related type object, then the entity will have the instance properties assigned, and the type object the type properties. If there is no type object, the exported entity will contain both instance and type properties. This should also remove any repetition of exported property sets. - Look at all "ZoneName X" shared parameters for a room even if some have no value. This still assumes that they are sequential (i.e., if there is no "ZoneName 4" shared parameter at all, "ZoneName 5" will not be processed). - Prevent export of IfcPolyLoops with less than 3 vertices. - Properly scale all known Revit parameter types to the units specified for the IFC file. Note that there are potentially many Revit parameter types that map to one unit type (e.g., PipeSize, WireSize, and Length are both length parameters); we do not create different units for each of these, but instead use the main unit type. - Respect visibility options of curtain wall panels and mullions when exporting in current view only mode. - Use category id as default for IfcCoverings for ceilings, floors, and roofs. |
New Functionality - Add UI version number to title of the IFC Export dialog box. - Add option to export schedules as custom property sets. The name of the schedule is the property set name; the column names are the IFC parameter names. - Add option to export solid models, which allow for mixing BRep and extrusion geometries for an entity. This can result in smaller IFC files. - Remove option to disable surface styles on export. - Remove option to export advanced swept solids. |
New Functionality: - Add property sets: Pset_ElectricalDeviceCommon, Pset_ - Add support for electrical current, electrical voltage, frequency, and positive plane angle units. - Allow Name/ObjectType/Description override for IfcSystem. - Allow using "IfcExportAs" = "DontExport" to remove an individual element or type from the export. - Export DuctLining. - Export Groups, including nested groups, as IfcGroup. - Export electrical systems and connectors. - Export local coordinate system for IfcDistributionPorts. - Export PipeInsulation. Bug Fixes: - Allow MEP zones to export Pset_ZoneCommon, fix 2 property names. - Correct export of parts for Coordination View 2.0. - Correct height of Revit Areas. - Correct material assignment for generic MEP exporter. - Correct units and unit scaling for volumetric flow rate. - Fix export of multi-storey stairs. - Get material for ducts and pipes from system. - Properly associate internal ElementType Revit property sets with IfcElementType, instead of adding to instances. - Properly scale door and window lining properties. - Protect against trying to add a null property to an IfcPropertySet. - Remove extraneous property sets when exporting Rebars. - Remove stale IfcSurfaceStyle and IfcPresentationStyleAssignment handles from caches for some aborted attempts to export items as multiple IfcExtrudedAreaSolid. - Return correct Boolean value for GetBooleanAtribute function. |
General: - 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. New Functionality: - Add 11 new IFC common parameter sets, including: Pset_AirTerminalTypeCommon, Pset_ - 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/ - 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/ Bug Fixes: - 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. |
